ac plus two separate display screens brands

Unifying video and audio connections in a single HDMI cable may have simplified home theater setups for the majority of people, but some of us home theater masters and PC power users still find ways to complicate things. For example, if you want to send a single video source to multiple TVs or monitors, you’ll need to use an HDMI splitter, which duplicates or “mirrors” from a single HDMI “in” connection, and provides multiple HDMI “out” ports so you can plug in many displays. Of course, HDMI splitters can cost as little as a few dollars or run into the hundreds. They can offer a wide range of different capabilities depending on your needs. A quick search on your favorite shopping site will also reveal that there are a lotof them to choose from, which can make it tricky and frustrating to find a good one. We’ve collected some of the best HDMI splitters for dual monitors, and more, currently available right so you don’t need to guess which one will work well.

Unlike 4K TVs or gaming monitors, there isn’t a library of in-depth professional reviews on HDMI splitters for dual monitors that you can quickly turn to for trusted recommendations. Luckily, I’ve covered A/V gear for publications like Engadget, Popular Mechanics, and Reviewed, so I can step in and make some recommendations based on personal experience and hands-on time using them. In addition to my own testing, I turned to user impressions from comment sections and feedback in enthusiast forums so I could learn more about the quirks of each individual product.

Before you buy an HDMI splitter for dual monitors, you should have a plan. This is a specific little accessory that does a very specific thing. If you don’t have a device, like a game console, cable box, or PC, that you want to show on multiple monitors simultaneously, you should hold off on buying this until such a need arises.

If you are looking for a device that allows you to plug multiple devices into a single HDMI port, you’re actually looking for an HDMI switcher, rather than a splitter. There’s also a wide range of HDMI adapters that convert signals to different kinds of ports. We totally understand if you got mixed up: Terms like splitter, switch, or adapter are sometimes used interchangeably, but they refer to completely different things. It certainly doesn’t help that HDMI switchers often come up in search results for HDMI splitters, and vice versa.

Like we said, a lot of people, including manufacturers and retailers, play it fast and loose with A/V terms like “HDMI splitters.” Technically, HDMI splitters turn one HDMI signal into many identical HDMI signals. It’s HDMI end-to-end, and all they can do is mirror the screen.

That said, there is also a category of HDMI adaptersthat can plug into a laptop via USB Type-A, USB-C, or Mini DisplayPort, and output to two monitors. These adapters willgive you a more robust set of display options, including an extended desktop across multiple displays. (They can also mirror your laptop across multiple displays.) Usually, these accessories will be called adapters, because they take one connection type and convert it into another. In some cases, they will also be called HDMI splitters, either because that’s what people expect them to be called, or because they want to make our lives harder.

We realize that there is a very real possibility that you’re actually looking for an HDMI adapter that can serve as a splitter so you can plug your laptop into a dual-monitor setup. Rest assured: We have recommendations for both conventional HDMI splitters and various adapters that output video to two HDMI ports.

HDMI splitters are fairly simple devices but they don’t all have the same capabilities. First and foremost, figure out how many video-out ports you need. Personally, I’d suggest mapping out your exact setup, including the positions of each monitor or TV and the video source, as well as a cable management plan for your HDMI cables.

All of this also applies to HDMI adapters that can output dual-HDMI signals. Most adapters will not be able to handle the same bandwidth as a direct HDMI 2.1 or DisplayPort 1.4 connection. Refresh rates, in particular, will likely take a pretty serious hit going through an adapter. On the plus side, most HDMI adapters we’re aware of will take power from your laptop, so there’s no need to plug them in independently.

Our recommendations for the best HDMI splitters range from basic and inexpensive options to pricier, more capable devices for advanced home theaters or commercial setups. Whether you’re looking to feed video to two displays or eight, you’re sure to find a solution here to meet your needs and make sure the equipment mounted on your sturdy workstation works its best.

Why it made the cut:OREI’s UHD-PRO102 does almost everything we want in an HDMI splitter, supporting high resolutions and scaling automatically in a compact, affordable package.

It costs a little more than a basic HDMI splitter, but the OREI UHD-PRO102 HDMI Splitter is still fairly inexpensive and offers just about all of the capabilities you’ll need if you’re simply looking for a splitter with two HDMI outs. It supports resolutions up to 4K at 60Hz and automatically scales your video source to match the resolution of each screen. It requires independent power via Micro USB, and OREI does include a wall adapter, which isn’t a given with some of the cheapest splitters.

Why it made the cut: An upgraded version of our top overall pick, the OREI UHDPRO-104 matches does all the same things right, while adding support for two more displays.

If you need to mirror more than two displays, OREI also makes an equally effective 4-output version of our top overall pick. The OREI UHDPRO-104 offers all of the same key specs as the dual HDMI-out version, including support for 4K at 60Hz along with automatic scaling to match your TV’s resolution and, just like the OREI UHD-PRO102, it’s powered via Micro USB with a wall adapter included in the package. As you’d expect, this one is larger than the two-out model, but it is about as compact as a 4-output splitter can be and you shouldn’t have any trouble tucking it away out of sight. It’s also substantially more expensive but, again, you’ll be able to mirror twice as many displays.

If you need to split your image among eight displays, Tripp Lite makes the splitter for the job. It’s considerably more expensive than the others but it’s also capable of outputting a video source to eight screens in 4K at up to 60Hz. It’s a suitably heavy-duty unit with all-metal construction, and it even comes with mounting hardware if you want to attach it to a wall or a desktop.

One small issue, considering the expense: Tripp Lite recommends you keep the HDMI cables to no longer than 15 feet to ensure the best performance. Even with that issue, though, it’s a small compromise to make if you want to get your image on eight screens at once.

While it may feel like overkill, Targus’ USB-C Dual 4K HDMI adapter is a stellar, relatively affordable USB hub that can both mirror your laptop display or “extend” it across multiple monitors. There are plenty of dedicated USB-C-to-HDMI adapters out there, but many of them come with caveats: Some either limit 4K playback to 30Hz. Others only support Windows. Meanwhile, Targus’ portable hub turns a single video-enabled USB-C port into two HDMI ports that support 4K at 60Hz, plus two standard USB 3.1 ports, an Ethernet port, and both SD and Micro SD card readers. Only one of the USB ports supports fast-charging, which is annoying because you’ll need to remember which one, but you’re adding a ton of functionality to your laptop, and it only costs a little bit more than a simple USB-C-to-HDMI adapter.

Why it made the cut:While it has a few drawbacks, this adapter from C2G is a better option than standard USB adapters for Mini DisplayPort-enabled devices.

Have a laptop with a Mini DisplayPort but no video-capable USB-C port? This adapter from C2G will let you easily mirror or extend your display and should give you better performance than an adapter that simply relies on standard USB. Unfortunately, while it supports mirroring across all laptops, it can only output extended displays on Windows systems. The company also notes that the adapter may require external power by plugging it into a spare USB port on your computer “in some instances.”

The Avedio Links HDMI Splitter might be inexpensive, but it will easily get the job done for anyone that doesn’t have especially demanding needs. It’s small enough to easily be tucked away, and it’s USB-powered, which means you can use either a wall adapter (which isn’t included) or a spare USB port if you have one. The two HDMI outs will handle video up to 4K, although the splitter only supports 30Hz at that resolution—you’ll need to drop down to 1080p for 60Hz.

Any HDMI splitter will let you use two monitors, but it will only mirror the image on both displays. To “extend” your display, or expand your desktop to span two monitors, you will need to use an adapter or USB-C hub that converts video out from a compatible port, such as a Thunderbolt or DP Alt Mode-enabled USB-C port, or Mini DisplayPort, to a dual-HDMI connection.

Depending on your computer, you may also simply be able to connect two monitors using two separate ports. Most desktops, particularly gaming PCs, support multiple DisplayPort and HDMI connections. Some laptops may feature a single HDMI and a video-capable USB-C port.

At this point, most HDMI splitters (or adapters) can output your PC to multiple screens at up to 4K resolution, so you shouldn’t lose any visual fidelity. That said, most splitters and adapters will cap and reduce your PC’s refresh rate to 30 or 60Hz, which may be well below your PC and monitors’ capabilities.

An HDMI splitter takes the signal from a single source (like a streaming device, game console, or 4K Blu-ray player) and sends it to TVs or monitors, so you can watch the same image on many screens at once.

Clearly, HDMI splitters can be a very confusing topic, but sometimes you just need one. Whether you’re actually looking for a proper HDMI splitter or an adapter to create a dual-monitor setup with a compatible laptop, make sure you figure out exactly what you want before you buy anything. It is especially easy to buy the wrong thing and get discouraged or frustrated, so we hope our guide to HDMI splitters for dual monitors has helped clear the confusion.

Who this is for: A dual-monitor setup is usually the best option if you want to have a bunch of app windows open at once. But an ultrawide model might be a better choice if you need a ton of unbroken horizontal space, or you don’t want monitor bezels in between windows.

Why we like it: The Dell P3421W has a sturdy adjustable stand, lots of ports (including a USB-C port that can handle power, display, and data over a single cable), and a three-year warranty. And it has a built-in KVM switch that allows you to easily swap your keyboard, mouse, and video between two computers. The 1440p display has a 60 Hz refresh rate, which is great for typical office work, web browsing, and casual gaming.

Flaws but not dealbreakers: If you use your display in direct sunlight, this monitor might not be bright enough for you. It can also provide 65 W of power over USB-C, but some laptops require more. If you have a laptop with an Nvidia GeForce RTX GPU or an Intel Core i7 processor, you might need to keep the laptop plugged in to a separate charger or use a Thunderbolt dock that can provide the extra power.

Most ultrawide monitors are also curved. This design helps minimize viewing-angle problems—when you’re sitting centered, things on the far edges of the screen won’t look as washed out as they would on a flat display of a similar width. But this also makes ultrawide monitors inaccurate for precision tasks requiring straight lines, such as drawing, photo editing, or similar design work.

Check the specifications of your laptop for information regarding the number of displays it can support and the type of connections the laptop has available, such as HDMI, USB, Thunderbolt, etc.

Typically, there will be at least one connection available from the laptop for another display such as HDMI or VGA. You can connect your first external monitor to this connection to get a second display.

For a third display, you will typically need a docking station to add more ports to the laptop. There are universal docking stations that will work with most systems.

You may also need to install drivers onto the computer for the dock to fully function. The dock may include an installation CD, otherwise please refer to the manufacturer’s website for downloadable drivers.

You will now see three monitors available to select and arrange. Scroll down until you see the Multiple displayssection to ensure that you have it set to Extend these displays to extend the display across the monitors.

Return to the Select and rearrange displays area and select the Identify button. A large number will appear on each display to correspond to the display settings numbers to identify each monitor. This will help with arranging the monitors in the settings to ensure they are extending properly between laptop and external monitors.

USB Type-C (or USB-C) is a new, smaller and very versatile connector with a reversible-plug that is capable of carrying data, video and power. USB Type-C is expected to eventually replace the USB Type-A and Type-B connectors currently in use. USB Type-C connectors are used in USB 2.0, USB 3.0 (also described as USB 3.1 Gen 1) and USB 3.1 Gen 2 (10Gbps) applications.

Your device must have a USB Type-C port to accept a Type-C connector. Older USB devices can connect to a Type-C compatible phone, tablet, or laptop using an adapter cable (e.g. Type-C connector on one end and a Type-A or Type-B connector on the other). Some devices with USB Type-C ports still use the older USB 2.0 or USB 3.0 (also described as USB 3.1 Gen 1) standards. If you have a device with a USB Type-C port running USB 3.1 Gen 2 (10Gbps), you can still use older peripherals since USB 3.1 Gen 2 is backwards compatible with USB 3.0 (also described as USB 3.1 Gen 1), USB 2.0 and USB 1.1. Conversely, if you have a SuperSpeed+ peripheral with a Type-C connector, you can connect it to a Type A port running USB 3.0 (also described as USB 3.1 Gen 1), USB 2.0 and USB 1.1.

DisplayPort is a high-performance digital interface for transmitting audio and video signals. It was developed to replace older technologies, such as VGA and DVI, and has become one of the most advanced display technologies.

It is important that the host PC allows for administrator access when connecting the dock for the first time in order to allow the automatic driver installation to take place. If this is not an option please see the product"s web page on www.tripplite.com to download the drivers manually.

This multiport USB-C dock expands the potential of your Windows or Apple laptop or other device with a USB-C or Thunderbolt 3 port. It’s ideal for transmitting digital audio and video to a large display, adding a thumb drive or other USB peripheral, powering and charging a PD Charging-compliant mobile device, connecting to a Gigabit Ethernet network and a lot more—all at the same time.

By connecting the built-in USB-C cable to a source device that supports USB DisplayPort Alt Mode, you can output 4K video and digital audio to a monitor, television or projector without installing special software drivers.

The Mini DisplayPort (mDP) and HDMI outputs support Ultra HD video resolutions up to 3840 x 2160 (4K x 2K) at 30 Hz. The VGA output supports HD resolutions up to 1920 x 1200, including 1080p, at 60 Hz. A DisplayPort or DVI display may also be connected using an mDP to DP or HDMI to DVI adapter (adapters sold separately).

Connecting two external monitors simultaneously allows you to display the same image on both monitors, extend your host desktop across both with different windows open on each, or combine both into one large display as a video wall. Connect dual monitors in Extended (4K @ 30 Hz mDP with 1080p HDMI or 720p VGA) and Mirror (1080p mDP with 1080p HDMI or 1080p VGA) modes. HDMI and VGA video ports will not work simultaneously.

The USB-A hub ports accept up to three USB peripherals, such as flash drives, mice, keyboards and printers. They support fast USB 3.2 Gen 1 data transfer rates up to 5 Gbps and are backward compatible with USB 2.0 and USB 1.1 devices. The total charging output of the three ports is 10 Watts, with one port supporting 5V/1.5A (7.5W) fast charging. The other two ports share 5W max. Note: Host must support USB OTG (On-the-Go).

The USB-C Power Delivery port supports power output up to 20V 5A (100W), which is sufficient for charging and powering the connected source device, such as an Android smartphone or Chromebook. Just connect the device’s AC wall charger to the USB-C PD port. Note: USB-C PD port does not support Quick Charge (QC).

The RJ45 port offers access to a Gigabit Ethernet network when no Wi-Fi is available or when a wired connection offers faster speeds. Connect using a UTP cable (sold separately), and enjoy true 10/100/1000 Mbps Ethernet speeds for fast data transfers.

The USB-C dock’s 3.5 mm mini stereo jack is convenient for connecting speakers, headphones or a microphone to your workstation. You can listen to music or record the latest episode of your podcast.

The plug-and-play USB-C dock for Windows laptops, Chromebooks and other devices requires no software or external power. Drivers will install automatically the first time the dock is connected (Note: the host computer must have administrative rights or the drivers may fail to install correctly). The compact unit fits easily into a pocket, briefcase or laptop bag for connecting on the go.

When two monitors are connected with different resolutions, the monitor with the lower resolution may not function due to a limitation of 10.8G total bandwidth between the two displays

Trying to boost your productivity with a second screen? Want more immersive gaming sessions? Multiple monitors can help. Dual displays are great for multitasking and are easy to set up, but there are a few things to consider before you wade into a multiscreen world—whether you"re on Windows or Mac.

Windows: The presence of several ports on your graphics card indicates it can likely handle multiple monitors. But you should check the maximum number of supported displays and resolutions. (You can see what graphics card you have by typing Device Manager into the Search bar, opening it, and then expanding Display adapters.) Visit the manufacturer’s website to find the specifications for your graphics card, and look for a section titled Display Support or something similar that will list this info.

Mac: If you"re adding monitors to a Mac, click on the Apple icon > About This Mac and double-click your serial number, then tap Command-C on your keyboard to copy it, go to Apple"s website, and paste it into search. Click on Support to find the Technical Specifications and search for Video Support.

You can mix and match the types of screens you have at your workstation, though you"ll likely want some consistency. The most common monitor size is 24 inches, but 27-inch screens are increasingly popular. Having the same size screens will be nice for symmetry. Just keep an eye on resolution when you buy. A 1080p screen on a 27-inch monitor might look too fuzzy.

We dive into orientation and arrangements below, but consider different types of screen arrangements. My current preference is a 34-inch ultrawide screen paired with a 27-inch screen in portrait orientation. As the name suggests, ultrawides are really wide and can deliver the experience of two screens, minus the screen"s bezel in between. Pairing it with a screen in portrait mode means you get enough space on the ultrawide to run two full-size browser windows side by side, plus a vertical screen on the side for apps that benefit from it, like Slack and email.

Alternatively, you can mount your screen to your desk and get rid of the stand, freeing up a lot of space. (You can also freely move your screen to various angles and positions.) Many displays support the VESA mount system. There are different sizes, and monitor arms have a screen size range and maximum weight they can support. Always check whether the monitor"s product page mentions VESA support, and note the VESA mount size. When you buy an arm mount, make sure it supports the screen size and weight of your new screen.

To get the most from your computer and monitors, you"ll need to think about which ports and cables to use. For Windows PCs, your choice is often HDMI vs. DisplayPort. Unfortunately, this isn’t as straightforward as you might expect. There are several versions of each connection type, each with different capabilities. For example, HDMI 2.1 supports up to 8K resolution at 120 Hz, DisplayPort 1.4 can deliver 8K at 60 Hz, and HDMI 2.0 is limited to 4K at 60 Hz.

For laptops, you might be looking at Thunderbolt, Mini DisplayPort, or even USB-C. Sometimes you will need an adapter or USB hub to connect an external monitor.

Check the technical specifications for your graphics card and monitor to find the best option for you. Remember that the card, monitor, and cable (and any adapters) you use must support the same technology and the same version. High-end monitors usually come with a selection of cables in the box, but some manufacturers annoyingly provide a single option that might not match the monitor’s top capability.

You may be able to connect one or more external displays to your Mac (you may need a video cable or adapter for each display). See the Apple Support article Adapters for the Thunderbolt 4, Thunderbolt 3, or USB-C port.

For each display, securely connect a video cable (and adapter, if necessary) from a video output port on your Mac to the video input port on the display. See About the video ports.

You can connect one or more external displays, depending on your Mac.For Mac computers with the Apple M1 Chip: You can connect a single external display to your Mac. Docks don’t increase the number of displays you can connect. On a Mac mini with M1 chip, you can connect a second display to the HDMI port. See the Apple Support article Mac computers with Apple silicon.

For Mac computers with Thunderbolt 3 (USB-C): You can connect a single display to each port. If you connect multiple Thunderbolt devices to each other, the Thunderbolt 3 display must be the last device in the chain. If your Thunderbolt 3 display has USB ports, those can be used for data and power.

For Mac computers with Mini DisplayPort, Thunderbolt, or Thunderbolt 2: You can connect up to two displays. If the displays themselves have Thunderbolt ports, you can connect one display to another, and then connect one of the displays to a Thunderbolt port on your Mac. If your Mac has two Thunderbolt ports, you can connect each display to separate Thunderbolt ports on your Mac. A DisplayPort device must be the last device in a chain of connected Thunderbolt devices. See Connect a display, TV, or projector to Mac.

For Mac computers with Thunderbolt 4 (USB-C) and HDMI ports: You can connect up to four external displays to your Mac, depending on your Mac model. See the Apple Support article Connect a display to your Mac.

Note:Only the device directly connected to your Mac receives power from the computer’s Thunderbolt port. The other devices in the chain must be powered by separate power adapters.

You can arrange your displays in any configuration to create an extended desktop. For example, you can set your external display side by side with your Mac to create one large continuous desktop.

If more than two displays are connected to your Mac, you can specify that some displays use mirroring (showing the entire desktop) and other displays show the extended desktop (displaying the desktop across two or more displays). For example, if you have three displays, you can have two displays showing the same information and the third display showing the extended desktop.Press and hold the Option key and drag one display icon onto another display icon to mirror those two displays.

Your laptop or PC has a DisplayPort-compatible graphics card with Multi-Stream Transport (MST) support, and now you want to add multiple external monitors. With an MST Hub, this is a simple task.

First introduced in the DisplayPort 1.2 standard, Multi-Stream Transport allows multiple displays to be connected to a single DP port on a desktop PC or laptop. It does this by combining multiple video signals into a single stream (a process known as multiplexing) and sending it over a DisplayPort cable to a device that unbundles the signal. The "unbundling" device might be an MST Hub or a series of "daisy-chained" MST monitors.

The DisplayPort 1.2 specification includes support for two transport modes: Single-Stream Transport (SST) and Multi-Stream Transport (MST). With the introduction of MST, which combines multiple video signals into a single stream, the default method of transmitting video as a single stream to one monitor was renamed Single-Stream Transport (SST).

DisplayPort MST lets you daisy-chain monitors with DisplayPort 1.2 ports (each monitor must have a DP output port that supports MST). Daisy chaining means connecting your laptop to monitor A, then connecting monitor A to monitor B and so on. The number of monitors you can daisy-chain is limited and depends on the resolution and frame rate. The last monitor in the chain does not need to support DP MST.

The first monitor in the chain, the one connected to your laptop or PC, must have DP 1.2 ports in and out. DisplayPort Out on the first monitor is connected to the second monitor, which needs to have a DP in port. Alternately, you can use a DP adapter or adapter cable to convert the signal to some other standard such as HDMI. Don"t forget to verify that you graphics card and first monitor support DP 1.2 and it is enabled.

A DisplayPort MST hub offers the most flexibility. For example, you can connect up to 4 HDMI monitors or televisions. You can also create a video wall, making a hub ideal for digital signage in schools, churches, conference rooms, trade shows and retail outlets.

MST-compliant DisplayPort graphics cards have limited bandwidth. An MST hub will split this total bandwidth between the connected monitors, with 1080p monitors consuming approximately 22% of bandwidth and 4K monitors using 40% or more. For example, this means you can connect up to 4 monitors with a resolution of 1080p to a DP 1.2 port.

An MST Hub supports three different modes for multi-monitor displays: duplicating your primary display, extending your display across multiple monitors, or creating a video wall.

Also called cloning or duplicating your display, in duplicate mode the same image will be displayed on each monitor. Duplicating a display is useful in settings such as retail environments with in-store product promotion screens; arrival and departure boards in airports, bus terminals and train stations; video presentations in classrooms, churches or auditoriums and multiple information booths and kiosks at trade shows. Duplicate mode is backward compatible with DisplayPort 1.1, so it can even be used with many older graphics cards.

Extending your display allows you to show your PC"s desktop on all of the connected monitors, while having a different window open on each monitor. The monitors still function as separate displays, but your usable workspace is extended and you can easily multitask and even move things around from one screen to another. You will be able to work on multiple documents at the same time, boosting your productivity. Extended mode is especially useful in presentations when you want to display notes or reference data on one screen while performing a demonstration or showing a video on another screen.

Creating a video wall lets you combine all monitors in your setup so they act as one giant monitor. You can arrange the monitors however you want them: vertically, horizontally or clustered together. In multi-stream video wall mode, the monitors will correctly display your content to create a dazzling, eye-catching presentation. Create a panoramic digital sign or wow the crowd at your next trade show. Three monitors aligned horizontally also make for a super-wide-screen gaming experience. A computer with a DisplayPort 1.2-compatible graphics card (such as AMD Radeon with AMD Eyefinity technology) is required to display in video wall mode.

Tripp Lite has MST Hub solutions with built-in converters to support HDMI and DVI monitors, as well as DisplayPort monitors. You"ll also need the compatible cables to connect the hub to your monitors; we recommend the following cables:

MST hubs are compatible with DisplayPort 1.2 standards, but to ensure full functionality, check your graphic card"s documentation to confirm it supports the features you need. For example, some graphics cards - particularly older DisplayPort 1.1 models - are limited to the duplicate mode. Others support duplicate and extended modes, but not video wall mode. Finally, be aware Mac OS X does not support MST for NVIDIA and Intel Graphics Processor Units; you will be able to use the duplicate mode, but not extended or video wall modes.

A laptop computer or notebook computer, also known as a laptop or notebook for short, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat panel screen (usually 11–17 in or 280–430 mm in diagonal size) on the inside of the upper lid and an alphanumeric keyboard and pointing device (such as a trackpad and/or trackpoint) on the inside of the lower lid, although 2-in-1 PCs with a detachable keyboard are often marketed as laptops or as having a "laptop mode".webcam at the top of the screen and some modern ones even feature a touch-screen display. In most cases, unlike table computers which run on mobile operating systems, laptops tend to run on desktop operating systems which have been traditionally associated with desktop computers.

Laptops run on both an AC power supply and a rechargeable battery pack and can be folded shut for convenient storage and transportation, making them suitable for mobile use.business trips), in education, for playing games, web browsing, for personal multimedia, and for general home computer use.

The names "laptop" and "notebook" refer to the fact that the computer can be practically placed on (or on top of) the user"s lap and can be used similarly to a notebook. As of 2022, in American English, the terms "laptop" and "notebook" are used interchangeably;notebook" originally referred to a specific size of laptop (originally smaller and lighter than mainstream laptops of the time),

Laptops combine many desktop components and capabilities into a single unit, including the central processing unit (CPU), random-access memory (RAM), hard disk drive (HDD) or solid-state drive (SSD), and graphics processing unit (GPU). Most modern laptops include a built-in webcam and microphone, and many also have touchscreens. Laptops can be powered by an internal battery or an external power supply by using an AC adapter. Hardware specifications may vary significantly between different types, models, and price points.

Design elements, form factors, and construction can also vary significantly between models depending on the intended use. Examples of specialized models of laptops include rugged notebooks for use in construction or military applications, as well as low-production-cost laptops such as those from the One Laptop per Child (OLPC) organization, which incorporate features like solar charging and semi-flexible components not found on most laptop computers. Portable computers, which later developed into modern laptops, were originally considered to be a small niche market, mostly for specialized field applications, such as in the military, for accountants, or traveling sales representatives. As portable computers evolved into modern laptops, they became widely used for a variety of purposes.

As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The first "laptop-sized notebook computer" was the Epson HX-20,Suwa Seikosha"s Yukio Yokozawa in July 1980,COMDEX computer show in Las Vegas by Japanese company Seiko Epson in 1981,LCD screen, a rechargeable battery, and a calculator-size printer, in a 1.6 kg (3.5 lb) chassis, the size of an A4 notebook.

The portable micro computer Portal of the French company R2E Micral CCMC officially appeared in September 1980 at the Sicob show in Paris. It was a portable microcomputer designed and marketed by the studies and developments department of R2E Micral at the request of the company CCMC specializing in payroll and accounting. It was based on an Intel 8085 processor, 8-bit, clocked at 2 MHz. It was equipped with a central 64 KB RAM, a keyboard with 58 alphanumeric keys and 11 numeric keys (separate blocks), a 32-character screen, a floppy disk: capacity = 140,000 characters, of a thermal printer: speed = 28 characters / second, an asynchronous channel, asynchronous channel, a 220 V power supply. It weighed 12 kg and its dimensions were 45×45×15cm. It provided total mobility. Its operating system was aptly named Prologue.

The Osborne 1, released in 1981, was a luggable computer that used the Zilog Z80 CPU and weighed 24.5 pounds (11.1 kg).cathode-ray tube (CRT) screen, and dual 5.25 in (13.3 cm) single-density floppy drives. Both Tandy/RadioShack and Hewlett-Packard (HP) also produced portable computers of varying designs during this period.flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The US$8,150 (equivalent to $22,880 in 2021) GRiD Compass 1101, released in 1982, was used at NASA and by the military, among others. The Sharp PC-5000,Gavilan SC released in 1983. The Gavilan SC was described as a "laptop" by its manufacturer,Toshiba T1100 won acceptance not only among PC experts but the mass market as a way to have PC portability.

While the terms laptop and notebook are used interchangeably today, there are some questions as to the original etymology and specificity of either term. The term laptop appears to have been coined in the early 1980s to describe a mobile computer which could be used on one"s lap, and to distinguish these devices from earlier and much heavier portable computers (informally called "luggables"). The term notebook appears to have gained currency somewhat later as manufacturers started producing even smaller portable devices, further reducing their weight and size and incorporating a display roughly the size of A4 paper;notebooks to distinguish them from bulkier mainstream or desktop replacement laptops.

There were in the past a number of marketing categories for smaller and larger laptop computers; these included "subnotebook" models, low cost "netbooks", and "ultra-mobile PCs" where the size class overlapped with devices like smartphone and handheld tablets, and "Desktop replacement" laptops for machines notably larger and heavier than typical to operate more powerful processors or graphics hardware.gaming laptop" or a "mobile workstation" for professional use.

The latest trend of technological convergence in the portable computer industry spawned a broad range of devices, which combined features of several previously separate device types. The hybrids, convertibles, and 2-in-1s emerged as crossover devices, which share traits of both tablets and laptops. All such devices have a touchscreen display designed to allow users to work in a tablet mode, using either multi-touch gestures or a stylus/digital pen.

Convertibles are devices with the ability to conceal a hardware keyboard. Keyboards on such devices can be flipped, rotated, or slid behind the back of the chassis, thus transforming from a laptop into a tablet. Hybrids have a keyboard detachment mechanism, and due to this feature, all critical components are situated in the part with the display. 2-in-1s can have a hybrid or a convertible form, often dubbed 2-in-1 detachable and 2-in-1 convertibles respectively, but are distinguished by the ability to run a desktop OS, such as Windows 10. 2-in-1s are often marketed as laptop replacement tablets.

2-in-1s are often very thin, around 10 millimetres (0.39 in), and light devices with a long battery life. 2-in-1s are distinguished from mainstream tablets as they feature an x86-architecture CPU (typically a low- or ultra-low-voltage model), such as the Intel Core i5, run a full-featured desktop OS like Windows 10, and have a number of typical laptop I/O ports, such as USB 3 and Mini DisplayPort.

2-in-1s are designed to be used not only as a media consumption device but also as valid desktop or laptop replacements, due to their ability to run desktop applications, such as Adobe Photoshop. It is possible to connect multiple peripheral devices, such as a mouse, keyboard, and several external displays to a modern 2-in-1.

Microsoft Surface Pro-series devices and Surface Book are examples of modern 2-in-1 detachable, whereas Lenovo Yoga-series computers are a variant of 2-in-1 convertibles. While the older Surface RT and Surface 2 have the same chassis design as the Surface Pro, their use of ARM processors and Windows RT do not classify them as 2-in-1s, but as hybrid tablets.mobile operating system, such as Android. These include Asus"s Transformer Pad devices, examples of hybrids with a detachable keyboard design, which do not fall in the category of 2-in-1s.

In general, laptop components are not intended to be replaceable or upgradable by the end-user, except for components that can be detached; in the past, batteries and optical drives were commonly exchangeable. This restriction is one of the major differences between laptops and desktop computers, because the large "tower" cases used in desktop computers are designed so that new motherboards, hard disks, sound cards, RAM, and other components can be added. Memory and storage can often be upgraded with some disassembly, but with the most compact laptops, there may be no upgradeable components at all.

Laptop screens most commonly employ liquid-crystal display (LCD) technology, although use of OLED panels has risen substantially since 2020.Low-voltage differential signaling (LVDS) or embedded DisplayPort protocol.

In the past, there was a broader range of marketing terms (both formal and informal) to distinguish between different sizes of laptops. These included Netbooks, subnotebooks, Ultra-mobile PC, and Desktop replacement computers; these are sometimes still used informally, although they are essentially dead in terms of manufacturer marketing.

As of 2021, mainstream consumer laptops tend to come with 11", 13" or 15"-16" screens; 14" models are more popular among business machines. Larger and smaller models are available, but less common – there is no clear dividing line in minimum or maximum size. Machines small enough to be handheld (screens in the 6–8" range) can be marketed either as very small laptops or "handheld PCs," while the distinction between the largest laptops and "All-in-One" desktops is whether they fold for travel.

Having a higher resolution display allows more items to fit onscreen at a time, improving the user"s ability to multitask, although at the higher resolutions on smaller screens, the resolution may only serve to display sharper graphics and text rather than increasing the usable area. Since the introduction of the MacBook Pro with Retina display in 2012, there has been an increase in the availability of "HiDPI" (or high Pixel density) displays; as of 2022, this is generally considered to be anything higher than 1920 pixels wide. This has increasingly converged around 4K (3840-pixel-wide) resolutions.

External displays can be connected to most laptops, with most models supporting at least one.USB4 (section Alternate Mode partner specifications)|DisplayPort Alt Mode]] has been utilized to charge a laptop and provide display output over one USB-C Cable.

The earliest laptops known to feature a display with doubled 120 Hz of refresh rate and active shutter 3D system were released in 2011 by Dell (M17x) and Samsung (700G7A).

A laptop"s CPU has advanced power-saving features and produces less heat than one intended purely for desktop use. Mainstream laptop CPUs made after 2018 have at least two processor cores, often four cores, and sometimes more, with 8 cores becoming more common.

There has been a wide range of CPUs designed for laptops available from both Intel, AMD, and other manufacturers. On non-x86 architectures, Motorola and IBM produced the chips for the former PowerPC-based Apple laptops (iBook and PowerBook). Between around 2000 to 2014, most full-size laptops had socketed, replaceable CPUs; on thinner models, the CPU was soldered on the motherboard and was not replaceable or upgradable without replacing the motherboard. Since 2015, Intel has not offered new laptop CPU models with pins to be interchangeable, preferring ball grid array chip packages which have to be soldered;

In the past, some laptops have used a desktop processor instead of the laptop version and have had high-performance gains at the cost of greater weight, heat, and limited battery life; this is not unknown as of 2022, but since around 2010, the practice has been restricted to small-volume gaming models. Laptop CPUs are rarely able to be overclocked; most use locked processors. Even on gaming models where unlocked processors are available, the cooling system in most laptops is often very close to its limits and there is rarely headroom for an overclocking–related operating temperature increase.

On most laptops, the GPU is integrated into the CPU to conserve power and space. This was introduced by Intel with the Core i-series of mobile processors in 2010, followed by similar AMD APU processors in January 2011.

Before that, lower-end machines tended to use graphics processors integrated into the system chipset, while higher-end machines had a separate graphics processor. In the past, laptops lacking a separate graphics processor were limited in their utility for gaming and professional applications involving 3D graphics, but the capabilities of CPU-integrated graphics have converged with the low-end of dedicated graphics processors since the mid-2010s. For laptops posessing limited onboard graphics capability but sufficient I/O throughput, an external GPU (eGPU) can provide additional graphics power at the cost of physical space and portability.

Traditionally, the system RAM on laptops (as well as on desktop computers) was physically separate from the graphics memory used by the GPU. Apple"s M series SoCs feature a unified pool of memory for both the system and the GPU; this approach can produce substantial efficiency gains for some applications but comes at the cost of eGPU support.

When upgradeable, memory slots are sometimes accessible from the bottom of the laptop for ease of upgrading; in other cases, accessing them requires significant disassembly. Most laptops have two memory slots, although some will have only one, either for cost savings or because some amount of memory is soldered. Some high-end models have four slots; these are usually mobile engineering workstations, although a few high-end models intended for gaming do as well.

Between 1990 and 2009, almost all laptops typically had a hard disk drive (HDD) for storage; since then, solid-state drives (SSD) have gradually come to supplant hard drives in all but some inexpensive consumer models. Solid-state drives are faster and more power-efficient, as well as eliminating the hazard of drive and data corruption caused by a laptop"s physical impacts, as they use no mechanical parts such as a rotational platter.terabyte) drives have converged; larger capacity drives remain more expensive than comparable-sized HDDs.

Since around 1990, where a hard drive is present it will typically be a 2.5-inch drive; some very compact laptops support even smaller 1.8-inch HDDs, and a very small number used 1" Microdrives. Some SSDs are built to match the size/shape of a laptop hard drive, but increasingly they have been replaced with smaller mSATA or M.2 cards. SSDs using the newer and much faster NVM Express standard for connecting are only available as cards.

As of 2022, many laptops no longer contain space for a 2.5" drive, accepting only M.2 cards; a few of the smallest have storage soldered to the motherboard. For those that can, they can typically contain a single 2.5-inch drive, but a small number of laptops with a screen wider than 15 inches can house two drives.

A variety of external HDDs or NAS data storage servers with support of RAID technology can be attached to virtually any laptop over such interfaces as USB, FireWire, eSATA, or Thunderbolt, or over a wired or wireless network to further increase space for the storage of data. Many laptops also incorporate a SD or microSD card slot. This enables users to download digital pictures from an SD card onto a laptop, thus enabling them to delete the SD card"s contents to free up space for taking new pictures.

Optical disc drives capable of playing CD-ROMs, compact discs (CD), DVDs, and in some cases, Blu-ray discs (BD), were nearly universal on full-sized models between the mid-1990s and the early 2010s. As of 2021, drives are uncommon in compact or premium laptops; they remain available in some bulkier models, but the trend towards thinner and lighter machines is gradually eliminating these drives and players – when needed they can be connected via USB instead.

Interfaces on a ThinkPad laptop (2011): Ethernet network port (center), VGA (left), DisplayPort (top right) and USB 2.0 (bottom right). Due to the trend towards very flat laptops and the widespread use of WLAN, the relatively high Ethernet socket is no longer mandatory in today"s devices, as is the technically outdated VGA.

An alphanumeric keyboard is used to enter text, data, and other commands (e.g., function keys). A touchpad (also called a trackpad), a pointing stick, or both, are used to control the position of the cursor on the screen, and an integrated keyboard

An external keyboard and mouse may be connected using a USB port or wirelessly, via Bluetooth or similar technology. Some laptops have multitouch touchscreen displays, either available as an option or standard. Most laptops have webcams and microphones, which can be used to communicate with other people with both moving images and sound, via web conferencing or video-calling software.

Laptops typically have USB ports and a combined headphone/microphone jack, for use with headphones, a combined headset, or an external mic. Many laptops have a card reader for reading digital camera SD cards.

On a typical laptop there are several USB ports; if they use only the older USB connectors instead of USB-C, they will typically have an external monitor port (VGA, DVI, HDMI or Mini DisplayPort or occasionally more than one), an audio in/out port (often in form of a single socket) is common. It is possible to connect up to three external displays to a 2014-era laptop via a single Mini DisplayPort, using multi-stream transport technology.

Apple, in a 2015 version of its MacBook, transitioned from a number of different I/O ports to a single USB-C port.aftermarket adapters. Apple has since transitioned back to using a number of different ports. Google, with its updated version of Chromebook Pixel, shows a similar transition trend towards USB-C, although keeping older USB Type-A ports for a better compatibility with older devices.Ethernet network port are rarely found on modern laptops, due to widespread use of wireless networking, such as Wi-Fi. Legacy ports such as a PS/2 keyboard/mouse port, serial port, parallel port, or FireWire are provided on some models, but they are increasingly rare. On Apple"s systems, and on a handful of other laptops, there are also Thunderbolt ports, but Thunderbolt 3 uses USB-C. Laptops typically have a headphone jack, so t
