Manufacturers are all over the place when it comes to OLED price premiums; the price bump can range from $150 on an Alienware m15 or HP Spectre x360 to about $700 on a Dell XPS 15; that"s because an OLED display sometimes only comes on a slightly higher configuration, so you end up paying more than you otherwise would have. And while some are only available on the higher-end models, like Razer"s GeForce RTX 2080- or Quadro RTX 5000-equipped Blades, you can get OLED on Lenovo"s  GTX 1650-based ThinkPad X1 Extreme and the Gigabyte Aero 15 with a GTX 1660 Ti.

So sometimes it"s a low enough amount that it inspires serious consideration, but can also be high enough that it"s not a no-brainer. And 15-inch OLED models are a lot more common now than they were when 13-inchers like the

The TL;DR: If the extra bucks are within your budget, then OLED"s high contrast can make working easier on your eyes, especially if you"re in bright environments. And the saturated colors are definitely pleasing to look at. But if the model you want only has an OLED option that will require spending more than you"d like just for higher contrast and brighter colors, for creative work, or specifically to watch

And because an OLED pixel can be completely off, it can produce effectively perfect blacks, and a glowing pixel next to a black one bleeds less light, which would make the black look lighter. That means you get higher contrast. With a backlight, at best you can turn off zones of LEDs to get better blacks and control light bleed -- a technology called

Varying the backlight also increases the time it takes to change a pixel"s brightness, and the bigger the difference between the brightness of side-by-side pixels, the longer it takes. That lag, called "response time" is important for gaming, where pixel states need to change as fast as possible to prevent blurring where you don"t want it.

OLED"s response time is as close to instantaneous as you can get with current technologies, though it"s still subject to moving picture response time blur. To get even closer with an LCD you have to use TN (twisted nematic), which otherwise is a real drop in quality over other options, such as the more common IPS (in-plane switching).

A laptop faces some significant drawbacks that a TV or phone doesn"t. Such as:Battery life:Since it can individually control pixel brightness values, OLED is more power efficient overall than LCD for mixed content. But for a mostly white screen, like when you"re shopping on white-background Amazon or working in white-background background Google docs, firing up all those OLED pixels to a comparable brightness takes a lot more power. It does make them easier on the eyes, though, despite the battery life hit.

Windows: TVs and phones don"t have to run Windows, either. Their displays are tightly integrated with the software and the best ones are factory calibrated with selectable color profiles. Microsoft doesn"t require custom color profiles for monitors, and most end up with the Generic PnP profile, which makes assumptions that don"t necessarily apply to OLED. So no matter how accurate the screen is -- and OLED can be very, very accurate -- if a video says to the graphics subsystem "give me a saturated red," the default profile shouts back, "You want red? I"LL SHOW YOU RED!!!" It doesn"t know how to optimally map the broader range of colors properly or how to not crush all the detail in the dark shadows.

Gaming: While OLED has a fast response time, the screens only come in 4K, so you run into a fixed 60Hz refresh-rate limit; 4K laptop displays have just starting reaching refresh rates of 120Hz, but none in OLED. Depending upon the games you play, ugly frame-rate sync artifacts like tearing and stutter may overshadow the OLED"s pleasing pop and fast pixel response times. RTX 2080-based systems are fast, but not fast enough for consistent 60fps 4K gameplay, And if you drop to a lower resolution for better frame rates, you"ll need to use software-based vsync or cap the frame rate to get best results.

On one hand, OLED displays have a native wide-color gamut that covers 100% of the Apple-popularized P3 color space, necessary for decent HDR viewing and currently the de facto broadest color coverage generally available. But that"s only one piece of the HDR equation, which also includes:Luminance -- how bright the screen or at least a small portion of the screen can physically get as well as how bright it can get with power management settings

display drivers and color management -- these inform the operating system about the capabilities of the screen and how to best map the colors of the content to the screen, along with the internal metadata stored in the display

DRM and IP -- digital rights management and business-model driven intellectual property protections define what you can or can"t stream in 4K and/or HDR, and not all DRM schemes are supported by Windows and vice versa

Viewing HDR content and playing games in HDR on your laptop requires that all those pieces fit together seamlessly. Under Windows, that means it takes some fiddling at best and defies solution at worst -- and not just for OLED. But in a laptop, OLED screens can"t get very bright: The maximum I"ve measured has been just under 600 nits (the rated peak the panel is capable of), but most are under 500 nits; that"s notably lower than OLED TVs.

Furthermore, given the variables listed above, simply using OLED technology isn"t a sufficient condition for HDR support; at the very least, the manufacturer also has to flag to DirectX that it supports the necessary basic tone-mapping algorithm (HDR10). Without that, you don"t get the Windows HDR options in the Display settings.

The only manufacturer of OLED laptop panels is Samsung, and it only makes one panel at the moment. There"s some variation across the executions, though not as much as I expected. Unsurprisingly, all displays cover the same gamut: over 100% of

While Samsung"s panel is technically capable of reaching a maximum brightness of 600 nits, that doesn"t mean the manufacturer has to drive it that high -- that"s one of the ways executions can vary. For full-screen use -- you know, when you"re doing laptoppy things -- they all settle around in the 380-400 nit range. But at 70% brightness, which I consider a good working level, it"s closer to 200-230. While that"s the same as newer LCD screens, that brightness looks a lot better on OLED because of the contrast.

Though not as robust as the color management of a mobile workstation, which generally has profiles stored in hardware, it"s one of the broader systems I"ve seen in a prosumer laptop. For example, it comes with a Pantone-certified software profile for print work, plus four color temperature software-calibration profiles (D5800, D6000, D6500 and D6800), which you can swap among via the ControlCenter rather than using Windows" system. Oddly, the Native profile it loads is sRGB rather than just a full-monitor gamut, which is what "native" usually means in this context.

As tested (using Portrait Displays" Calman 5 Ultimate and an X-Rite i1Display Pro), the display is very accurate for a nonpro screen. It covers 100% of DCI-P3 and about 93% of the Adobe RGB color gamuts, all the white points come within 250K of their targets, gamma is very consistently close to 2.2 above 20% gray (OLED gamma has a discontinuity roughly below 20% because it has different shadow-detail characteristics than monitors with less perfect blacks, for which a gamma of 2.2 became standard) and the gray scale is reasonably neutral. For colors, it"s very accurate at maximum brightness -- I was told it was calibrated to 100% brightness for Adobe RGB and it might be even better at lower brightness levels -- and with just a little tweaking could probably hit anyone"s accuracy threshold.

It hit a peak brightness of over 600 nits for a 10% window in HDR mode, though most often that will be closer to about 415 nits, and full-screen maximum brightness for normal work is around 350 nits.

The Asus" OLED screen is Pantone Validated  -- it comes with two undocumented software profiles -- and uses the same Samsung panel as all the current models. It"s slightly dimmer than the others at a peak full-screen brightness of about 356 nits, but offers the same full P3 gamut coverage -- only 93% of Adobe RGB, though. (It"s listed as DisplayHDR 500 True Black compliant, so I"m not entirely confident of my peak brightness result of 416 nits for a 10% window. Consider my results a work in progress.) I think it uses the same touch overlay as the HP Spectre x360, because it has the same grainy look up close, and like that system it supports Windows HDR for everything. Asus" recommended brightness when working on battery is 40%, which is definitely too dim.

I think some of the differences in the HP"s screen performance -- slightly less bright with a warmer white point than the other two -- stem from the antiglare coating. The screen also has a visible dither-like pattern on white, which appears on other models, but is a little more pronounced on this model. And viewed from the side, the coating also produces faint rainbows.

But that coating makes looking at the screen a lot more pleasant than the mirror-like surface of the Razer. The battery life is also relatively good (for a 4K laptop), lasting 8.6 hours. Our tests don"t use a lot of white screens, however.

The opportunity to watch videos side-by-side on the OLED and non-OLED HPs was educational: I learned the non-OLED display was a lot better than I thought. Standard definition video looked more saturated and contrasty on the OLED, but it also crushed the blacks and pushed reds to a disturbing degree. Skin tones were not great.

Though the laptop supports HDR for games, the MX150 can"t really run any games that support HDR. (Though HDR by itself shouldn"t impact performance, it usually comes with some other visual baggage that does.) But the dark blacks and bright colors pep up any game, as long as you don"t need to search the shadows.

The Blade also comes with a touchscreen version of the OLED display, which is novel for a gaming system (though more common than it used to be). While it pushed the brightness higher than the other laptops, it also had an odd gamma curve that reminded me of film"s with a knee and a shoulder, as if it"s intended to bring out more detail in the highlights, but less in the shadows.

That, and the high brightness, is probably why it doesn"t result in as compressed a tonal range as the HP in HDR mode when you"re not viewing HDR content. Still, though, I had trouble getting any HDR with really bright zones to look good. It just doesn"t map gracefully to the lower brightness.

Plus, it was kind of hard to see the shadows or appreciate the blacks, because the screen is so reflective. I couldn"t find an angle where I wasn"t staring at the overhead lights or myself (even in the dark).

However, the Razer also seemed to get "stuck" halfway between HDR and SDR modes when switching back and forth, in that HDR video would occasionally look like it was crushed into the smaller SDR space -- low brightness, desaturated colors and whites clipped to gray.

Games, of course, look great. But the lights in HDR mode that look searing in Hellblade: Senua"s Sacrifice on a 1,000-nit display, didn"t sear quite as much.

I tested the OLED display for the m15 on an old model before the latest generation design was available. You can read my impressions about it, but because so much of the display"s performance depends on implementation, I don"t consider those final.

The model of the XPS 15 I tested delivered good general-purpose performance -- it wasn"t terribly color accurate and only came with a single general color profile, but Dell tends to reserve its color-accurate options for its professional Precision models. For full-screen (i.e., everyday) work, it gets decently bright at around 400 nits.

Just like televisions, laptop displays start to flicker too after a few years. You may sometimes also notice the display turning blank even when the laptop is on. Alternatively, you might find some white lines running down the display.

This doesn’t necessarily mean that there is an issue with the motherboard. If your laptop keeps turning off every few minutes and doesn’t turn on, there is a high chance that the AC adapter has malfunctioned. You can get help from a professional to confirm and get the AC adapter replaced, if required. There is also a possibility that the DC power jack may have broken. A DC connector (or DC plug) is an electrical connector that supplies steady power to the device.

If the DC jack has broken, you can try adjusting the plug’s angle in its jack. If you see some lights turning on but the device is still not booting, it’s time to replace the DC jack. If that doesn’t help, it’s a clear indication of a motherboard-related issue. You can either get the motherboard repaired or replaced by the brand service center. Getting the motherboard repaired could cost you anywhere up to Rs 10,000, whereas the cost of replacing the motherboard can go anywhere up to Rs 25,000.

If you ever notice multi-coloured or single-coloured vertical lines on your laptop screen, it may be a result of a hardware failure or due to damage to the screen. To try fixing it yourself, first unplug your laptop, hold the power button for 30 seconds and restart the laptop. If you continue to see coloured lines, the issue is probably with the LCD screen, which will need to be replaced from the brand’s service center. To be sure about the LCD screen problem, try connecting your laptop to another monitor and see if the issue persists. If it does, the issue is certainly in the LCD panel.

On turning on the laptop when you see the lights blinking and hear the fan working but if the laptop screen is blank and doesn’t display anything, this is again an indication of a faulty motherboard. The first thing to do is to transfer all the data to another drive to make sure your data is safe. Before going ahead and getting the motherboard repaired or replaced, you could try performing a hard reset (also known as a factory reset), which can mostly help in resolving the blank display issue.

Firstly, check if your laptop’s brightness level is set to maximum. If the display is still dim, try restarting the device. This could just be a system error that can be resolved by restarting the device. Also, check if the AC adapter cord is loose and firmly connect it to the outlet and laptop. If the issue still persists, it is mostly due to a failure of the LCD. Behind the LCD, there is an inverter board and backlight bulb which control the picture.

The inverter board converts the low voltage your laptop uses, into higher voltage required by the long bulb that lights up the LCD screen. If the inverter board or bulb fail, you will experience the problem of a dimmed display. Even if one of these two components fail, the screen will need to be replaced, unless the service center can help by just replacing the bulb. We wouldn’t recommend you try resolving it yourself, as this is more complex and you could end up damaging the circuit board and the backlight lamp. So, it’s best to leave this job to an expert.

Laptops are fragile and can easily break, especially with more and more thinner and lighter models being launched now. Some of the most common ways how a laptop is damaged include: when it accidentally falls and the screen cracks, when it’s held at an awkward angle or if you unknowingly placed something heavy on the laptop. Remember, a cracked laptop screen can affect the overall functioning of the device in some cases.

Since brands do not cover the laptop screen, it’s best to get your device covered with a protection plan in advance. Screen replacements are expensive and can cost you anywhere up to Rs. 15,000 but if you have the

Laptops were created to imitate the full functionality of a desktop unit with the addition of portability. Notebook computers were meant to be light and provide "bare bones" laptop functionality. Initially, hard drive capacity and RAM were usually much higher in laptops, and many offered CD/DVD drives that matched those found in desktop units. However, as chip sets and hardware capabilities have expanded, the differences between a laptop and a notebook computer have blurred, both in size and functionality.

Laptops were originally marketed as "business" machines, capable of using spreadsheet, presentation, and financial software packages, just as desktops could. Notebooks were mainly marketed for "personal" tasks, such as email, writing, entertainment, and file management. The biggest difference between the two eventually became the size and weight of the battery, with laptops boasting 2-3 times the battery life of notebooks, but also weighing 3-5 pounds more.

As hardware capabilities increased, laptops became powerful enough to become primary computers for many people. Despite being more expensive than desktop units, the computer had become a personal device used for much more than office or schoolwork, so portability was a key feature. The growth of smartphone and tablet use also reduced the need and usability of a desktop unit, as well as the need for a large laptop. Notebooks also started featuring high-resolution screens, while the need for DVD drives was reduced as broadband Wi-Fi and streaming through services like Netflix and Spotify became ubiquitous.

In 2007, laptop sales declined for the first time since 1998, while notebook sales rose. Even so, the rise of tablet computers slowed notebook sales in 2010. What has emerged from this proliferation of portable computing devices is a nuanced market, with laptops occupying the high-end user niche (graphic artists, executives, freelancers), notebooks used primarily by students and highly-mobile workers, and tablets used widely by the general public.

A big advantage of laptops is that they can be configured in many ways for different tasks and needs. For example, a common laptop configuration for playing games includes expanding RAM, adding a high-end graphics and video card, and "overclocking" (removing limitations) on the hardware to allow for faster response times.

The typical laptop nowadays has a 1 terabyte (TB) drive or a solid state drive (SSD), the latter of which is hundreds of times faster than hard drives were 10 years ago. RAM capacity is often 4-12 GB, screens feature large HD resolutions (and sometimes retinal displays), and battery life is about 6-10 hours. Many laptops are large enough to offer a full keyboard, are usually about 13-18 inches wide, and weigh 4-8 lbs. on average.

Notebook computers are less likely to offer a full-sized keyboard, ranging from 8.5 to 12.5 inches. The average notebook offers about 512 GB on the hard drive, with some models now offering an SSD option of up to 1 TB. RAM is usually 2-4 GB, and screen quality can vary. Two major differences between current laptops and notebooks are found in battery life and weight: notebooks tend to have a much longer battery life (ranging from 5 to 14 hours) typically weigh in at under 5 lbs.

There is a hybrid niche of extremely lightweight portable computers that feature full-sized keyboards, but below-average hardware capabilities. An example from this category would be the MacBook Air, which has a 13.5-inch screen and a full-sized keyboard, while weighing less than 3 pounds. The battery life is rated at 7 hours, but depending on use, it can extend up to 13 hours. The basic MacBook Air does not offer ports for connecting other devices, has a limited 360 GB hard drive, and has no DVD drive.

Prices for new laptop computers vary widely depending on screen size and hardware configurations. Low-end laptops tend to go for under $500, while high-end laptops used for advanced work-related tasks or gaming can easily exceed $1,000. Apple"s Mac laptops will generally be more expensive than comparable PC laptops.

In 1976, the Xerox PARC division developed the Xerox NoteTaker, considered the first portable computer. It never reached the market, as only 10 prototypes were built. In 1981, the Osborne 1 was launched as the first commercially available portable computer. About the size of a tabletop sewing machine, the Osborne did not have any battery power, running only on electricity instead, but it allowed computer users to work with a computer while on the go.

In the span of barely 3 years, portable computer models started flooding the market. In 1982, Kaypro introduced the Kaypro II, which featured double-sided floppy drives (twice the storage capacity) and a larger CRT monitor. The first true laptop, the GRiD Compass 1101, was arguably released that same year. In 1983, Compaq launched its Compaq Portable, while Epson introduced the HX-20.

By 1988, portable computers had become smaller, as demonstrated by the Cambridge Z88. Though this portable computer was 16 times more powerful than the Osborne 1, its total weight had been halved.

The first "notebook computers" — so called because the size of these devices was roughly the size of a paper notebook — were the 1988 NEC UltraLite and the Compaq LTE, launched in 1989. These designs were then joined by the IBM ThinkPad, featuring the first 10.4 inch screen on a notebook computer. While these early notebooks averaged a little over 6 pounds, lighter and more powerful "sub-notebooks" began making their mark in 1993 with the introduction of the Gateway Handbook and the Hewlett-Packard OmniBook. The 4.4 pound Apple PowerBook was eclipsed by the Sony VAIO in 1997, the latter weighing in at under 2.5 pounds. Microsoft"s Tablet PC computers were smaller still, and in 2007, Asus introduced the Eee PC, reducing screen and keyboard size while retaining full computer usage capabilities.

Both laptop and notebook sales have declined as the sale of smartphones and tablets have risen. However, outside the U.S., notebook computers are showing a slight increase in sales as these units combine lower cost and broad functionality that can best address infrastructures in the midst of growth, such as in South America and Africa.

It seems counter-intuitive that a 120 Hz / 0.2 ms OLED display could outperform a 165 Hz / 3 ms LCD display rival — so how is this possible? Well, the LCD panel takes precisely 6.06 ms to refresh each frame, but it takes another 3 ms of response time to process the correct colors. That’s a total of 9.06 ms to fully load the image. A 144 Hz / 12.5 ms LCD display takes even longer, at 19.44 ms to show the full, final frame of each image. But with its extreme-speed response, a 120 Hz / 0.2 ms OLED display takes just 8.5 ms to process the same — making it even faster than a 165 Hz / 3 ms LCD display.
