While the SDM-HS73 does not offer any distinct technological advantages over other LCD displays in the $500 dollar price range, the design is unique enough to offer something a little different. The overall display properties and color presentation were slightly above average throughout our testing although not outstanding. The SDM-HS73 would look great in any office or home setting and is sure to be the center of attention for some time to come. If you are in the market for a new LCD monitor and would like something to match your modern décor, the SDM-HS73 is sure to be the perfect match. The SDM-HS73 can be found for $499 through online retailers and comes in two colors, black and silver.

If you have been watching the LCD market for a few months, then you probably have noticed a lot of changes. First of all, prices are dropping at rapid rates and secondly there are more LCD models to choose from than ever before. The SDM-HS73 from Sony is just one of a number of LCD displays available for around $500 dollars. What sets the SDM-HS73 apart from the rest of the LCD’s in this price range is the infamous Sony Style design which makes the SDM-HS73 great to look at in any room of the house.

Most if not all LCD monitors in the sub $500 price range have a few things in common when it comes to their specifications. First, you will be hard pressed to find a 17″ LCD with a pixel refresh rate higher than 60HZ, and secondly almost none of the monitors will feature a DVI input. The SDM-HS73 lives up to this trend with no DVI, USB inputs and no internal speakers.

At first glance the SDM-HS73 actually appears to be larger than the 17″ size the screen really is. This is because of the extra molding width located on each of the sides. The main display sits on top of a bowed arm and gives the effect of floating above the base stand. The curvilinear arm is attached to the thin disc base where the tilt of the whole display can be adjusted. As with most other LCD monitors there is no height adjustment or swivel capabilities.

The controls are located on the bottom of the main display and feature a picture legend to direct you to the correct controls. While the control location and design are not uniform to other LCD displays, we found them to work fine and quickly became accustomed to their location after minimal use. The overall location of the display controls help to augment the display’s design

Image quality on the SDM-HS73 is average and certainly within our expectations for a monitor in this price range. The built in auto-sync feature worked flawlessly while the brightness and contrast levels did an adequate job. There was no apparent white-out from any screen location. Sometimes, with other LCD monitors, you can see where parts of the screen are brighter than others, but this was not the case with the SDM-HS73. The SDM-HS73 looked good from multiple viewing angles up to about 45 degrees and the gray-level response was excellent requiring no adjustments to the default settings.

The SDM-HS73 employs a removable back cover to help conceal the monitor cables. The cover simply plugs into 4 holes located in the adjacent corners and looks aesthetically pleasing while in place. Because of the curvilinear arm being located just under the display, the cables are not visible from the front.

For our gaming tests the SDM-HS73 performed admirably in overhead and 2D gaming. If you are a hardcore gamer and prefer 3D first person shooters, you are better off sticking with a traditional CRT monitor or a larger LCD display with a higher pixel refresh rate. As far as ghosting and trailing are concerned, the SDM-HS73 faired better than most early model LCD monitors. We found that ghosting and trailing depended on the game. While playing Warcraft 3 for example, we experienced no ghosting or trailing whatsoever and preferred playing Warcraft 3 on the LCD monitor due to the fantastic contrast and brightness levels. Playing a First Person Shooter called Tactical Operations, there was no apparent ghosting, but there was minimal trailing. It just did not feel right playing a First Person Shooter on this monitor.

While the SDM-HS73 does not offer any distinct technological advantages over other LCD displays in the $500 dollar price range, the design is unique enough to offer something a little different. The overall display properties and color presentation were slightly above average throughout our testing although not outstanding. The SDM-HS73 would look great in any office or home setting and is sure to be the center of attention for some time to come.

This 3.5" EVE TFT bundle has everything you need to get started with this powerful display. The development kit consists of a 3.5" display mounted on an EVE2 graphically accelerated PCA, a Seeeduino, an EVE breakout board, jumper wires, USB cable and 6-inch ribbon cable.

With a resistive touch screen, full color, and a 6 o"clock viewing angle the display is a great way to offer a full user experience. For more information about the display, including its detailed datasheet, check out the 320x240 3.5" Touch Screen Color TFT page.

The EVE chip really makes this TFT module really shine. EVE (embedded video engine) is a cool new technology from FTDI/Bridgetek that simplifies the process of displaying videos and text in an embedded project. All display, touch sensing, backlight, and audio features are controlled by the FTDI FT810 EVE which appears to host the MCU as a memory-mapped SPI device. The host MCU sends commands and data over the SPI protocol. The module can support both SPI and Quad-SPI.

Outlined in this section are TFT LCD (Thin Film Transistor Liquid Crystal Display) basic knowledge, including structures, driving methods (Passive Matrix / PMLCD, Active Matrix / AMLCD) and comparison, RGB filters, display mode, generations and production process.

As our society progresses into an overwhelmingly technological state, screens seem to pop up almost everywhere. Behind those glass displays, or flat panel displays, lie hundreds of thousands of complex, tiny devices, controlling the pixels that comprise the overall image we see. Those devices are known as Thin Film Transistors, or abbreviated, TFTs.

A TFT LCD,  or a thin film transistor liquid crystal display, is one of the fastest growing forms of display technology today. The thin film transistor (TFT) is a type of semiconductor device used in display technology to enhance efficiency, compactness, and cost of the product.

LCD has a genetic disadvantage compared to other display technologies: Narrow Viewing Angles.  For the last 40 years, scientists and engineers put a lot of effort to improve LCD viewing angles and made great progress. In this section we will introduce O-Film TFT, MVA (Multi-domain Vertical Alignment) TFT, IPS (In Plane Switching)and AFFS (Advanced Fringe Field Switching) TFT.

Most of TFT LCDs are hard to read under the sunlight. Orient Display offer Sunlight Readable TFT with these approaches: Transflective TFT, Surface Treatment, Optical Bonding.

Orient Display’s Electro-Optical Characteristics contains sections of Optical Measurement System, Viewing Angle Range & Measurement System, Contrast Ratio and Response Time.

Over time, the image quality on your computer monitor can start to look a little lackluster or even too bright. Before you consider upgrading your entire system or getting a new monitor, there might be a much simpler, quicker, and economical solution — calibrate your monitor.

You could take your monitor to a professional to have it done, but doing it yourself is relatively quick and hassle-free and will greatly improve image quality. Manufacturers keep pumping out displays with new technologies like 4K UHD resolution, high dynamic range (HDR), and curved monitors, providing a veritable feast for the eyes — but only if they are properly calibrated.

Step 3: Make sure you’re calibrating in a room with moderate ambient lighting. The room doesn’t need to be pitch black, but you don’t want the sharp glares and color casts resulting from direct light.

Step 4: Familiarize yourself with your monitor’s display controls. They may be located on the monitor itself, on the keyboard, or within the operating system control panel.

Both MacOS and Windows have built-in calibration tools to help guide you step-by-step through the process, which is particularly helpful if you are new to monitor calibration. These free tools should be the first stop if you’re merely a casual image junkie or working on a tight budget. Keep in mind that the adjustments will be limited by the display type and model, though.

In older versions of Windows, you can find the Color Calibration utility in the Display section of the Control Panel, which is listed under Appearance and Personalization.

Step 2: Now that you are in the calibration tool, follow the on-screen instructions to choose your display’s gamma, brightness, contrast, and color balance settings.

Step 3: Once the calibration wizard is complete, make sure to choose the Current calibration, or return to the previous calibration if you are unsatisfied with the results. The new calibration will be stored as an .ics file, or color calibration file, and will show up as a new International Color Consortium (ICC) Profile in the Color Management settings app.

Step 4: The easiest way to open this app is to type "color management" in the search box and choose the first result. Once it’s open, you can select your monitor from the device list and see which ICC Profiles are available.

Step 1: In MacOS, the Display Calibrator Assistant is located in the system preferences under the Displays tab, in the Color section. If you are having trouble finding it, try entering calibrate in Spotlight to scan through your computer’s various folders and files. The results should show an option to open the utility in the System Preferences panel.

Color adjustments: White point is a given, but Apple will try to detect your display and offer a number of other color calibrations at this point … or it may skip the rest of the adjustment options entirely. Native Apple displays may be more likely to have fewer color calibrations at this point (because Apple already calibrated them).

Step 3: This will create a new color profile for your display. If you couldn’t make the adjustments that you wanted to, then select this new profile and choose Open Profile. This will open a new window with all the tags associated with the color profile and their descriptions.

Step 4: You can choose each tag to see more information about them. Some tags will just be basic color data, but other tags can be altered to change specific color factors for the display.

Step 5: If you have a native display, look for the Apple display native information tag as a good place to start. As you can see, this can quickly become technical, so you will need to know your color data (phosphor values, response curves, etc.) to make accurate changes with this method.

W4zt Screen Color Test: This simple webpage provides you with several color gradients and grayscale color boxes you can use for quick comparisons, along with an easy gamma test you can run. It’s nice to have so many tests on one page, making this solution great for fast and dirty calibration so you can move on.

The Lagom LCD Monitor Test Pages: Handy for both online and offline use, the Lagom LCD Monitor Test Pages not only allow you to adjust various things such as contrast and response time, but also allow you to download the images as a 120KB zip file, so you can check any monitor in-store that you are thinking about purchasing.

Calibrize 2.0: If you want a great tool that goes a little more in-depth than native calibration options, we suggest downloading Calibrize 2.0. It’s an excellent free wizard that carefully walks you through well-explained steps to help you calibrate color, grayscale, gamma, and similar settings on your computer.

While they’re better than a more temporary solution, built-in calibration utilities still have one major flaw: You. Since they rely on your specific color perception, what looks great to you might look thoroughly off to a friend.

The best way to avoid this problem and ensure that you calibrate your monitor correctly is by purchasing a calibrating device. You’ll need to spend a decent amount of money for the best control and precision. Still, there are affordable alternatives to help you achieve consistent color across all of your monitors.

If you’re looking for a calibration tool, we recommend either the X-Rite ColorMunki Smile ($99) or the Spyder5Elite ($200). Both devices boast a full-spectrum, seven-color sensor that can accurately display a range of standard and wide-gamut displays. If you have a bigger budget, you can look for upscale calibrators that have even more advanced options.

Starting at $180, X-Rite’s i1Display is another solid device. Just like the Spyder series, each of these three options is configured with automated calibration software. The more money you spend, the more additional features and other benefits you’ll get from the device.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

The next example is controlling an RGB LED using these three RGB sliders. For example if we start to slide the blue slider, the LED will light up in blue and increase the light as we would go to the maximum value. So the sliders can move from 0 to 255 and with their combination we can set any color to the RGB LED,  but just keep in mind that the LED cannot represent the colors that much accurate.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

Well, I really want to like it. One thing I can definitely say for it is that the resolution and clarity of the screen is excellent. Oddly, the color/brightness settings are weird though. To get it about where an decent screen should be, I had to set brightness all the way down to 33 and both contrast and saturation had to actually go way up to 75 or so. (I don"t really have a calibration guide handy, so this was eyeballing it.) Note that this has no backlight adjustment -- this is a software brightness setting that barely changes it by a lot (so mostly a higher setting just washes things out.) Contrast almost seems to adjust sharpness more than actual contrast as well, which is strange, so it needs to be higher but does worse if you go too high. When you set things connected to it to produce 1024x600 resolution the clarity with these settings is beyond amazing for such a tiny screen though. Even at a HDMI default of 720p it"s actually pretty good. It also seems to be _VERY_ tolerant of outside resolutions. I accidentally typed 1024x700 and it took me a while to figure out what was wrong because it not only accepted the resolution, but resized it very well and it was still very clear. That"s a pretty huge plus right there and would have been worthy of at least four stars. If it wasn"t for the viewing angle...

Unfortunately, this is where it loses significant points. If I were rating it on viewing angle alone it would get one star even. I"ve never seen a screen this bad in that respect and I have used laptops in the MS-DOS days when LCD latencies were practically measured in seconds rather than milliseconds (pro-tip, NEVER play Descent on a laptop with really really high LCD latency. You WILL be sick.) Left and right viewing angle are great -- which is ironic because in most applications for this thing left and right aren"t that big of an issue -- but the up and down viewing angle literally couldn"t be any worse. Specifically, you can NOT look at this thing directly straight on. It MUST tilt up away from you so you"re basically looking up at it somewhat. I would estimate it has to go about 25-30 degrees or so off from being parallel. That"s pretty extreme to the point of being a bit ridiculous. The stand doesn"t do high precision either on the tilt, so you won"t really get it at quite an optimal angle and just have to get it as close as you can (about 35 or so I guess is what it works out to if you get it on the closest catch and then tilt it just a bit.) If you get at all close to looking at it parallel it turns insanely dark and you can"t see details or color well at all -- even text is insanely hard to read. As you approach 90 degrees, it starts to invert before you even actually get to a straight head-on look at it. Any higher and it outright inverts. If you can tilt it just right, the colors are pretty close to an IPS panel almost even (a bit lacking compared to a real IPS, but better than most TFT panels.) But this unreasonable viewing angle is extremely offputting. Also, as a side effect, since it has to stay tilted upwards, this means it collects dust like there is no tomorrow. That"s even more offputting. If it didn"t have such good visual clarity and color production I"d have to give it only one star even. Unfortunately, no matter how you position it, it will never be QUITE right with colors a bit more washed than they should be at one angle and too dark to even see at another. If you"re buying this just to act as a camera monitor or a simple screen for a server or something it will work great, but if you buy it for handling something like an OpenElec system, you"ll probably be very unhappy with the ridiculous viewing angle.

An excellent new compatible library is available which can render TrueType fonts on a TFT screen (or into a sprite). This has been developed by takkaO and is available here. I have been reluctant to support yet another font format but this is an amazing library which is very easy to use. It provides access to compact font files, with fully scaleable anti-aliased glyphs. Left, middle and right justified text can also be printed to the screen. I have added TFT_eSPI specific examples to the OpenFontRender library and tested on RP2040 and ESP32 processors, however the ESP8266 does not have sufficient RAM. Here is a demo screen where a single 12kbyte font file binary was used to render fully anti-aliased glyphs of gradually increasing size on a 320x480 TFT screen:

For ESP32 ONLY, the TFT configuration (user setup) can now be included inside an Arduino IDE sketch providing the instructions in the example Generic->Sketch_with_tft_setup are followed. See ReadMe tab in that sketch for the instructions. If the setup is not in the sketch then the library settings will be used. This means that "per project" configurations are possible without modifying the library setup files. Please note that ALL the other examples in the library will use the library settings unless they are adapted and the "tft_setup.h" header file included. Note: there are issues with this approach, #2007 proposes an alternative method.

Support has been added in v2.4.70 for the RP2040 with 16 bit parallel displays. This has been tested and the screen update performance is very good (4ms to clear 320 x 480 screen with HC8357C). The use of the RP2040 PIO makes it easy to change the write cycle timing for different displays. DMA with 16 bit transfers is also supported.

Smooth fonts can now be rendered direct to the TFT with very little flicker for quickly changing values. This is achieved by a line-by-line and block-by-block update of the glyph area without drawing pixels twice. This is a "breaking" change for some sketches because a new true/false parameter is needed to render the background. The default is false if the parameter is missing, Examples:

New anti-aliased graphics functions to draw lines, wedge shaped lines, circles and rounded rectangles. Examples are included. Examples have also been added to display PNG compressed images (note: requires ~40kbytes RAM).

Frank Boesing has created an extension library for TFT_eSPI that allows a large range of ready-built fonts to be used. Frank"s library (adapted to permit rendering in sprites as well as TFT) can be downloaded here. More than 3300 additional Fonts are available here. The TFT_eSPI_ext library contains examples that demonstrate the use of the fonts.

Users of PowerPoint experienced with running macros may be interested in the pptm sketch generator here, this converts graphics and tables drawn in PowerPoint slides into an Arduino sketch that renders the graphics on a 480x320 TFT. This is based on VB macros created by Kris Kasprzak here.

The RP2040 8 bit parallel interface uses the PIO. The PIO now manages the "setWindow" and "block fill" actions, releasing the processor for other tasks when areas of the screen are being filled with a colour. The PIO can optionally be used for SPI interface displays if #define RP2040_PIO_SPI is put in the setup file. Touch screens and pixel read operations are not supported when the PIO interface is used.

DMA can now be used with the Raspberry Pi Pico (RP2040) when used with both 8 bit parallel and 16 bit colour SPI displays. See "Bouncy_Circles" sketch.

The library now supports the Raspberry Pi Pico with both the official Arduino board package and the one provided by Earle Philhower. The setup file "Setup60_RP2040_ILI9341.h" has been used for tests with an ILI9341 display. At the moment only SPI interface displays have been tested. SPI port 0 is the default but SPI port 1 can be specifed in the setup file if those SPI pins are used.

The library now provides a "viewport" capability. See "Viewport_Demo" and "Viewport_graphicstest" examples. When a viewport is defined graphics will only appear within that window. The coordinate datum by default moves to the top left corner of the viewport, but can optionally remain at top left corner of TFT. The GUIslice library will make use of this feature to speed up the rendering of GUI objects (see #769).

An Arduino IDE compatible graphics and fonts library for 32 bit processors. The library is targeted at 32 bit processors, it has been performance optimised for RP2040, STM32, ESP8266 and ESP32 types, other processors may be used but will use the slower generic Arduino interface calls. The library can be loaded using the Arduino IDE"s Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040 and STM32 processors with SPI interface displays to improve rendering performance. DMA with a parallel interface (8 and 16 bit parallel) is only supported with the RP2040.

For other processors only SPI interface displays are supported and the slower Arduino SPI library functions are used by the library. Higher clock speed processors such as used for the Teensy 3.x and 4.x boards will still provide a very good performance with the generic Arduino SPI functions.

"Four wire" SPI and 8 bit parallel interfaces are supported. Due to lack of GPIO pins the 8 bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can used with the STM32 Nucleo 64/144 range or the UNO format ESP32 (see below for ESP32).

The library supports some TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320 pixel screen. The ILI9486 RPi display must be of the Waveshare design and use a 16 bit serial interface based on the 74HC04, 74HC4040 and 2 x 74HC4094 logic chips. Note that due to design variations between these displays not all RPi displays will work with this library, so purchasing a RPi display of these types solely for use with this library is NOT recommended.

A "good" RPi display is the MHS-4.0 inch Display-B type ST7796 which provides good performance. This has a dedicated controller and can be clocked at up to 80MHz with the ESP32 (125MHz with overclocked RP2040, 55MHz with STM32 and 40MHz with ESP8266). The MHS-3.5 inch RPi ILI9486 based display is also supported, however the MHS ILI9341 based display of the same type does NOT work with this library.

Some displays permit the internal TFT screen RAM to be read, a few of the examples use this feature. The TFT_Screen_Capture example allows full screens to be captured and sent to a PC, this is handy to create program documentation.

The library supports Waveshare 2 and 3 colour ePaper displays using full frame buffers. This addition is relatively immature and thus only one example has been provided.

The library includes a "Sprite" class, this enables flicker free updates of complex graphics. Direct writes to the TFT with graphics functions are still available, so existing sketches do not need to be changed.

The "Animated_dial" example shows how dials can be created using a rotated Sprite for the needle. To run this example the TFT interface must support reading from the screen RAM (not all do). The dial rim and scale is a jpeg image, created using a paint program.

The XPT2046 touch screen controller is supported for SPI based displays only. The SPI bus for the touch controller is shared with the TFT and only an additional chip select line is needed. This support will eventually be deprecated when a suitable touch screen library is available.

The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses. Only one SPI device can be connected to the FLASH pins and the chips select for the TFT must be on pin D3 (GPIO0).

Configuration of the library font selections, pins used to interface with the TFT and other features is made by editing the User_Setup.h file in the library folder, or by selecting your own configuration in the "User_Setup_Selet,h" file. Fonts and features can easily be enabled/disabled by commenting out lines.

Anti-aliased (smooth) font files in "vlw" format are generated by the free Processing IDE using a sketch included in the library Tools folder. This sketch with the Processing IDE can be used to generate font files from your computer"s font set or any TrueType (.ttf) font, the font file can include any combination of 16 bit Unicode characters. This means Greek, Japanese and any other UCS-2 glyphs can be used. Character arrays and Strings in UTF-8 format are supported.

It would be possible to compress the vlw font files but the rendering performance to a TFT is still good when storing the font file(s) in SPIFFS, LittleFS or FLASH arrays.

Anti-aliased fonts can also be drawn over a gradient background with a callback to fetch the background colour of each pixel. This pixel colour can be set by the gradient algorithm or by reading back the TFT screen memory (if reading the display is supported).

The common 8 bit "Mcufriend" shields are supported for the STM Nucleo 64/144 boards and ESP32 UNO style board. The STM32 "Blue/Black Pill" boards can also be used with 8 bit parallel displays.

Unfortunately the typical UNO/mcufriend TFT display board maps LCD_RD, LCD_CS and LCD_RST signals to the ESP32 analogue pins 35, 34 and 36 which are input only. To solve this I linked in the 3 spare pins IO15, IO33 and IO32 by adding wires to the bottom of the board as follows:

If the display board is fitted with a resistance based touch screen then this can be used by performing the modifications described here and the fork of the Adafruit library:

If you load a new copy of TFT_eSPI then it will overwrite your setups if they are kept within the TFT_eSPI folder. One way around this is to create a new folder in your Arduino library folder called "TFT_eSPI_Setups". You then place your custom setup.h files in there. After an upgrade simply edit the User_Setup_Select.h file to point to your custom setup file e.g.:

The library was intended to support only TFT displays but using a Sprite as a 1 bit per pixel screen buffer permits support for the Waveshare 2 and 3 colour SPI ePaper displays. This addition to the library is experimental and only one example is provided. Further examples will be added.

Working from home has become the new normal for many people, so finding the best computer monitor is more important than ever. After all, you want to see the best visual quality from your coworkers" best webcams, right? And while many PC components are still enduring depressing shortages, performing a screen upgrade is one of the most accessible and most impactful changes you can make to your gaming rig at the moment.

Why you can trust Tom"s HardwareOur expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.What’s your monitor’s purpose?If it’s gaming, you’ll generally want something with a high refresh rate (ideally 100Hz or more), low response time and AMD FreeSyncor Nvidia G-Sync for fighting screen tears at low framerates. For general use, look for high contrast, and for creative work prioritize color accuracy.What resolution do you want? More pixels means a sharper image. No one should be buying anything under 1080p/FHD (1920 x 1080) these days. But if your budget can handle it, 4K is as sharp as it gets at a reasonable price. Many gamers find 1440p/QHD (2560 x 1440) a good compromise between price and high-refresh-rate performance.Contrast and color.We consider contrast the most important factor in image quality, with 1,000:1 being solid. Color errors are particularly important avoid for content creators, and anything with a Delta E (dE) greater than 3 may show visible errors.Panel tech:When it comes to image quality, TN< IPS< VA. VA monitors typically still have better contrast than even the best IPS panels, although IPS panels are also known to be very colorful.What size do you want?These days, 24-inches is on the small side and 27 inches is mainstream, while 32-inches is a good large size for those on a budget. Anything bigger than 43 inches probably won’t fit on a regular desktop. For portable monitors, stay in the 17-inch range or under. Anything bigger isn"t really all that portable.sRGB or DCI-P3? In most cases, you’ll either be getting a monitor made for the sRGBcolor space or the more colorful DCI-P3 one. Technically, Windows, the web and non-HDR games and video all use sRGB, but if you want an extra colorful screen, an accurate DCI-P3 monitor is more appropriate.

Just know that to get the last $200 off, you"ll have to deal with an old-school rebate (where you have to mail in the original UPC). Other features include 10-bit color / 98% DCI-P3 / 130% sRGB, and a KVM feature with USB Type-C to control multiple devices. Check out our Aorus FO48U review(opens in new tab) to see why we gave it our Editor"s choice award.

Earning a 5-star rating from Tom"s Hardware, the Samsung Odyssey G7 32-inch is the best computer monitor. For gamers, it boasts the strongest curve currently available, 1000R, for incredible immersion, along with speedy gaming numbers. The 240Hz monitor has a 1ms (GTG) response time and put up a 5ms response time score in our testing, beating some 165Hz screens by 2ms. In addition, benchmarking showed input lag at 20ms, a full 6 to 10ms faster than some 165Hz screens we’ve tested, including the Dell S3220DGF also on this page.

The Dell S3222DGM is the best gaming monitor for many gamers. This follow-up to the highly-rated S3220DGF(opens in new tab) boasts a 32-inch VA(opens in new tab) panel, QHD resolution and 165 Hz refresh rate with Adaptive-Sync(opens in new tab) support. Other perks in its favor are 85 percent coverage of DCI-P3 and a display curve with an 1800mm radius.

With a 1ms (GTG) response time and 144Hz refresh rate, the LG 27GN950-B is the best computer monitor for 4K gaming. If you’ve got the graphics card, ideally one of the best graphics cards, you need to handle 144 frames per second (fps) at 4K; this monitor will ensure that power doesn’t go to waste. In our testing, the monitor showed a 7ms response time, keeping up with pricier 4K, 144Hz screens, like the Asus ROG Swift PG27UQ, and even beating some when it came to input lag. Plus, FreeSync Premium Pro and G-Sync Compatibility will fight screen tears for those times when framerates drop below 48 fps.

Although VA panels are known for their high contrast, this IPS monitor can hold its own, hitting 1,034.7 before calibration and 8,475.3:1 with HDR, based on our benchmarks. Those who want the most accurate color may find the sRGB mode too saturated, but the 27GN950-B proved accurate when it came to the more colorful DCI-P3 space.

eSports players and hopefuls rely on the fastest peripherals available to attenuate the delay between deciding on in-game action and when that action happens on screen. 360 Hz is the fastest refresh rate PC monitors have today, and the MSI Oculux NXG253R is the fastest of them all. Yes, the NXG253R is the fastest display we’ve ever tested, making it the best computer monitor for eSports you can buy.

Curves are generally more effective on ultrawide screens, but the UR59C’s 1500R curvature was effective and beneficial for this 32-incher, such as when multitasking with multiple windows. And if you don’t mind calibrating, you can get rid of the UR59C pesky color errors, which, unfortunately, were visible out of the box. Our calibration settings reduced the error from 4.3dE to 0.9dE.

Making HDR pop over SDR is all about contrast, and for the ultimate contrast, there’s nothing better than OLED. The Aorus FO48U’s massive OLED panel not only delivers immeasurably high contrast, but we recorded 107.7% coverage of the DCI-P3 color space and near-flawless grayscale tracking. As a result, you get a rich image that’s also accurate out of the box. However, it’s not as bright as a premium LCD (399 nits with HDR, according to our testing).

Aorus’ OLED monitor is fit for high-speed HDR gaming on both PCs and consoles, thanks to DisplayPort 1.4 with Display Stream Compression (DSC) and HDMI 2.1, respectively. The monitor held its own against 120Hz and 144Hz rivals in our speed tests, only falling 4ms behind its OLED gaming rival, the Alienware AW5520QF. Unfortunately, you don’t get Dolby Vision or support for the 50p and 24p TV formats, but the monitor has two 15W speakers and one 20w speaker for outstanding audio quality.

Asus has gone all out with the ProArt PA32UCG, combining 1152 dimming zones in its full-array Mini-LED backlight. A quantum dot film covers a considerable color gamut, almost 78% of Rec.2020. And it is the brightest monitor we’ve ever tested at over 1700 nits peak. To that, it adds precise out-of-box accuracy for every color mode in use today. Though it includes many calibration options and a bundled colorimeter, it’s ready for work or play, with no tweaking necessary.

According to our benchmarks, with 244 nits max brightness and 98% coverage of the sRGB color space, the ThinkVision M14 is perfect for surfing the web or watching a movie in SDR. USB-C connectivity, meanwhile, means it won’t run out of battery when plugged into a laptop. It can also deliver as much as 65W of power to a device if plugged into a wall adapter. But those whose PC or device, such as a Raspberry Pi, doesn’t have a USB-C port with DisplayPort 1.2 Alt Mode and USB PD 2.0 or better will be out of luck.

The HP Omen X 65 Emperium is the best computer monitor to replace your living room TV. First, it’s massive. It also comes with a remote and powerful audio that’ll fill your space, thanks to four 4-inch woofers, two 1-inch tweeters and a pair of passive radiators. The inclusion of Nvidia Shield means access to the apps you’d want on a smart TV, including Netflix and YouTube, plus access to hundreds of free games.

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

In electronic’s projects, creating an interface between user and system is very important. This interface could be created by displaying useful data, a menu, and ease of access. A beautiful design is also very important.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In this article, we have used libraries and advanced technics to display data, charts, menu, etc. with a professional design. This can move your project presentation to a higher level.

Size of displays affects your project parameters. Bigger Display is not always better. if you want to display high-resolution images and signs, you should choose a big size display with higher resolution. But it decreases the speed of your processing, needs more space and also needs more current to run.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The display driver will typically accept commands and data using an industry-standard general-purpose serial or parallel interface, such as TTL, CMOS, RS232, SPI, I2C, etc. and generate signals with suitable voltage, current, timing and demultiplexing to make the display show the desired text or image.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

By these two functions, You can find out the resolution of the display. Just add them to the code and put the outputs in a uint16_t variable. Then read it from the Serial port by Serial.println(); . First add Serial.begin(9600); in setup().

First you should convert your image to hex code. Download the software from the following link. if you don’t want to change the settings of the software, you must invert the color of the image and make the image horizontally mirrored and rotate it 90 degrees counterclockwise. Now add it to the software and convert it. Open the exported file and copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are sizes of image. you can change the color of the image in the last input.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

In this template, We just used a string and 8 filled circles that change their colors in order. To draw circles around a static point ,You can use sin();  and cos(); functions. you should define the PI number . To change colors, you can use color565(); function and replace your RGB code.

In this template, We converted a .jpg image to .c file and added to the code, wrote a string and used the fade code to display. Then we used scroll code to move the screen left. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We used sin(); and cos(); functions to draw Arcs with our desired thickness and displayed number by text printing function. Then we converted an image to hex code and added them to the code and displayed the image by bitmap function. Then we used draw lines function to change the style of the image. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We created a function which accepts numbers as input and displays them as a pie chart. We just use draw arc and filled circle functions.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We display simple images one after each other very fast by bitmap function. So you can make your animation by this trick.  Download the .h file and add it to folder of the Arduino sketch.

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template.  Download the .h file and add it to folder of the Arduino sketch.
