The circles should be complete and round, the lines in the frequency patterns should be clear and defined, and the color gradients should not have any breaks or banding.

Assess the uniformity of the image using various grayscales. The brightness should be equally distributed across the entire image, and the image shouldn’t have any colorful areas.

Check the extent to which your monitor can display similar colors while keeping them differentiable. You can create two color patches to do so. The more similar the two colors that can still be differentiated from one another are, the better your monitor can differentiate between the colors. This test is also well suited for making a direct visual comparison between two different monitors.

Choose a greater viewing distance to check the display of gradients. The grayscale image should be reproduced in the overall view without any unnecessary color and with an even gradient, and, at 256 intervals, there should not be any noticeable abrupt changes in brightness between individual grayscales. At a smaller number of intervals, the respective bars should be clearly differentiable from one another.

This test allows you to determine whether your monitor can reproduce text sharply and without any shadows, independently of other influences, such as text smoothing.

Test the monitor’s viewing angle stability. When you increase the viewing angle, the size and shape of the circles displayed should remain almost the same. Slight changes may appear. Less is better.

Use the slide bar to change the logo’s grayscale until the logo blends into the background to the greatest possible extent. The value shown corresponds to your monitor’s gamma value.

This test primarily serves to compare the response times of two monitors. Start by selecting a speed that creates clear streaks on the rectangles. However, you should still be able to clearly follow the rectangles visually. Then vary the distance between the rectangles until the lower edge (streak) of the one on the right no longer overlaps the lower edge of the one on the left. The smaller the distance, the shorter the response time. When comparing several monitors, select the same speed.

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.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

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.

Out of the box the majority of monitors are far from perfect when it comes to color, brightness, and motion blur calibration. With a few simple tweaks you can fix all that, however, and finally see games as developers intended. One thing to acknowledge though: calibration is a subjective process because our eyes and brains can perceive color incorrectly (see: white-gold, blue-black dress ), and because of color blindness and other issues. So even when a professional monitor calibrator is telling you that settings are correct, you may feel differently.

With the above in mind, try giving recommended and calibrated settings a few days to settle in. If you still feel uncomfortable or unhappy with the results, modify them in small increments until you’re content. And remember, your results will be limited by the quality of your monitor and the panel technology it’s using: IPS typically has superior viewing angles and colors, and TN is more responsive and less prone to motion blur.

You’ve potentially used incorrect settings for several years, and to you they look AOK. The changes we’re making could be drastic, and you may dislike them greatly. As such, go through your monitor’s menus, Windows’ options, and the NVIDIA Control Panel, jotting down old settings and any changes you’ve made in the past. That way, you can revert the changes we’re about to make and return to the incorrect settings you’ve grown to love.

Before you start your calibration efforts, install the latest NVIDIA display drivers from GeForce.com , set your screen resolution to its native resolution, for example 1920x1080 on a 1920x1080 monitor, and let your monitor warm up for 20-30 minutes (some may take longer, others less so) to ensure it"s operating to its full capabilities. If you"re unfamiliar with changing resolutions, right click the desktop, select "NVIDIA Control Panel", navigate to the "Change Resolution" tab, and select the resolution in the list that says "(native)".

In your room, eliminate any glare from windows or artificial lights, but keep the lighting bright enough that you can see the keyboard and your surroundings. If your screen is typically engulfed in glare, look for ways to reduce that on a permanent basis to improve results and reduce eye-strain, and if that"s impossible boost the monitor"s brightness post-calibration to compensate.

All monitors have a listed Viewing Angle in which the picture is supposedly clear and usable. In reality though the quality of some monitors can drop drastically the second you move off-center. Therefore, to ensure you have the best possible picture, and can calibrate your monitor correctly, switch your position permanently to one in line with your monitor, with the entirety of the screen in your field of view.

TFTCentral , Display Lag , and Prad produce some of the most detailed monitor reviews on the Internet, and in those reviews their knowledgeable editors often provide recommended monitor settings and ICC color management profiles .

Step 1) Locate settings and profiles. Check TFT Central’s Database first, and if no luck Display Lag and Prad ’s reviews second. If you’re still unable to find your monitor look on the manufacturer’s support page for ICC profiles, and try a generic Google search using

Step 2) Install the ICC profile. Copy the downloaded file to C:Windowssystem32spooldriverscolor, then run colorcpl.exe to open the Color Management window (alternatively, navigate to Color Management in the Control Panel).

Step 10) Finally, modify each monitor’s settings using their On-Screen Displays (OSD). Some can be unintuitive, so it is recommended to keep the manual on standby. If the panel’s particularly advanced you may be able to create multiple profiles or presets, and tweak power user settings that give you greater control over the picture. If you’re unsure what a setting does, consult the manual or ask online.

The quality and properties of monitors can vary from one unit to the next in production runs, so you may find the recommended settings above are ‘off’, or perhaps you simply wish to tweak to your personal liking. The easiest way to do this is to utilize a variety of online tests, and the “Calibrate display” tool in the “Advanced” tab of the Color Management application we were using above.

Online, the go-to location for any monitor tweaking is Lagom’s suite of test images . There, you can calibrate Contrast, Sharpness, black levels, and many other aspects of your monitor’s display. But what you won’t find is a good motion test, which is particularly important for gamers using modern monitors equipped with motion blur, input delay, input lag, zero lag, and other similarly named modules that reduce blurring on fast-moving objects.

The only way to get 100% technically-perfect results for your monitor is to buy, rent, or borrow a professional color calibration tool, such as Datacolor’s Spyder4 , Pantone’s ColorMunki , or x-Rite’s i1Display Pro . They’re not cheap (prices start at $99), but if you’ve already invested in a G-SYNC Surround setup or 4K monitor the extra cost will ensure you get the absolute best results. Just remember, the technology may say that the calibration is perfect, but your eyes may not believe it, or you may simply prefer a different look.

Please note that some games and applications will override calibrations and Control Panel tweaks. To workaround this problem, you can try CPKeeper and Color Sustainer .

By this point your monitor’s picture should be looking better than ever before. You may initially feel the look is bad or wrong, but give it a few days and you’ll probably change your tune once your eyes adapt. If all else fails, you can always go back to your original setup. If you stick with it though you’ll see games as developers intended, and get more accurate color reproduction in videos, movies, TV shows, and pictures.

If calibration can’t fix your complaints, however, consider a brand new monitor with superior color reproduction, reduced input lag, wider viewing angles, and zero motion blur. At the time of writing, TFT Central rates the Acer Predator XB270HU 2560x1440 G-SYNC IPS-panel monitor as the “new king of gaming monitors”, and on Display Lag the BenQ XL2430T , BenQ XL2420G G-SYNC , and ASUS ROG Swift PG278Q G-SYNC TN-panel monitors are tied in the all-important Picture Quality, Input Lag, and Response Time categories. If you don’t need anything quite as fancy though there are plenty of other great monitors out there that should provide a superior experience, reducing eye strain and making your games and multimedia look better than before.

This new library is a standalone library that contains the TFT driver as well as the graphics functions and fonts that were in the GFX library. This library has significant performance improvements when used with an UNO (or ATmega328 based Arduino) and MEGA.

Examples are included with the library, including graphics test programs. The example sketch TFT_Rainbow_one shows different ways of using the font support functions. This library now supports the "print" library so the formatting features of the "print" library can be used, for example to print to the TFT in Hexadecimal, for example:

In the library Font 0 (GLCD font), 2, 4, 6 and 8 are enabled. Edit the Load_fonts.h file within the library folder to enable/disable fonts to save space.

TFT_ILI9341 library updated on 1st July 2015 to version 12, this latest version is attached here to step 8:Minor bug when rendering letter "T" in font 4 without background fixed

Hi guys, welcome to today’s tutorial. Today, we will look on how to use the 1.8″ ST7735  colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored display or something bigger with additional features, that’s where the 1.8″ ST7735 TFT display comes in.

The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.

Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:

We will use two libraries from Adafruit to help us easily communicate with the LCD. The libraries include the Adafruit GFX library which can be downloaded here and the Adafruit ST7735 Library which can be downloaded here.

We will use two example sketches to demonstrate the use of the ST7735 TFT display. The first example is the lightweight TFT Display text example sketch from the Adafruit TFT examples. It can be accessed by going to examples -> TFT -> Arduino -> TFTDisplaytext. This example displays the analog value of pin A0 on the display. It is one of the easiest examples that can be used to demonstrate the ability of this display.

The first thing, as usual, is to include the libraries to be used after which we declare the pins on the Arduino to which our LCD pins are connected to. We also make a slight change to the code setting reset pin as pin 8 and DC pin as pin 9 to match our schematics.

Next, we create an object of the library with the pins to which the LCD is connected on the Arduino as parameters. There are two options for this, feel free to choose the most preferred.

All the functions called under the void setup function, perform different functions, some draw lines, some, boxes and text with different font, color and size and they can all be edited to do what your project needs.

Uploading the code to the Arduino board brings a flash of different shapes and text with different colors on the display. I captured one and its shown in the image below.
