If you own any device with a screen, such as a phone, monitor, or TV, and you want to check the quality of the screen, you may think that it is possible to do this very easily. How can you find out the quality of your device’s screen.
I don’t mean the workmanship of the display, we’re talking about the quality of color reproduction, the depth of color in the screen.
How screens differ in color reproduction
Screens can differ in the quality of the shades transmitted. Manufacturers use a large number of different designations of screen quality. The most common are the color depth in bits. 6 bits, 8 bits, 10 bits. Less commonly used designation of any standard, if the possibility of the screen does not meet the stated standard indicates the percentage ratio. For example, you can see the description, the monitor supports the color space sRGB 125%. The figures are big gives the impression that this is a good monitor. But you should know that sRGB standard was invented as a simplified RGB standard, for web pages, monitors.
But the most understandable designation of picture quality, indicating the depth of color
What screens are used
Conventionally screens can be divided into three categories.
Entry-level screens – cheap screens, installed in entry-level devices
Good quality screens – these screens are installed in devices of average price segment SUHD
Premium screens – installed in premium devices, these screens QLED, OLED.
Test the quality of the screen of your device
You can read on some sites, upload a picture to test the screen quality of your device. For example you are shown a picture and they say for someone it is just a square with a uniform fill, and someone there will see the image. This is the screen quality test. The picture is made with an expanded color range.
But this is not true you can not in an ordinary browser or picture viewer to assess the quality of the picture. The most common JPEG and PNG file formats only support 8 bit color. To check the quality of the picture, you should show on your TV or other device an image format that supports 10 bit color depth, such as a picture in RAW format. But to do this, you need special programs that can read this format.
Which screens support an extended color range.
Extended color range is not supported by all screens. If your device has an IPS or VA screen, this screen most likely does not support the extended range. OLED and QLED screens do. Only when viewing HDR videos will you be able to see the expanded color range. Please note: Every person’s perception of color is different and the perception of an image with 10 bit color depth is individual.
How to check the quality of the screen of the TV, monitor, phone.
To check the quality of the image the number of playback shades, without special pictures in certain formats is impossible. Therefore, device manufacturers indicate technical specifications sometimes quite interesting parameters, such as IPS matrix with a color depth of 10 bits. But such quality in IPS matrix is technically impossible.
