![]() It's also important to make sure that Windows scaling is set to 100%. If none of the text blends together and shows artifacting, then the TV and mode you are using does not use chroma compression and is showing chroma 4:4:4. Just open up our test pattern in Windows Paint using a PC, then observe it and check if any of the lines and text are blurred together. Testing for chroma subsampling is very easy. Most gamers should therefore not worry about it. While some PC games that have a strong focus on text might suffer from using chroma subsampling, most of them are either designed with it in mind or implement it within the game engine. The higher the resolution and pixel density of future displays, the less apparent subsampling artifacts become. This becomes especially true as we move towards 4k and beyond. If anything, it would raise the costs of distribution by far more than its comparative visual impact. There is virtually no advantage to using 4:4:4 for consuming video content. It would be tough to recognize the difference between a full 4:4:4 sequence and the same content in 4:2:0.Ĥ:2:0 is almost lossless visually, which is why it can be found used in Blu-ray discs and a lot of modern video cameras. The benefits of having full color in video are debatable, especially at 4k. Now, its importance with smaller text is undeniable, but what about with movies? 4:2:0 subsampling has been an industry standard for a long time now, and it isn't without reason. It's also important to note that subsampling on a PC requires using the YCbCr/YUV format as RGB does not support it. It usually makes standard text look fuzzy and reduces its clarity. While this pattern showcases an extreme case, similar side effects are visible in normal usage as well. While 4:2:2 fares better than 4:2:0, it still isn't what most would consider acceptable. The text is all muddled together, and a lot of it is completely unreadable. Samsung UN55JU7100 4k 60Hz outside PC modeĪs you can see, the lack of detail is clearly apparent in the bottom two rows. Because of bandwidth limitations from internet speeds and HDMI, this makes for much more efficient use of current systems. In the YUV format, luma is only 1/3rd of the signal, so reducing the amount of chroma data helps a lot. This allows you to maintain picture clarity while effectively reducing the file size up to 50%. What chroma subsampling does is reduce the amount of color information in the signal to allow more luminance data instead. Color information, chrominance, or simply chroma is important as well, but has less visual impact. ![]() For example, a black and white image will not look less detailed than a color picture. ![]() Luminance, or luma for short, defines most of the picture since contrast is what forms the shapes that you see on the screen. This reduces bandwidth without significantly affecting picture quality.Ī video signal is split into two different aspects: luminance information and color information. What is Chroma Subsampling?Ĭhroma subsampling is a type of compression that reduces the color information in a signal in favor of luminance data. After all, what good is a display that has no way to transfer the signal from the player to the device? One of the easiest ways to transfer more data is to compress the image, which allows for more information to be sent through the cable than it could normally support. Then, there you will see the number that represents you're currently using screen/monitor resolution (in pixels width and height).As displays have gotten more advanced, supporting ever higher resolutions and faster refresh rates, one of the biggest limiting factors in their development has been the available bandwidth of the cables that connect our devices. Click on the icon, it will be open on the new page.ģ. Just (Add to Chrome) install the extension,Ģ. How to check your device Screen Resolution?ġ. This means that the screen has 1024 pixels horizontally and 768 pixels vertically (or 1366 pixels horizontally and 768 pixels vertically, and so on). The number of pixels horizontally and vertically is shown as the screen resolution. These pixels are arranged in a grid horizontally and vertically. It's simple and easy, there is no need to do to find out your screen resolution.Ī computer screen uses millions of pixels to display images. It helps you to find out the screen resolution of your computer/laptop monitor (Windows 11/10/8/7 or Mac), Android Phone, iPhone, iPad, MacBook, tablet or any display device in pixels. If you are looking for a Chrome Extension to know what is my screen resolution, then you are in the right place. Are you want to know what is your screen resolution? Using this extension, check your screen/monitor resolution instantly for free!
