![]() ![]() ![]() So, I tested the LG 49UB850V + GeForce GTX 970 with this chroma torture image and here are the results:Īt 4k 30Hz, the last lines are perfectly readable: the 4:4:4 chroma subsampling is in use.Īt 4k 30Hz (the GTX 970 is plugged on the HDMI 3 port, with R344.75 driver for Windows 8 64-bit), the last lines are deteriored: no doubt, the chroma is not 4:4:4: but rather a reduced version (4:2:0).Īccording to some sources, the LG 49UB850V supports 4:4:4 at 4k / 60Hz. Just display the following image with any PNG viewer (by reading this page in your browser for example…) and if you can perfectly read the last two lines (with read and blue background, as well as some other lines like the blue and pink ones) then the chroma subsampling is 4:4:4. Today I found a test that brings the answer in no time. Was it 4:4:4 or rather a reduced format like 4:2:0 ? At the end of this article, I said that I had some doubts about the chroma subsampling used with the LG 49UB850V + GTX 970 at 4K/60Hz resolution. ![]()
