I found this chroma subsampling test on this page. Offer available with LG 8K TVs and LG 4K TVs on 2016 to 2021 models. Each pixel has its own switch-off and switch-on system.
There are millions of pixels within the 65-inch OLED display. It brings you the brand-new self-lit pixel technology. To redeem, click the Apple TV+ banner on your smart TV’s home menu or LG Content Store and follow the instructions. In other words, having an HDMI 2.1 port on your TV does not guarantee that the port in question will support features like 4K/120Hz (and having an older standard doesn't guarantee it won't). The LG OLED C1 65-Inch 4K Smart TV is one of the best choices for high-end smart TVs from the house of LG.

I will do the test as soon as possible and update this post if necessary. Sink in and watch some of the best TV out there on some of the best TVs out there. 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. As you might expect I'm asking because I have a TV (LG UK6300) that doesn't detect a signal from a pi4. 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.
