A small change in the image brightness should be displayed as an equivalently small change in brightness. Update avatar. I also tested 1080p … Your PC is sending the WCG(Wide Color Gamut)/BT.2020 metadata as well as other information to the TV which triggers its HDR mode, but the PC is still only sending an 8bit signal. As for the term "banding" it really should be used to describe colour banding, not bad screen uniformity In the respect of colours, or HDR colour explicitly (all TVs now are as good as one another with SDR colour) OLEDs do better with colours closer to black which is easier for the human eye to see. Basically, 8-bit 1080p/4K = no color banding at all (HDR and YCC 4:2:2 disabled). Every … This combination results in the appearance of bands of colors on the screen. We’ve been using some of the excellent tools available in a beta version of the disc for the past few months and have found things like the moving star field pattern (great for evaluating blooming and dark shadow detail, … It displays a wide color gamut for HDR content and gets bright enough to make highlights pop. The OP's 10 bit color gradient test video file played from a USB drive into the embedded Sony X850C Video Player run time app shows it to have a 10 bit panel . With the setting turned on, the TV advertises 10-bit compatibility, and the Vero then tries to correctly output 10-bit colour, but it is unable to establish a stable HDMI connection with the TV for the higher bit-rate signal. I also shared the debugging logs in my first post with this setting enabled. Definitely don’t do that. No, the “HDMI Ultra HD Deep Color” is not turned on. I understand the OLED brightness for HDR should be set to 100 to allow the full range of HDR come into play.

If you have changed the white balance or color settings and find your TV has banding, try restoring those settings to defaults and see if that solves the problem. The perceptual quantizer (PQ), published by SMPTE as SMPTE ST 2084, is a transfer function that allows for the display of high dynamic range (HDR) video with a luminance level of up to 10,000 cd/m 2 and can be used with the Rec. This tool will clearly show you the differences, Not sure how big of a TV you should buy? The final gradient score is determined from the test result and calculated to give the final gradient rating. 8-bit TVs can use dithering to generate a picture that looks very much like it has 10-bit color depth.

Just the picture frame and “no signal” displayed. I noticed the same issues during the beta, where after entering a game the HDR brightness slider is blurry and doesn't affect the picture. Be the first to start a discussion about Gradients on TVs: Color bit depth. This seems to be related to the now solved HDR … (They’re not very expensive). Well, the end-result is the same: the Vero is sending out 4K 8-bit instead of 4K 10-bit because of the TV’s apparent limitations. - With HDMI 2.0b devices you will also get tons of banding in HDR mode while PC Label is selected (this is an old LG problem). Our picture test captures the appearance of gradients on a TV’s screen. Its a bit different because of some of the intricacies of how the new formats are represented. Yes, I already did that, with the same result. Logo luminance is set to "Low" and I let the pixel refresh run whenever it automates. Shields Netflix HDR also has no colour banding but I don’t think that uses the shields native exo player either and uses its own player like kodi does. I’ve tried all HDMI inputs, and its the same for all. That is how it looks like with HDR disabled. A 10-bit display is only useful if you are watching a 10-bit content, which is really rare. HDR enabled . Your TV appears to also have a simulated UHD mode that it applies to regular content by default and this may be what your looking at. Shields Netflix HDR also has no colour banding but I don’t think that uses the shields native exo player either and uses its own player like kodi does.
