So I finally got a 4K Apple TV and it looks great when I’m looking at HDR material, but if I try to play any 2160p non-HDR file, the image appears washed out and colors look very drab (mind you If I play Comcast which isn’t even a 1080 signal, colors and everything look great) Any ideas how/why to get the SDR content on my OLED to display correctly?
I don’t have any issues. What’s the content you’re trying to play? What version is your ATV4K set to? Do you have ‘Match Dynamic Range’ and ‘Match Frame Rate’ enabled? What is your ATV4K output and format set to?
That bitrate seems really low., it seems you got a remux which could be part of the problem. Hard to say what the issues is unless you have the source content. without a more detailed mediainfo readout, it will be hard to say what could be the issue or if anyone else has the same file to test.
Personally I haven’t run into any issues picture wise with my B7A (ATV4K goes through a Denon 930H). “drab” movies look “drab” (as they should) and movies with “pop” have “pop”. Ive made a “few” personal backups and since I go for quality, my bitrates tend to be between 25 and 39Mbps for video. I haven’t run into something that looks worse than the source (which could be the issue here). If the source isn’t great, the resulting file wont be great.
Many TVs have image settings specific to each source.
So check the image settings you have when watching Comcast (which you like) and apply the same settings when using the Apple TV.
Also, I do not know if this a factor, TVs (including LG’s C7 OLED) have per-HDMI HDR switches (called UHD color for example). This is automatically enabled for the HDMI input (at least on the C7) when you connect an HDR source.
So maybe with this enabled, when you output SDR content on this HDMI input, colors could be altered and look dull.
So you could try turning this off, or plug the Apple TV to a different HDMI port (and answer no the HDR/UHD color question in the TV, or before switching hdmi input just set the Apple TV to output SDR with dynamic range matching off).
Which adjustment is better for a hdr capable 4K HDR - TV & AVR set?
Setting the basic video output to 4K 60Hz HDR and let it auto change to sdr if video has sdr
Setting the basic video output to 4K 60Hz SDR and let it auto change to hdr if video has hdr
Any comment, any advantages between both basic adjustments?
I’ve read (but now cannot find, of course) that setting it to SDR is better as some apps don’t have a range set. Things like Hulu dont have HDR shows, so they don’t bother to declare a range when you start watching something - meaning if your atv is set to HDR, it will treat that Hulu video as HDR even though it isn’t.
I don’t know whether or not this has an impact on picture quality.
