    Also this non-curved model from LG: https://www.amazon.co.uk/LG-Ultragear-27GL83A-B-27-Inch-Compatible/dp/B07XLDLZPF/
    I don't like the LG Ultragear.
    Poor contrast and oversaturated colors. Also, the panel is known for causing eye problems and headaches. The same applies to the successor (27GN850) and the Dell S2721DGF, which have the same LG Nano IPS panel installed.
    So, what 4K UHD monitor do you recommend? The member asking about monitors asked about the Dell S2721QS and the ASUS ProArt Display PA279CV. Are they OK?

    Do you know what frame rates are supported for 4K AV1? Full 60 fps? Or limited to 24 or 30 fps?
    Sorry for forgetting to get back to this. I downloaded a 4K AV1 video 60fps video from https://www.youtube.com/watch?v=LXb3EKWsInQ

    Tiger Lake's QSV was able to play the video smoothly with continuous audio and tone mapping for HDR when I used the Microsoft Movies and TV app. When I played the same file using VLC, MPC-BE x64, and PotPlayer 64 bit they all successfully applied tone mapping for HDR but either video playback wasn't as smooth, or the audio cut in and out, or both.
