Still the same thing unfortunatly...

I was thinking, my display (JVC X5000) uses e-shift technology, this means it does accept 4K input , but the native panel resolution is 1080P. The nvidia driver does list the 4K resolutions but is says "native" at the 1080P resolution, maybe this has something to do with it (downscaling, the upscaling again maybe, although madvr stats do not show this)?

I also checked with gpu-z, GPU is not throttling its running at max clock speed.

Hi @tingtong5,

Unless I'm misreading it, the picture of your projector seems to show some wonky scaling going on (possibly causing your increased load).

3840x2160 is the resolution of the video? It seems to be cramming it into a smaller space. Also, if it's 4k material and you can output at 3840x2160 then no upscaling of luma should be happening. I'm sure someone will correct me if I'm wrong here..

Some ideas..

try setting 2160p23 in "display modes" in madVR and start playback
try disabling crispen edges while you're debugging

At github Krypton 17.1 is final. I hope aracnoz will release a new version of DSPlayer with new bug fixes / features as Krypton 17.1 is final but meanwhile i have merged the PRs from Krypton. If you like you can test/use my build.

Krypton DSPlayer 17.1 final my own build.

Thanks for this BTW, been running it for a few weeks without any obvious issues
