I own Samsung LN40B550K LCD HDTV from 2009 that fortunately supports PC Mode, which uses 4:4:4 chroma subsampling when in HDMI -> HDMI mode with working audio. The problem I ran into is that 4:4:4 only works when using a refresh rate of 60Hz. When I switch to 24Hz to watch 24p content, my TV goes into 4:2:2 24Hz mode, which provides the sharpest image for 4:2:0 content. If I remain in 60Hz 4:4:4 mode while playing 24p content, the image is somewhat blurrier and there is more judder, unless I use Smooth Motion in madVR. Is it normal to have blurrier image when playing 4:2:0 content on a 4:4:4 screen? I take it the TV converts 4:2:0 content to 4:4:4 which reduces image quality, right? Is there a way to fix it? I use my power-gaming rig with MPC-HC, madVR (high quality upscaling & downscaling settings), and LAV Video Decoder with nVidia CUVID decoding and acceleration, which provide me with great image quality.
The reason why I don't want to just switch to 24Hz 4:2:2 mode for 24p content is because it needs a completely separate calibration that would mess up my 60hz 4:4:4 calibration. I calibrated 4:4:4 60Hz to D65, but when switching to 24hz 4:2:2 - my contrast, gamma, and RGB are completely off. There does not seem to be a way to calibrate my TV for each refresh rate/chroma subsampling. I would have to re-calibrate many factory settings each time I want to watch a movie and then do it again to play games. That is crazy... I tried using other profiles (like Standard instead of Movie) but they lock me out of several important calibration options..
So, is there a way to play 4:2:0 content on a 4:4:4 screen without making it blurry? LAV Video Decoder can output in 4:2:0, 4:2:2, 4:4:4, RGB, 8-16bit formats. but choosing any of them makes little to no difference.
Any advice will be greatly appreciated! Thank you!
