Hi Warner, I did exactly that and it worked!!! ~~~ But not exactly the first time round.
Changed all the display modes from 1080 to 2160 and played back a UHD demo of Star Wars. MPC-HC launched and the resolution switched to 3840x2160 with MPC-HC in windowed mode (Yay!!!). However, an error message popped up and referenced some memory issue and the video did not play (Noooo!!!).
I suspected that it might be due to the display resolution settings in the 1080 mode that was causing this, and so I closed the video which returned the desktop to 1080 resolution (you were right), and changed settings to RGB full 8bits (from YUV444 limited 12 bits). I then tried playback again and this time it worked!!! The trailer started playing in MPC-HC full screen exclusive mode at 3840x2160 (checked via OSD). However, I noticed that the dark areas of the scene were too bright and seemed slightly grey. Also, my TV is an edge-lit LED and I could see some light leakage from the edges and corners of the TV. This usually only happens when I've got the brightness on way too high. Any ideas what might be causing this?
So, I exited the movie and changed the settings in the 1080 display resolution to YUV444 limited 8 bits and tried again. 3rd time's the charm!!! The blacks remained dark and playback was smooth at 3840x2160 full screen exclusive mode. I also tried playing 1080p and 720p movie files to see if madVR would upscale them to 2160 and play at 3840x2160 resolution. It did!
However, all the 720p/1080p/2160p content played in 3840x2160 full screen looked quite soft/flat and the colours were not as vibrant. It actually looks better when I play them in 1920x1080 desktop resolution and let the TV handle the upscaling. I haven't actually gotten around to tweaking the madVR upscaling/downscaling/doubling/rendering settings, but was hoping that default madVR settings would at least match the upscaling done by my TV. I'm assuming that I should be able to get a better picture after I'm done with customising madVR settings compared to the TV upscaler right?
The below is what I'm thinking as a default setting, and was wondering if I could use them for all 720p/1080p/2160p content rather than create several profiles for each?
chroma upscaling: NGU Sharp high quality
image downscaling: SSIM 1D 100%
image upscaling: I'm going to go with doubling as I can only choose between upscaling or doubling
image doubling: NGU Sharp {luma doubling high. and the rest let madVR decide)
dithering - Error Diffusion - option 2
What do you think of the above settings? Thanks!
