MadVR and color banding
Hi guys,
in those days I've compared my stand alone UHD player (Oppo UDP 203) and my htpc with MadVr.
The quest is what is the best for viewing UHD HDR10 Films.
My HTPC is windows 10 based (64bit), GTX970 (latest drivers), last stable madvr, MPC-HC, last LAV filters.
My display is a Sony VPL-VW520ES 4K projector.
My reference UHD material are the first mins of REVENANT and some other particular scenes taken from VALERIAN.
Obviously MadVR is better from any point of view (detail, colors, noise, ecc.) less one ... COLOR BANDINGS!
Oppo is better only under this point of view.
Oppo send a HDR signal 422@12bit to my projector.
Initially my GPU was setted in RGB@8bit.
That's why I read (a long time ago) that MadVR natively works in RGB domain.
Into MadVr I've set display=8bit
Conversion to HDR > SDR with bt.2084.
Debanding filter to Max
dithering = ordered
The image is stunning but color banding is unfortunately present.
After that I've decided to put my GPU in 422@10bit output.
Setted MadVr with display=10bit
Conversion to HDR > SDR with bt.2084.
Debanding filter to Max
dithering = ordered
Now MadVr reports me "window exlusive mode" =10bit
In this mode the color banding effect is a little bit lower ... but Oppo is still better under this point of view.
Can someone tell me if I'm missing something?
Someone can help me to put my htpc to perform bandings equal to my oppo player?
Thank you so much
