Ultimately, in a nut shell, the following is what I was able to achieve.
#1
Windows HDR --> OFF
Under LAV Video Configuration -> Hardware Acceleration
If I set "Hardware Decoder to use" to "DXVA2 (Native)"
This method allows LAV/MadVR/MPC-BE to playback UHD HDR MKV flawlessly! No skipping. No lag. No frame rate or choppy playback issues. Playback is absolutely smooth.
HOWEVER -- The PQ is just not that great! Colors are no different then watching a non-UHD, non-HDR media.
#2
Windows HDR --> OFF
Under LAV Video Configuration -> Hardware Acceleration
If I set "Hardware Decoder to use" to "DXVA2 (Copy-Back)"
This method allows LAV/MadVR/MPC-BE to playback UHD HDR MKV with choppy playback issues. Playback is jerky. It's not as bad as I originally encountered. This is more like when you try to play 24p video on a 60Hz refresh rate - maybe a little more jerk then that.
HOWEVER -- The PQ is phenomenal! Colors are great! I can tell it's very different then non-HDR media.
For both above tests,
"Trade quality for performance" all boxes were checked;
almost all other options were either the "default" MadVR or the ones suggested by brazen1 in post #205.
Chroma upscaling was Cubic
Image downscaling was Cubic
Image upscaling was Lanczos
I tried some other settings randomly but they only made playback worse.
Lastly,
#3
Windows HDR --> ON
Playback UHD HDR MKV in PowerDVD 17
Absolutely flawless media playback - Smooth - No choppiness/jerk.
Absolutely phenomenal PQ. Superb colors. I can tell HDR is working properly.
The only drawback of this issue is, I have to turn HDR in Windows Display Settings On & Off manually before & after media playback.
----------
If I had to pick a method to use on my machine today, I would most certainly go with method #3. Despite having to turn HDR On & Off, as I get absolutely flawless media playback with superb PQ & Colors.
Ideally, I would love if method #2 could work - if I could somehow get rid of the choppiness and jerk in motion. Since no manual HDR On/Off intervention is required.
I don't seem to quite understand why LAV/MadVR/MPC-BE cannot play back the same media on the same machine and produce the exact same picture quality & colors --- that PowerDVD can? In other words, why does GT 1030 fail to produce the exact same results in MPC-BE/MadVR, but produces brilliant results in PowerDVD? I've compared the PQ between the DXVA2 (Copy-Back) method & PowerDVD method and neither of the two is superior - they are pretty equal. So I have to relent that GT 1030 is fully capable of UHD HDR MKV playback.
Really wish I could get method #2 to work. But for now, I'll stick with method #3 unless I can figure out otherwise.
Thanks.
i have a similar hardware, older i3 and a 1030. Did bought the 1030 to get 4k hdr playback on my philips 65PSU8102 TV.
Sadly, running into the same issues, that the MPC/LAV/MADVR doesnt work! Regardless what i have tried in the settings.
Dont want to spend more money on this. So i am looking for a solution for my current hardware....
So here are my questions to you, because you are have worked out the best solutions for this hardware on the past pages:
- what external player do you use for HDR UHD mkv's in kodi?
When i have understand the discussions right: DVDFAB 3, right?
- Does PCF work correctly now in v18a3 64bit windows build?
