If none of huhn's recommandations work, you can also try an older driver that still works with your newer card, or file a bug report with AMD. Another trick: if you use your HTPC mostly for video, you can set your desktop at 720p and configure the media player to switch to 1080, then in the Radeon control panel you configure 720p with 3% underscan and 1080 with 0%. You'll still have the issue with GUI elements at the edges being cropped in MPC-HC, but it's a lesser problem than having the desktop GUI cropped IMHO.

I got similar results with two different displays when changing the gamma settings at the display and madVR. It could be some deficiency of the gamma tracking near-black, but who knows. They don't crush black with SDR content.

Yesterday I checked 2.4 gamma with black and white clipping of hdr10 test patterns, again, and there's no issue at all.

[QUOTE=huhn;1862500]the market share of polaris cards is close to none existing and this will not change.
https://store.steampowered.com/hwsur...lcome-to-Steam Yeah but thats steam, those figures are going to be massively skewed toward gamers, you cant call that "the market share", Most HTPC owners could own AMD cards, we just dont know. NVIDIA cards arent just a bit faster according to some, they decimate AMD in NGU, surely further optimization is required, got to be a reason for this?

the reason should be an architectural difference that can't do the needed calculation fast enough or yet another driver bug.
NGU and polaris release time is very similar and it was very fast known that polaris doesn't perform well if i'm not mistaken i was one of the first if not the first to notice and investigate on this. Quote:
fermi was decimate by GCN 1.0 for nnedi3 too this got better with kepler and was fixed with maxwell where AMD didn't even compete anymore and just refreshed old cards over and over. and even then AMD was still faster and AMD had a bug where it lost about 50 % performance while decimating nvidia. the 7850 and the r9 270 classics. good old times. the fix not getting an nvidia card if you wanted nnedi3. |

i guess well have to hope AMD comes out with some new architecture at some point which works better, i'm happy with what my 580 can do for what i paid for it so i guess thats all that matters at the end of the day.

If you own an nvidia GPU and if you are trying to create a custom resolution with custom timings in madvr, this is the way to go, I couldn't to it with another method. Hope this reply will bump your answer so guys with the same problem as me won't spend hours on Google like I did... |

I kept telling people for a long time to use CRU to create custom resolutions. It works around any quirks in any APIs, because it just doesn't use any. Let madVR figure out the values if you want, and just put them into the EDID with CRU.

Heres one
http://madvr.com/crt/CustomResTutorial.html https://forum.doom9.org/showthread.php?t=173571 Not used it myself, but I had more success with nVidias, I also do not understand why people want the 10 and 12 bits, the more I read the more I understand it is a waste of time and you are just as well with 8 bit RGB.

That doesn't mention CRU. It isn't that complicated. You only need to create one custom resolution and simply copy the values calculated by madVR into CRU.

Well the post I quoted 5 posts above explains it quite well.
But TBH it does not work as flawlessly as I hoped. Every time I reboot I still need to manually pick a 12bit mode (e.g. 2160p30 @ 12 bits) in nvidia CP first. If I don't, the 2160p23 custom res madvr autoswitches to sticks with 8 bits. However once i've done this first, then when playing a 23p source, madvr will autoswitch from whatever resolution is active (e.g. 2160p60 8 bits) to my custom 2160p23 res in 12 bits. So in the end it works, but not without bumps, which is to be expected with such a quirky method, I guess... Last edited by Charky; 12th January 2019 at 15:13. |
