Have "D3D11" under "D3D presentation" in the DSPlayer settings, unless you mean a different option.
Windows HDR  is enabled for my TV, as otherwise it won't activate with the latest driver versions, unlike older drivers which I can't use on my RTX 2080.

Another way to circumvent the unwanted switch to HDR is to disable "adjust display refresh rate", but I obviously don't want to play 24 Hz SDR videos in 60 Hz.

[spencerjford]

odd, because with my nvidia 1070ti as long as I use refresh rate changing, it goes into HDR with the latest drivers, not using windows HDR.   But if you have windows hdr toggle on everything is going to be "hdr" no matter what you do.

[Yappa]

Interesting, what drivers are you using?

Edit:
Missed that you wrote "latest drivers". But still, what version exactly? I'm currently on 417.35.
Well, good to know, then, that disabling Windows HDR is apparently really still the way to go.

[spencerjford]

Same version.

I do not think I am the first with this issue, as I have tried to read up on similar issues. But I have not seen many working fixes apart from shortcuts rather than stopping it happening.

Due to limitations with my AVR and 4K, I have had to use a DP to HDMI adapter to take Audio from my nVidia GTX 1050 to my AVR and Video straight to my TV. This has created many more issues than I thought not only with KODI but Explorer/Chrome and the likes minimizing to the other desktop, which does not exist, there are ways to get things back and or trying to make sure apps stay on the main desktop, but a lot of the time they seem to do what they want. I tried Ultramon which did help but it sometimes created issues and left me with a non functioning NVCP limited to 1080p.

KODI has been a real pain, at one point it all went away, I had my desktop and KODI at 2160p and everything was working well to a point and I had limited issues with KODI minimizing or jumping up to the top left corner, things like \\ helped get it back, but the only sure fire way I seem to have locked KODI down is to set my desktop at 2160p and 23 Mhz, this seems to stop KODI having a melt down, the strange thing is everything is upscaled to 2160p, so everything has to go into this resolution, but it was only the 4K UHD files that when exited would make KODI jump to a non existent desktop and sometimes I had to close KODI down from the taskbar to then restart.

KODI would also restore to the desktop a lot of the time saying keep new settings, it was as if it was changing resolution, but you have no idea what to, I thought if I locked the settings down this would stop it, but it had no effect, and the screen would bounce up and down to the taskbar or some other annoyance.

Anyone have any other ideas what to do here, as its really ruining the KODI experience for me right now.

Does not seem to be a driver issue as its common to old and new. I have set the 2nd non existant desktop to 800x600 which helps losing the mouse etc, but you cant just disable the 2nd desktop as you lose sound, if you go below 800x600 you lost HI-RES audio, what a mess

I haven't tested it, but I've heard you need to extend the desktop when using the DisplayPort to handle HD audio.

 Yes that is correct, but due to the way HDMI works, Windows sees it as a 2nd display, this is what creates all the issues, if you disable the 2nd "fake" display you lose audio, if you keep the display, it is a total pain with things wanting to minimise or go to that screen. The only workable fix is to keep the desktop at 2160p 23hz, as for some reason it does want to jump to the other display.

[Warner306]

I see. I don't know where to send you to find an expert. I know there some people in the AVS Forum HTPC forum that use that combination successfully.

 Ok will keep looking, from what I have read and seen so far and selecting debug mode. It looks like when KODI trys to revert back to 60 from 23 it seems to want to move KODI to the other screen which does not technically exist. Hence why keeping the desktop at 23 stops it getting lost or whatever it is actually doing.

There are apps like Desktopfusion that I am reading up on now that may help, just a pain having to use different things to stop it moving.

i was just thinking that maybe people having problems with 4K cards such as 10xx etc.etc are using older MB's that are only PCIe 2 standard rather than the 3 standard that the cards might need to run at full bandwidth.

[Warner306]

PCIe 2.0 x16 shouldn't perform that much differently than PCIe 3.0 x16 with current GPUs, especially if D3D11 Automatic Native hardware decoding is used. That certainly wouldn't impact refresh rate switching and desktop focus.

[Bibio]

as far as data rate is concerned its a massive difference. it also handles data differently. https://en.wikipedia.org/wiki/PCI_Expres...xpress_2.0

if it were not for the fact that it would cost £300 to upgrade i would test the theory out, maybe in a few months... lol

[Warner306]

I've already tested a GTX 1050 Ti with a PCIe 2.0 x16 motherboard and it performed almost identical to a GTX 1050 Ti connected to a PCIe 3.0 motherboard. 16 lanes provides plenty of bandwidth at PCIe 2.0 to handle the load of current GPUs without any data bottlenecks.

Your profile rules would look something like this:

if (srcWidth > 1920) "2160p"
else if (srcWidth <= 1920) and (srcHeight > 1080) "2160p"

else "Other"

To create the profile rules, follow the logic from the link posted above. You should also delete the fake DSPlayer profile groups.

Thanks "Warner306" @

Every time I delete the "fake DSPlayer" profile in madVR settings, the next time I start playing any video in Kodi, the fake DSPlayer profile gets automatically created.  What do I need to do so DSPlayer doesnt try to create the same exact profile every time I start playing a video?



EDIT:  Also, is there any way to download and import the sample 1080p/2160p presets from, "6. SAMPLE SETTINGS PROFILES & PROFILE RULES..."? It would be nice to be able to easily share and use madVR presets.

[Warner306]

You need to change - Manage settings with Kodi from Load and Save with DSPlayer database to Load from madVR active profile.

You could download those settings if I created a .settings.bin and posted it. I'd prefer not to because madVR is changing all the time and that settings.bin will become obsolete on a regular basis.
