Full Screen Doesn't Work with AMD 780M Graphics

[scott750]

I got a new mini PC, MinisForum UM780XTX with AMD 7840HS and 780M graphics. In a windowed screen everything plays great. But in full screen the image is black and the cursor flashes making WMC un-viewable. Weird thing was during EPG123 setup, I was able to perform the WMC setup in full screen without any issues. I'm running WMC v8.9.1

I do have Full Screen optimization disabled.

Any suggestions?

Interesting. AFAIK, it's the first report of a graphics issue affecting a non-Intel-11th+ (i)GPU.
When you say you disabled fullscreen optimization, which one are you referring to? The one you can tweak via Windows or the DirectX 9 exclusive mode used by WMC (internally called "fullscreen optimization")?

I am like you in thinking only Intel iGPUs had the issue, not AMDs. The tweak version in Windows by right-clicking on the WMC icon and modifying the Properties is what I did. Thank you for sharing the link. I checked my registry for the following line but it did not have it. So I manually added the line and will reboot my PC later after the current recordings complete.

Code: Select all

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Settings\DisplayService]
"DisableFullscreenOptimizations"=dword:00000001

It's important to note that this registry key has no absolutely effect if you don't use a patched version of ehshell.dll: either the one attached to the thread I linked or the one that is part of the new WMC mini-mods patcher: viewtopic.php?t=14526

Oh ok. I thought the patched eshell.dll was referring to v8.8.5 only. I will try it with v8.9.1. I would need to uninstall WMC and reinstall with the patched file right?

If you go the mini-mods route, you can directly run the .cmd contained in the package: it will overwrite the mcepg/ehshell .dll in ehome, ensure the GACed version is hardlinked to the ehome folder and re-run NGEN to update the native images corresponding to these two .dll.
If you don't want to use that tool, I'd recommend uninstalling WMC, downloading the 8.8.5 installer and replacing the .dll in the package before reinstalling it. Your WMC configuration will likely be lost in the process, tho'.

or you can use epg123 to backup your config /uninstall /reinstall, configure thru tuner setup / restore epg123 backup

I don't know what that does to the patch(es). If you have to repatch after all that it probably makes more sense to use the tool in the first place.

Kevin thank you so much for your help! Running your Mini-Mods app ultimately did the trick.

I originally first tried uninstalling v8.9.1 and installing v8.8.5, but still got the fullscreen issue. Then I tried replacing the ehshell.dll file with the patched file, but still had the issue. Then I ran the Mini-Mods app on v8.8.5 and fullscreen is working perfectly!

I tried the Maxifier app before all of this which didn't help. Is there a way to delete that app?

Also how do I know if the Windows DVD player was installed with v8.8.5? Gary's post made it seem like I would see something during the install but I did not see a note during v8.8.5 when installing. Maybe since my recordings play fine it was installed? viewtopic.php?t=13826

What the msi package doesn't do right now:
Doesn't automatically install the DVD Player if needed. It is a pre-requisite to installing the msi, but will download it for you.

Thank you for the suggestion. I had my database backed up and made sure to restore it after confirming fullscreen was working.

Fantastic! I'm very glad that workaround worked for you!

Sure, you can delete it like any other program using the regular Add or remove programs menu.

The 8.8.5 installer embeds the Windows DVD player .msi and automatically installs it for you. If you didn't see any message in the console, it's simply because it was already installed
