So for some reason the bar with the possible resolutions is completely blank and cliking it won't do anything. What do I do?

You can set the resolution in the DeusEx.ini file in the system folder. Find and edit the lines that start
FullscreenViewportX=
FullscreenViewportY=
They should be in the [WinDrv.WindowsClient] section. If this doesn't do it, set the file to read only so the game doesn't change anything.

My experience is with Steam, so I can only provide you information regarding DX when it's run through Steam.
If you want to run DX GOTY in any screen resolution whatsoever, let's say 1024x768, try following these steps:

1. Set your screen resolution to 1024x768;
2. Try downloading and installing the Deus Exe Launcher;
3. Run DX through Steam and click "Configure";
4. Under "Viewport", select "Fullscreen" (DO NOT select "Borderless fullscreen window");
5. Under "Resolution", select "Common", choose "1024x768", then click "OK";
6. Click "Play" and it should work!

Let me know how it goes!

This is a joke. I have this game in CD with same version. When install from CD everything is fine. I think so 1 euro? Why not? Digital rack is the future, but this was a bad idea. I go back to the optic driver, take in the CD and instal the game, like in the past 20 years.

Dear GOG pls. fix this problem.

Just install kentie launcher: http://kentie.net/article/dxguide/index.htm

Compatibility mode helps.

The GMDX mod fixes all the resolution issues and works great with DX10.
What a great mod.
