Anyone know which games support borderless window mode, or how I can possible force it on certain games. I have my 1920x1080 monitor being used as a desktop and a older 17inch CRT beside it that I want to use to player some older games such as Arcanum of Steamworks and Fallout tactics. If anyone can help me out with this I would greatly appreciate it

As long as the game supports windowed mode, you can also use the tool WindowedBorderlessGaming.

The main problem with all borderless tools might be getting the games into windowed mode in the first place.
With Arcanum, you'll have to apply the community patch and the High Resolution Patch to adjust the window size later on.
Then edit the game's shortcut and add -window to the end of the target field.

The game might crash now until you remove/rename ddraw.dll in the game's installation folder. But you have to have all older components of DirectX9 properly installed on your system.

For games which don't offer windowed mode, you can try using DXWnd, a tool that redirects DirectX fullscreen output into a window.

With a bit of tweaking WindowedBorderlessGaming works fine with all DOSBox titles, as well. (Set DOSBox's Graphic mode to DDraw; PM me if you're experiencing any problems setting it up)

If you configure Windows to use the CRT as its primary display, fullscreen games will launch on that display. Then just change it back when you are done playing.
