I have a marquee screen that is 2560 x 1440p and a CRT main display that is 640 x 480.
When using the high resolution screen as my marquee and CRT as the main display, everything works as expected.
When using the high resolution screen as both my main display and marquee screen, this mostly works. What happens is, navigating the menus shows up just fine, when I select a game, the game shows up on the CRT screen, which is great!
The problem is, the high resolution screen simply goes black until the game ends.
I'd like to use my high resolution screen for navigation, then when selecting the game, have that same screen switch to marquee. Is this possible?
