Topic: ATOM-15 seems to cause issue with Dual-Monitor Setting
I already posted this question in the arcadecontrols forum and I hope it is ok if I give it a second try in this forum which seems to be the better place for such questions. I will also try to give more details here.
Here's my Problem with ATOM-15:
In my cabinet I use to screens. One CRT as the main screen and one LCD as a dynamic Marquee. With an ArcadeVGA5000 it just worked well.
Then I switched to a Sapphire Radeon HD 6450 GPU with CRT EMU-Driver and this also worked well.
Finally I flashed the bios of the GPU with Atom-15. When booting the PC with only the CRT connected, there is no problem.
However, when I have the second screen connected (LCD-Screen used as as dynamic marquee) the CRT seems to loos the signal after the first seconds of booting. There will be no picture and I do not know, if it continues booting and running windows. The Windows bootscreen won't appear.
When I unplug the second screen and restart, it works again. After everything is loaded, I can plug in the second screen and the dual monitor setting works.
Any help will be highly appreciated.
