Hello Calamity
Thank you so much for your help!
Let me try to resume to you what i did, just a note this is a patched 5450 with 15khz
1) First i boot with normal vga port with rgb modded tv
2) Them i turn on Teamviewer
3) Pluged the secondary rgb modded tv on dvi (vga adapater) tv was scramble
4) on notebook acess the computer remotely and start Vmmaker, assigned arcade15 for the non work tv.
5) them on Windows 7 desktop chosse to clone both output
6) Windows enviroment works perfect with both tvs
Now is the problem.
On first attemp ran Advmenuplus i like it workss windowed (strange), them running GM it works but kind no swithres working, like it was working with desktop resolution (640x480).
So i booted the system.
Again windows enviroment worked great, on second attemp, advmenuplus and gm worked normaly with correct resolution as it should but only on dvi port.
Vga output is black without any content, but when goes back to windows both displays working normaly.
That is where i´m stuck.
Maybe need to use that marquee solution force the vga port, display the content of the dvi ?
Any suggestion will be very apreciated.
Thanks a lot
Marcos
