Hello,
I am revisiting a MAME build I never fully realized. Initially I was connecting an old laptop that had VGA out to a Makvision M2929D4G-TS CRT monitor. This worked without issues running at 800x600 resolution at 60Hz. However I am now trying to replace this laptop in my build with an old gaming desktop for performance reasons. I'm encountering issues getting the desktop to send a usable signal to the CRT. The desktop has two EVGA GTX 570 HD connected via SLI and the machine is running windows 7 with latest video drivers and updates. These video cards do not have VGA out but I purchased
this cable which I assumed could step down the DVI signal to VGA. Windows detects the CRT as a Generic Monitor and says the native revolution is 1024x768, which I believe is incorrect. However, no matter what resolution, or refresh rate I select, I cant seem to send a signal to the Makvision CRT that it accepts. I have tried enabling/disabling SLI, having the CRT plugged into one gpu and my test lcd monitor(so I can see whats going on) into a different card or having just the CRT connected to the PC after a restart hoping windows would output the correct resolution.
Any ideas what I could be doing wrong or what the bottleneck in hardware/software is?
Thank you
