Hi there,
I got 3 CRTs quite some time ago, 2 PAL TV sets (so I need a DVI to SCART adaptor) and a Sony PVM monitor (here I need a DVI to BNC adaptor). I mainly used them to play with real consoles but, now, I'm trying to output emulators rendering to my CRTs. I've been told that GroovyMAME is one of the best solution to do it but it seems like it can only work with CRTs only if the computer is equipped with ATI/AMD graphic cards. Why can't it be done with Nvidia graphic cards?
I have a computer with a Intel i7-4790K 4 GHz, 16 GB of RAM and a Nvidia GeForce GTX 970 under Windows 10 64-bit.
