Hi,
I didnīt solve the issue but will give it a new try with some new approach and info.
So my graphics card has 1 dvi, 1 hdmi, 1 display port. I figured that analog signal must come from the dvi port. I hooked up a dvi to vga cable.
I have installed the latest crm emu driver (crimson) for win 10 successfully and vmmaker. When I choose a 15,7khz res (on my lcd) the monitor goes out of signal and when I hook it up
to the scart/vga adapter (umsa) it still flickers. Itīs better than the picture but clearly out of sync. I bought at cheap scart/vga adapter from china and when I hook it upp it works using for example 800x600, 1024x768 at 60hz but this was only for test purpose..
What is the best approach to trouble shoot?
1) A cable issue? either the vga/dvi cable or the scart cable (has full pins and works in other configurations). The cables are working but perhaps not with this tv? Or should I try the hdmi port instead of the dvi?
2) Graphics card, should I try another one?
3) Television has problem accepting the signal? (for the record. I have an original modded xbox with mame connected via component/scart and it looks really nice)
4) Something else??
Would really appreciate if someone could help me solve this mystery and I can move on some playing at 15khz
