Hi,

I am using the Minimig core on a Gigabyte G27Q monitor (2560x1440 144Hz), which plays nicely with almost all cores in vsync_adjust=2 mode.

With the Minimig core vsync_adjust=2 the screens syncs, but i get a black screen from the core (monitor is synced), for example when loading MegaAGS.
If I set vsync_adjust=1, MegaAGS loads fine, but I get a mismatching refresh rate:
-On MegaAGS Menu:
660x216 15.63khz 59.4Hz
1920x1440 183.39Mhz 46.9Hz
-When playing a PAL game:
330x270 15.63Khz 49.9Hz
1920x1440 149.77 48.3Hz

Why is there a mismatch in refresh rates when using vsync_adjust=1? And is there a way to solve it?

As expected with vsync_adjust=0, I get a scaled output refresh rate of 50Hz.

Thank you in advance!

Problem solved by myself:
Commenting video_mode_ntsc and video_mode_pal in my mister.ini solved the problem.
Getting perfect 49.9Khz on minimig.
