Hello guys,
I have a problem with mario bros arcade game on my unico ulm26 display.
When i load mario bros, i have a black screen and " out of range " message...
Someone have any idea where problem is?
Thank you for advance for your help!!
Are you using HDMI or VGA? If it's HDMI you probably need to change vsync_adjust in the mister.ini to vsync_adjust=1 (or if that doesn't work vsync_adjust=0).
Even though these are sold as "arcade monitors" I've found they can be very finnicky with non-standard refresh rates over HDMI.
Can you run the update again? I updated the core again with a different build to try and address marginal timing issues potentially.
It fixed a similar problem for someone else.
Ok guys and thank you very much for your help 
If i setting vsync adjust=2 all is ok
Oh that's an arcade monitor drop-in replacement... no wonder. I was wondering why you were using vsync_adjust=2 for analog video
