Does anyone here know the custom mode settings for MiSTer.ini needed to get 1920x1200@60 and 1600x1200@60 display modes working?

According to the DE10-Nano User Manual the UXGA (1600x1200) resolution is supported so I used http://www.epanorama.net/faq/vga2rgb/calc.html to get the correct parameters.

These settings:

video_mode=1,1600,64,192,304,1200,1,3,46,162

work fine with my Dell U2410 monitor. If you want ro try this mode use these settings at your on risk.

probably because buffer size 1600x1200 is less than 1920x1080. But this is anyway not supposed to be supported resolution. 162MHz is beyond maximum which is 148.5MHz.
If it works for you, then OK.
