Title: Alternative to adjusting screen pots per game?
Post by: tonyt76 on September 01, 2019, 09:26:42 pm

Hey guys,

Is there an alternative to adjusting the monitor screen pots for each game to fit the screen?

It's done per-resolution, rather than per-game, and there are ways to speed things up...

Go into ArcadeOSD and adjust the horizontal front and back porches. You cannot do this to any mode in the EDID, and on Win10 your ArcadeOSD might have problems with low dot clocks (i.e 320x240@60 modes or close to) but super resolutions should work fine. Once you get a particular mode looking right, remember to save it in ArcadeOSD, and add the updated horizontal timings to your mame.ini file - MAME uses the timings in the monitor range lines in that file, not the ones saved in the system by ArcadeOSD. (Or you can set up your resolutions with VMM again, with corrected timings).

Vertical size and position is trickier.

Or the guide here covers some of this, but is very long-winded - https://www.aussiearcade.com/showthread.php/87668-A-guide-to-connecting-your-Windows-PC-to-an-SD-CRT-TV-PVM-or-Arcade-Monitor
