im trying to run maximus arcade
On my Naomi universal
SanwA 29e31s 31khz vga

Lowest res I can choose is 800x600?
What’s going on?
I’m trying to configure the res on an Eizo lcd ..

Just found this

Display Properties > Settings > Advanced > Adaptor and click on the List all modes button. 640 x 480 should be shown - click on it and OK out.

Will try shortly hopefully this sorts it

You have to use a program like quickrez to set xp to 640*480.

I got it set 640x480 at 60hz

Not sure if I need to set the 60 hz ?
To the 31khz ?

60hz is vertical refresh, 31khz is horizontal so you don't need to set it as it's 640*480 horizontal refresh rate.

I’m off to connect it in a bit …
I have gone with lowest 60hz as I don’t want to blow a transistor with to high a Rez

Came straight on
I noticed through my phone cam
Refresh rate seems fast ..
Not sure if
