Radeon HD 2400 - Multiple resolutions in game ini?

<< < (3/5) > >>

Calamity:
You may need to tweak your vertical frequency potenciometer a little bit. mk runs at 54 Hz, so it may be too low for your monitor settings. On the other hand, the modeline you're testing in Arcade_OSD works at 57 Hz, which may fall within your settings.

I have a real NBA Jam PCB and that works on this monitor fine, though again is a mess in groovymame. In fact I've never had a board not sync on this monitor (Nanao MS9).

Also World Rally was doing this before I upped the dotclock.

retrorepair:
There's no vertical hold on an MS9 btw

Calamity:
Ok so it must be something else.

So better try setting a higher minimal dotclock. Don't be afraid to use 8.0 or even higher. Most lower resolutions will disappear and be scaled by 2. Hopefully that should fix it.

retrorepair:
8.5 did it  :cheers:

Thanks Calamity!
