Hey you guys have a great forum here.
I was hoping someone could shed some light on my problem.
I'm building a cocktail table which is almost finished with the exception of the video. I'm using an Ultimarc avga card and a WG U3100 monitor.
Everthing works fine more or less with a regular computer monitor hooked up.
But when I plugged the U3100 in, the screen looks like it's too long and the left
side extends back around to the right side of the screen. If I change the resolution, things get bigger or smaller but the wrap-around issue wont go away.
After fiddling with every pot on the monitor in an attempt to adjust the picture,
I tried plugging said WG U3100 into the upper (HDI) jack via an hdi-to-vga adapter.
Success!, at first.
But I can't go higher than 640x480 without getting
a scrambled picture. In addition to that, the majority of my roms
(pac man, galaxian) cause the picture to scramble until I hit escape.
A few work perfectly (Q-bert, Robocop) and some don't load at all.
So.....
What am I doing wrong?
Which plug should I use on the avga, the top(hdi) one or the
bottom(vga) one?
Is there anyone out there who has a cocktail-type setup with an avga and a U3100? Or any kind of setup with an avga card and a U3100? If so, what mame/frontend/etc are you using?
Am I better off going with advanced mame? What frontend is the best?
Do I need to use a resolution tool? If so, which one is the best?
Is there a good faq somewhere about hyrbid monitors? (that's what I have, right?) or some kind of documentation other than the circuit diagram that came with the monitor?
Any help would be most appreciated :notworthy:
and I promise I will pass said knowledge along to the next poor soul
I run into confronting similiar problems.
