Please explain resolutions to me (arcade mon)

[hnugz]

I had everything working under winxp on my pc monitor, everything looked great.  I changed the windows boot up screen as well as the welcome screen.  Then I hooked it up to my arcade monitor using the arcadevga.  After the first boot, everything seemed about right.  Picture was a little off as far as bleeding but a small tweak of brightness/gamma fixed that.  Everything was running at 640x480.

Then I ran into the problem of loading mamewah and games.  They all started scrolling like mad.  Thanks to Harry Potter in my thread in the monitor forum, I was able to fix this issue by simply adjusting the v-hold or whatever on the monitor.  Now my games started looking good but windows was a bit screwy.  So I changed the resolution of windows to 640x288.  So now, windows looks good, mamewah looks good, and most games look good.  I used the avres tool or whatever to change the resolutions.

But not all games work, it seems like it is mostly older games like donkey kong.  On one of the games I just went in and changed the resolution in the ini file to 640x288 and it seemed to work fine now.

Also, when windows boots, the resolution is not 640x288, so the screen scrolls like crazy again.  Some parts of the POST look fine, but the windows load screen scrolls and the windows welcome screen is completey distorted.

So help me understand this, should I just go in and change any game that scrolls to the 640x288 resolution?  Or is there an easier way?  Why weren't they all just set to 640x288 in the first place?

Also, from all the threads I've seen in the search, they say you need to find a common middle ground for everything to work but they all say use 640x288.  How can I get the windows boot up to look normal as well as have everything else work?  It seems like I can only have one or the other.  Thanks.

The windows scrolling thing should just be a matter of making tiny adjustments to the vhold pot until you find the exact spot where windows and your games both display a stable picture.

so in theory there should be no scrolling between the 640x480 and 640x288 as long as the vhold is positioned exactly right?

Thats what I did with mine.
