Forcing 15KHz on boot?

It's not really a video clock problem though :/ just a problem with which resolution windows uses on boot.

Also, i tried uninstalling soft 15KHz, rebooting, re-installing, same thing.

How are you changing it back to 15khz with an LCD hooked up?  ???
You probably have a card (or drivers) that doesn't work fully with Soft15khz.  I had an ATI that wouldn't let me get rid of a few stubborn VGA resolutions (line doubled 320x240).  I'm guessing it's not successfully swapping out the progressive 640x480 with the interlaced one?

Bingo Ahofle! I just tested it out a bit more. Using qres i set up 2 batch files. One set it to 240x240 (known good with my monitor) and a second to set it to 640x480. The 240x240 resolution worked perfect every time, and the 640x480 kept coming up out of sync. Also, i made the mistake of letting MaLa specifically force my display to 640x480 and.... well that just complicated matters that much more.

Any time the computer is outputting an "out of range" signal on the lcd, i can see things fine on the cab, and vice-versa.

SOOooo... what can i do about this now? Please don't say swap video cards. :( It's an integrated video card!

Ugh... just when i thought we were making progress.

If I run quickres (not qres, the command line tool) and then click the icon and set it to 640x480 with the LCD hooked up, it puts it in to a proper 15KHz, and things look great! ...until i reset the computer, in which case it stays 640x480, but reverts to the default KHz (whatever that may be?)

When i set the resolution to 640x480 in any other means, it goes to the progressive mode, and the picture gets all screwy again. Guess i can't have a batch file auto-boot with that...

OK I'm confused.  You keep saying that when you set the monitor to 640x480 with the LCD hooked up, it's proper 15khz.  640x480 progressive runs at 31khz -- 640x480 interlaced runs at 15khz and you would not be able to view that on a normal LCD.  It's possible you may have two 640x480 (one interlaced and one progressive) and windows picks the progressive one.  Not sure there is much you can do about that.  You really need to remove it.

I hate to say it, but you most likely either need to try another graphics adapter (check the Soft15khz thread for compatible cards) or maybe try an older version of the drivers.  I had to go back to an older Catalyst driver for my card to properly swap out all the resolutions.  If you are dead set on not getting a new card, that would be my next step.  Also, maybe send SailorSat (Soft15khz creator, and member here) a PM and see if she has any ideas.
