Title: lost resolutions after switching to DVI
Post by: gcpowers on December 11, 2015, 11:32:04 pm

I had been having trouble getting the 640x480 resolution to stick after reboot. after a search I saw Calamity had mentioned using the DVI out with a VGA adapter sometimes fixes this problem. I tried it out and sure enough that problem was solved! Unfortunately I seem to have broken something else as games no longer start at all because the correct resolution can no longer be found. This is running with a JPAC in a Vertical Cocktail cabinet. Here is the error log from an attempt to run Galaxian.

Thanks to Calamity for this awesome solution. It was so cool when it worked and I'm no so close to getting this project finished!!  ;D

might have something to do with your config files now having \\Display1 in them.

By switching to the other connector and using the DVI-VGA adapter maybe the system thinks this is a different display.

Might be worth checking.

Hi gcpowers,

Please make sure to check this thread (http://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=259).

Basically, there are two issues going on:

- Interlaced modes are being hidden by the system.
- All modes above 1600x1200 are being hidden too (2560x modes)

Both problems are due to the monitor not being detected. To get interlaced modes back you need to go to Advanced Setup-> Monitor, and uncheck the box "Hide modes that can not be displayed on this monitor".

Unfortunately super resolutions won't show either with this method. The work around we use is to redefine the super resolutions as 1600x instead of 2560x in ReslList.txt.

Finally, you must have a typo in your mame.ini:

-resolution value not available: 0x2560

You should have written 2560x0 instead of 0x2560. Now it should be 1600x0 however.

Thanks Calamity, ill check it out and see if this corrects the problem. I thought the 0x2560 was correct for a vertical monitor.

Calamity to the rescue. You rock my friend!

The hide modes box was already unchecked so i didn't need to change that. I made the other changes you suggested and that did solve the problem!!!

THANKS AGAIN!
