Hi again, I searched everywhere but I can't seem to find the low impedance jumper, can you help me on this one? Thanks a lot! ;D

I plugged the VGA cable from the pc and everything went well, the image is sharper than before, I executed vmmaker and I got 80 resolutions but I can't seem to find one that works flawless. Even when I choose one and adapt the screen when I open a game the picture is off the borders, a lot!

GM does not read your adjustments from Arcade_OSD, it reads everything from mame.ini (either the -monitor preset or the crt_range# options). You need to manually port the adjustments in Arcade_OSD to crt_range lines.

I think I'm on something here  ;D When I put on mame.ini the arcade_25 preset the picture looks great but when I open the emulator it gives me a warning "SwitchRes: could not find a video mode that meets your specs" when I click ok the game opens and the picture seems ok, is something wrong with the config?

Thank you for your patience! :applaud:

It's just that you picked the 25 kHz preset, and because you don't have any 25 kHz resolution available in the system (you didn't create those with vmmaker) then GM turns -switchres off and you're running everything on the default desktop's resolution, with hardware stretching, it just seems ok to you because probably you haven't seen the real thing working  ;)

BTW, before you break your monitor, please make a research to find the working ranges of that model, I still don't know if your monitor is dual-sync, tri-sync, etc.

So it is better to use a 15Khz preset? I've read that only a few games work with 25Khz resolution. I'm trying to get the specs of my monitor to better understand it's limits  ;D

From what I gathered my monitor is 15-25 khz, by the way, when I turn on the pc the windows boot screen looks flawless, maybe if I try that resolution things work better?
Can't I use a 25khz resolution for the desktop and the frontend and 15khz resolutions for the games/emulator? Or is it going to affect the picture geometry?

I contacted a Hantarex technician and is answer was this: "the chassis is tri sync - but it only supports 640x480  and 800x600 res - normally anything higher then 800x600 will cause a split image on the screen"

Thanks again for your patience, I'm a noob on this sort of things :)
