Title: monitor 28'' crt with hantarex polo problem
Post by: diablo13 on May 26, 2013, 11:10:34 pm

I am new and i restore a multigame to mame cabinet. I keep the hantarex polo chassis with the default monitor. I use a pc with vga ati 9100 agp and from vga i connected the red green  blue ground horizontal and vertical. The problem is that the monitor shows the left screen of bios in the middle of the screen as you see in the below pictures

I moved the horizontal position to the end but the image still starts in the middle.
Any suggestions?
Thank you

You'll have to output 15khz. Either use soft 15khz or crt emu driver. You'll only have a stable screen in Windows then, though. The only card that can output 15khz while booting is the arcade VGA.

I think there must be a problem in some of the IC of your monitor.
