Kortek KT2914F not working on high resolutions!

[Topgun_68]

Not sure if people still monitor these forums but wanted to know if anyone ever encountered this issue. My arcade machine worked great until I moved and now I get a blinking box that says out of range when I power it up. I removed my arcade VGA video card and hooked it directly up to the PC and it used to work at 800 x 600 or better but now the same issue. I had it repaired a few years ago so I now it had a cap kit done. I tried resetting to defaults in the hidden system menu. Is this a hardware issue with the monitor or an possible adjustment? I did manage to change the refresh rate once and got it to come up. It works fine if I hook up a standard computer monitor to it.
 
Thanks for any info!

Try a different cable?
