Orion 29" 15khz Monitor

[wmanst]

Hi

I have just brought two cabs with theese monitors here is the model number A68KTB190X006 and chasis YTE HR293..Well i have several problems with them..

- When we tried original PCB with them vendetta and tekken 3 the picture seems fine bright and not overly saturated

-Than we hooked up mame box and the games seems so dark and not bright as usual also the color pallete was off..

-Not sure if it's related but when i pause the game it does not go dim or dark it just goes brighter ? Opposite effect but the screen is nicely bright as it should be ?

-There is brighteness pot in the controlls but it seems does not do anything

-Also when i hooked up ati 4800 series card it does not detect the monitor but before i have tested it on scart tv and set primary monitor on vga output Picture show on secondary dvi connector ??

-Not sure what to do now i have already brought them i have not tested before so is there anything i could do to improve image ?

Thanks
