I just hooked up my new motherboard with a AGP slot capable of 4x speed. I bought a Trident video card with 4 MB, and is AGP 4x compatable. When I turned on my computer, however, my 17" monitor works, but is very, very dark. I could set the monitors options digitally on the very bright superimposed menu, so I no it isn't the controls or the monitor. Any suggestions for fixing this problem would be appriciated.
