My Viewsonic 775 has 14 out of the 15 pins too, so I doubt that's it. If only you had told what video card you have, maybe I would have pointed to video card drivers that could offer a way to brighten the output.
Okay I bartered to get someone to build me a computer. The only problem is that my viewsonic E773 monitor is rather dark. I turned up the contrast and brightness, yet it's still dark. I came to find out that the 15 pin cable that goes into the tower only has 14 pins. So is there a way to fix this, or do I need to buy an entirely new monitor?
please excuse my computer ignorance.
