Need help with Win7 video display issue?
I like to output video to my TV via VGA from my laptop. Something is causing my "black level" of the image coming out of the laptop to fluctuate depending on overall brightness of the image on the screen. The phenomenon is duplicated on the laptop's screen as well. It isn't an issue with the TV. I want the black level to to be stable; not change; be "fixed". If you've ever calibrated a TV image with "black bars", you understand what I mean. Any ideas what's causing it? I had ATI Catalyst Control Center for the built-in ATI video adapter, but I didn't really use it, so I deleted it. I was able to stabilize the black level when I turned the Catalyst Control Center On, but it was a hassle to turn it on each time I powered the laptop up. Plus, I like to keep things as simple as possible. It seems as though something on this laptop is trying to control my black level, probably to "help" my viewing experience, but I want it to stop "helping" me I assume when I used to turn on the Catalyst, it took over whatever that feature was. I'd just like to turn that feature off without the Catalyst running.
thanks!
