This "dark" appearance is the same for all videos (internet-wise, or personal videos) and on all players (WMP, Real, Jetaudio...). The only time the video looks "decent" is when the following window is open: NVIDIA control panel-->video & televison--> adjust video color settings. Even then, no matter how extreme i adjust the settings here, the video does not change from its initial "decent" look. if i play a video while this window is closed, the video resets back to its "dark" setting.
I've uninstalled and reinstalled the NVIDIA driver, but the situation is the same. I need some advise, thanks.
