hi, guys. So Iv'e just built a brand new computer and i've noticed that whenever i play videos, they appear very dark. i know for a fact that it this not a moniter problem. ive tried installing some codecs, but nothing has been working. also, i have no clue on how to adjust the settings on my video card if perhaps that is the case. i have a BFG GeForce 7900 GTX OC video card. any suggestions? any comments would be very much appreciated, thank you.
