i just bought a new monitor a viewsonic vx2255wmb and maybe 1-2 days after any movie or video doesnt playback on any player, just audio is all i get, i use this mainly for gaming and that works fine but i also have a lot of movies that i watch on here as well and i cant get them to playback, ive tried re intalling the monitor driver, video driver and such but to no avail. so anything i may have missed?
