Dark videos

So I had just reformatted my HDD and while trying to watch a video I noticed that it's VERY dark, almost a black screen.  Some of the videos will play fine and the audio for all of them will play fine.  I've tried using zoom player and WMP, I didn't have this problem before but I don't remember exactly what codecs I had installed.  Currently I have the combined community codec pack and an OGG codec installed.

Any pointers on what I'm missing?

fucking stupid pieces of shit
this haves nothing to do with the player or brightness or gamma theres and option called ""video overlay settings"" that only affects the player not the screen or anything else
find it by clicking right and properties on your video card options ,this question is so damn noob and stupid that its obvious a troll
