After a windows update and updating my graphics card drivers, video playback became almost impossible. The video playback in all of my multimedia players was overlayed with a bright green filter.

A quick search through google and the nVidia forums and I fond the answer. The nVidia drivers are to blame, and the fix is simple, but temporary.

This does fix it so long as you don’t change the gamma settings back to Video Overlay or Desktop.

• Right-click on the desktop and select Properties.
• From the Display Properties select Settings.
• Click Advanced.
• Click on the GeForce tab (this will be your video card model… example.. GeForce 6800 Ultra)
• Click on Color Correction
• There should be a drop down menu top left with Desktop, Video Overlay, and All. Select All from the dropdown box this should set everything to driver default and click Apply. And your video overlay gamma should be fixed.

Please note: This is the only temporary fix that will work with everything and, depending on your system, you might find yourself adjusting it everytime you restart your computer.
