Upgraded Windows 7 graphics driver (out-of-the-box driver worked great except it had no OpenGL support).
Now that I've got the newer driver (Intel) installed, everything looks muted. Whites are not quite as white, colors are slightly muted, less rich/vibrant (desaturated?). Almost as if the LCD brightness had been turned down a notch. (In fact, that's what I thought had happened at first!)
Neither gamma, brightess, contrast or temperature seem to be able to bring it back to what it was. Is there something else I should check? LCD brightness is still set to 100%...
