The stock settings are waaaaaaaaay to bright. I don't understand and I can't imagine how someone could possibly tollerate it! Especially at sRGB.
With a DVI link, I'm using 9300K, With the brightness turned down quite a bit. Also, I'm using a gamma of 88 and the brightness of 98% on the nVidia display settings. Even so, the monitor seems still quite bright, but tollerable. I guess I'm just not used to a LCD, ccomming from an incredibly dark CRT.
