    This contains an explanation of the problems associated with PC display systems with regard to gamma.

    Annoyingly the YUY2 overlays used by DVD's and DScaler don't take the same route through the graphics cards and so any adjustmets based on bitmap calibration patterns will not effect video.

    True but at the very least it will give you an indication as to what the overall system gamma is for your set-up: I luckily found out that in my nvidia drivers if I set the desktop display properties and save it as a set-up it also saves the overlay settings that were set at the same time: I'm also pretty sure the brightness control in my overlay settings is a gamma control. Twaeking them with ref to VE has now given me a decent dvd picture ( blacks detailed not flat and whites look healthy without being clipped and over bright : now if I can just persuade iiyama to give me the access code the the RGB bias and gain controls I can sort out me grayscale.
