No problem. You can use 2.2 or 2.5. I get better results setting Gamma at 2.0 with My Panasonic TH-50PHD8UK and the Toshiba HD-A1 HD-DVD Player.
Just don't use S-Curve or you'll get "Clay Face" with some sources.

Here's a good explanation about Gamma by Gregg Loewen (Posted at Home Theater Spot Forum):
" Gamma refers to the amount of light output at any given IRE step. 0 IRE should have zero light output, 10 IRE should have x amount more than 0 IRE, 20 IRE should have x amount more than 10. Etc. Over the entire gray scale ramp, the light output can then be graphed / measured and a # derived. The graph should NEVER have an s in it but rather a nice upward sloping curve.
Gamma on a crt tube set is 2.2. This is what ALL DVDs and television material is designed for. Some video philes (ie: Joe Kane) have suggested that on digital displays the gamma should be closer to 2.5. As this will keep blacks darkers for longer and help perceived black levels on displays that have problems displaying black.
An S gamma over drives the middle of the gray scale range and makes the reproduction in accurate.
If you dont know what I mean by gamma curves, send me an email at
gregg@lionav.com and I will send you a couple of jpgs. Please do not respond to this PM, please respond to the listed email.
