Hi

I bought a Sony 32W4000 and i am a bit concerned about the gamma its sitting about 2.1 my question to you guys is should i be concerned or am i being overly paranoid

thanks

Likely doubtful that you would see much difference on moving images. 2.1 ... 2.2 ...

Gees, was that purse a bit brighter than it should have been?

That gamma is better than the majority of other LCD displays out there. Many show a gamma in the 1.9 range, with dips and bumps in the gamma curve. The difference between your gamma and a perfect 2.2 would be tiny.

OK, I have to ask then, how bad is 1.9, as long as it's a flat 1.9?

IMO not too bad- I know some displays like that which look pretty good- but maybe a bit washed out with highlight detail (not resolution detail) slightly blended together. By that I mean things like cheekbone shadows on faces, which could gain a slightly plasticy or clayface look, etc. It is caused by there not being as much difference in luminance between, say a 50% intensity image and a 100% intensity image as there should be.

Thanks Chad.

Is there a general rule of thumb for the eye's sensitivity to gamma deviation? i.e. What's the smallest gamma variation that can be perceived to affect PQ?

I think those are actually quite low, since 2.2 is lowish already. It is noticeable compared to a more correct 2.4-2.5 gama.
