I have been messing around with calibrating any TV I can get my hands on just to gain some experience.
I was working with a cheap 37" vizio. However it did have high and low rgb.

I was able to get something pretty decent except with one problem. To get near 2.2 gamma I had to sacrifice contrast to the point of the scene being rather dim for normal viewing.

Is this a common sacrifice that needs to be made either way(brightness or gamma) on cheaper LCDs?

Sorry about a basic question and I realize its hard to pinpoint anything specific with so little information. Just want to make sure I am not completely missing an aspect of calibrating.

Thanks.

While you've seen that contrast can interact with gamma, it's purpose is not to modify the gamma. It's just a by-product of the way contrast changes the overall light output.

If you don't have explicit gamma controls or a 10+ system, you simply get what you get.

Your best picture is going to be with contrast set correctly to the edge of clipping (at 255) that will maximize dynamic range and contrast ratio. Both of which are at least as important as overall gamma.
