with a random bunch of domestic tvs- thats more than just a mix curve-
there will be different gamma response on each one

For instance I currently have 9 domestic CRT tv's each with a mix feeding to them. When I spread an image over all of them and fade it up, the fade across all TVs is different.
Currently I'm having to use 9 layers set to "use layer mix" and set curves on each layer using my console.
If I was able to set a curve on the mix in catalyst this would make life easier.
can you put up a grey scale and colour chart on each tv - at full intensity
then take a decent photograph of each screen
this will give you some idea of the gamma differences
To take Richard's method a bit further, I will actually point a Flat camera at each screen/TV and then use a scope to adjust the settings of the media server output. This has worked wonders on LED walls, different video projectors, and anything else which might pop up.

...if it ain't broke...
gimme 5 and then don't act surprised

it needs a gamma curve for every mix-
i dont think intensity curve would work for the tvs - intensity curve presumes linear intensity across the colour output
