It is a greatly mis-understood spec for sure.

There are elements in the OP that seem to be under-rated as well, like the reflectivity of the screen. That is more important to me than black levels because I don't watch much dark TV and when those scenes do come on I hate watching myself watch TV.

THANK YOU!!!

I agree completely. The only exception I would say is comparing the same brand during the same year. I wish they would just stop putting out that spec.

Another good read about contrast ratios and some of the tricks to measure bogus numbers that could not be seen with real content on the screen:

You can't completely ignore them though.

For example the Panasonic s2 is 2m:1, while the G25 is 5m:1...

And obviously the G25 has a more contrasy, just better overall pq.

But is it 2.5x the contrast? I doubt it, but NEITHER of these nor any other mfg CR numbers are anywhere near accurate. They are exaggerated by several digits which is a lot to be off.

All contrast ratio numbers should really come from a third party source for all TV's. Something like consumers reports or similar could to the testing. That way there is no desire to try an out do the competitors numbers just to sell their TV.

The other option would be able to make laws that prevented manufactures from using bogus data and variables in their equations to calculate real contrast ratio. Come up with two or three ways to essentially arrive at the same thing and let manufactures pick which one they want to use on their spec sheet. I know it will never happen but it doesn't hurt to dream.

I agree. It is amazing the same gov't that wants to control so much has not done anything about these bogus spec numbers for contrast ratios.
