Perhaps, but if you're buying a tv and you don't know the answer to that question before you even think about visiting a shop, then you either don't care about it at all, or didn't do the research in which case you probably don't care about it.
I know when I bought my ES8000 back when it first came out I knew pretty much every little detail before I even went to look at it (along with the details of a few other backup options.)
Eh? I've just said that specs wont reveal what the panel is actually doing in 1080p24hz mode. Everyone here is assuming it doesn't actually refresh at 24hz, based on their own opinion thats impossible, but as the spec sheet nor the display says anything other than its in 24hz mode you'd never know what its operating at. The only spec you're interested in is if it can do natively 1080p24.
