I think I've narrowed my choice of telly down to either the Panasonic TXP42G20 or the Sony KDL40EX503.
Problem is, I want to use the set for gaming as much as watching telly so whichever one I pick, it has to have a low input lag.
The Sony appears to be the better set for the money, it's cheaper than the Panasonic and it has been internet-tv functionality (especially the Lovefilm service), it also won't suffer from the rising black level issue that the Panasonics are known to have. Unfortunately though, I've been unable to find any solid information on the input lag on the Sony when using the Wii or the PS3! None of the reviews I've read seem to mention it, which I find quite strange.
Does anyone own these sets and has any info that could help me?
