So i just bought a 40EX500 recently and it's a really good tv can't deny that. But i'm gonna talk mostly about input lag and Wii. Anyways don't be surprised if you notice my english is bad...i'm french canadian, hoping you will understand me though. So yesterday i was playing demos on my ps3 on this tv(ex500) all day since i don't have any games yet, well just one which is SSF2HD.
So yeah the image quality was very impressive even in gamemode it was just less smooth since motionflow is turned off when gamemode is on. And i couldn't notice any input lag but that doesn't mean there aren't though because when i started to play 2 fighting games on my Wii that i have lot of experiences (smash brawl/melee) I could notice all my timing were wrong and just couldn't play properly to the point i just gave up. So i connected my Wii back to my CRT to see if it was only my imagination or whatsoever but no it wasn't at all i suddenly got good again. So that's mostly it, if you're a hardcore Wii gamer i wouldn't recommend this tv i'm afraid. Can't say for Ps3 yet since i can only notice lag on games i have experiences and i've never played Street Fighter before, well only when i was a 6 years old kid when i had my snes but i don't think that count

. So yeah i don't really know what Street Fighter high level play look like without lag i'm sorry you just cannot notice just by simply pressing buttons even on Wii but you notice something is wrong when you're playing with games you have experiences when you see all your timing is wrong and all.. Hoping someone will do input lag test really soon for ps3/hdmi though since i bought this tv just for my ps3 and i might return the tv really soon. hmm END.
Oh and in before if someone ask me if i was using component cable. Yes i did.
