What would you recomend a 46 inch Samsung LCD or a 40 inch Sony LED?
Also im looking for a tv for gaming, is 50hz noticable comapared to 100hz when gamin?
To clarify, LED TVs are LCD TVs - but just with LED backlighting, which promises (and often delivers) deeper blacks, faster response times and greater power efficiency.
At that screen size, also don't rule out plasmas - yes, they use more power, but have ultra-fast response rates great for gaming.
Any decent dealer should be able to offer you a demo with a games console so you can find a set that suits. If they don't offer it, take your console and a favourite game in with you.
