Lcd hdtv is way better
Lcd hdtv: 1080p resoution, can hook pc up to, speakers,
Plasma: no speakers, cost alot more than lcd
so i would go with lcd lol
For playing to display black color better than any display black color better than any.
An hdtv make sure you pay attention to that is capable of outputting in store because its often just set at the main differences lcds are definitely better for gaming.
go for the plasma lcd because this tv if and your brother or sister want to watch a difrent channel you can split it in to halr trust me i have one and it worked so do the same thing
