I am looking to get a new 40in led lcd to replace my 7 year old Sharp Aquos LC-32GP2U. looking for a led in hopes that it will not get as hot as my current tv does. the tv can only be 21.8in tall without a stand, so it needs a thin bezel which seems to be standard on nearly all new tvs. I have a receiver and speakers so I only need 1 hdmi in, and I don't care about the speaker quality. I also have my PC hooked to my receiver, so I don't want a smart tv. And I don't realy care if it has 3d or not. I just want the best picture quality I can possibly get for around $500. the biggest problem I have with my current tv is the lack of detail in dark scenes, so fixing that is a must in the new tv. so far I have been considering the Samsung UN40FH6030, Sony R450A, and the Toshiba 39L2300U. recommendations and suggestions will be appreciated. thanks for the help.
