Look only at 1080p sets.
Figure out what size you really need (for larger) and/or can live with (for smaller).
They need to have at least two HDMI inputs (one for BluRay or DVD connection, one for later).
If it’s important to you to hook your existing and future computers to it (and you live alone, or your kids have a game system), you may want a third HDMI and/or a DVI and/or a VGA connector.
Go to a store with a lot of brands.
Let your eyes decide, and make sure you examine the leading models on your list in several different stores (sets are not always getting a strong signal, other glitches).
Then purchase based on price.
The Samsungs appear to me to be the best smaller sets when examined side by side with other brands (I bought a Vizio).
