What brand of tv is good to buy?

There can be no single answer to the "best" brand.

Before buying a television, set your size and budget range and then get to see as many models as you can. See what features each of them has and make your short list.

The model that you think has the best picture is probably the one you should buy. After all, you will spend a lot of hours watching it, so make sure you choose the one you enjoy most.
