I was thinking about buying a new TV, but i don't know the differences in HDTV's. I want a HDTV but what is the difference between built in HDTV, and HDTV ready. I don't want to add any adapters to my tv, to get my hdtv, i want it right out of the box, what is the best choice for me?

HDTV ready means it is capable of displaying the signals but needs the additional convertor/adapter piece. If you don't want an additional external piece get one with the HDTV tuner built in.

So if the tv says HDTV built in, is that the one i want?

Yes!!!

Wouldn't that be different if you had an HD receiver from a sat company? I thought a built in tuner was basically for OTA broadcasts.

You're correct. A built-in tuner is only necessary if you're planning on viewing OTA broadcasts. If you're getting your HD through cable or satellite, an HD-Ready TV will do just fine...you just need to get a converter box from your cable or satellite company.

I smart

"HDTV ready" originally meant that the tuner was built-in. Then you started seeing some companies use it to mean "HDTV compatible" (no tuner built-in) instead. What it means varies from manufacturer to manufacturer.

AFAIK all new HDTVs that were manufactured after a certain point were required to have the tuner built in, so most of what you see in stores now have the tuner built in.
