TV resolution?

Question

http://www.bestbuy.com/site/olspage.jsp?skuId=8742818&productCategoryId=abcat0101001&type=product&tab=2&id=1202648987833#productdetail I was looking to buy that TV and it says it resolution is 720p. It also says that it has HDMI ports. So when I use the HDMI ports do they become 1080p? What do they do?

Answer 1

This HDTV always displays a 720p picture. That's how it was manufactured. That is what "native resolution" means.

If you feed it a 1080p signal through the HDMI port, the TV just converts it to 720p (throwing away the extra picture information).

With only a 32" screen you are not going to see much difference between 720p and 1080p. Now if you were buying a 50" screen, you probably would see a difference between the two if you sat close enough to the HDTV and have good vision.

If you feed this HDTV a 480i signal, the HDTV will upconvert it to 720p buy "guessing" at what the missing picture information is.

The HDMI ports are where you connect hi-def video signals from things like Blu-ray players and HD- cable boxes.

If you get HD signals with an antenna or "open" QAM cable system, you don't need a HDMI cable. You just connect those to the cable/antenna "F" connector and the HDTV uses it's internal tuner.

Answer 2

If you buy that tv and are just going to watch cable it will be fine.  Cable broadcasts at 1080i,  which that tv will be capable of.  Unless you are getting a blu ray player you are not going to be using 1080p.
