The only way possible to get true 1080p is through BluRay. There is no other way right now. I worked for Comcast and was a specialist in the matter of HDTV. The companies advertise that they have 1080p but its not true, it is just signal that has been upconverted to 1080p but its not real 1080p. Most of the other "HD" channels are just digital signals upconverted to look like 1080i or 720p. There are a hanfull of them that are true HD. Just turn to HD Discovery and then turn to one of those "HD" channels and you will see the difference. All TV's need to be tuned professionally either by yourself or by a technician. They sell dvd's that help you tune them. They are exactly like our cars ( they are awesome stock, but a whole other animal when tune PROPERLY). Dont fall in to the whole HD hype on the tv's. Get a good brand (most of them are capable of 1080p nowadays), also 120hz will be more than enough. All that mumbo jumbo is not even visible to the human eye, its just numbers to bait you in. I have worked on MANY MANY MANY HDTV's and done 100's of installations, ive seen every brand known to man and ill list them in order from best to worst from by experiences with them. All Flat panels of course. (LCD, Plasma, and LED).
1. Samsung (good price, very reliable, great picture)
2. Sony (a little higher priced, extremely reliable, great picture)
3. Panasonic (beleive it or not, the were the best a few years back when they first came out, they have kind of slacked lately, but still very good)
4. Vizio (inexpensive, decent picture, extremely reliable, underestimated)
5. LG (average on all aspects, i have seen a number of them broken within a few years)
6. Phillips (ive seen a lot of these broken, they have power supply issues and the screens suck)
If you have no limits on what you spend, there are 2 brands that are in their own league. These things are hands down the best money can buy:
1. Fujitsu
2. Pioneer
Everyone will have there own opinion on this, but im just speaking from experience. I hope this helps.
