Default 720p...1080i...1080p...???

Alright guys, need a little help here. After a couple years with my current 32" LCD HDTV, we're ready to upsize. And since we'll probably do it very soon (either day after Thanksgiving sales or soon after that with the Curcuit City close out sales), I need to find something out.

Why the heck am I seeing SO many new, high quality, big name brand, high price, HDTV's with 720p resolution? Like I said, its been a couple years since we got ours, but last time I checked, 1080i and 1080p were the best out there. But now, as I search the early 'black friday' ads, I'm struggling to find any TVs with anything other than 720p. And I don't see 1080p until you start getting up into the 50"+ range. Its like 1080i has just disappeared off the map?

After a quick search for answers, and a visit to a couple sites, it seems that some groups(like TV networks) pick 720p or 1080i for their HD broadcast, for different reasons. But never saying one is neccesarily "better" than the other.

So whats the deal here? I consider myself a pretty good tech head, but this s*** is giving me a headache. Is one better than the other or not?

My main concerns are that I have a PS3 that I connect to my TV with HDMI cable and I don't want my new TV to limit how good the blu-ray movies and PS3 games can look. Right now, the 32" LCD HDTV that I have is 1080i and I've been happy with it, so should I stick with that or 1080p, or is there a reason all these big name companies are pushing 720p units all of a sudden?

Thanks in advance.

(http://www.nurple.com/home-theater/1080p.html)

Can you tell the difference between 1080i and 1080p? The difference in the way the picture is scanned and displayed on your HDTV set. The i is for interlaced and the p is for progressive.

The difference is that with interlaced 1080i picture you see is scanned to the screen in alternating lines, so your HDTV will only get half of the lines of the picture in the first scan and the second half of lines in the second scan. This all happens so quickly that human eye is tricked into seeing a complete picture.

1080p Progressive scan differs to this in that it scans all the lines at once, thus giving a clearer and flicker-free picture. 1080p televisions display twice as many lines of resolution at one time.


In theory a progressive scan 1080p is superior to interlaced scan 1080i. But most HDTV's like LCD TVs and Plasmas TVs can't physically display an interlaced picture... so what they actually do when when using an interlaced picture it is de-interlaced and convert it into a progressive scan picture! So the argument goes that there is no difference between 1080i and 1080p because your HDTV will convert the 1080i signal into a signal all through your HDMI cables

But complications with de-interlacing cause problems, some TVs don't do it correctly and you can end up with less resolution than you started with. The TV's refresh rate also help determine the quality of the HDTV. HD-DVD or Blu-ray Disc players are currently the only device on the market that supports a full 1080p. Current digital television broadcast systems and standards are not equipped for 1080p transmissions... they broadcast HDTV in 1080i.

The resolution of 1080p televisions have the sharpest and smoothest images possible. If you thought HDTV looked good before... You will be blow away with a 1080p television. And with a 1080p TV, you can take full advantage of the new DVD formats: HD-DVD and Blu-ray.

We recommend buying a 1080p ready HDTV. But remember one thing... don't ever believe the hype. It all comes down to what looks the best to your eyes.. So do the research online.. then get your ass out there to your local HDTV retailer and check out all your HDTV options.

in short : 1080p is better. 1080i TVs just convert a 1080i signal into a makeshift 1080p signal to make it look better.

I got a 52" rear Projection TV (Mitsubishi) that is 1080i, looks great....paid 800$ at Sears for it. I wanted a Plasma for my wall, but the wife argued we already had this huge entertainment center that fits the 'older' projections, so i went with it...

Thanks for the answers guys. I think I found a nice 1080p that I'll be getting up at 4am tomorrow morning to go get. Hope I don't have to punch any old ladies out my way to get to it...those 'black friday' shopping crowds can be ruthless!

pff, it costs more than the price of the TV to get rid of a plasma because of all the heavy metals and sh*t.

I am going to be in the market for a new TV shortly; I have a fully digital setup with HDMI ready DVR and PS3.....the only bottleneck IS the 61" tv!!! Picture quality is still great, but I want full performance....

FWIW... You've probably seen a lot of commercials lately for Dish Network's "new" Turbo HD package. The Turbo package is different than a "standard" HD package in that it is broadcast in a true 1080P Res. Might be worth looking into. As I understand, Dish is currently the only provider offering a true 1080P broadcast.

Why..the only advantage to the plasma is its thin..It has an inferior picture when compared to a DLP rear projection..
