Default Questions about buying a used 57" CRT 720p

I am just getting starting learning about HDTV. I am definitely a budget limited buyer too. We have a very large living room and need a 57" set since the old projection TV is 54 or 56 inches. It'd be hard to go down in size after getting used to it. The old TV came with the house. The previous owners put a flat panel in their new house. Weight is not an issue, because we just bought a house and won't be moving for years and years.

So, I think that a projection CRT is the way to go for me. Since I have noticed sloppy looking pictures during football games (HD broadcasts) on other people's HDTV's, I'm sure I want 720p. I'd go 1080p, but there is NO way I could swing that kind of price.

I'm thinking that a lot of you have TV's that may be what I want. I won't be buying until January 2006, right after Christmas. I'm hoping that I can find someone that wants to buy a newer TV and sell me a deal on their old TV.

Do you think I could be making a mistake buying a used CRT 720p TV? I have NEVER had an old CRT TV crap out on me. The model I have selected so far is the Sony KDP-57WS655.

Well, for starters, I believe the Sony KDP-57WS655 has native resolution of 1080i. Virtually all CRTs do. So, while it could accept a 720p signal, it would convert it to the 1080i.

If you are strictly looking for 720p (which you probably should as a sports fan), you would be better off looking at RP LCDs and DLPs. Sony is the "leader" in LCDs (which I recommend) and Samsung with DLPs.

However, you probably won't be able to find one in the 60" size for cheap. If you do decided to go with a CRT, I wouldn't recommend a used one, mainly because of burn-in issues. Depending on how old the set is or how much and well it's been used, it may suffer from burn-in.

Crap... So if I want a good image for sports, I need to get a RP LCD or DLP huh? I didn't know about the 1080i CRT thing you mentioned. I had read that the CRT's don't really have a native resolution, just a maximum number of lines.

I'm going to research what you said. If you're right, it's back to the drawing board for me.

Thanks for you help.

No problem and good luck.

Generally speaking, a RP LCD or DLP in the 55-60" range would probably cost you about $3,000 new. However, that's the average retail price. Shopping around a bit or picking up a used one, should save you a few hundred dollars.

I'm sure others here will be able to back me up regarding the 1080i CRTs. I have only seen one CRT that was an actual 720p set (native resolution).

There was ONE company, Panny I think, that made a 720p CRT HDTV about 4-5 years ago, but no longer. It was $3500, 38"? There's one company, Monivision, that makes a multisync presentation monitor that can handle HDTV formats, including 720p... 34", $2500.

CRTs are limited in their resolution not only by the scanning frequencies of the electronics, but also by the mask pitch... although 'slot masks' like Trinitron only are restricted in the horizontal axis.

I don't think you should let the 720p vs. 1080i hang you up. Some stations broadcast in 1080i and some in 720p. So no matter what you buy it will not match what every broadcaster is sending you.

So, please rank the following in order of most likely best picture quality, the best first and so on.

A. 1080i sports broadcast shown on a 720p set that can accept a 1080i input

B. 1080i sports broadcast shown on a 1080i set

C. 720p sports broadcast shown on a 720p set

D. 720p sports broadcast shown on a 1080i set that can accept a 720p input

From what I've READ, not SEEN, here is how I'd rank them.
(best)C,B,A,D (not-best)

Please tell me what you think, and why.

From what I've read, the greater refresh rate of the 720p outshines the higher resolution of 1080i (in sports broadcasts only). That's why I was kind of locked into the idea of a 720p set.

Do any of you honestly think that an average TV viewer would notice the difference between a 1080i and 720p set anyway? I could have been wrong about the "sloppy" picture during the football game I watched. They may not have even tuned it to the HD channel. I didn't ask. I just assumed they had a clue.

Some people do notice a difference between a 720p set and a 1080i set if even placebo. The bigger point is there is more 1080i programming than there is 720p at the moment. The only time you would get the 60fps advantage would be watching sports on ABC and FOX plus ESPN if you get it in HD. Everybody else is using the 1080i format. Remember any material that is film based like movies and most network prime time shows are shot at 24fps, so 30fps of the 1080i is just as good as the 720p/60fps for this material.

What seems like a bigger concern for you is the price. CRTs will be cheaper, but I don't think I'd buy a used one myself. The DLP or LCD might be ok to buy used, but I'd be sure there are no dead pixels and you should realize replacement lamps can cost several hunderd dollars.

One thing is for sure. Both 720p and 1080i will look alot better than SD on any 57" TV. SD will look like crap and you'll cus it every time you watch a game in SD.

Are you saying that after I get an HDTV that I'll be pissed whenever a game I watch comes only as a standard broadcast, because it'll look so bad on an HD set?

Or

Are you saying that any game will look like crap on any standard 57" TV, period?

I can say that the picture IS crappy on the 54" standard projection dinosaur we have now. That's what's got me wanting an HDTV. The picture wasn't so bad on our 36" standard CRT in our old, smaller living room.

Standard def on HD sets, generally look worse (for various reasons).

Yes to both. SD on your 54" may look better then on a new 57" HD TV.

I think you might try a 50" EDTV from Panasonic for around $1700 at Costco. As far back as you are sitting the reduced resolution will not matter. SDTV will look much better as well because of the reduced pixel count.

Costco has an unlimited return policy, so no EW is needed maning if the TV fails in five years you can return it as long as you are comfortable doing so. They also carry other type and brands, including a 50" full HD Plasma for $2500. LCDs, DLPs........Worth a look

Watching HDTV spoils you for old analog SD... no sparkles, ghosts, and many times the detail.
