Maybe it's just me, but wasn't the 1292Q listed in the "high performance CRT projectors" section of the rankings?

http://www.curtpalme.com/Projector_Rankings.shtm

If it was then what caused it to be dethroned? Streaky picture issues? I see the G70 is listed in the high performance CRT projector section and I thought it wasn't capable of fully resolving 1080p. 8" tubes and almost 1080p is good enough to be considered a high performance CRT projector? Can you tell I own a 1292Q? Very Happy

I'll be the first to admit though, the streaks can be a pain in the ass. Maybe I just need to tweak my setup more to reduce their presence.

Yes, you're right: We moved a bunch of things around.

The following were moved from "High Performance" to "Intermediate Level":

Sony 1292
NEC 10PG
Barco 1200
Ampro 4200

The following were moved from "Intermediate Level" to "High Performance":

NEC XG
Sony G70
Barco Cine 8 Onyx / Zenith Pro 1200x

Nope. Just some of the higher end units that people tend to bitch about.... Wink

I have a 1292 , XG135LC , and a 9500 .

The only Bitch I have with the Sony is noise and streaking , otherwise its the best projector I have owned to date .
XG is no whisper machine either , and rather retarded . As I found , it needs constant attention and spoon feeding

Can't comment on my 9500 yet as it has more fungus in the C elements than a goldfish tank in a crack house Evil or Very Mad

What exactly determines a High Performance PJ? Is it the image or what?

The only reason the 4600 is still on the A-list is because of it's outstanding reliability Laughing

Apparently no one compared the NEC XG to the NEC 10PG, I used to have a XG and moved up to a 10PG. The 10PG is way sharper then the XG's. The other thing to consider is, sense the 10PG (and other 9" PJ's) have way more phosphor to work with, at the same brightness the tubes will last all most twice as long. A 8" tube probably has 20 square inches of usable phosphor, a 9" has like 35 square inches of usable phosphor. Not only that, blooming will occur sooner on smaller tubes and sharpness suffers way before blooming occurs on smaller tubes do to less phosphor. Of course, then again I can see these differences running a 160" screen Very Happy

All I can say about the other PJ's that do not have the "Awesome colors" the NEC's have is, I hope these people enjoy their orange red's and their yellow greens Mr. Green

Deron,

Your characterization of the tube sizes is way off. It doesn't matter that there's 20 vs. 35 sq inches (or whatever) because most of us are only using about the center half or so, and even less because of keystone. Set up a 9" machine on a 16:9 screen with some keystone, and you'll be using about 25% more phosphor than you would with an 8-incher - that's 25% max. In practice, it would be even less.

Using a more realistic number, if you'll get 8,000 hours out of your 9" tubes, I'll only get 6,000 out of mine. Obviously, it gives you some headroom to drive the projector not so hard, but you can easily run an 8"-er on a sane screen size to decent levels without blooming. Phosphor longevity - big whoop. How many of us will even have our CRT's (much less the SAME CRT) in 5 years?

As for your comparison and tiny sample size of two projectors, can you say your 10PG isn't better than most and is it possible that your XG wasn't up to snuff? Were you trying to light up the 160" screen with the XG? What lenses were you using - that's a big screen.

Jeez, even my lowly 12xx's have correct colors due to color filtering...

Do not twist my words please, I did not say, like you infer, that all PJ's do not have the awesome colors the NEC's have. I just like to poke fun at the PJ's that are rated better then the NEC's, that do not have correct colors.

And what's that supposed to mean? People have a better understanding nowadays of what makes a CRT PJ produce accurate colors. I'm sure the people that designed and built these CRT's knew now to get accurate colors. Some of them just choose lumen output over more accurate colors, which was a wise choice when building a PJ for boardrooms or control centers...

No, your wrong Very Happy

Size does matter 8)

I had several XG's, 1100, 1350, 75, a bunch of 8000's and 8500's, 1272... Dam, I forgot all the PJ's I've had over the years.

I found out that the 8" machines would not give me the sharpness I wanted on a super big screen. I spent a hell of a lot of time setting up several of them trying, maybe I could do better now, but when I installed the 9"er it was a done deal.

Oh, and by the way, do not let Curt know you will be offloading your CRT after five years Crying or Very sad

I've had my 10PG for like five years now, have a set of new NEC tubes, hopefully this thing will outlive me Very Happy
