Well.....I finally got to hooking up a 1208s/2 I picked up two years ago and just installed it at my friends place. We started out with 720p using a pc. Then we ran it up to 1080p. It was ok but we were able to go higher. I thought these things maxed out at 1600x1200......read the documentation....2500x 2000.....could Curts projector ranking be wrong? It says 1600x1200 for the maxx on his list. However I think Curt was just saying try it if you must. He never said modd it. However back to beginning...so I thought ok why does it not look so sharp @1080p? Then I had my CNC man make some HD-145 lens adapters and wham!!! 1080P perfection. The HD-145 lenses are a kick ass combination with PT18-205 TUBES!!!! And all this time I was convinced to need a different unit for 1080p. And all this time it sat around along with a spare set of 145 lenses.

this is a really old argument, been debated to death really. there's one camp that say's an 8 inch will never do 1080P properly and another that say's it looks great, which of course it does. Neither opinion is wrong. My POV is somewhere in between, get yourself a good processor and scale 1080P down exactly 25% to 1440 x 810 (16:9 AR) and increase the scan rate to 72HZ.
Personally, I can't stand 1080i flicker and jailbars

I had no trouble with 1920 x 1080. I believe it is the model of tubes and the 145's in combination with each other. I tried others before with 145's and they make lower end tubes look good, but not to this extent.

1080p on the Dragan Dragon marquee is fine. A.little ringing on the side, cantt hardly notice it.

glad to hear it. The ringing can be an issue on any Marquee, it can be eliminated, or very nearly so, by adjusting porch sizes on the VP. Did Mr. Gannon mess with those at all?

We honestly ran outta time. It was midnight when he left, my wife was madder than a wet hornet at me for making her work. Haha. I was hoping someone would chime in with the porches. Ive been playing with the program Nash uses and the vp50.

It depends on the source and the Marquee. Some ring some do not. So different timings for different flavors. With the HDQ you'll be limited to 1080p@48hz. it can be done with 1080p@60 but it is a real pain because when you get close to the limit of the HDQ's bandwidth it blanks the picture over the digital outs. But if you have , lets say an HDCP stripper before the lumagen and go out the RGBHV's , then you have more bandwidth to work with.
For Blu Ray id use 800p@72. Maybe Justin(JBmeyer) can give you what he ended up with.

Nash.
I.followed your posts along with Justins. A lot of helpful tips. l am curntly running 817p72 for movies and 1080p60 for TV thru my.dvdo vp50.

I have 2 NECs, so i dont have those problems  ( infact it doesnt even flicker at 50Hz on 1080i )

what the heck does the projector have to do with it? 1080i flicker is 1080i flicker, and 540 scan lines painted in alternating fields every 30 seconds makes giant horizontal jail bars . A Marquee 8500 with 120Mhz electronics bandwidth can 100% fully resolve it and fully show how crappy it looks.
1080i 96HZ maybe but (sorry to say) 1080i 60 is

Relax mate, its a joke. Youll live im sure
1080i 50Hz and 60Hz look fine to me, although ive been running the PC at 1080i 120Hz with the XG for a fair while now. Why use 96Hz?
But every 30 seconds you paint an alternate field? Where do you get this horse sh** from? No wonder youre getting jail bars!! Ill stick to painting 900 fields every 30 seconds and stay out of jail

Ill just stick with 1080p being output from my VP to the PJ, and all other sources being upscaled to that, I am happy with it, and when watching a blu ray I can't beleive how awesome the PJ looks, and im not even seeing native 1080p from my devices.
I have no issues with 1080p on the NEC XG1101 it works damn good  and with my HD 145 lenses (or 144s, I dont remember anymore) it rocks.
Its a shame the Xbox 360 is such a POS as far as gaming graphics go, there is no Anti aliasing so it doesnt show off the true awesomeness games could look on the PJ.
WTG Digitalayon  Enjoy!!

I mis-spoke, alternating frames, not fields. Surprise you didn't just catch the implied meaning. Either way at 60hz it's the same effect and I can't watch it. If it works for you then that's great.

| Quote: | | The frame rate can be implied by the context, while the field rate is generally specified after the letter i, such as "1080i60". In this case 1080i60 refers to 60 fields per second. The European Broadcasting Union (EBU) prefers to use the resolution and frame rate (not field rate) separated by a slash, as in 1080i/30 and 1080i/25, likewise 480i/30 and 576i/25.[1] Resolutions of 1080i60 or 1080i50 often refers to 1080i/30 or 1080i/25 in EBU notation. |

I proved, a LONG time ago, that even a mere Marquee 8000 is fully capable of resolving BEYOND 1080p on the CRT faces. But the HD-8 (or 8B) lenses
are not quite good enough to fully resolve it.
When I did my original Frankenyoke experiments, I achieved clearly defined one on, one off pixel patterns with a respectable MTF value (by eye, not
measured as I lacked that equipment) with the resolution all the way up to 2048x2048 in 4x3 mode, which equates to 2048x1536 (QXGA mode) squeezed
to a 16:9 aspect ratio.
On an 8000. The corners weren't perfect, but central focus was so sharp it'd cut your eyeballs. Clearly, better lenses were needed, but there was nothing
wrong with the resolution potential of the projector or CRTs.
The biggest single reason why 9" machines are usually thought of as the ones that resolve higher resolutions is simply because both the CRT face and the lens
is larger, allowing a lower pixel density that is easier for the optics to resolve.
An HD-10 lens which is made to exactly the same quality standard as an HD-8 lens will be able to resolve 20 percent higher resolution, simply due to the
greater pixel spacing on the face of the larger CRT and the larger lens aperture.

What really suprises me is you actually thought i meant that... And it wasnt the frames or fields part im making the joke about, its the "every 30 seconds" part im questioning!!

Works perfectly fine on my XG too Jeremy, i just reckon it looks alot better on 1080i.

A year ago my friend replaced his low hour 9PG xtra with a late model Marquee 9000 (only VIM, neck boards, CVA, VDM were original, the rest was from a 9500) and he got worse 1080P results with the Marquee, than with the NEC, also I had a marquee 7500 at that time and it was also better than the 9000 in 1080p, I have to admit the scheimpfug wasn't on the top on the 9000 while testing, but after many-many tinkering it didn't get much better. An when we swapped the VIM and neck boards from the 7500 it got much better!

30 alternating frames every second as opposed to 60 or 72 progressive.
You know most people type and post quickly with just a few seconds to proof read right?

Yeah, id have thought you would be one of them I knew exactly what you meant, i was merely taking the piss 
I know most people find it hard to take a joke on forums too, but thats ok, i dont expect you to be as easy going as i am Dont take it personal, cause its not 
How far from Burlington are you by the way?
