Hello everyone. Have been gone for quite awhile and really missed reading posts around here. Do need some help as to what the optimal picture size would be for a Marquee 8500 with really good tubes and color filtered lens. In other words, how wide can I go (maximum) before the corners become problematic and the picture is washed out. Thanx in advance for any and all insights. I'm asking specifically because, unless I've msiunderstood (which is entirely possible - Curt can attest to my very limited knowledge in these matters Smile

the HD145 lens already decrease light input due to their color filtering and since they are also 1:1, after a certain distance from the screen the picture becomes compromised; The aperture appears to be much smaller than that of the standard HD8 lens. Regards.

Sorry I missed your calls. There's no real answer for this question. Most people set up a 52 X 92" screen for HD use, but I've seen the sets pushed to 120" wide in a perfectly dark room. THe die hards say that you should not go over 72" wide on occasion, but to me that's tiny.. Smile

Why not set it up on the floor first, and do very rough setups on a white wall to see what you like? Wasn't that care home using an ECP 4500 at 750 lumens on a 9' wide screen? If that was bright enough, then the Marquee will be slightly brighter.

Greetings Kind Sir Smile

You have shown me a sign of life. Well, first and foremost, it's really nice to hear back from you! I genuinely mean that because I truly missed this whole CRT thing in a profound kind of way despite the lack of my technical competence. However, Thanx to all fo your very kind collaboration over the years, I managed to learn a few things over the course of our numerous exchanges; For this knowledge - I salute you. Yes, the retirement establishment had an ECP4500 projecting an almost 10 foot wide screen which was most palpable. I concurred with you at the time that the nice quality of picture generated was primarily due to the fact that the tubes were virtually new thereby not causing any problematic effects. I want to get the maximum size piucture while successfully maintaining a very high quality level. I remeber reading somewhere that you typically should not exceed 100 inches. My intention is to hook up the Marquee 8500 to a Playstation 3 for Bluray viewing. Best Regards to all. (I will try to call you again Curt). Have a great labour day weekend.

for a flat screen 52 x 92 with 1.3 gain is really MAX IMO. any bigger than that and you'de better be either using a torus or more than 1 CRT projector. I like a picture that really pops off the screen and when you get too big the image will still look good but you lose all the WOW factor of a big, powerful image.

Picture size typically refers to the size of the image on the tube face.

Screen size usually refers to how big you want the picture on your wall to be.

Stick with about 96" wide for optimum screen size at a maximum size. 80's would be best of course, but I think 96" is where you really start to lose some brightness/pop/depth. It still looks great at larger sizes of course.
