Guys


The pics say it all. Sixteen good years. Contrast 50, Bright 45. G2s are maxed out on the left. Marquee 9500LCs with HD10L lenses.







I'll be working on the left side 9500 the next few days and then a few hours dialing them in. Convergence is very stable.

More pics coming, using my new Sony HX400V camera 20mpxl set to 5mpxl.

Nice !!

For those you used to say blending is a thing of the past
After seeing locally and helping get even better results
I’ve seen Barco 909 x2 over approx 6 meters and well

Tim I’m jellous I only have 1 Barco 909 up

Where you get your new tubes from ?

Nice !

Might as well use up those tubes while you have them! How many hours did the worn tubes you ran for 16 years have?

8000 hours with two blended projectors running filling a 107" wide screen? I would have thought with each projector not having to paint the whole 107" width that you'd be able to get more hours out of that, but maybe not.

How many foot lamberts (or nits) do you measure/target? You must be much higher than the 14-16 ftL recommended by SMPTE for non-HDR content I'd imagine given that the screen isn't overly huge? Hell, I was doing 14 ftL on my 96" screen with a single 8" CRT projector that I obtained new and put almost 8500 hours on it and it was still showing 14 ftL with the original tubes when I sold it ( https://www.curtpalme.com/forum_archived/viewtopic.php@t=32972.html ) so you must be pushing those 9" tubes hard for more light. Nothing wrong with that - I say use up whatcha got!

I don't have the test gear, I'm not ISF but 260 lumens published spec x 2 on a 1.0 gain fabric has wide viewing angle and is more than I need at contrast 50.

All the new tubes are in and I'll be aligning the next day or two. Monday Night Football here on ABC!!!!!!!!!

No need for ISF or anything fancy if you want to know. You can use a free app on your smartphone and it's probably reasonably good enough. Handheld ones are dirt cheap too, like $20-30. I use this one: https://amzn.to/3Zjc04R
