Hey ladies,
and sorry for posting in engish. I found some time to shoot some resolutions (up to 4k) into my Ultra. It´s consumer 4k at 3840x2160 run in an 2,4:1 (22:9) aspect ratio resulting in an 3840 * 1600 resolution. I use a Marquee 9500 Ultra with high resolution tubes (PT22) and HD10R5M curve screen lenses. The lenses are made for curve screens and based on the plain HD10 lenses. More tests need to be done with HFQs, HD10GT17´s an HD10f´s. The test pattern shows one pixel as one line, so the better you see each single line the better the resolution is resolved. As 4k with one single projector was... well look for youself in the video, I also added blend resolutions. They got mastered by the Ultra!
Have fun:

Ps.: In fact even the desktop looked ok/good in 4k! Youtube degrades the video to much with compression, so you can add mentally lot of sharpness.
I will continue my tests with premium 4k content. I will also try do interlace 4k. So far I am maxed out in interlaced at 2560x1080i Vista/Win7/Win8.
And I think with so some digital sharpening in the post processing (based on the 4k pixel count!) in our home cinemas, we can get a good looking 4k out of some tubes! Stay tuned for the next video.
