Quit splitting hairs and connect the dots. Dig into this: You have the ability to hook up a PC running test patterns to your projector. With this ability, you can explore what I'm saying for yourself.

Nah, I really dont care. I just wanted to have a picture posted to see if I could see the lines. I did the math on your .0022 wire and the gap would be .001 and that gap on a tube face...... I just dont know about naked eye. Now throwing that up on a screen maybe but then its magnified and no longer 300 lines per inch. Well like I said, I really dont care. Keep experimenting though. Thats the fun part.

If you took a natural red pubie and dyed it blue, would the "apparent" resolution change?

CJ,
The light source is a lamp in all light valve projectors. Why do you insist upon pressing and defending this? It is more similar to a LCOS panel than a traditional FP CRT so you can not compare between the two.
BTW, once I got 1080p on a bd500 with 07ms ES tubes by over focusing. However these were new tubes and it would only show at 5-10% drive which made it useless and only if looking into the lenses directly. To get this tread back on track I think most would agree that under ideal conditions a 8" EM CRT can barely do 1080p and a 9' is a little more usable at 1080p. 1080p is nearly the limit of the FP crt platform for 16x9 anyway, any higher and you begin to degrade the image with bandwidth or softening limitations.

Of course the light source is the lamp in a light valve projector. It's not like I haven't spent many hours troubleshooting, repairing, aligning, and testing the four working AmPro LV machines I used to own. The CRT drives one side of the LV and the lamp shines on
the other side of it, with the reflection bearing the transferred image.
However, the performance of the CRT on its side of the LV is typical of any high resolution CRT in every respect except that of course it operates in the near-infrared spectrum instead of fully in the visible light spectrum. The system is adjusted so that the CRT must achieve "peak white" (phosphor saturation" in order for the projection system to achieve peak white. The CRT has to be driven hard enough to
get to peak white on demand, which means that its's going to be subject to the same pattern wear and phosphor degradation issues that
apply to all projection CRTs. Those degradation issues will show up on the screen even though the light valve itself is undamaged.

Frankly I was expecting that post from him...... Anytime hairs or balls are mentioned he's ready to react....

No i dont think you should worry, as long as there is enough distance between you when he brings it up
