Hello,

I am thinking of buying a CRT projector for home theater. I would really like qxga for pc gameing. The specifications of the electrohome 9000 are max resolution of 2500x2000.

This site http://www.curtpalme.com/CRTPrimer_14.shtm gives me the impresion that i will never be able to get the resolutions i want. I am guessing i don't understand somthing.

Can someone explain? Is high fps, deinterlaced video going to lesson the chances of getting a high resolution?

Thanks!

The 9" machines are mostly capable of resolving 1080p(1920x1080 widescreen) for home theater, when dialed in correctly and in good condition. Qxga will be pushing the limit, depending on what aspect ratio you plan on displaying it at.

Keep in mind that long-time static images(HUD's etc) pose a major risk for burn-in on the tubes. You definitely will need a good 9" machine to do this anyhow, which will cost not too much less than a decent 1080p digital that will be great for gaming. It's all a matter of preference, though, and after you let us know exactly how much gaming/movies you plan on running, and your pickyness for life-like movie presentations, we can advise you more.

25 hours of use a week max, half of that gaming. I don't plan on running the tubes at full brightness so that should help to prevent burning.

I enjoy tweeking and modding so thats another plus for CRT.

What is limiting the projectors resolution exactly? Inductance or speed of transistors? I am thinking the internals could be repaced with newer, lower inductance, higher bandwidth components.

Isn't QXGA = 2048×1536?

Spot size of the electron beam as well as optical focus and convergence. 1920x1080p is pretty much the maximum for CRT resolution unless you want to spend lots of money on upgrades and professional calibration.

Yes, close to 1080 but 3:4.
