Keystone

[Jsgregg]

So, I want to run something by all of you and get some input. I would like to know how many of you are using the keystone feature on your projectors in your simulator setup. This is what I would like to know:

1) What projector are you using?
2) What resolution are you running?
3) Are you using the keystone adjustment?

I'll go first. I am using an Optoma GT760 which I am running at 1280x800 (16:10). The projector has enough vertical offset that I do not have to currently use the keystone feature. I bought a PJ that had vertical offset so that I would not have to use the keystone feature. I do not know that this was at all necessary. I had read that using keystone causes a loss of some resolution, but I have not personal experience with this and do not know whether I would even notice it or not.

Please chime in and share your experience.

Keystone not needed. Projector is horizontal and vertical shift not needed.

1. Epson PowerLite Home Cinema 6100
2. 1920 x 1080
3. No keystone feature, large lens shift allowance.

I have realized a decrease in the picture quality due to digital keystoning on the projectors I use for presentations at work. I believe the technical resolution does not change but your eye will tell you otherwise.

I think the ideal situation is to own a projector with a decent lens shift. Epson's website has an Image Size Calculator where you can enable the "lens shift" feature on the selected projector to get accurate measurements for your potential setup.
