“How well does the keystone on this projector work? Does it change the image in any way?”

1-5 of 5 Answers

• Hi KyFan, The keystone feature on the EpiqVision Mini EF11 projector corrects the keystone effect caused by projector placement or wall issues. The keystone effect is a distortion of the image. The EF11 keystone feature corrects that distortion. Regards, Mark - The Epson Team.

• Pretty well. It moves in steps, and the *vertical* keystone is automatically set. You can always adjust the Vertical and Horizontal manually. This will change the image, due to the way the keystone works on this. That means you'll have black "bleed" on the sides if you put too much keystone. The picture will not be cut off in any way, however.

• Yes, it has the keystone function. You can adjust it so the image is square. If you are very picky it is hard to get perfect, but you can get it pretty close.

• I think it works well. I was able to change the angle to the wall and it automatically adjusted every time. I did not try any extreme angles, but it did very well under normal operating conditions.

• I have this projector and the only adjustment is focus. It pretty much has to face the screen or wall straight on.
