User Manual Cameras Home Cinema 4010 Epson

No, it is not a true 4k. It uses a different process to arrive at a
near true 4k picture quality. True 4k projectors are double this
price range and higher. Unless you are projecting on a very large
screen or sitting close to the screen the difference is negligible
in my opinion. It will use the data from 4k UHD discs so no
worries about compatibility and it will up-convert 1080 Blu-Ray
to near true 4k quality. Unless you are a purist and have the
extra money to spend on a true 4K projector I would advise you
to buy this and save your money for the next generation, 8k,
which is in the works. Spend a little extra on a quality 4k player

The Epson Home Cinema 4010 does not have horizontal keystone
correction. If the projector cannot be centered in front of the
screen, use lens shift to reposition the image instead of using
keystone correction for better image quality.

The size of the image of the Epson Home Cinema 4010
Projector is determined by the distance from the projector’s lens
to the screen. Depending on your display settings, source signal,
and amount of zoom, the actual size may differ. You can
calculate an image size or the projector distance using the
Projector Distance Calculator, which is available from the
Downloads tab for this product.
