Hi all.
I have recently had a warranty replacement Optoma UHD42 and I believe (hope) it "is" new and not a refurb.
Since setting it up in the original position of previous PJ there is a very obvious issue with the focus. If i focus the top, the bottom
focus is out and if i focus the bottom, the top is out?
With an accurate horizontal and vertical level, the focus is good about half way up to top of picture but loses focus
from half way to the bottom of the picture. I've posted a pic to explain better. The keystone is zero and the vertical shift is almost
at max but even moving the pj up or down from vertical centre doesn't change the problem...Any ideas?
Many thanks in advance
Kind regards
