Projectors have countless advantages over TVs. For setting up a home theater, a projector allows your screen to be essentially as large as your wall. The resulting picture puts even giant TVs to shame. And size helps you see more detail.
I have had the projector for less than a month≥. although the picture is great there are some issues.... the fan is rather noisy... the projector bleeds outside the screen... and with no keystone correction you need to lower the projector completely to get a proper picture at seated eye level...
Purchased the UHD51 about a week ago and glad I did so easy to set up and great picture quality a good looking and well made bit of kit.
Upgraded to this projector 2 weeks ago, previously owned a Optoma 1080p projector and the picture upgrade and quality is fantastic.
This projector is astonishing. An upgrade to a budget projector I am totally blown away with the sharp crystal clear quality picture.The projector is very light and still quite compact to its siblings in the range.When running, the fan is very quiet but does pump out some heat.
