The HD31UST also comes packing 4-corner correction and I think this is a great step in the right direction. It makes uneven walls or awkward placements and setting up a projector in general a complete breeze when you have 4-corner correction built in.
While it may not be totally inconspicuous in the environment , it still manages to fit well into the living room thanks mainly to the sleek modern lines and matt white finish.
In terms of fan noise it definitely is one of the more silent options currently out there on the market coming in at 25dB.
Black levels were decent.
The overall picture quality for an ultra short throw 1080p – it’s rather good.
