This projector exists in owner discussion as the answer to one question: what is the cheapest way to get a native 4K imaging device with a laser light source. Owners who have chased that requirement describe finding one at or below half of list price as the moment the purchase made sense, and they are clear that at full list the calculation is harder.
What owners praise is the processing and the quiet. Sony's picture engine gets consistent credit as a step above the single-chip DLP competition, and owners coming from pixel-shifting projectors mention escaping both the visible pixel-shift compromise and the mechanical noise the shifting actuator makes.
The criticisms are specific rather than general. Owners report the lens is not as sharp as the one in Sony's earlier lamp projectors, gamma behaviour draws repeated complaints, and the recommendation owners give is to take the 3LCD rival instead if motion handling and gaming matter more than native resolution.
