Owners describe the headline as almost implausible: 4,000 standardized lumens from a 30,000-hour laser at under $1,900. Owners of the model it replaces, who were already happy with it, describe the brightness increase as the reason to upgrade, and the 1.6x zoom makes it far more flexible to place than Optoma's cheaper lamp projectors.
The complaints are specific rather than sweeping. Owners report hotspotting at shorter throw distances — the same owner sees it at 2.8 metres and not at 3.5 on the same screen — which is a warning to model the geometry rather than assume it will work anywhere in the zoom range. And the volume control is coarse enough that owners raise it as a real pet peeve: around ten steps across 30 W of output with a minimum near 3 W leaves no fine adjustment at low levels.
The practical constraint is the throw ratio. At 1.40 minimum, owners calculate roughly 129 inches from 4 metres, which is well short of what someone planning a 150-inch screen in a normal room will get. Owners are blunt that this is the calculation to do before buying any projector, and that it catches people out constantly.
