A 1080p LED projector built around color accuracy rather than pixel count: 98% Rec.709 out of the box, a 20,000-hour LED that never needs a lamp, and just enough vertical lens shift to clear a coffee table. It is the cheapest way into a projector that will still look right in ten years.

The two lists above are read off manufacturer specifications and published measurements, not from owner reports. Where owner discussion has been collected it appears separately below, so the two are never mistaken for each other.
Owner discussion places this squarely as the replacement for BenQ's long-running budget 1080p projector, and the comparison with that older model is the whole conversation. The LED light source is the reason to move: no lamp, no brightness decay, no consumable. The price increase is the reason to hesitate, and owners are open about that being a real trade rather than a free upgrade.
The technical point owners make most often is about resolution. This is a 1080p device that accepts a 4K signal, and experienced owners are clear that this is not marketing: the wider colour space and HDR metadata carried by a 4K source genuinely improve what a good 1080p projector puts on screen, and the resolution difference at normal seating distances on a normal screen is small.
The consistent caution is brightness. Owners describe BenQ's LED models as not especially bright, and pair that with advice about screen size: this is a projector for a screen around 100 to 120 inches in a room with some light control, not a 150-inch installation.
Owners split on this. The case for is that a 20,000-hour LED source removes lamp replacement from the ownership cost entirely and the colour does not shift over time. The case against is that the older lamp model was already excellent and cheaper. Owners who keep projectors a long time favour the LED.
Owners argue yes at this price, on two grounds: a good 1080p projector beats a bad 4K one, and the resolution difference is small at normal seating distances — roughly ten inches of screen diagonal per foot of viewing distance is the rule of thumb they use. It also accepts 4K sources and uses their colour and HDR information.
2,300 ANSI lumens, and owners describe it as adequate rather than abundant. Several note that BenQ's LED projectors generally are not brightness leaders. It works well on a 100 to 120-inch screen with some light control; it is not a bright-room projector.
No. Owners plug in a streaming stick, and several add that the built-in speakers on projectors in this class are generally poor, so an external speaker or receiver should be part of the budget.
Owners are consistent that under about $1,000 there is no good 4K option, and that a well-built 1080p projector with real contrast and a decent lens gives a better picture than a budget 4K unit. The sub-$300 units in particular come in for repeated warnings.
