Acer K750 – Sound Quality

If you’re in any way serious about using the K750 as a home cinema machine you definitely won’t want to use its built in speakers for your audio. Even by the usually puny standards of integrated projection audio the K750 sounds flimsy. Its maximum volume levels are nowhere near sufficient to deliver a soundstage big enough to partner images as large as those a projector is designed to deliver; there’s practically no bass in the mix at all; trebles sound harsh; and voices sound like people are speaking into a tin can for most of the time.

it doesn’t help, either, that because the K750 has a fairly long-throw lens the sound it produces seems hugely disconnected from the images it’s supposed to be accompanying.

Other Things To Consider

The K750 runs quite noisily if you don’t use its Eco lamp setting, making that setting pretty much essential for movie viewing. But since this setting also reduces brightness quite considerably you really do need to be able to black out your room if you’re thinking of using the K750 as a home cinema machine.

If the K750’s long lamp life sounds like a great match for a heavy-duty gaming addiction, then we’ve got more good news: we measured input lag from the projector at just 33ms, which is small enough not to seriously damage a typical gamer’s performance.

Should I buy an Acer K750?

If you’re a particularly heavy projector user then the K750’s huge lamp life is clearly a draw. Especially as this benefit has been delivered while retaining better picture quality than we’d expected.

Well-calibrated pictures aren’t as bright as those you’d get from a normal LCD or DLP projector, though, and it’s also the case that similar black-level reproduction and slightly better colour response can be produced by standard UHP-lit DLP projectors costing well under £1000. Although those won’t, of course, give you the lamp life benefits and associated potential savings of the K750.

If you’re after a data projector first and foremost, though, the K750’s green bias when running brightly make it a seriously flawed option.

Verdict

The K750’s long lamp life is a boon for heavy users, and it’s a surprisingly solid performer with movies if you’re careful how you set it up. We just hope that, if Acer makes a second-generation hybrid projector, it manages to find a way of controlling its greens better when you want to run it brightly.
