A laser that states 5 500 ANSI lumens against a laser that runs on a battery

ViewSonic LS740HD laser projector, 5 500 ANSI lumens vs XGIMI MoGo 4 Laser portable projector with battery

Which laser projector suits my room?

By

A laser light source is the only thing these two share. The ViewSonic is an installation machine: 5 500 ANSI lumens, a stated 30 000-hour life, two HDMI 2.0 inputs and a 15 W speaker, at Full HD native resolution. The XGIMI is a battery-powered portable, and its listing states no brightness figure in a measured unit at all. Which is right depends entirely on whether the projector stays in one room.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.

Which one, for whom

Buy the ViewSonic LS740HD laser projector, 5 500 ANSI lumens

Buy the ViewSonic for a room with a screen in it. It is the only projector in this catalogue that states both a high ANSI figure and a lamp life in hours.

Buy the XGIMI MoGo 4 Laser portable projector with battery

Buy the XGIMI if the projector has to leave the room. A battery and portability are things no installation projector offers, and no ANSI figure replaces them.

Questions people actually ask

Is 3 000 000:1 a real contrast figure?

It is a dynamic contrast figure, which measures the brightest frame against the darkest across different scenes rather than within one image. Native contrast — what a single frame actually shows — is a much smaller number and it is the one that decides how a dark scene looks. This site reports the figure as published and names what kind it is.

Why does a portable projector not state ANSI lumens?

Because ANSI is a demanding measurement and portable projectors rarely come out of it well. A listing that states brightness in an unqualified unit, or not at all, is telling you something by omission. It does not make the projector bad; it makes the number unavailable.

    Best for: A room with ambient light where a lamp replacement every few thousand hours would be a nuisance — a classroom, a lounge, a bright living room.
