The LG CineBeam Q is a compact 4k pixel-shifting DLP projector that uses a 3-channel RGB laser light source rated for 20,000 hours. Setup is quick thanks to auto screen adjustment features and autofocus. It projects 50- to 120-inch images with a fixed 1.2:1 throw ratio, which works out to about ~4.4 ft for 50″ and ~10.5 ft for 120″. It runs webOS with built-in apps like Netflix, Disney+, Prime Video, YouTube, and Apple TV, and supports casting via Apple AirPlay 2 and Miracast Screen Share. Wireless audio and smart control are covered by Bluetooth, and the unit has a built-in 3W speaker. For I/O, there's HDMI (ARC) and USB-C that supports DisplayPort Alt Mode video and USB-PD power; LG includes a 65W adapter in the box, and the unit can be powered via USB-C PD 65W power bank or higher.
Our Verdict
The LG CineBeam Q is a solid portable option. It has a fully rotating stand and a full suite of image correction features, making it truly easy to carry around with you, even though it lacks an integrated battery. While its brightness is rather sub-par, it's relatively bright for a small ultra-portable model. Its biggest strength, however, is its great contrast; this projector really has deep blacks when the lights are off. It also has a very wide color gamut, although it's not quite bright enough to really make colors pop. It's not very accurate out of the box, but it's quite easy to calibrate. Overall, this is a solid pick if you're looking for a portable unit.
Very portable, with a ton of smart features.
Excellent contrast for deep blacks in dark rooms.
Very easy to calibrate.
Wide color gamut.
Bright for a small portable unit, but still sub-par overall.
Not very accurate in SDR out of the box.
Menus feel a bit sluggish due to high input lag.
Contrast isn't quite as good in darker scenes.
The LG CineBeam Q isn't ideal for gaming. The projector tops out at 60Hz and can't do 120Hz at any resolution, so high-frame-rate modes on consoles and PCs aren't supported. Input lag is also high in Game Mode, and it feels sluggish. It does accept a 4k60 signal and 1080p60 with full 4:4:4 chroma, but 1440p is downscaled, and overall responsiveness holds it back. While it offers decent image quality for a portable projector, it's ultimately not a good fit for gamers.

Limited to 60Hz.
High input lag at any resolution, making it a poor fit for gaming.

The LG CineBeam Q is a dim projector. It's bright enough to provide a good viewing experience when all the lights are off, but it looks washed out when any lights are on. It does have fantastic brightness uniformity, so you don't notice any obvious vignetting.
Bright for a small portable unit, but still sub-par overall.
The LG CineBeam Q's contrast is excellent. It performs especially well in brighter and mixed scenes, where it keeps good separation between elements. It does falter a little in dark content, and its near-blacks don't look very deep, but it's still acceptable.
Excellent contrast for deep blacks in dark rooms.
Contrast isn't quite as good in darker scenes.

Differences Between Sizes And Variants
LG sells the CineBeam Q as a single hardware model (the HU710PB). It has different regional suffixes (e.g., HU710PB-GL, HU710PB.AUS, and HU710PB.ACC), but the core specs remain the same, and we expect all of them to perform similarly, if not identically.
Our unit was manufactured in February 2025.
Popular Projector Comparisons
The LG CineBeam Q is decent overall, but it's truly excellent for a small portable projector. When compared to other similar units, it's leagues ahead in terms of contrast and colors. It's also quite bright for a portable unit, only being bested by something like the XGIMI Halo+. Still, it's not perfect, as it's not very accurate out of the box, and it doesn't have an integrated battery like the Halo+ or the XGIMI MoGo 4. It also has very high input lag at any resolution, making it a poor choice for gaming. Still, overall, the LG is better than both for watching movies, although the Halo+ is more responsive in games.

The LG CineBeam Q is significantly better than the Samsung The Freestyle 2nd Gen. The LG is brighter, has way deeper contrast, and has a wider color gamut. The Samsung is, however, more accurate right out of the box, but that's pretty much all it has going for it compared to the LG.
The LG CineBeam Q and the LG CineBeam S perform very similarly. The main difference between the two is that the CineBeam Q is a short-throw projector with ARC support, while the CineBeam S is an ultra-short-throw projector that supports eARC. Otherwise, both projectors have impressive contrast, wide color gamuts, and are very accurate after calibration. On the other hand, both have disappointing brightness and high input lag for gamers.
The LG CineBeam Q is significantly better than the XGIMI MoGo 4. The LG does everything better: it's brighter, has deeper contrast, is more accurate out of the box, and is more colorful. The XGIMI does have one advantage: an integrated battery, which gives it a slight leg up in portability; with the LG, you'll need a power bank if you want to use it away from an outlet.
The LG CineBeam Q is better than the Epson EpiqVision Mini EF21. The LG is even more portable due to its smaller size and integrated handle. While it's a bit dimmer than the Epson, it makes up for it with far superior contrast, making it look much better in dark rooms. Neither projector is a good option for gaming, but if forced against a wall, the LG has slightly faster input lag due to the inclusion of a Game Mode.
We've independently bought and tested over 75 projectors and published detailed results for each, so you can decide which one to buy. These have all been tested under the same standardized methodology, allowing you to compare them side by side. We still have all these projects in our lab, so we can continually go back and compare them to ensure our reviews are still accurate. All our test methodologies are also public on our website, so you can validate the results yourself.
