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.
We've independently bought and tested over 60 projectors, and we've published all the 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 methodology is also public on our website, so you can validate the results yourself.
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.
Great 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.
The LG CineBeam Q is not 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.

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 Hisense C2 Ultra is decidedly better than the LG CineBeam Q, but they're in different price and size classes. The Hisense is a far bigger and pricier unit, but it's also significantly better: it's brighter, more accurate out of the box, and even more colorful than the LG. Still, the LG has slightly better contrast, which is impressive for a projector in its class.
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 compensates 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.
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: it has an integrated battery, which slightly gives it a leg up when it comes to portability; with the LG, you'll need to have a power bank with you if you want to use it away from an outlet.

Test Results
The LG CineBeam Q's brightness is sub-par. Still, for a small portable projector, it really isn't that bad. Of course, it works best with the lights off, as it's not bright enough to overcome any lights. On the plus side, brightness uniformity is fantastic, so you get very few dark spots across the screen. If you'd prefer a brighter projector, check out the Epson EpiqVision Mini EF21 instead.
The LG CineBeam Q's contrast is great. It especially excels in darker scenes, but blacks stay deep even in brighter content. Overall, this is a projector that will satisfy almost anyone when the lights are off.
This projector's SDR pre-calibration accuracy is sub-par. Reds are noticeably underrepresented in almost every shade of gray, making the unit's color temperature very cold out of the box. As for color accuracy, it's decent. Still, many colors are slightly off the mark, and there are a fair number of color mapping issues in yellows, whites, and most light colors.
The projector is very easy to calibrate due to its 22-point white balance and full color calibration. Doing so fixes most of the projector's issues, with only a few colors, like greens and especially red, still being a bit off the mark.
The LG CineBeam Q's color gamut is fantastic. It covers the entirety of the Rec. 709 color space. It even covers most of the wider Rec. 2020 space that is sometimes used in HDR content, although here, most colors are slightly off the mark.
This projector uses a 3-channel RGB laser light source rated for 20,000 hours, so there's no traditional lamp to replace. The projector achieves its pseudo-4k image using pixel shifting. That means fine detail is very good on this unit, but it isn't the same as a native 4k image.
The LG CineBeam Q uses a fixed ~1.2:1 throw with autofocus and auto-keystone. There's no optical zoom or lens shift, so plan placement carefully and try to keep the lens centered on the screen. Here are some quick projector-to-screen distances to help with your setup:
- 50" image: ~4.4 ft
- 80" image: ~6.9 ft
- 100" image: ~8.7 ft
- 120" image: ~10.5 ft
The LG CineBeam Q is highly portable. It's compact and light, and the 360° rotating handle makes it easy to carry and quickly tilt the projector for wall or ceiling viewing. Setup is fast thanks to Auto Screen Adjustment and autofocus, so you can place and play the unit without much fuss.
The projector doesn't have a built-in battery, though, so you'll need AC power or an external USB-C power bank; LG specifies 20V/3.25A, around 65W, or higher for operation. Audio is handled by a built-in mono speaker, and there's a full-size HDMI (ARC) plus USB-C for flexible connectivity.
The LG CineBeam Q is a bit louder than a typical living-room LED projector when driven at maximum brightness, so you'll hear a steady whir in quiet scenes.
The LG CineBeam Q has an HDMI 2.1 port with ARC. Its USB-C supports DisplayPort Alt Mode video input and USB Power Delivery. You can power the projector via a USB-C charger or power bank that is 65W (20V/3.25A) or higher, and the port can supply up to 5V/1A to external devices. For wireless, there's Bluetooth and Wi-Fi. The Wi-Fi only supports WPA2.
The projector accepts 4k @ 60Hz and 1080p @ 60Hz (including 4:4:4), but it doesn't support any 120Hz modes. 1440p @ 60Hz is accepted only as a scaled signal.
Input lag is consistently high across the board, even in Game Mode, and is too slow for most gamers, even those playing slower single-player titles.
The projector only offers ARC (no eARC) and provides no user-facing audio passthrough settings. In practice, it can return audio from its built-in apps over ARC, but external HDMI sources don't pass through, and multichannel/lossless formats aren't supported.
