LG recently launched one of the more affordable options in the form of the new LG HU70LA (HU70LS in the UK) CineBeam 4K projector, available for $1,799 (£1,650, around AU$2,900). That’s not exactly cheap, but compared to other native 4K projectors that cost three to five times as much, it’s a downright bargain.

Its minimalistic design is reflected even in the buttons on the projector itself. The HU70LA’s unusually small size and weight for a 4K projector—3.7 x 8.3 x 12.4 inches (HWD) and just 7.1 pounds—helps make it easy to set up. It’s also easy to carry to the backyard for a movie night.

The included remote does most of the heavy lifting (including focusing!) so you won’t have to worry after you’ve mounted it to your ceiling. It uses 4 Channel LED with Wheel-less technology. The HU70LAB uses RGB separate primate colors, giving it a bright, vivid picture with no color loss


  • Audio Out: Mini Jack
  • HDMI (DHCP 2.2)
  • HDMI 2.0
  • Network: RJ-45 (ethernet)
  • USB x 2
  • Wireless Networking

Connections are expectedly on the back and consist of two HDMI 2.0 ports with HDCP 2.2 (one with ARC), two USB 2.0, one USB-C, optical out, 3.5mm audio out, Ethernet, and a standard SMA coaxial socket for the built-in digital tuner. In addition to the wired connections, the HU70LA also supports Bluetooth connectivity, wireless sharing with iOS and Android devices that have the LG TV Plus app installed, and screen sharing with Miracast.


For a 100-inch image, the throw distance ranges from roughly 8.75 to 11.0 feet. the HU70LA combine all the smart capabilities of flat panel TVs with the long life of a LED light engine and 4K resolution to create a true flat panel TV replacement.


 I measured it at 821 ANSI Lumens, which is bright enough to fill a 16:9, 130-inch diagonal, 1.0 gain screen in a dark room, or a 90-inch, 1.3 gain screen in moderate ambient light—even without taking the promised higher perceived brightness for LED projectors.


The HU70LA offers eight preset color modes for SDR. Switching back and forth between them made it obvious that Standard, Sports, HDR Effect, and Game modes were blue shifted relative to Cinema and both the Expert (Bright Room) and Expert (Dark Room) modes. Except for the Vivid and Sports modes, however, which occasionally delivered oversaturated color in some scenes, none of the modes were far enough from accurate to move memory colors—like skin tones, blue skies, or green grass and leaves—out of a realistic-looking range. 


The HU70LA has a 0.47-inch 4K DLP chip with XPR (Expanded Pixel Resolution) pixel-shifting technology. The chip, which has a native resolution of 1080p, is shifted four ways to quadruple the pixel count up to 2160p. The result is remarkably close to a true UHD image and at a normal viewing distance there’s little, if any, visible difference on real-world material. The projector accepts HDR10, but unfortunately is not compatible with Dolby Vision or HLG.


To be completely honest, the 3.0-watt speakers are lackluster at best. For the price point of this projector, you would expect sound comparable to television. That’s just not the case. They lack bass or reverb, making the sound quality flat from the get-go. You’ll want to invest in a soundbar at the very least to make up for it.


The projector comes with LG’s Magic Remote, and it’s generally pretty easy to use. You can use the remote to point at menu items if you want, or simply use the direction controls to make selections. The remote is around six inches long, and has controls for channel, volume, settings, and more. There’s also a microphone button for voice controls, and quick access buttons for Netflix and Amazon Prime Video. The remote isn’t as simple as a Roku or Apple TV remote, but you’ll get used to it.

Streaming apps

You can directly download LG webOS 4.5 Smart TV Platform for streaming apps to the projector, eliminating the need to purchase any other streaming devices like a Roku or Amazon Fire Stick. You can stream 4k movies over Wi-Fi. Additionally, you can also use wi-fi to mirror a device screen or play videos directly from your phone, tablet, or another device.

Setup is straightforward. The lens offset is most appropriate for putting the projector on a table, where the bottom of the image will be roughly at the center of the lens. It’s also suitable for inverting in a ceiling mount, though you may need a mount extension. The 1.25x manual zoom offers flexibility for positioning, while the powered focus adds the convenience of using the remote to get sharp focus easily while standing at the screen.

The projector has eight picture modes for SDR: Vivid, Standard, Cinema, Sports, Game, HDR Effect, Expert (Bright Room), and Expert (Dark Room). Of those eight, four of them — Cinema, Game, Expert (Bright Room), and Expert (Dark Room) — have the ability to adjust white balance (2, 10, or 22 points), and the CMS (saturation, tint, and luminance for RGBCMY). When the projector senses an HDR signal, five HDR picture modes become available. Like the SDR options, not all of the HDR modes are able to have white balance and CMS adjusted. That honor lies with Cinema and Game (User).

With the power mode set to Minimum energy saving (aka, full power), I measured the brightness on my 90-inch diagonal, 1.0-gain white screen at 24.1 ft-L (579 lumens), a bit higher than the 22 ft-L maximum that the Society of Motion Picture and Television Engineers (SMPTE) recommends for a dark room, but not as high as some people prefer. Switching to Medium power mode dropped the brightness to 17.8 ft-L (426 lumens).

Amazing for my first projector

So I have had this projector for almost a year I occasionally used it untill I move to a new house on April and started to use it almost every Day. I love the quality and picture of the projector it really over exceeded my expectations now obviously for best quality it has to be dark I mean have you ever seen a movie at the movies with the light on? Anyways I decided to give it a try on my PS4 on looked great but here come the down side when I started to use the HDR/4k part of the projector after 10 minutes of gaming it started overheating like literally will give you a message that will shut down the projector after a good minute. It’s been about 11 days since I sended my projector for service given that its still under warranty and haven’t heard a thing about it. I just wanted to add that I was told by the LG representative and technician that the problem my projector have has never been reported before so take it with a grain of salt, it’s a great projector totally love it and perhaps I got unlucky and mine was defective. I just hope I can get it back soon.

-No 4K motion processing

It’s a shade pricey for an entry-level device but, make no mistake, this is the king of affordable 4K projectors. It’s easy to set up and install, and produces a picture that’s reminiscent of what you’ll get at the cinema.

That said, it’s as much the convenience of this machine that makes it so good. Bluetooth allows for direct connection with a wireless speaker or soundbar, and the high luminance means that it’s usable in moderately lit rooms. In other words, an AVR, speaker package and home cinema room are not entirely necessary. How’s that for a superb family projector?

You’ll get a great image right out of the box without needing to be any kind of expert at tinkering with the settings. All the preset modes are very well judged and it gives an excellent level of black depth and dark detail for a projector at this price. Colours are balanced and motion is naturally smooth.
