The LG ProBeam BU70QGA is a top-tier 4K DLP projector priced at $5,499. It uses a multi-channel laser light source that delivers up to 7,000 ANSI lumens of brightness and a dynamic contrast ratio of 3,000,000:1.
This projector is LG’s first ProBeam model designed for their digital signage line. While it’s great for many business uses like simulators and meeting rooms, it’s mainly aimed at digital signage. Still, it’s powerful enough to work well in home theaters and living rooms for projector fans.
The BU70QGA has a 4K UHD resolution (3840 x 2160), a laser light source lasting up to 20,000 hours, and features auto lens shift, zoom, and focus with a 1.6x optical zoom.
It also offers many connectivity options, including two RJ45 wired network ports—one for HDBaseT and one for LAN—as well as wired and wireless network connections.
This is a high-performance projector with powerful features. Later in the review, I’ll talk about LG’s webOS 6.0 signage platform, which is fully integrated into the BU70QGA. This software helps manage and display digital signage content and is available to many LG partners.
We’ve also reviewed other LG ProBeam models like the BU60PST and BU53PST, and were very impressed with their picture quality and features. You can check those reviews through the links above.

OVERVIEW
LG, known for making flat-panel TVs, understands that many want a bigger, more immersive viewing experience beyond what even the biggest OLED or LCD TVs can offer. The BU70QGA ProBeam projector is made for business and education professionals who need large, clear projections.
This projector uses Texas Instruments’ 0.65-inch DLP chip with XPR technology to deliver sharp 4K UHD (3840 x 2160) images.
It features a laser-phosphor light source rated at 7,000 ANSI lumens, which means it can produce bright, clear images even in rooms with a lot of ambient light. Saying this projector is bright doesn’t do it justice.
The LG laser light engine is sealed to keep dust out, so the image stays clear over time.
With 7,000 lumens of brightness, the BU70QGA works well in big spaces like halls, museums, or other bright places. The laser light can last up to 20,000 hours, meaning you could use it for 8 hours a day for about seven years without needing much maintenance.
Thanks to the laser and 4K DLP tech, this projector is reliable and comes with a three-year or 15,000-hour warranty. Plus, because it doesn’t need lamp replacements, it can be installed in hard-to-reach spots like high ceilings or museum displays without worry.
The BU70QGA has a high-quality lens with both horizontal and vertical lens shift.
It features a 1.6x optical zoom and automatic lens shifting, making it easy to adjust the image without digital tricks. This helps when mounting the projector in tricky spots or on existing mounts.
You can also use the remote control or a PC, phone, or tablet to focus the image automatically.
For special cases, like projecting on uneven surfaces or using multiple projectors to create one big image, the BU70QGA offers 4, 9, 15, and 25-point Warping tools. These help fix image distortion and align the picture perfectly.
The projector supports up to 9 projectors working together, which can be connected easily using the built-in HDMI ports.
The BU70QGA lets you rotate the image without moving the projector. You can show pictures horizontally or vertically with no need to adjust the projector’s position. LG also says there are no limits on how you install it — no matter the angle.
This projector comes with several built-in presets: seven for video and six for audio. These help you get the best picture and sound in different settings.
It has two built-in speakers and supports HDMI Audio Return Channel (ARC), making it easy to connect to soundbars for better sound. For home theaters, the ARC supports Dolby Digital and Dolby Atmos. Plus, it has Bluetooth to connect wirelessly to Bluetooth speakers or sound systems.
LG ProBeam BU70QGA projector supports rotating images without needing to move the projector itself.
While it doesn’t have all the smart features of LG’s CineBeam line, the BU70QGA has strong connectivity and productivity tools. It runs on LG’s webOS 6.0 Signage Platform, designed for business and education. This platform connects to LG ConnectedCare, a cloud-based device management system, and supports over 50 third-party content partners.
webOS 6.0 lets developers create custom apps that run directly on the projector’s built-in chip. This makes it easy for partners to add projection features to their software. The BU70QGA is LG’s first 4K projector with this powerful software platform, offering wide content management and distribution options.
It also supports control through popular third-party systems like Crestron, Control4, Savant, and RS232C. You can wirelessly share screens using LG’s optional QuickShare USB transmitter and software.
With 7,000 ANSI lumens brightness, low maintenance, and the ability to work alone or network up to nine projectors, the BU70QGA is ideal for places like retail stores, museums, and large halls for trade shows or events. It makes streaming and content sharing easy and flexible.

HARDWARE
Compared to other LG ProBeam models, the BU70QGA is a large projector. It measures 22.4 x 14.2 x 6.3 inches (570 x 360 x 160 mm) and weighs 39 lbs (17.7 kg). If you’re not used to handling heavy projectors, it’s a good idea to get help when moving and setting it up.
CHASSIS
When the BU70QGA sits on a table, its lens is right in the middle of the front panel. The front also has a built-in camera to help with quick setup, focus, and zoom adjustments. One of the two infrared receivers is here too. The cooling air intakes are located on the front as well.
All the inputs and connections are on the back of the projector. The cooling exhaust vent and the power button with a joystick control are on the rear panel, along with the control panel for menu navigation.
For great flexibility, the BU70QGA includes several video inputs like HDMI, DisplayPort, and HDBaseT. It even has an HDMI output for connecting multiple projectors in a chain. See the photo below for all the controls and connections.
All inputs and controls on the LG BU70QGA are located on the projector’s rear.
The LG BU70QGA remote control has many useful features but unfortunately doesn’t have a backlight.
It’s a traditional remote with plenty of buttons to control all the projector’s functions. You can easily adjust settings for different types of content and lighting. Switching from a bright presentation to watching TV or sports in the dark is quick and simple with just one button.
You can also control most projector functions using LG’s software like LG Control Manager.
LENS
The ProBeam BU70QGA has a 1.6x zoom, which lets you place it at throw ratios from about 1.53 to 2.45. It also has electronic lens shift for moving the image horizontally and vertically.
You can adjust the lens shift two ways:
Auto Screen Adjustment, which sets zoom, focus, and lens shift automatically using the remote or the control panel.
Manual adjustment for fine-tuning.
Keep in mind, shifting the image one way limits how much you can shift it the other way. The lens shift range is horizontal ±28% and vertical +60%/-33%, with auto options.
To figure out throw distance, use this formula: Throw Distance ÷ Image Width = Throw Ratio. I’ve included a chart above to help with this.
Edge blending is a great feature on high-end projectors like the LG ProBeam BU70QGA. It helps you join images from multiple projectors smoothly by overlapping their edges so there are no visible lines or gaps.
While using the optical Lens Shift gives the best picture quality, the BU70QGA also has an EDGE BLENDING mode with 4, 9, 15, or 25 adjustment points. This lets you fine-tune the alignment and brightness to make the images blend perfectly.
This feature is especially useful for big places like theaters, museums, exhibitions, and corporate events, where you want to create large, impressive displays that grab attention.
MENUS
Like LG’s other digital signage displays, the BU70QGA has a built-in webOS System on Chip (SoC). This lets the projector connect directly to a server and play media without extra devices.
You can also plug in a USB drive and use webOS to browse and play images or videos in common formats. This is great when there’s no network available.
LG webOS is a web-focused platform with strong features for creating rich web apps. Its menus are easy for developers and users, letting you control many projector functions like content playback and adding new services.
The BU70QGA’s menu is very user-friendly, even with all its features. It includes helpful visual guides for making adjustments.
Performance – Color Reproduction
The BU70QGA shows bright, vibrant colors. Its color profile is like other LG ProBeam 4K laser projectors I’ve tested. Since it’s a DLP projector, colors can be a bit oversaturated out of the box, with cooler tones leaning toward greens and blues. This color setup works well in bright places like retail stores, tradeshows, and pop-ups.
In the first three pictures above, you can see how the projector’s colors look right out of the box when watching movies. Notice the green shades in the Spider-Man scenes, especially in the grass and the white bricks of the Washington Monument. Skin tones look pretty good overall, but like many DLP projectors, reds in skin are a bit stronger.
LG offers many picture settings like White Balance, Gamma, and Color Management System (CMS) so you can adjust the picture to suit your room.
Here are my thoughts on the preset picture modes:
MALL/QSR: The brightest but least color-accurate. Best for presentations where being seen clearly is more important than perfect color.
GENERAL: A good balance of brightness and color accuracy. Makes light and dark areas clear and dynamic.
TRANSPORTATION: Best for places with lots of uncontrolled light. Strong colors help the image stay clear even at high brightness.
GOV/CORP: Realistic colors and smooth gradation. Good for videos in rooms with some ambient light.
EDUCATION: Great for dark rooms, with good contrast and color. Ideal for presentations and classrooms where lighting is controlled.
EXPERT: Similar to cinema modes on home projectors, balancing detail and color for a natural look.
CALIBRATION: For experts or anyone wanting to fine-tune the picture for the best quality.
HOSPITAL: Like DICOM-SIM mode, made for medical images like X-rays and MRIs.
BRIGHTNESS
BLACK LEVEL AND SHADOW DETAIL
The BU70QGA’s biggest strength is also why its blacks are only average. Most 7,000-lumen DLP projectors can’t produce deep blacks, but that’s fine for digital signage where bright, vivid colors are more important.
The blacks on the BU70QGA look more like dark gray. Still, details in both dark and bright areas are clear, even with the room lights on. This makes the ProBeam BU70QGA a great choice for places with lots of ambient light.
VIDEO IMAGE QUALITY
The LG BU70QGA delivers great video quality right from the start. The colors are bright and natural, and the blacks are pretty good too. I didn’t need to tweak the colors to get the images you see. Most screenshots were taken in the GENERAL and EXPERT modes.
Built for business and education, the BU70QGA uses video processors similar to LG’s 4K HDR TVs. It supports HDR10 and is one of the few business projectors with Dynamic HDR Tone Mapping. This feature, borrowed from LG’s CineBeam projectors, adjusts the picture automatically to make HDR look its best.
TEXT AND PRESENTATION QUALITY
The LG BU70QGA ProBeam projector displays sharp 4K UHD (3840 x 2160) resolution, making text clear and detailed. Thanks to this high resolution, you can sit close to a large screen and still see a crisp image—better than the common WUXGA (1920 x 1200) resolution in many business projectors. This makes it easy to show multiple documents or web pages on a big screen, which is great for work.
AUDIO QUALITY
The LG BU70QGA has two 5-watt speakers loud enough to fill medium to large rooms. The sound works well for classrooms, meeting rooms, and many other professional settings.
The ProBeam BU70QGA’s fan noise is between 31 and 35 dB, which is quieter than most other 7,000-lumen projectors. It’s a little louder than some large home theater projectors, but in places like retail stores or digital signage, the fan noise won’t be noticeable.
SUMMARY
The LG ProBeam BU70QGA is LG’s first professional projector designed just for digital signage. Until now, LG’s digital signage products were only flat-panel displays. This projector gives businesses new options to display content that flat panels can’t.
For this article, I spoke with Susie Opare-Abetia, founder and CEO of Woven Media, one of LG’s growing partners in digital signage. We talked about what excites her about LG’s first digital signage projector and working with LG.
Projection helps companies like Woven Media connect their retail clients with customers in stores or on-site. Projectors like the BU70QGA can use floors, walls, and other surfaces to show high-res, scheduled, and flexible content in ways flat panels can’t.
Woven Media trusts LG because of its long history, quality, and innovation in display technology. They also value LG’s webOS 6.0 for Signage platform. With webOS, LG removes the need for extra devices like laptops or media players to run content. This cuts costs and reduces potential issues by simplifying the system. Tools made by Woven Media can run directly on LG’s webOS displays.
webOS improves communication and control between LG displays and content management systems like Woven Media’s. It also gives partners more customization, control, and interaction than traditional third-party solutions. Overall, LG offers a stronger, easier, and more flexible solution for partners and their clients.
The BU70QGA is part of a group of display products that used to be only flat-panel TVs. It’s LG’s brightest professional projector, with 7,000 ANSI lumens.
With its 4K UHD (3840 x 2160) resolution, the BU70QGA shows images almost four times sharper than typical WUXGA (1920 x 1200) projectors. It can display detailed content on screens up to 300 inches. It also supports edge blending with up to nine projectors for bigger, custom-shaped images.
This high-quality DLP projector uses a laser phosphor light engine that can run 24/7 for 20,000 hours without changing lamps. It’s the brightest business projector LG has made.
Users get the same great quality and care found in LG’s consumer products, plus the reliability, warranty, and support needed for business use.
The ProBeam BU70QGA can’t match the deep blacks or native contrast of home theater projectors, but it works great in rooms with ambient light. Blacks look more like dark gray, yet the projector still shows clear details in both dark and bright areas.
It has a 1.6x optical zoom lens, with automatic and manual zoom, focus, and lens shift (horizontal and vertical). This makes installation very flexible.
The BU70QGA supports both wired and wireless networking—a feature many professional projectors don’t have. You can connect it directly to a network to access photos, videos, and other files.
Since it’s designed mainly for digital signage, movie colors like in Top Gun: Maverick might look a bit off in most preset modes. But it offers professional calibration tools to adjust colors for a more neutral, movie-friendly look.
This projector is ideal for large rooms with lots of light—like meeting rooms, halls, or lobby displays. It delivers sharp 4K images with 7,000 ANSI lumens brightness from its laser light source. The lens can shift and zoom 1.6x to fit your space perfectly. It also has a built-in camera to auto-adjust picture size, position, and focus with just one button.
The BU70QGA is a great value for digital signage, education, and business use. If you want a super-bright projector for classrooms, boardrooms, or places of worship, this LG ProBeam is hard to beat. Priced at $5,499 MSRP, it’s a top pick for digital signage.
