Picture Quality

It’s not always easy to control the lighting when you’re putting on a presentation at work or school. With this LG projector, it’s not a problem. Images will still be bright and clear, even if you can’t completely darken the room.

Along with 4k UDH resolution for stunningly vivid images with plenty of detail, the projector is also HDR 10 compatible. Whether your showing graphs, charts, diagrams, or images, your audience will be able to clearly see everything.

XPR fast-shift pixel shifting ensures faster image display so there aren’t any embarrassing pauses during the presentation. It also helps to produce clearer and sharper images. Add to this the 3,000,000:1 contrast ratio and you will have the audiences’ attention.

What makes this projector ideal to use in ambient lighting is the 5,000 lumens. Most home projectors top out at 3,000 lumens so you will notice the difference.

Installation and Ease of Use

If you’re using a projector at work or school, it needs to be easy to set up and move as needed. LG thought of this when they were designing the BU50NST. The projector weighs around 22 lbs. and only measures 12.8 x 14.6 x 6.1 inches. Its compacts size makes it easy to set up on almost any surface.

The only issue you might notice is the projector’s weight. At 22 lbs., it can be tiring moving it from the class or boardroom.

It comes with horizontal (+/- 20%) and vertical (+/-50%) lens shift so you can easily center images. The only downside is that the projector doesn’t allow for 360-degree image orientation. If it’s your first time setting the LG BU50NST up in a room it might take a while to adjust the images.

You can display images on the wall, screen, or on any other flat, white surface. This does make set-up a breeze, especially considering the projector’s small size.


LG ProBeam BU50NST connectionsWith the LG BU50NST laser projector, you won’t have a problem connecting your external devices. Along with an integrated media player in the USB inputs, there are also two HDMI ports, along with a mini audio output jack.

It does come with built-in 5-watt speakers that are adequate,  but you can also connect external ones if you need enhanced audio. Bluetooth audio is also supported, along with Mirroring and webOS.

Consumer Impressions

Overall, customers are impressed with the LG BU50NST. It does display vivid, detailed images in ambient lighting. It’s also easy to set up in tight spaces. Since it can connect to most mobile devices, you can use your smartphone or tablet to control your presentation.

The primary complaint is when the projector is used at home. You will need to dim the lighting to see image details. You might also have to turn off some menu options when you’re in gaming mode to improve input lag.
