I have used over a dozen conventional projectors for work and for personal use and know what to expect when lugging around projectors and having to make wired connections and having to move cords out of the way so people don't trip over them. I have never used a pico projector before, so naturally I was eager to try out the LG Mini Beam.
The first thing I noticed even before I opened the box for the LG Mini Beam projector was how small the packaging is compared to the box for the regular projector. Upon opening the box and taking out the projector, I was truly stunned at how small the projector really is. It is smaller than my hand, and my hand is not even that large. Furthermore, this thing is light, weighing in at a tad over one pound. With such a diminutive size and weight, the projector definitely checks the boxes for compactness and portability. The projector can be tucked into a large coat pocket and nobody would know.
I was also pleasantly surprised by the number of connections that LG was able to fit into this tiny projector. There are connections for hdmi, usb-a, usb-c (yes, you read that correctly), and a 3.5mm audio out jack. Kudos to LG for including the audio jack because we all know how dismal the audio output from projector speakers in general are. As an aside, Epson doesn't even include a 3.5 mm audio jack in it's conventional projectors until you get to their premium home cinema projector models.
What's also neat about the projector is that you have two choices for recharging the lithium ion battery in the projector. You can either re-charge via the supplied bulky ac adapter with powerbrick, or you can elegantly connect a usb-c cord to a wall charger. Since I like to carry as little with me as possible, I opted to use a usb-c cord and 2.4 amp charger. It'll take up to 3 hrs to charge a fully discharged battery.
Once fully charged and powered on, you simply follow the on screen menus to connect your display either wirelessly, via hdmi, or usb-c. I was able to immediately display content and start using the projector in a minute or two once I familiarized myself with the on screen menus and the remote control. I successfully connected my windows 10 laptop wirelessly through Screen Share and had the projected image of my desktop on my living room wall. I was similarly able to connect wireless displays for my android phones and tablets. I did notice that there is a noticeable lag on the projected image when connected via the screen share wireless display function. When I moved the cursor on my mouse, it took a second for the cursor on the projected image to also move. For a more robust connection, I like going the traditional route of using an hdmi cord and this essentially eliminates any lag which is great for video content.
Speaking of content, I was able to connect my Google Chromecast through the hdmi connection on the projector and turn the projector/chromecast combination into a powerhouse mobile streaming unit. I simply powered the Google Chromecast with a large capacity portable charger (e.g. portable Anker power bank). Add a good quality bluetooth speaker and connect wirelessly through the Mini Beam's bluetooth menu, and you have a totally wireless setup. Outdoor movie nights just became much easier and totally cord free! LG claims up to 4 hrs in battery life when using the most battery conserving eco-options which will lower the brightness of the image. I went ahead and set the projector on best quality and brightest viewing settings (e.g. non-eco friendly options) and was still able to get through a 2.5 hour movie on a single battery charge with battery remaining.
The projector is able to project an HD 1280x720 image with a screen size up to 100” or a little over 8', which is pretty amazing for such a pocket size projector. Image and video quality is as good as 720p can deliver. Colors are vibrant and crisp. Contrast is good. Audio through the internal 1 watt speaker, while better than your average smart phone, still leaves much to be desired and will benefit from connecting to a better audio system through the 3.5 mm audio out jack or through bluetooth. The fan on the projector is remarkably quiet. You won't notice that it is even on when you have audio playing. The projector doesn't get hot when in use; perhaps just a little warm. With conventional projectors, it takes a lot of energy (resulting in heat) to make a bright image. This means that if you are using a conventional projector in a small enclosed room like a small bedroom, you will notice the room warm up. However, with a pico projector such as this LG Mini Beam you won't have the heat issue because it has so little power output compared to a conventional projector. The Mini Beam is great for using indoors in the summer because you won't have the added heat for your air conditioner to deal with.
Besides great features as bluetooth, usb-c, rechargeable battery, a tripod mount, and portability, the LG Mini Beam also comes packed with an automated vertical keystone image correction. Keystone correction will adjust the top and bottom width of the image if the projector is not set up at a right angle to the screen. This prevents the screen from becoming trapezoidal in shape. You will want automated keystone correction since this makes setting up your projector faster so you can begin enjoying movie night.
One other feature worth mentioning is that the projector has 'PJT mode' which flips the image upside down or horizontally. This allows for ceiling mounting for the projector or projecting from the rear onto a transparent screen.
As much as I have been effusively showering the Mini Beam with praise, it is worth noting its one major and significant shortcoming: it can only produce up to 250 lumens of light output. For comparison, conventional home projectors have 2,000 plus lumens, with business projectors having over 3,500 lumens of output. Having more lumens helps to overcome the ambient lighting so that the projected image does not get washed out. With the LG Mini Beam, it is evident that its use is limited to rooms having little to no ambient lighting with blinds and curtains closed. The instant that ambient light is introduced, the image is washed out. I would not recommend the Mini Beam for any type of business use. The office environment has too much ambient lighting. Additionally, an 8' large screen may be insuffficient for large audiences. On the otherhand, this would make an excellent projector for home use where you can control the ambient lighting. It's portability for home use means you can set it up on a table top, counter top, tripod, or even on the bed in your bedroom to watch from the ceiling. For outdoor movie nights, you'll have to wait until it is dark.
In summary, the LG Mini Beam is a fun, easy to use, very intuitive, and high quality portable projector that allows you to cut the power cord. With 720p HD quality, you'll get good to very good image quality which is vibrant and crisp. It comes packed with a lot of features and connections in a tiny package. However, there is a trade-off you'll have to be willing to make for ultra portability, compactness, and battery power. With a small 250 maximum lumen output, you'll need to use the projector in a dark room or at night. Finally, there is the question of price and value that you'll be getting from the Mini Beam. For the listed price of the LG Mini Beam, in today's market you can get a conventional projector with better contrast, better brighness, richer colors, and the same 720p image resolution, but with much more lumens to be able to use in a greater variety of ambient lighting environments. Of course it wouldn't be as portable, lightweight, and cord-free as the LG Mini Beam. These are factors you will have to prioritize as you make your decision on your next projector. Would I recommend the Mini Beam? For home use, yes. For business, no.
