What people are saying

Rated 1 out of 5 by from Less than 3 years, it's stopped working Expected more from LG. Unfortunately it stopped working. It shows to have been manufactured in Sept 2019. I also had a LG Nexus 5X be stuck in a boot loop defect after 1 year. Bad experiences with LG products' durability. I still have a working Acer Acer H5360 projector that is almost 10 years old, and still working great. My experiences with LG have to been very disappointing thus far.

Rated 4 out of 5 by from Perfect for a multitude of uses. I bought this for movie night. After using it we determined we can use it anywhere, in the house, camping (project it on the side of our camper) I plugged in an amazon firestick.

I have been trying to get a more seamless Audio-Video sync between my bluetooth audio and video from this device, any advice as I have not been able to get this perfectly matched as yet?

Asked by: Omesan
Hi Omesan. Unfortunately, Bluetooth is known for having lag, audio latency or Bluetooth audio delay, and if the Bluetooth version for the LG Ultra Short Throw LED Projector with Embedded Battery, Model # PH450UG is not the same as the device that you have paired with the projector, you will experience a lag between the video and the audio. The other issue is that if there isn't enough bandwidth to support a particularly large audio file transmission (e.g. you're listening to a lossless audio file), then the transfer won't go as fast and smooth, and this will reflect as audio stutter and lag. What device are do you have the projector paired with? Bluetooth headphones and earbuds experience at least 32ms of audio latency. But that's only in ideal circumstances. You're more likely to run into a 100-300ms delay, especially while using true wireless earbuds. There is an Adjusting AV Sync. Adjust setting in the projector that will help. When a Bluetooth device is connected, go to → WIRELESS → AV Sync. Adjust to adjust the synchronization between the video and the Bluetooth headset sound. This feature is only available when a Bluetooth device is connected and Audio sync will vary by manufacturer...^IFV

I seem not to be able to use the screen sharing option from a windows PC and Bluetooth audio out. When screensharing only the inbuilt speakers or audio jack out work. Is this normal?

As I know this projector does light with some angle (not direct light). I am going to use projection screen. Could you please provide details: what difference in height has to be between projector and bottom line of an projection screen if distance is 1m?

Asked by: tarasshpek
The distance between the Ultra Short Throw LED Projector with Embedded Battery, Model # PH450UG determines the actual size of the image and the projector should be positioned so that the lens is at a right angle to the screen. The projector has a ratio of upward projection of 120%. Keep in mind that this is a Short Throw Projector so to maintain an Aspect Ration of 16:9, the furthest that the front of the projector can be from the screen is 330 mm (.33 m) and the distance between the plane that the top of the projector is on and the bottom of the screen will have to be 169 mm (.169 m) and the distance between the bottom of screen and the surface on which the projector is placed on will have to be 260 mm (.260 m). The screen size has to be 2032 mm (1771 mm (Horizontal Size) x 996 mm (Vertical Size)). Page 24 of the owner;s manual has all the details for distance from screen, screen sizes etc., that you can review. You can download a printout an PDF copy of the owner's manual to review it from our site at^IFV

Does the matching upright stand shown in the promotional video (used to project the image onto a desk) come with the projector or can you at least buy that separately - and from where please? 

Asked by: Lucchese77
The owner's manual, a remote control with two 'AAA' batteries, an AC-DC adapter and a power cord are the only included accessories that come with the LG Ultra Short Throw LED Projector with Embedded Battery, Model # PH450UG. Any Consumer Electronics Retailer that carries projectors will carry screens, tripods etc., that you might need and there are some Consumer Electronics Retailers who specialize in projectors and Camera stores that may carry those accessories...^IFV

I have a Logitech Bluetooth audio adapter connected with my audio system whitch works fine with my MacBook. But it is not found by this beamer (after disconnecting with the MacBook) a clue?

Asked by: Iris86
You can wirelessly stream sound directly from the LG Ultra Short Throw LED Projector with Embedded Battery, Model # PH450UG projector to a Bluetooth compatible sound system like home audio speakers, headphones or portable speakers. Regrettably, we are not familiar with the Logitech Audio Adapter and suggest you contact for assistance with getting it to recognize the audio from the projector...^IFV
