Some things that will help right off the bat: The bluetooth function is for sound output only, there is no file or document transfer capability, presumably because the device does not have on board storage. Pertaining to the wireless screen share option, according to the LG website (in the small fine print at the bottom): ¹Wireless connectivity only supports devices running Android and Windows operating systems, I believe on the Amazon listing only mentions Android. If you have an iPhone or iPad or anything iOS and you are attempting to screen share on this Projector it does not work. You CAN however, use it for a display for your Apple TV (HDMI) or computer (mac with the HDMI to thunderbolt dongle $8 Amazon Basics), and as mentioned in one of the other reviews, if you purchase a lightning to HDMI dongle from apple you can work your iPad or iPhone through the display that way for around $39.99 (Amazon price). You could probably find a cheaper route but be aware that knock off cables can fry your equipment. With the USB function you can watch .m4v or .mp4 movie files (which you would usually find with iTunes) this is a plus if you have to travel because its very portable you can throw a few movies on your keychain USB, plug it in and the kids can watch wherever need be. On the other hand I attempted to read files off my external hard drive, plugged by way of the USB port, and found that it would not read. This could be due to the fact that it is formatted for an iMac or possibly because the files are buried within too many subfolders. Either way a main folder shows up with nothing accessible. I am sure as more people purchase the unit they can provide their experiences as to whether or not they were able to read files directly from an external hard drive. Finally, I gave the device 4/5 stars despite its various limitations because overall, it an excellent addition to either your home entertainment or business ventures. LG devices are well engineered, this one is no different. It is highly portable, has a very friendly user interface, excellent remote, and though its likely not many people have white and gold home entertainment equipment, it really wasnt an issue for my purpose. I purchased the device for my sons room to play video games and watch movies, I was concerned with the low lumen rating (150) but its not an issue, my 2000 lumen Hitachi is not much brighter and the difference in image between the 1080/720 and 1080/800 is not noticeable. It is far quieter than my older and much more expensive projector, and uses LED technology which has a MUCH longer bulb life. I added a cheap 2.1 set of Logitech speakers and his old PS3 and it works great for him. He will never know the days of a 12" RCA and squinting to see anything at all.
