The Optoma ML750ST is quite clearly designed for portability, and at just 0.42KGs it is an easy addition to your luggage or for using at home and packing away when not being used. The HDMI port on the ML750ST also supports MHL (Mobile High Definition Link) so you can use a single cable to run from the projector to Micro USB on your smartphone or tablet and it will mirror what is on the screen. At 800 lumens, you are not going to get a massive screen as it would appear too faint and hard to see. You will be looking at 1m wide maximum. You can also forget the hassle of having to change lamps around with an ultra-long lamp life of up to 20,000 hours. Because it is only 800 lumens then don’t expect it to be ok for more than 5 peoople audience or you might think it’s a good choice for your home, maybe for connecting up to a games console for a bigger screen experience, or showing off some pictures to the friends and family straight from the MicroSD or USB connection or alternatively show off a business presentation to a couple of people. You will have to have all of the lights off and blinds closed when projecting as it is simply not powerful enough to project when the room is light. The ML750ST is natively widescreen so you can be safe in the knowledge that the movie or pictures you are showing will not have to be stretched to fill the screen. It has a fixed short throw ratio of 0.8:1 so if you want to make the screen bigger or smaller you have to move the whole projector. There are other very light projectors out there that are more powerful, give us a call and we can find one to suit you. The lamp life on LED projectors are there to dazzle you but in truth most people buying this projector would not run it 24/7 so don’t get caught up in the hype, buy it because you travel a lot, don’t have much room and fancy a projector with good connectivity. LED does work well in portait mode but feel the brightness won’t be enought for larger displays.Very rare to get a short throw, portable & LED. Remember short throw don’t work will with mobile or non tensioned screens.
