To avoid screen wash out or the need for 5m of space then you may want to consider short throw projectors such as the Pico Genie M550 Plus, a smart projector which also offers several improvements over the PicoPix such as 650 lumens, a 3 hour battery and wireless mirroring to Apple as well as Android and comes with a tripod in the package.
T3 tech magazine recently reviewed the Philips PicoPix PPX4935 and said
"Don't expect silky smooth motion and inky blacks, but it's seriously good fun and can even be run on its internal battery - although two hours of life makes that more suited to Olympic sprints and boxing matches than games of football" T3.com March 2017
Key features of the PicoPix include an onboard Android OS, Wi-Fi and a 2 hour battery so it is certainly feature-packed and decent value, although not quite on the same level as the M550 Plus.
When wired the PicoPix PPX4935 can mirror the screen of an MHL-compatible mobile device (ie Android devices mainly), as well as having the option to connect Android devices wirelessly via Miracast. You can also connect Apple devices via a wire, using the Apple Digital AV Adapter, although you cannot connect the PicoPix PPX4935 to an Apple device wirelessly without downloading extra apps. It can also connect via HDMI or project content from a microSD card, which is pretty standard these days.
However the PicoPix does lack a VGA port,
Overall, it’s a decent projector with quite a few good features, however at around £475 it is a little pricey when compared to other models such as the Vivitek Qumi Q3 Plus, which offers all the same features including Android OS, 2 hour battery and Wi-Fi. The Q3 Plus however has 500 lumens compared to the PicoPix's 350, which you'll certainly notice in a brighter room, and it is around £50 cheaper. The Qumi Q3 Plus is also a similar size and weight to the Philips PicoPix PPX4935.
While the PicoPix is impressive it isn't as good value as the Qumi Q3 Plus and doesn't offer the extensive features and high performance of the Pico Genie M550 Plus so we would look at those models before the PicoPix.
Like many of the Philips projector range such as the PicoPix and Philips Screeneo 2.0 these models are increasingly difficult to get hold of in Europe and this stock shortage is expected to continue for some months so if you cant get hold of one consider the Qumi Q3 Plus or the really high end Pico Genie M550 Plus
