Thanks to this kernel of an idea, I've just watched a film on the new Anker Nebula X1, in my garden, projected in 4K Ultra High Definition, onto a 120-inch screen, with a genuinely thrilling 4.1.2 surround-sound speaker system. But I do love the big screen, and in the pursuit of something close to a compromise I have tested dozens of superb portable projectors. But none have come closer to looking and sounding like a proper home cinema than the Anker Nebula X1. Screen TimeThe Nebula X1 can project up to a 200-inch image from between 13 to 22 feet thanks to its optical zoom. This is all done via a single button on the remote control, making it one of the easiest projectors I've set up.
