“Time was when £300 in the projector world wouldn’t have got you much more than a box that fired light at a wall. The H183X, however, turns out to be a surprisingly effective home-entertainment device.”

“By far the most pleasant surprise is the H183X’s black-level response when watching video sources.”

“The H183X also impresses with bright scenes. Given the claimed 3,200 lumens of maximum light output, I guess this achievement is less surprising than the decent black-level response.”

“Optoma has managed to deliver easily the best sub-£400 home-entertainment projector I’ve seen.”
