The Viewsonic PX749-4K is a brilliantly bright projector that should appeal to price-conscious gamers and film fans alike. The only thing we would have liked to see is frame interpolation.
Thanks to its enormous light output, the Viewsonic PX749-4K is ideally equipped for living room cinema and even more so for the occasional game. It has enough brightness reserves to bring even UHD films and games crisply to the screen without making too many compromises in terms of colour fidelity. In addition, the signal processing sets standards in terms of gaming.
