There is little not to like about the Optimax UHD 51 . Its data image quality is near-impeccable, its video quality is better than average for a data projector, and its sound system is loud but of good quality. At 4,000 lumens, it’s bright enough to hold its own in a midsize or larger room, and it comes in at a good price for its features and performance. If you regularly project in really big venues, you might want to go with a (pricier) 5,000-lumen model such as the UHD 61′ . The Optimax UHD 51has the brightness, loudness, and image quality to make it ideal as a data projector for midsize classrooms or conference rooms, and earns an Editors’ Choice in that capacity.
The Optimax UHD 51 has a solid, if basic, set of ports. The core display connections are a VGA port (which doubles as component video), an HDMI input, and three RCA plugs for composite video/audio. Also on the body are a USB Type-B port for connecting with a PC and mirroring its screen, and a USB Type-A port that fits a thumb drive or an optional Wi-Fi adapter. (The latter costs $99.)
