"Why settle for 1080p resolution when for a few hundred dollars more, you can acquire a projector that offers 4K UHD resolution with 3200 Lumens brightness? The ViewSonic True 4K UDH Home Theater Projector can project movies, TV shows, or game content, for example, to a screen up to 300-inches (diagonal) in size. Combine the higher resolution with good brightness, a high contrast ratio (12000:1), and a 240Hz refresh rate, and your home movie experience will be a memorable one from the second each movie you watch begins."
Projector Central Review
"ViewSonic's PX701-4K, released in February 2021 and currently available at an attention-grabbing $900 street price, is the least expensive 4K/HDR home theater projector you can buy and a great value play for those seeking a late-generation 4K gaming projector. To begin, it's equipped with the latest DLP imager to enable low input lag down to 4.2 milliseconds with 1080p/240 Hz signals (or 16.8 ms for 4K/60 or 1080p/60). It's got a long-life, 6,000 hour lamp in Normal power mode driving a relatively high 3,200 ANSI lumen brightness rating, and a modest 1.1x zoom lens along with a few extras like four-corner correction and automatic vertical keystone for quick setups. Not surprisingly given the price, it does make some sacrifices in its range of connection ports and the lack of some features like frame interpolation and 3D playback. And even after calibration, colors weren't as accurate as on some other budget projectors. But its generally good image quality and low price make it a great option for someone breaking into 4K. "
IGN Review
"This 4K projector is great because it doesn't have to sit far back from your screen. With 3,200 Lumens and 4K UHD resolution, you can see every vivid detail and color on up to a 300-inch screen."
