Take in impressive visuals in true 4K clarity supporting HDR/HLG or upgrade your gaming experience to the next level with 4.2ms Ultra-Fast Input and 240Hz refresh rate. Project an up-to-300” big screen on any surface easier than ever with powerful warping, auto V keystone, H/V keystone and 4-corner adjustment. In addition, the energy-efficient 20,000 hours long lamp life gives it an even lower total cost of ownership than the typical lamp projector. In addition to the stunningly detailed images that true 4K resolution can offer, the projector also supports HDR and HLG content to produce more dynamic-looking images and bringing flat images to life with more displayable information in the darker and brighter parts of a scene. With 4.2ms Ultra-Fast Input* and hyper-responsive 240Hz refresh rate, plus the microsecond-level response time**, you can game with low delay and seamless viewing of fast-moving objects that would bring your KDA to the next level. PX701 can provide perfectly shaped images with comprehensive H/V keystone and 4 corner adjustment capabilities. The auto V keystone further frees you from manual adjustments no matter how you tilt the projector, up or down. With advanced Projector Warping Tool, the distorted image can be perfectly shaped through multiple point adjustments, even when projected on a spherical shape, a cylinder, etc. The latest SuperEco+ mode technology greatly extends the lamp life of the projector from 15,000 hours to 20,000 hours – meaning 4 hours a day for more than 13 years – saving you maintenance cost and effort. ViewSonic Projector Software Update is available online and enables you to keep your projector firmware up to date easily and conveniently with your laptop and USB cable connection; no need to take your projector into a service centre for software updates. The projector is embedded with a 10W speaker to deliver satisfying audio performance right out of the box. A built-in USB power output (5V/1.5A) can be used to supply power to HDMI wireless dongles, like Chromecast, Amazon Fire TV stick, etc., eliminating the need for separate power adapters when streaming your favourite multimedia content.
