Good large-screen 4K TVs are usually very expensive, which is why some people are looking at projectors to satisfy their big-screen fix. If you’re in this camp, know that ViewSonic has recently announced two 4K projectors designed for home theater use: the PX747-4K and PX727-4K.
Sporting largely similar specs, the key difference between the two projectors is that the PX747-4K offers 3,500 ANSI lumens brightness compared to the PX727-4K’s 2,200 ANSI lumens. Furthermore, both use Texas Instruments’ DLP chip and XPR technology to achieve the 8.3 million projected pixels. Lamp life for both models is rated at 4,000 hours, but goes up to 15,000 hours under the SuperEco mode.
Powered by an “Advanced Image Processor”, the projectors also tout HDR and Rec. 2020 compatibility. According to ViewSonic, the PX727-4K uses an RGBRGB color wheel and covers 96% of the Rec. 709 color space.
Additionally, both projectors come with two HDMI inputs (one of which supports HDCP 2.2) , as well as a 5V/1.5A USB port. The latter can be used as a power source for HDMI-equipped dongles, such as Chromecast.
The ViewSonic PX727-4K and PX747-4K will be available locally for S$2,488 and S$2,588 respectively.
