ViewSonic said this week that it is preparing to ship to retail an aggressively priced high-brightness “4K DLP” UHD home projector, listed with light output of up to 3,500 lumens.
ViewSonic model PX747-4K ($1,400 suggested retail price) uses TI’s special pixel-shifting technology to present what appears to the eye to be a full 3840×2160 pixels displayed on screen at one time, although the DLP Digital Micromirror Device does not carry the full native 4K pixel count. Instead pixels are shifted back and forth very quickly to trick the brain and eye into perceiving all of the pixels needed for 4K resolution at one time.
This same technology has been recently introduced in low-cost “4K DLP” projectors from other brands, including JVC and others, giving consumers a more affordable option for 4K projector ownership.
The new ViewSonic projector also uses exclusive “SuperColor” technology for deep and rich color reproduction and Texas Instruments’ XPR technology that contributes to the unit’s high-contrast (12,000:1) performance.
ViewSonic said the PX747-4K is High Dynamic Range (HDR)-compatible with the open standard HDR10 metadata-based EOTF profile. This produces bright highlights and deeper, richer (1.07 billion) colors.
The high brightness, bulb-based light output enables viewing images in both dark and moderately well-lit rooms, for greater placement flexibility.
