Ultra HD brightness for living rooms

The ViewSonic PX749-4K delivers true 4K UHD resolution with HDR and HLG support on screens up to 300 inches. Its 4,000 ANSI lumens output keeps images vivid even with the lights on. A Harman-tuned speaker adds sound without extra hardware.

Gamers wanting fast response

Xbox players get 1440p at 120Hz with 4.2ms input lag, while other titles can run at 240Hz. USB-C lets you stream straight to the big screen. Buyers who need lens shift or motorised zoom for fixed ceiling mounts should look elsewhere.

4.2ms input lag at 240Hz

This single figure decides whether the projector keeps up with competitive play. At 4.2ms the PX749-4K matches high-refresh monitors for responsiveness. If your gaming demands lower latency, this model will not meet that requirement.

Questions about this item

How loud and hot does the PX749-4K get when running for a full day?

The projector uses a high-brightness lamp rated at 4,000 ANSI lumens; extended sessions will produce noticeable fan noise and heat, so ensure adequate ventilation around the unit.

Which cables or devices must I already own to connect the PX749-4K?

You need an HDMI cable for 4K HDR sources or a USB-C cable that supports video output for direct streaming from compatible laptops, phones or tablets.

Will the PX749-4K work with my older 1080p console or Blu-ray player?

Yes, the projector accepts 1080p signals over HDMI and scales them to its native 4K panel, so legacy devices display correctly on screens up to 300 inches.
