Optoma Launches Two new High Brightness 4K Ultra HD Projectors – 4K550 and 4K550ST

Optoma has just announced two new high brightness 4K Ultra HD professional installation projectors – the 4K550 and 4K550ST.

The new models deliver impressive 4K UHD images at 5000 and 4500 lumens respectively with the short throw lens of the 4K550ST providing stunning image performance from as little as half a metre away.

Designed for meeting rooms, simulators and the corporate sector, as well as for CAD and architectural drawings where brighter, higher quality imagery and complex detail is needed, these projectors enable unscaled 4K UHD imagery.

Philip Watt, Commercial Product Manager at Optoma Europe, commented: “Optoma is the number-one selling 4K UHD projector brand worldwide*. We’re excited to build on the success of our 4K UHD home projection range with the launch of our first 4K UHD professional installation models – the 4K550 and 4K550ST.

“These new models bring the benefits of high brightness 4K Ultra HD and short throw to any professional installation or business presentation. With four times the resolution of 1080p and true to life colour reproduction, these new models offer maximum clarity when displaying text and graphics.”

Featuring an advanced DLP single-chip design from Texas Instruments, 8.3 million pixels are delivered to the screen without the alignment issues found in some other technologies – ensuring absolute image integrity.

In addition to UHD 4K resolution, both models offer High Dynamic Range (HDR) compatibility, and the HDR10 open standard specifically, which means everything from streaming 4K content to game consoles is supported.

The 4K550 features a 1.6x zoom projection lens and both projectors feature vertical lens shift for a quick and accurate installation – without the need for costly interchangeable lenses. RS232C and LAN connectivity enable simple integration and control via industry standards, including Crestron, IP Link, AMX and PJ-Link.
