These two new projectors from Optoma have many similarities, so we will start with those before getting into the differences. Both projectors sport 4K UHD resolution (3840x2160), have the expanded BT.2020 color space for deeper, richer colors than you get with the standard REC709 color space, and HDR10. All of this translates to a beautifully sharp, vibrant image with a lot of “pop and wow” factor for your applications.
Both projectors feature the Texas Instruments DLP chipset with XPR technology, and have installation flexibility, with vertical lens shift, a 12-volt trigger, and their own individual elements that we’ll get into in the next section. The 4K550 and 4K550ST are 3D ready with DLP Link compatibility, with great connectivity in terms of inputs and connectors – the layout is simple, but has everything you need for business and education applications.
There are two HDMIs – a 1.4 and a 2.0 with 2.2 HDCP – so these projectors will work with older HDMI sources and other related devices, as well as newer 4K-capable devices. That, along with a VGA (HD15) input and an S-Video port, makes these projectors great higher-resolution replacement models for aging projectors.
The projectors have the RS232c connector for old-school command, and networking via an RJ-45 LAN port. Both are compatible with Crestron, IP Link, AMX and PJ-Link protocols.
