Optoma UHD55 DLP 4K UHD 3600 ANSI lm Projector, White

The Optoma UHD55 is a standard throw projector that utilizes DLP technology to produce a native 4K UHD (3840 x 2160) image. It is rated for a brightness of 3600 ANSI lumens, making it suitable for use in rooms with some ambient light. The unit's typical contrast ratio is 1,200,000:1, which contributes to depth in dark scenes. Its native aspect ratio is 16:9, aligning with standard widescreen content formats for home cinema applications.

For content compatibility, the projector supports High Dynamic Range formats including HDR10 and HLG. This allows it to display a wider range of color and luminance information from compatible sources. Connectivity is handled by two HDMI 2.0 ports, which support 4K signals, alongside three USB 2.0 ports for media playback or powering streaming devices. An integrated 10-watt speaker provides basic audio output without requiring an external sound system.

Installation flexibility is provided through a manual 1.3x zoom and a throw ratio of 1.21–1.59:1, allowing the projector to create a large image from various distances. Manual horizontal and vertical keystone correction aids in aligning the picture geometry on the screen, compensating for off-center placement. The internal lamp-based light source has a service life of up to 15,000 hours in its standard operating mode, reducing the frequency of replacement.
