Based on LCD technology, the Christie LWU720i-D projects images in a Event environment, with technical specs listing 7200 ANSI lumens, a contrast of 65000:1 and a WUXGA 1920 x 1200 resolution. The manufacturer rates the durability of the included lamp at 3000 hours. The specifications identify the device as a model with an interchangeable lens option. Matching optional optics allow for exact adaptation to the required image size and projection distance, which can be calculated directly with the Lens Calculator. A look at the light output reveals: The 7200 ANSI lumens are sufficient to illuminate an image width of up to 862 cm in darkened rooms. If room light is present, we recommend not exceeding a maximum width of 575 cm. Regarding signal processing, the model is compatible with incoming 1080P content. An additional 360° projection capability allows the device to be oriented at almost any angle. For integration into professional environments, an RJ45 connection is available for network control and remote maintenance. Since entering the market in 2017, production has been discontinued; the manufacturer no longer actively offers the model.
