Just a week ago, Barco pleased users in the simulation area with the presentation of a high-brightness QXGA projector, now the Belgians have announced new QXGA units. The common denominator of the new Galaxy series is 4K HD resolution, this time with 4,096 x 2,160 pixels. The 3-chip DLP trio commands a contrast ratio of 2,000:1and is aimed at the virtual reality market.
The model designations 4K-12, 4K-23, and 4K-32 do not only allow a conclusion to the native resolution, but also contain a reference to the light intensity of 12,000 and 23,750 and 32,000 ANSI lumens. To achieve such a high brightness level, it needs Xenon lamps with 2,000, 4,000 or 6,500 kilowatts.
In many respects a galactic unit: The flagship model 4K-32 with 32,000 lumens weighs around 141 kilograms. (Photo: Barco)
The Barco projectors are 3D-ready and the CLO feature (Constant Light Output) brings the brightness of multiple devices in a multi-channel setup to the same level. The sealed professional lens with a throw ratio of 0.9:1 and zoom function is able to create screen sizes of up to 23 feet. The properties of the motorized lens design incorporate a memory function.
The ultra-high resolution can be realized with DVI inputs, there is also an Ethernet jack, apart from eight very robust and programmable GPIO industry standard ports (General Purpose Input / Output).
