Westar announces the EZwindow4KE Video Combiner

Oct 7, 2020 | Press Releases

Saint Charles Missouri, Oct 7, 2020 – Westar Display Technologies, Inc., a supplier of video processing components and LCD controllers, has added the EZwindow4KE to its video combiner product line.

The 1U rackmount EZwindow4KE is Westar’s latest video combiner supporting one input up to 4K, plus up to 4 other inputs at lower resolutions. With a broad range of window sizes and locations, plus the ability to key one video plane with another, the EZwindow4KE is ideal for an instructor monitor showing multiple displays on a 4K TV, or combining HUD imagery with a 4K out-the-window projector feed. The 4K I/O can be either HDMI 2.0 or DisplayPort 1.2 at a full 4kx2k/60 Hz. Input cards for lower resolutions (2560×1600/60Hz or below) support many video formats, including DisplayPort, DVI, analog RGB, composite NTSC/PAL, RS343/RS170, and more.

The EZwindow4KE features the lowest latency possible on the 4K input (less than 1 msec) and other inputs have a latency of 20 msec or less. If the 4K input is not used, the output can be gen-locked to any one of the input cards, minimizing the latency for that particular input. Each of the lower resolution inputs have automatic mode detection to react to a change in the incoming video format, such as a DisplayPort input transitioning from 720P to 1080P.

EZwindow4KE is ready for delivery and includes the EZwindow4KE Configuration Utility, a PC-based application to help customers configure the unit for each unique application.
