RGBlink D4 Multi-format 4K Presentation Switcher

The D4 is RGBlink's modular answer to the mixed-signal presentation room: a 4K switcher and scaler whose I/O you specify rather than accept. Four card slots split two for input and two for output. The input side takes up to four sources from optional 4K HDMI (four HDMI-A, two in and two loop), DisplayPort 1.2 (two DP) or SDI (four BNC) modules, so a 12G-SDI camera feed, a DisplayPort laptop and a legacy 2K source can all land in the same frame and leave scaled to a common output format.

Output is dual-channel 4K HDMI 2.0 as standard, and the two output slots take up to eight outputs total, with option cards for DisplayPort 1.2, 12G/6G/3G/HD/SD-SDI, fiber and HDBaseT when the destination is a long run or an LED processor. Processing is 12-bit internally with 10-bit YUV 4:4:4 color, HDR10 and HLG are supported, HDCP 2.x is honored, and 4K EDID management is built in. It will splice up to 8K x 2K across outputs, which is where the D4 crosses over from meeting-room scaler into LED wall duty.
