4K Auto–Switcher/Scaler Receiver over Long–Reach HDBaseT

Categories: , Tag:


VP−427X is a high−performance auto−switcher/scaler receiver for 4K HDMI™ over long−reach HDBaseT and a local HDMI input. VP−427X receives the HDBaseT signal from a compatible transmitter, converts it to HDMI and up− or down−scales the picture to any resolution up to 4K@60HZ (4:4:4) set by the user or automatically matching the resolution of the HDMI monitor. VP−427X enables extending video signals to up to 40m (130ft) over CAT copper cables at up to 4K@60Hz (4:2:0) 24bpp video resolution and provides even further reach for lower HD video resolutions.
