Totevision LED-712-4K2

The LED-712-4K2 puts two 7-inch monitors in a 3RU rack panel and lets both of them accept 4K. Each screen is a 1920 x 1200 TFT LCD at a 16:10 native aspect, running 450 cd/m2 against a 1200:1 contrast ratio, and the HDMI path takes UHD at 3840 x 2160p up to 30 Hz as well as full 4096 x 2160p at 24 Hz, scaling it down to the panel. That is what lets a rack keep an eye on a modern 4K camera chain without needing a 4K screen to do it.

The toolset is aimed at people who actually have to judge an image: vector waveform on RGB, Y, and YUV, a monochrome peaking filter for focus, check field across black, white, red, green, and blue, center marker, safe area, under-scan and over-scan, ratio markers, anamorphic modes at 1.3x, 2x, and 2x mag plus a user-defined 1.2x to 2x, noise reduction, image freeze, image flip on all four axes, and zoom at 4x, 9x, and 16x. Each monitor has an HDMI input with an HDMI output and a composite BNC input with a BNC output, plus RCA L/R audio in and a 3.5mm headphone output. It runs on 12VDC, accepting anywhere from 9 to 24 VDC, and draws 8 watts maximum. The panel measures 19 x 5.5 x 1.4 inches and weighs 6.15 pounds.
