SX [Master] 4K

A few years ago, full HD resolution was still state of the art for LED displays. Today UHD, 4K and HDR are here, ready for transmission and display. Our answer to this market development is SX Master 4K, the new LED controller for S[quadrat] and NEC displays.

When UHD came into play, not only resolution increased, but new color formats established, that are providing up to 12 bit color depth, wider gamut and high dynamic range (HDR). SX Master 4K was designed to support these formats at best, resulting in brilliant colors and high image fidelity.

SX Master 4K is providing high bandwidth input and output connectivity. Based on DisplayPort 1.4a standard, HBR3 rate provides 25.92Gbit/s, offering 4K or UHD input resolution at 60Hz and 12bit color depth. The DisplayPort output is actively managed and can provide a loop through of the input signal, a modified, cropped and overlaid input signal or a copy of the local control user interface, see below.

Output connectivity is based on SFP/SFP+ modules. The 16 SFP/SFP+ cages provide slots for up to 16 Gigabit Ethernet SFPs (either copper or multimode/singlemode optical) or up to four 10-Gigabit SFP+ modules (multi-mode or singlemode) and up to 12 Gigabit Ethernet SFPs. The content output bandwidth is more than 30GBit/s, not including the bandwidth available for supporting redundant ring topologies to support failsafe operations. This outstanding performance makes one single SX [Master] 4K control a full 4K/UHD LED screen at HDR color depth and up to 24b LED greyscale resolution.

SX [Master] 4K is a one stop solution for LED control. Its integrated 7”-TFT touch and an additional jogwheel allow full system control without using an external control PC. Powered by a Linux operating system, SX [Control] software is providing a featurerich user interface for screen setup and operation. An outstanding new feature is a live view of the input signal on full screen or single module level, so you see what you get. Using SX [Master] 4K’s front panel USB connectivity, external mouse and keyboard help operate and save/recall configurations on USB sticks or hard disks. SX [Master] 4K’s user interface is available for remote control through a Gigabit control ethernet interface using VNC clients after authentication.
