The Gefen ToolBox 4K Ultra HD 8×8 Matrix (GTB-HD4k2k-848-BLK) is a small (about the size of the average hand) surface-mountable alternative to rack-mounted matrix switchers. This HDCP-compliant matrix routes eight 4K Ultra HD sources (on HDMI connectors) to any eight displays with HDMI inputs. Gefen says that resolutions up to 4K DCI (4096×2160@24Hz), 4K Ultra HD (3860×2160@60Hz, 4:2:0 color space), 1080p full HD and 1920×1200 WUXGA are all supported. Deep color, 3D and multichannel digital audio including 7.1 channels of LPCM and HBR (High Bit Rate) formats such as Dolby TrueHD, and DTS-HD Master Audio are also passed through. Gefen Syner-G software’s Discovery and Show-Me features simplify initial IP configuration of this matrix.
Each source can be routed to any display location using the front-panel push buttons or the handheld IR remote control in addition to RS232.
