The Gefen EXT-4K300A-MF-41-HBTLS is a 4x1 Presentation Switcher with HDMI, DisplayPort, DVI, and VGA inputs, along with an L/R analog audio input that accompanies both the DVI and VGA inputs. It features split HDMI/HDBaseT outputs, and a de-embedded analog L/R audio output. The 4 inputs can be switched automatically or manually. Control options include the front panel, a hand-held IR remote, electrical IR, RS-232, and contact closure. The split HDMI and HDBaseT outputs can simultaneously feed a local and a remotely-installed display, adding flexibility in larger presentation environments.

The HDMI and DisplayPort inputs support resolutions up to 4K 60 Hz 4:2:0, with HDCP 2.2 and 1.4. The HDMI input and output, and the HDBaseT output support up to 7.1 channels of highest performance LPCM and HBR (High Bit Rate) lossless digital audio, such as Dolby Atmos®, Dolby® TrueHD, DTS:X, and DTS-HD Master Audio.

The DVI and VGA inputs support resolutions up to WUXGA
