Why a 4-input HDMI card?
When an install has several sources — multiple laptops, a switcher, a playback machine — a four-input card lets them all land on one card and be windowed onto the wall at once, instead of constantly re-patching a single input.
This card is dual-mode: run it as 4x HDMI 1.3 for the maximum four simultaneous inputs (the typical choice), or switch to 2x HDMI 1.4 for higher resolution per input when you only need two. Both modes support 10-bit sources, embedded audio and 144Hz.
