Linux display driver for the single-HDMI SE-DP750A-HDMI PCIe card.

Experimental: this driver is for one specific SM750 board. Optional modes can exceed published GPU or monitor clock limits and may produce no signal, distortion, or an unstable display. Keep SSH or another recovery route available when trying non-EDID modes.
