SP4/Surface Dock not sending WQHD to External Monitor I have a BenQ monitor (BenQ GW Series GW2765HT 27-Inch Screen LED-Lit Monitor) hooked up to my Surface Dock &amp; Surface Pro 4. Recently, it is has only been sending 1920x1080 instead of 2560x1440.

Any idea what might be happening? I think it started after the 4/20 update, but may be mistaken.
