Jun 15, 2020 · We have an old but still excellent Dell 2001FP monitor which we are trying to connect to an Asus Zenbook UX391FA (USBC) using a Dell WD15 docking station via a VGA cable. Unfortunately, we are unable to get the full (1600x1200) resolution on the monitor, it only seems to work well with 1024x768. The laptop is running Windows 10 (64 bit).
