I have used my new Acer EB321HQUC (32", 2560 x 1440 pixels) as the primary monitor for my Surface. Unfortunately, I have flickering on the screen despite the shielded HDMI cable. I have tried different resolutions, unfortunately without success.
What else can I do?

Answer

Check the suitability of the docking station, the USB hub, etc.. I am using two Acer EB3321HQUC 32" monitors of the same type at two locations, each without flickering and with correct resolution, in combination with a Surface. At location 1, an official Microsoft Surface docking station is in use, at the other location a Targus DOCK430EUZ docking station.
