I bought this U2718Q yesterday. The display looks good for me. However, there is no audio from it: 1. I checked the previous posts, and followed the steps to unplug/plug; unpower/power again. 2. I connected from the Surface Pro mDP out port to the U2718Q DP in port (no audio) I connected from a desktop HDMI out port to the U2718Q HDMI in port (no audio) I checked the cable, replaced the cable. 3. From right click the sound button, when I configure the U2718Q audio, there is no audio coming out.
