Hello,
There was a brief power outage here at my house and the display port on the Acer XB321HK is no longer working. I've tried different cables and even different ports on my graphics card, and was able to determine the issue is the monitor as my other DP monitor works when using the exact cable and port on my video card as the Acer did. The Acer monitor still works through the HDMI port, but DP does not. The monitor is plugged into my Belkin power strip the and power strip's green light for Protected status is still lit so I don't think the damage was a result of a power surge.
So I guess what I want to know is, will my warranty on this monitor cover this?
