The only issue I had was the cable to the computer as my computer doesn’t have a hdmi port so I tried the display port using my old cable but it still didn’t work so I had to drive around to a few shops to find one that sells a display port cable
And finally got a new one and everything worked again so it wasn’t the people who sold me the monitor it was my old cable that was the issue so I am very happy with the monitor and the picture quality.
