I just bought a D2343P, but when I tried it, the horizontal ( or is it vertical ?) pixel is highly visible ( like a tiny black lines crossing the screen horizontally). I've tried using the D-SUB cable, DVI cable, and HDMI, but it's still there. I've set the resolution on my computer to 1080p, and it's still there. Anyone buy a D2343P, and if yes, do you experience the same issue ? Or is 1080p on 23" is like that ?
