Really? Oh man...I'll check my return policy and see what the max is. Other than the pixel shift thing I am really happy with the monitor.
I was able to do that the first time, but the last few times I tried that it screwed up my other monitor that is connected via HDMI and had to reboot. A guy on Reddit mentioned I should try the big power switch on the back to reboot the monitor. I just tried that today and it did not help (XB270 went into power save and my second monitor got all flashy and broken). I wonder if it is a cable or video card/driver issue because when I turn the monitor on the Acer and Energy star logo look fine but when it switches to using the displayport is when it looks messed up.
