Hello all. I am having trouble with my E228WFP. Just for the record, I can lock and unlock the monitor (hold down menu key). The issue has nothing to do with that. The issue is rather that it seems like the - and + buttons don't work. All other buttons work though. As a result of my inability to use the + - buttons, I cannot navigate the OSD menu or use the quick adjust mode of pressing the + or - keys directly.
I am connecting the monitor via analog vga connection and the image shows up perfectly at 1680x1050... problem is I can't calibrate the image anymore than that.
Please advise if there is a solution :).
One last thing... the monitor did pass the self test and I only tested the above issue with an analog (vga) connection. On my new and old laptop in both windows and ubuntu.
* Power off the monitor* Disconnect the power cable from the monitor* Disconnect all monitor cables from the PC (USB, DVI, VGA, DisplayPort, HDMI, etc.)* While disconnected, press and hold the monitor power button down for 5 seconds* Reconnect the video cable to the monitor and to the PC video card* Reconnect the power cable to the monitor* Power on the monitor if it does not power on by itself* Power on the PC* Press the monitor Input Source Select button for your cable* Once into windows, test the monitor +/- buttons. If still no go and under warranty, get it replaced by Dell
