i have tried holding down the menu button for 15 seconds and the menu does not unlock. what other solutions are there aside from sending it back?

thanks,

i am saju,

If you number the buttons from the top 1 through 6 -

* Press button #5 for 15 seconds to activate the padlock feature

* Press button #5 for 15 seconds to unlock the padlock feature. While doing this the padlock will disappear. You must continue to hold the button #5 in until the unlock padlock appears

Bamykhoo,

Try this -
* Turn the computer and monitor off
* Disconnect all monitor cabling from the monitor (power, USB, VGA, DVI, etc.)
* Press and hold in the monitor power button in for 5 seconds
* Reconnect the monitor to the computer
* Reconnect the monitor power cord to the monitor
* Turn on the monitor, then the computer
* Press the Menu button for 15 seconds to unlock the padlock feature

Hi Chris,

I just tried that and the previous steps you listed here and it still does not work for me. I was previously using the DVI-D connector but bought a MacBook Air that does not have that port. So I am now trying to use the displayport using a displayport-mini-dp cable. Does the monitor not autodetect the cable and switch the port? I need to be able to change the input but its locked and will not let me. Any other suggestions? Thanks.

Yoose,

Pressing the menu button for 15 seconds should unlock it? Did you try this?

Chris. Yes i did. I figured out my problem. I had disconnected the DVI-D cable that I was originally using and was trying to unlock connecting with my displayport cable, but I guess the monitor was looking for the DVI-D cable and that had to be connected for it to unlock.
