Q: Input Signal Out of Range!

I have my Macbook Air hooked to an HP Pavilion 27xi Display. It has been working fine. Now when I close the Macbook Air the monitor displays "Input Signal Out of Range!" So I tried to go into the display settings and make changes, but I can't get it to work.  If I leave the laptop open it will work.  I do have the laptop plugged into the power cord. I know that has to happen to make it work.

 

Please help!! Thank you!!
