shahjapan :
follow the steps, I'm sure that will work.
I restarted the system, mean while I have deactivated DDC / CI from Monitors' Settings Menu, then un-pluged My Monitor from CPU, and when I restarted the OS and pluged the Monitor I found the resolution 1440 x 900. Great Work,

Amazing, this fixed my problem too, so rare that these kinds of workarounds work so well!
I followed the above instructions, to clarify the procedure that worked for me, after rebooting I deactivated DDC/CI from the Acer menu (use the "menu" button), then I unplugged the cable from the computer, then unplugged the power cable from the socket. Then I rebooted the computer, and then I plugged the power cord back into the power socket and then reattached the VGA adapter to the computer (this was a laptop).
After that the 1440 X 900 resolution was back and working!
