Hi guys, I almost spent the whole day going through various online fora on how to remove the annoying 'entering power save mode' response I was getting from my dell P2312H monitor connected to Windows 7 Dell Latitude E5410. I did all what has been suggested but finally went to device manager and located the graphics card name -right clicked and updated the driver. It worked for me, after a good number of hours experimenting what others suggested in vain.
Cheers
