Possible Solution for Monitor Stuck in Power Saving Mode

Find the manual for your monitor at this site: http://www.dell.com/support/home/us/en/19?c=us&s=dhs&cs=19&l=en. This will tell you how to configure your monitor using the On Screen Display(OSD). I have had my Dell for over 3 years and within the last 2 weeks it would go into Power Save mode and I could not get it out of that mode without shutting down the CPU. I download an update driver but that still did not work. I set all my power controls to never and that did not work. Also when I did download the updated driver, for whatever reason the Catalyst Control Centre would not open so I did a restore back to when it did work however in order to do so I removed the digital cable and used the VGA cable and by doing so it did not go into power save mode so I was now able to get full function of my computer. However, I did not like the display for VGA(analog mode), so I swithched back to the DVI cable inputs which is white. Whenever switching cables it is important to ensure that you CPU and monitor are turned off. Neverthess, after switching back I did further notice that when I started up the computer or switched between users that the display would show a little black box that read "digital input" yet prior to all this happening the black box would read "Auto Detect:Digital Input" so I tried to figure out how to get that back. I found the manual for my monitor and there are 4 settings for the monitor right on the monitor: Analog Input, Auto Input, Digital Input and HDMI Input, so I set it to Auto Input and everything works perfectly now. I even use all my power settings for sleep, hibernate, etc. and have no problem waking it up from power save mode or sleep. However, when I change it back to Digital Input the problem reoccurs, so it is important to use the Auto Input, at least, in my case. As a further I have set my monitor refresh rate to 75 HZ and display to 1024x768. Repost if setting the display to Auto Input works for you so that I will know if this solution works in other cases. Thanks.

On the front and I would say almost every monitor there is a set of buttons at the bottom and one of those buttons should let you cycle through the various input options as I mentioned above. Again, set it on the one that says "Auto". Further, ensure you have only one input cable into your monitor, whether it is VGA, DVI, HDMI  or Displayport. Repost back it this does or does not work.
