When I turn on the monitor, I get an error message: "Warning PC entering power saving mode", then it turns off.


Unplug your dekstop from the electricity then press and hold the power button on your desktop for couple minutes with out no power cable attached to it then let go of the power button then connect your desktop back to electrical outlet and press power button once that should give you display once it turns back on you can go into your power saving options and turn off power saver mode as its conflicting with your LCD sometimes this can occur if you have Norton antivirus installed
if after doing the power drain and still get same message then you can try using a different monitor if you have one for a test.
this issue is not with your monitor but with the PC has been stuck in sleep mode but the power drain should solve your problem.

Before Windows can boot-up the screen turns solid blue & a Dialog Box state "Entering Power Saving Mode". The screen then appears that the sleeping mode has occurred.

Monitor displays "warning pc entering power saving mode


Hello
Sounds like to power settings were set too low. Restart the PC, before it gets to Windows press F8. This will send the PC into SAFE mode. You'll get a menu of which SAFE mode to select, just select SAFE mode with networking. Once in SAFE mode, go to START, Control Panel, Power Options. From there select new settings. Since this is a desktop, I would make the settings very long. Good luck

Monitor shuts off during boot. Let the machine boot full up, hit the power button, the monitor flashes windows for a split second, and goes back to power saving mode


Hey there Celius,

Chances are the 'Refresh Rate' somehow got set too high for the monitor. On flatscreens , the result is a black screen.

If you have an old monitor (crt type) hook that up temporarily and reboot.
  • Right Click the Desktop
  • Click Properties
  • Click Settings
  • Click Advanced
  • Click Monitor
  • Lower the refresh rate or set at optimal
  • Check the box 'Hide refresh rates this monitor can't display'
Shutdown, Switch back monitors and try it now.

Good luck
Mike
