Monitor goes into energy save

you may find you have the screen resolution set to high, try changing to 1024x768 and try again. if this works it means your monitor ain't up to the job of your better machines.

there is a weird possibility that somehow your PC is configured to save power.. that is something you can do on a laptop to save battery..
you can check in the control panel what is the status of your energy options and see whats going up there..
there is also another possibility that it might be the monitor to be malfunctioning... but if after the screen being dark and you enter the options on the monitor and they are bright i doubt its a malfunctioning monitor..
so try to reinstall the monitor drivers and possibly the drivers of your video card if you have one.. but my biggest bet would be the option energy in the control panel

try this & see if it helps

Hi there. I had the same problem months ago when I try to play high end games like Sims 3 my monitor goes into power saving mode. I tried to check every possible causes of the problem. It could be that your computer is overheating try to clean your computer and check if your fans still works. Second it could me your power supply malfunctioning, maybe it does not meet the required power to make your game work. Last cause is your video card malfunctioning, what I did is to just buy a new video card and it works.
If you do not have spare power supply or video card you can go to a computer repair shop for them to check the possible problem that causes it to go into power saving mode. It can also save you money before you can buy a new one.
Hope this helps, Have a good day!

you talk about a dell monitor but categorised under LG monitor... if it's a Dell monitor, and its recent, it's possible you've put it in analog/digital mode when you need the other mode. push the left button on te front of your screen that should switch your screen from digital to analog or vice versa

Have you checked you power saving options in Control panel.
If this is a desktop, unless you are a energy miser, I would change your power saving options to never on all options, turn off hibernation and suspension for when you are playing games.
You can find this in control panel under power Options.
Let me know if this helps.
Thank you

I had the same problem with my LG Flatron (not the same model as your one). I fixed it by connecting both the digital and analogue cables from the pc. Presumably, the problem occurs because the monitor is not receiving a digital signal.

Greetings,
Usually that happen once the resolution of your monitor cannot meet the desire need, it depends the kind of monitor that you have even if you change different kind of video card, its still happend.
Try to change the resolution to lower one.
Here's the step
1. right click on the desktop ( a place where there is not icon on your screen)
2. choose properties
3. then settings
4. adjust the screen resolution to lower settings some on the color setting
5. then ok.
Thanks.
