Samsung S24D300 secondary monitor black screen

Hello,

Two months ago I got a secondary monitor (Samsung S24D300) for my laptop (Toshiba Satellite c55). Setup was a breeze, and I had everything up and running right away. I have had no problems until this morning, when I sat down at my computer this morning, and found the Samsung monitor was black.

The monitor itself is on and functional (the monitor's menus are navigable), set to HDMI input, and plugged in to my laptop via HDMI; laptop display settings are set to "extend display." I can still "guess" at where things are on the black screen, and click and drag to/from my laptop screen. I checked drivers for both the monitor and graphics card, and both are up to date.

Any ideas?

Thank you!

• Hi...
  Some Problem Solving Techniques.....
  1- Make sure the power cord is connected securely and completely at the monitor and at the electrical outlet.
  2- Some Samsung monitors have another power switch at the back in addition to the power button on the front. If there is a power switch at the back of your monitor, make sure it is on, and then press the front power button of the monitor.
  3- Make sure that the signal cable between your monitor and computer is connected securely and completely to the back of your monitor and to your video card.
  
  Press the Auto Adjust button on your monitor. This will adjust your monitor to the incoming signal and may give you a picture and let you reset the refresh rate and resolution in regular mode. If you do get a picture, follow the directions immediately below to change the refresh rate and resolution.

Thanks very much for your reply!

The problem seems to have resolved... I unplugged all cables and turned everything off, then left it for awhile. When I reconnected cables and turned everything back on, the monitor worked fine. It's a little irritating to not know what the problem was, but for now I'm not complaining.

In any event, thanks again for the reply. If my screen blacks out again I'll keep your tips in mind.
