Windows 7: PC Monitor "No Signal Detected!"

10 Jul 2015   #1

Microsoft Windows 7 Professional 64-bit
PC Monitor "No Signal Detected!"

Hi, my monitor does this weird thing where it works perfectly fine,
but when I turn it off and back on for whatever reason it doesn't work anymore,
"No Signal Detected!" it says...
I would then have to go through the process of disconnecting the display port cable and reconnecting it (or something along the lines of that) and it'll turn back on that way,
what is this, how do I stop this??
The reason I'm creating this thread is that now I can't get that monitor to come back on, period.
Does anybody know how to fix this?!

*Yes I have checked that the monitor is on the right channel, being display port.*
*No the cables aren't loose.*
*No the cables aren't damaged/faulty.*
*Yes I have tried turning it off and back on.*

Well, it could be a few things:

1. Your display port is borked. Have you tried a different method of connecting? DVI or HDMI?
2. Your graphics card has failed completely.
3. Your monitor display port has failed.
4. The monitor has failed entirely.

The first thing that I would do is to try another monitor on the computer and see if it works, if you have access to another one.

None of the above aha, I should mention that I have a twin display setup.
The 2nd display I have works perfectly fine, nothing really to say about it other than that.
Oh It's connected via VGA.
The display port is fine, if I were to describe it I'd say it's more like a software issue than a hardware.
It's odd to explain, it turns on fine, I just have to turn it on a certain way whenever I turn off the monitor while the system's on.

Does the monitor show in Screen Resolution (right click empty desktop area and select from menu) when you turn it off? Does it show after turning it on? Perhaps it is disabled within Screen resolution.
