My first monitor popped up no rgb input and shut down. will come back on if wait awhile. never know when it gonna shut down on you. I have a new monior now. Its the hP 2009m model. when it goes to shut down it pops up monitor going to sleep and shuts down,
I just bought a 20 inch HP 2009m monitor about 2 months ago.
One of the functions within the monitor, is to go to 'Sleep'
The Sleep mode is to keep the monitor active, but using very little power.
(I always turn mine off when I'm finished with the computer. More longevity for the monitor, and less electricity used. With today's economy every little bit helps)
You can set a desired time for the monitor to go into Sleep mode, or you can disable this function. (Off)
Factory setting is supposed to be set to Off, to my understanding.
You can view what the Sleep setting is, while you are using your monitor. The monitor has on On-Screen menu.
(OSD. On-Screen Display)
To the left of the Power On button, (Lighted when the monitor is on), there are Four function buttons.
These are located right under the bottom edge of the monitor.
One is located right under where it states - Menu
One is located right under the combination speaker symbol, and Minus - symbol.
One is located right under the combination Source, and Plus + symbol
The last button is located right under the combination Auto/OK
When the On-Screen Menu is activated it, is a small window.
You will still be able to view around it.
However, you may find it best to write the following instructions down, as you may not be able to view them here, and also the On-Screen menu.
1) Press the Menu button up.
The On-Screen main menu will now be visible.
2) In the list given you want Management.
Use the Minus ( - ) speaker button, to move the highlight down to Management.
3) With Management highlighted press the Auto/OK button.
4) In the Management sub-menu where you are now, you want to choose - Sleep, in the list.
Use the Minus - button, and move the highlight down to Sleep.
5) With Sleep highlighted press the Auto/OK button.
6) In the Sleep sub-menu view across from Timer.
Is ON highlighted?
Plus is there a time set?
If you wish to turn the Timer off:
Use the Minus - button to highlight Timer.
Press the Auto/OK button.
Now press the Minus - button, and highlight OFF.
Press the Auto/OK button again.
Save and Return at the bottom of the list should now be highlighted.
Press the Auto/OK button.
This will take you back a screen, and you should now see Exit highlighted.
Press the Auto/OK button.
Your monitor is now set to have the Sleep mode function shut off.
Should like to hear the results of this.
Looked at your problem again, while I'm waiting for the results from you. (Just click on Comment)
Your problem looks more computer related to me now.
Do you have access to another working computer? A friend, or relative perhaps, if you do not have another one?
Hook up your old monitor to it, and tell me what happens. Does the monitor work okay?
Then the problem is the computer.
It also sounds like it's the computer do to the same thing is relatively happening with both monitors.
No video signal from the computer to the monitor.
No RGB video signal, and the other monitor goes into the Sleep mode.
I also believe it's a hardware issue with the computer, and not software related.
If the computer is dirty inside, as well as the Power Supply, chances are the power supply has developed a weak voltage power rail.
And/or it could be something as simple as the Processor fan, and Heatsink are dirty, and the processor is shutting off.
Computer hardware components inside the computer are kept cooled off by air. Air flowing through the computer case, from the computer case fan (Or fans) drawing air in, and the Power Supply fan drawing air out.
Dust, Dirt, Lint, Hair, Food Crumbs, you name it is drawn into the computer. Even if a person is the best housekeeper in the world.
For this reason computers need to be cleaned out on a regular basis.
There is also a fan which sits on top of the Processor. The Processor has a Heatsink sitting on top of it, and the fan sits on top of the Heatsink.
A typical Heatsink is a flat, thin block of metal that has tall thin fins that extrude from it.
Heat is absorbed by the fins from the Processor, and pushed away by the fan.
(Same principle as a car radiator, or house radiator, except no water is used)
Once the Heatsink fins, and the blades of the fan, become clogged with the above mentioned foreign material, the cooling capacity drops tremendously.
Same thing with the computer case fans, and the Power Supply fan.
This leads to the Processor overheating, and the Processor shuts off.
No Processor, no computer. No computer, no video signal to the monitor.
The monitor goes into Sleep Mode, or states no RGB Input.
Once the fan blades of the Power Supply fan become clogged, the cooling capacity drops tremendously.
The Power Supply heats up.
Heat = Wasted Energy
The Power Supply then tries to make up for the amount of power being lost, and eventually fails.
Components inside the power supply fail.
Generally the Electrolytic Capacitors are the first components to fail.
This cause a weak voltage power rail inside the Power Supply.
The Power Supply cannot produce enough power for the Processor.
If the Processor is running it turns off.
If the Processor is not running it never turns on.
One more item.
Electrolytic Capacitors can also fail on the motherboard. This is Visual Signs of Capacitor Failure.

Hmmm is it your monitor going to sleep..or the machine? might the computer still be running?
if it's the computer go to power setting and change to your pref
