After using the monitor sometimes the monitor goes black and a message appears 'input not supported' the computer still runs but I have to shut off the computer and wait a couple of hours before I can turn it on again. I can't find the troubleshoot for this message. The power management is turn off-never and the screensaver is on off as well.
What does this message mean?
I think the probelem is monitor resolution out of range . try the system resolution changes and connect the monitor then the issue is solved 80% or other problem is monitor hardware damages cheack the whole hardware components

after blackout, check the screen as that. look in to the monitor in side angel, and if you can see darken live image in that and its working. in that condition, your LCD panel is working and the problem is no light. in that case you need to repleace or repair the " inverter unit " in that monitor. that unit makes the high voltage for back light.
after blackout , you cant see any darken image like as that, and or totally power goes off , that is different problem. for solve that need advance trouble shooting and can be need advance repair.
Not quite sure what the question is that you have not already answered for yourself.
That monitor's maximum resolution is given as 1440 X 900 at 60Hz and installing a more powerful video card won't change that.
This is the resolution problem. Pls reduce the resolution .
Right click any where on the desktop and click on properties there.
a popup appears just choose Setting there . there you will find the option of Screen Resolution .Just Slide the pointer toward less litlle till your problem resolve.
The problem I have is that when we connect the screen it wiorks fine then blacks out after 5-40min It then flickers on and off iregularly and every now and then shows distortion and eventually just blacks out
I have two 172N monitors and both now show the same symptoms
We have used different VGA cables and different computers in different locations all with the same result
