Monitor Blacks out 'input not supported'

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?

    My monitor blacks out ,only when I want to play a video file. It blacks out several times and either comes up with "NO INPUT" or just freezes.

    Tried a disc cleanup , registry fix, reinstalled win xp.

    Maybe Video Card is faulty?

    Can start up my computer without problems, and find that suddenly, maybe part way through a game, my screen goes black and a message appears, "Input not supported". The only solution is to switch off the main power, and reboot. I can do this straight away, and the problem goes away OK - until the next time it happens.

    Monitor - Acer 19" Norton is up to date, and I run RegCure quite often but it still occurs

My LG monitor blacks out intermittently when warm, I have tried it on another computer so it is a fault with the monitor. It blacks out every few seconds, sometimes it takes longer. It is 2 years old.

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.

My w17e monitor says "input not supported"

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.;psum



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

There is no external influence that we know


Samsung SyncMaster 17" LCD Blacks out

If you have a second monitor, you could use your computer until the monitor goes black... then plug in a replacement monitor. My guess is that one will display black too...

My gut feeling is that your VGA card is on the fritz... I'm not convinced it's your monitor. Do you have a replacement VGA card you can try? I'll bet that'll take care of the problem.
