It looks like the 19" monitor may have failed. Can you test it on its own on another system?
Before you do, delete it from this system, close down the computer, turn off the monitor and unplug it from the mains, before connecting it to the other computer.
If it works there, try re-connecting again to the first computer and set up a dual monitor again.
Any LED's on this monitor, and if so, do they light up? If not check the fuse in the plug.
i have 2 monitors a 22inch wide screen and a 19inch lcd i had both of them working perfectly fine before today when i disconnected my 22inch to fix a few cables behind my desk and when i connected it back up my 2nd monitor (19inch) wont display anything all i have is a black picture. the computer is detecting the monitor and the monitor is on but im not getting any picture on it
i have already tried
restarting pc (5000000 times)
adjusting the settings
i just dont know what to do now
i do have the CCC but it detects my monitors and tells me there functioning right but still no picture in my 2nd display
