I moved my Sony desktop computer and my Acer AL 1912 TFT monitor into a different room.
Now when I turn on the computer with the monitor switched on - instead of the monitor booting up, an error message comes up saying "No signal". The green (on) light switches to orange (standby).
I have tried checking the connections, using compressed air to clean them. I have turned off and plugged out the computer and the monitor. I even bought a new cable to see if that was the problem. Nothing works. Every time I reboot the computer this happens.
all the best
