Hi,

I have a Samsung T220P which was used for not very, but was bought a long time ago when it was relatively new.
Anyway, this happens on two tested computers:
When the computer is turned on (Win 7), the screen shows some flashing thingy, and it always goes away 5 seconds afterwards and doesn't come back until the next reboot.
This problem isn't that important, I can live with it.

The main issue is this: after a few days of having the screen connected to a computer, the screen starts to switch signal sources (Analog and Digital) on its own. It's connected to DVI all the time, so I'm guessing it doesn't get a good digital signal, right? What can be done about it?

Thanks.

Some monitors do this on their own checking for signals. Or it could simply be the monitor is failing.

Check the setup options. Some monitors have an "auto" mode which is default, but you can often select the input being used.

I did try that Setup thingy and changed it to Manual and then manually changed it to Digital but it simply loses that signal and then tries Analog again. It all makes sense, but why would it lose signal in the first place, and can it be fixed?

Then as it's occurring on two different PC's, I'd suspect a hardware fault in the monitor.

Yeah it certainly has to do with the monitor itself, but can it be fixed?
