I've been running a dual monitor set up for a long time, with an external samsung 20" hooked up to my laptop. On Friday, I had to unhook my laptop for a presentation and came back and tried to connect it back up, but the monitor says "check signal cable DIGITAL".

Its been connected to a normal VGA15 pin cable for ages and working fine, and this is the first time its done it.

Have tried:

1. Restarting computer
2. Swapping signal cable
3. Checked signal cable was working by connecting another monitor (it works)

Any ideas on what else I can do?

Monitor is less than 6 months old.

Thanks!

If the screen is saying Check Digital cable and youre using a D-Sub VGA cable, then it should be looking for an analog signal, not digital (DVI) - can you go through the monitors settings and get it to use Analog only ?

XP.

Can't change anything - it won't let me go into the settings. I didn't change any settings prior to removing, so don't know why it should change on its own?

I may be out of my depth here (probably) but I have a similar set-up.

Sometimes when I dock my laptop again I need to use the laptops display output toggle settings, the one you use when setting up for example a power point projector or similar, to get both going again (FN + F5 on my Toshiba) ?

Thanks though.

And if you right-click and show the display settings, can you use the identify Monitor option so it searches for monitors?

Yeah it identifies the monitor and knows its there, but i get no picture and the generic "check signal cable"...

I've had the same issue crop up with my lappy and external monitor, the only way ive found to solve it is to reboot the lappy with the external monitor pluged into the lappy and then go to display propertys n click the 'extend desktop onto this display' option

There's no a button or OSD option on the monitor to change the input mode from DVI to VGA is there? It (the monitor) might have got confused and be stuck on thinking it's supposed to be listening to DVI.
