Why "No DVI signal"?
Friday, 07 November, 2008
Every time I turn on my monitor all I get is a message saying
No DVI-D input signal
and I can't see the computer on screen. Yet the computer is connected and as far as I know it's working properly.
How can I fix this?

 Since the PC is connected to the monitor, I can assume that it has two input ports.
The first is a standard VGA port (which you've connected to) and the second is a DVI port.
At some stage the monitor has been set to default to the DVI port, when turned on,. but as you don;t have anything connected to that it won;'t display anything but that message.
There will be a Menu button on the monitor and you'll need to look for the setting that defaults the input to VGA. (Of course if you have the manual that will make it a bit easier). Then each time you turn the monitor on it should be in that mode.
If your graphics card is high quality and the monitor is too, then it may be worth buying a DVI cable (or finding the one that came with the monitor). Why? Because DVI is digital and VGA is analogue and generally digital is better.

JCPosted: 16/11/2008 re: Why A point worth checking out (as I did, with a 'revision' of my monitor's On-Board 'Menu'),Yes, there is a part in the Menu where one can change the 'Input Signal' type (Analogue or Digital).
Will be OK, to play around with it, just to know 'what' is in the 'Menu', to become familiar with 'what' your monitor is capable of.
Mine even gives the correct "Refresh Rate/Hz"....that should be NOT be altered (for any reason!)...since it IS the correct setting for the monitor.
Too lazy (to look/play/tinker) with your computer as I do, well, be it on your own head, for not developing the knowledge/experience one does require, in order to do your very own 'trouble-shooting' when you DO strike a 'problem'...with your computer.
It definitely does save, on your wallet or purse, whichever you prefer, in the 'long run', as I have always stated, that, "The best computer 'technician', pf course, is your very own Self!"
It's all right, for you NOT to learn, BUT, you will be always the one 'out-of pocket/without a computer'.
Not me, just remember that. JCPosted: 14/11/2008 re: Why There's a point that everyone's probably overlooked here, and, that is....." What is Alan using for his 'Graphics set-up' "?
Is he using the the 'on-board Graphics'(of his motherboard)?
Or, is he using an 'add-in' Graphics-card?
If he is using the former (albeit, the 'on-board Graphics' set-up)...maybe it can not display the "DVI-D input signal' his montor does require.
Should this be the case, he should switch to an 'add-in' card, instead.......and turn OFF the 'on-board' Graphics, before restarting his computer.
(If he has already added such an 'add-in' Graphics-card....maybe a check is warranted...to ensure that he has not left the 'on-board' Graphics 'Enabled'?)
Why?
Because the 'on-board' (and 'add-in ) don't like working together.
If his Monitor is the newer LCD type, there is a chance that there is a 'driver' (for the monitor).....on a CD that came with the monitor.
Don't laugh, and say that there is no such thing as a 'driver' for the newer types of monitors.
I have 22" widescreen LCD monitor, and it certainly did come 'supplied'...with a 'driver' for it.
Without it, my monitor (otherwise) shows up as a "Plug-n-Play monitor". Works better with the 'driver', though, especially with the OSD Menu 'set-up'.

Switch all back On and hopefully those "logic" switches are all reset and all's well again.
Goodluck
