Having a slight problem with my old lg110b. No matter what i try, the monitor will not receive a signal on the dvi connection. Analog is fine and dandy, but try dvi and the monitor just goes into standby.
Ive connected the vga and dvi up, then put my 7800gt onto clone but the dvi doesn't pick up a signal like the vga does.
Any ideas on all this?
Cheers
FIRST - make sure your resolution is set to that of your monitor and refresh rate is correct for it (probably 60Hz).
If it's not that - I've just spent a day or so researching this and it appears many many people have the same or similar problems with DVI ports, using both nVidia & ATI cards, and with many different monitors.
Not only that, but this has been going on since the launch of dvi some years ago, and the card & monitor manufacturers have been notably silent about it, each blaming the other when frustrated users actually try and contact them. It is frankly a disgraceful situation that the industry as a whole should be ashamed of, and it stems from the origins of the dvi format and a notable lack of standards, approvals and checks. The problem also continues today with issues involving HDTV's into pc dvi ports.
The exact cause of your problem may be difficult to pin down, but is most likely that your monitor is reporting an incorrect EDID when the system starts causing the computer to believe it is either a completely different monitor, an analog monitor or that it is of an incorrect native resolution.
The best dvi troubleshooting link I have found is here:

If you search the web you'll find forum after forum of frustrated users offering each other advice in the absence of acknowledgement by the manufacturers. Solutions vary from simply simply changing your monitor properties in XP, plugging your monitor in after XP has already booted, rolling back graphics drivers, low level editing of the EDID data, underclocking your card or changing its blanking interval. In short there may be an incredibly simple fix for you or it may be impossible requiring you to exchange it for a model that behaves better.
Sorry to be somewhat vague - I'm still trying to understand it myself, and if I offered definitive advice I'd be as guilty as most seem to be of confusing the issues further.
FYI I have a 7800GT also, and a Philips monitor which was identified as digital on day 1 but thereafter, has been identified as analog, and runs in analog mode - going blank if I try and switch it back to digital with the on screen menu.
