Here's mine notice anything missing on yours?
It's not detecting your DVI connection.

Horrible, horrible, horrible X1900XT problem: no signal over DVI since driver upgrade
- Thread starter roadie

Hi, thanks for posting the image, that's really helpful. The driver doesn't detect the Digital input of my monitor at all, even with it and the VGA connection plugged in at the same time. Because of this I don't have the 'Digital Panel Properties' menu, which is obviously frustrating.
I have a feeling that I will either need to RMA the graphics card or the monitor. However, I am not sure which. Hopefully ViewSonic and ATI tech support can help me sort this out without having to resort to dealing with RMA's...

Driver profile for the monitor?Is it standard monitor or is it specified by manu and model No?
If its not detecting DVI port on monitor properly that is really your only chance i believe ( rma'ing monitor)
Forn - do you have any idea what DDC is on your X1900 - I only have "Secondary" here and wonders what that means

I have the ViewSonic driver for Xp x64 loaded, which is being picked up when I use VGA.
DVI works perfectly when the ATI driver isn't loaded so it's odd that it doesn't work when the driver is loaded. Mu best guess from the research I've done is that there is a conflict in the EDID that the monitor is reporting and what the graphics card is reading, as I have illustrated above. However, it's above my ability to fix it.
DDC seems to stand for "Display Data Channel":

One of my housemates might have a computer suitable to testing the monitor over DVI but I've not seen him for a week or so. When I next see him, I'll ask.

Go and get this, I use it to get the highest res settings for HDTV's.

It will give you all the DDC info from the panel.
First off, I don't think its the GF card. I'd bet that if you plugged you panel in via DVI and a second analogue monitor in next to it. Then you get to the DVI mode switch via the analogue screen, or at least get a resolution/frequency that works. It may be that when the monitor is connected with VGA it disables the DVI output.

Right, I am home now. However, no sign of the phantom flatmate. When I next see him, I'll ask to do two things. First of all to try my monitor out over DVI if his computer can output it, and secondly to use his monitor with mine to see if I can get some DVI mode goodness.
I have received another reply from ATI. Here's what they have to say:
This is what MonInfo reports:
Thanks everyone,

Thoughts? I am not totally sure it is the card personally and will try all available avenues to fix it without having to RMA it, which would be a pain.

Is there anything I need to act on regarding this?
Thanks everyone,

Back it up a bit. Try the moninfo when the DVI is working i.e safe mode. The above is a normal report from the VGA, nothing special. Maybe you need to select the secondary output, there is a drop down select when two or more are available.

Unfortunately the monitor doesn't seem to be detected in safe mode, here's the moninfo read out:fornowagain said:
What does this mean? I assume that it points to my monitor definitely being the source of the problem?
Thanks,

Hold on. Did you disconnect the VGA? One DVI connection in safe mode, yes?
Get back to that point and run moninfo. If you did already you have a monitor problem.

This is the one from the HDMI on the HTPC I'm typing at, so you can see what a digital repot looks like.
You need to try your monitor on another PC/DVI to see if the DVI DDC is missing. And try another monitor on your DVI to check if the DDC is not getting through. Either way no drivers going to work unless its getting the VESA details. I'd try a forced resolution from powerstrip.

Right, just got off a call with ViewSonic support. The chap I spoke to thinks it is a problem with the graphics card. He suggested the following:
- Obviously try the monitor on another computer, which I'll do ASAP.
- Reduce DVI blanking, which may be the "alternate DVI mode" thing suggested previously. I can't do this at the moment but will try to when stealing my flatmates monitor.
- Try different DVI cable

If you get bored and want to try something download powerstrip.

Its a very useful program for setting and forcing resolutions that drivers don't want to display. Apart from that I can't suggest much else from here, you need the cross checks. Keep us posted, I'm curious now, good luck.

Right, I managed to get hold of my flatmate tonight. Unfortunately his PC doesn't do DVI so I've been unable to test my monitor. I did however attach his monitor to my computer so I could run multi monitor to see if there were any difference in what I was able to manipulate in the CCC with my monitor attached over DVI. No dice here too.
I have played around a bit in Powerstrip and one have identified a couple of things that may help me if other people can try them out too. Within the "monitor information" page, at the bottom right there is a drop down menu giving options from where to read the monitor data.
I am unable to get information from the "read information direct from monitor" option and it gives me an error message saying "DDC communication with the monitor failed or is not supported". I assume that this is because I am running in analogue mode at the moment?
Is there any way that other people can try this option over both DVI and VGA and let me know the results? I think your feedback would be really helpful in understanding my problem better.
I also have tried the "Update EDID" option. I have the registered version of Powerstrip so I am able to do so. However, when I do this, I get the error message "A valied EDID was not detected on the selected monitor. Do you want to scan the bus for a EDID EEPROM?" I hit yes, and get another error message "A valid EEPROM was not found".
Is there any way that anyone else will be able to try this too?
Thanks,
Oliver

Well I tried this on my machine at work, which is a Dell Optiplex GX280 with some onboard graphics (Intel(R) 82915G/GV/910GL Express Chipset Family) connected via VGA to a Dell E173FP.
That's able to read the EDID directly from the monitor just fine so it seems that EDID is able to be transmitted over VGA. Therefore, it definitely looks like my EDID has become corrupted in some way.
I am going to try and get further help over that the Powerstrip forums and also call up ViewSonic and add this information to my support ticket.

Any closer to a solution?
I have been without Internet access at home for something like 5 days so sorry for the late response.
In the end the guy at the Powerstrip forum said that the EDID data that was being generated was infact wrong. I called up Viewsonic and they sent out a replacement monitor, which worked perfectly over DVI. However, it had a dead pixel right in the middle of the screen and none of the buttons on the front worked so I called Viewsonic again and they sent out another monitor, which is fine.
I don't actually have 3 monitors now; they took the faulty ones away.
