No DVI with Geforce 3 Ti500 and Dell 1900FP LCD

I just got a dell 1900fp and I can't get the digital video to work. I have a Geforce 3 Ti500 (Visiontek Xtasty 6964) with the 40.72 detonator drivers on WinXP Pro. Connecting via analog works with no problems... connecting via digital results in the loss of signal after the winxp splash screen. How can I force the digital connection? DVI works in safe mode. Any suggestions?

Thanks!
 
hi,
in analog mode make sure that your video is set for the lcd native resolution 1280 x 1024 and set to 60 hz. then shutdown, move to the dvi cable and reboot. this should give you a picture. also, make sure that you have installed the monitor inf files.
most often this is because the display is set to a resolution or refresh rate outside of what the lcd can capture.
good luck.
 
I've done what you had suggested, still no go. Usenet searching came up with a number of people that had similar problems, but no solutions... :disgust:

Time to upgrade the video card?

I have the same monitor and same video card and am also having the same problem.
Still don't know any answer.
Will let you know if I work out something.
BTW, when I bought my Visiontek, I thought it would last me at least 3 years.
I really don't want to upgrage again.

 
After spending a couple hours searching various forums and usenet postings, and my on "testing", I think the problem for me is the Detonator drivers... in XP DVI works fine in safe mode. As soon as I change to the detonator driver, the LCD goes into powersave mode. This leads me to two possibilities...

1. XP is trying to force the LCD to use an unsupported resolution/frequency, and the blank screen is the result of bad synching.

I don't know how this is possible. I've set the refresh rate to 60Hz, and have use a myriad of resolutions from 800x600 to the optimal 1280x1024. In safe mode I was able to go up to 1280x1024 with 32 bit color without problems.

2. there is something broken with the hardware involved (the monitor, videocard, or the cable)

I can't see this being the problem either, since it works in safe mode.

Therefore at this point the only thing I can conclude is that the drivers are broken with DVI for me. The option to select a digital display is greyed out and I don't know how to force the drivers to use the digital display. At this point here are my choices...

- wait for someone to post a fix (who knows how long that will be)
- get a different video card (already blew a lot of money on the monitor, I'd rather not have to buy more equipment)
- get a non-NVIDIA video card (since I game a lot, that means a Radeon of some sort. Is ATI a good solution now? How about their drivers?)

Sigh...

PS: On a whim I emailed Visiontek tech support... they suggested to flash the bios on the card... of course I have to wait about 9 hours before I can get home to try it out.

 
Hi balder,

I got a reply from someone who was in the exact same boat as us.
He said he did a BIOS flash, and it fixed the problem.
I really hope flashing the BIOS would fix our problem too.
I have already email Visiontek's tech support but haven't got an answer yet, and the guy said he didn't keep the file.
Could you email me the BIOS file and instructions (if any) you got from Visiontek in case I don't get their reply today?


Thanks a lot!
