No DVI with anything other than 100.65

[bOingball]

Hi All,

I have a GeForce 8800 GTX 748Mb installed on a Windows Vista Ultimate Box

It has dual DVI on it, and is wired to my 26" LCDtv via DVI.

with the 100.65, DVI is enabled and works great with my card and monitor.

Installing 101.41 DVI turns itself off and can't be re-enabled (No Signal on the DVI port, the only way I can get a display is to use the DVI + VGA adapter and plug it to the VGA port of my monitor)

The same problem happens with the 101.70 drivers.

Has anyone else had this problem? it's annoying as DVI works on my Linux partition / and Windows XP partition.

If anyone knows of a fix for this I would be greatful.

(and I don't really want to use VGA as it's fussy, and my Xbox 360 is used over VGA ;) )

DVI output works fine in Vista with the 101.70 drivers here.

I'll have a try again with DVI, if I boot up with the DVI cable in with anything other than the 100.65 drivers I'll see the windows bootup loading 'green' bar.

and then I'll get no signal after it gets to the Vista Logo Startup screen.

It shouldn't matter which DVI port I use? - I've tried both with little success on either at the moment.

works fine here with both my 22 inch gateway and 37 inch westi

both ports should work the same.

only thing that comes into mind is that you might have set refresh rate that your display doesn't support, and once driver kicks in and sets the refresh rate, display doesn't support it/can't handle it and screen goes black

captnkill, had some issues with refresh rate also, he mentioned that certain refresh rates were missing in 101.41 ini files.

Cheers for the reply, I've just rolled back to 100.65 and it works fine again on DVI.

When I upgrade the drivers I lose it as soon as the new drivers kick-in, so if I do a windows update now 101.70 will install, and whilst installing I'll get nothing half way through the driver install screen (unless I plug in the VGA cable back in) (which then will display my image)

it's weird as well as the 101.70 can detect my DVI screen but won't even enable it if I use it as a secondary monitor, just ignores what I tell it and disables it without even trying to work.

I tried 101.70 in low rez mode 640 x 480, but I can tell you it's not even trying to output anything over DVI anymore.

I've reported it to Nvidia as a bug as theres nothing really much more I can try. :( which is a shame as I'm stuck with 100.65 until I driver will support DVI on mysetup... (weird as I've not had a problem like this before)

I wonder if anyone else has this same issue, I'm using a DVI- Digital only lead to my LCDTv.

well you do have LCDTV, instead of normal LCD, there is a difference

do you know what is the max res, refresh rate for your monitor?

[bOingball]

Well the nvidia drivers limit the DVI Refresh rate to 60Hz

I have 3 options 58 / 59 / 60 in my display adapter settings now.

Windows when doing a driver update does 60Hz as well (well should...)

it's set to 1280 x 768 at the moment in the 100.65 drivers (If I install them it kicks in to this set rez)

Windows XP does the same.

I used to run it at 1600 x 1000 but theres no advanced timing panel in Vista just yet to get this rez :)

I don't have another DVI monitor about to test it either :(.

I've just looked at the missing Refresh rates with the newer drivers and they do have a lot of the higher refresh rates missing from them but they all have at least 60Hz there :)

I'm a software developer by trade so I can sorta debug whats going on with the drivers, it looks like it checks for DVI but detects nothing and skips the DVI init in the newer drivers. It could be that the newer drivers don't like my monitor not sending out an EDID (Rarly LCDTv's do)

Looking at the release notes nvidia updated the DVI code to give LCDTv's better support with 1360 x 768 as supported as well if theres no EDID.

I had a 6800GT 256Mb before this but it died on me a few weeks ago hence the 8800 GTX replacement.

I doubt theres many setups like mine to verify the problem I'm getting though.

My problem wasnt quite the same but maybe this can help somehow. When I updated to 101.70 Vista for some reason made the 2nd card (monitor 3 if I was running an extended desktop) the primary monitor source. I had to re-assign the correct DVI port to Mon1 in Display Properties before installing the drivers for it to work on the correct DVI port. Odd, and this is the only time I've had that issue thru 3 driver updates so far.

Nice - I wonder if I stick in a PCI Geforce FX5200, mod the inf and try it's DVI to work and then see if it would work but thats a lot of hassle to get 101.x to work.

I've tried having a VGA and DVI cable pluged in and it sees 2 monitors, but I can't enable the DVI one, Click Extend to this Desktop (I say Yes) it comes up with do you want to keep this setting, I click Yes and it's still disabled.

I'm hoping the bug report might get somewhere
