I've got an LX motherboard(this) and am trying to get an Asus 6800 GeForce to work on it.
After doing the normal "change display type" before taking out the old card, I put the Asus in and restart. The card's BIOS shows up fine, and it boots into Windows98FE fine.

Once in Windows, I've tried a couple things to get the card working:
1. I've run the newest Nvidia reference drivers executable(23.11 I believe) and installed the driver. After rebooting, the card still doesn't show up in Windows. In Display Settings>Advanced>Adapter, it shows up as Nvidia Geforce DDR, but in the part where you change the res and color depth, it says "Unknown Monitor on Unknown Device", and I'm limited to 256/640x480. It showed "Plug and Play monitor on Standard VGA" before I installed the Nvidia drivers. I then uninstalled the drivers and cleared everything nvidia related from the harddrive and registry.

2. I've gotten an older version of the drivers that come in a zip, and I do the old fashioned driver install, pointing it to the unzipped directory. Same results as above.

3. Tried forcing the card to AGP 1x via a registry hack. Nothing doing.

Sorry for babbling, I'm almost done.
I'm wondering if this is a motherboard issue(those silly AGP voltage issues that plagued the ALI chipsets, surely aren't also in the LX chipsets?), a driver issue, or perhaps something that could be fixed with a registry hack/change? It seems to be seeing the card ok as the one screen shows Nvidia Geforce DDR, however the other shows Unknown Device and the resolution and color depth can't be changed, which then limits everything within Windows.

Any ideas? I'd REALLY appreciate some help with this one. I told my aunt "5 minutes, tops" before I went over there to install it. 3 hours later.....
 
Try flashing the mobo BIOS. That may help to alleviate some problems. After you flash your BIOS load the "Fail Safe Defaults" or "BIOS defaults". That may eliminate compatability problems with the card too. I'm sure WindowsFE could use some updating as well. After you get all of the necessary updates, try setting the card back to Standard Display Adapter, restarting and running the Geforce 23.11s from Nvidia's website. It shouldn't make a difference whether or not you use the auto installer so just go with what's easier.
 
I had actually flashed her BIOS with the newest one a few weeks ago, in preparation for a new CPU which ended up not being compatible anyways.

I didn't try changing the monitor type, once the drivers were installed though. I'll give that a try, maybe once it finds one it'll find the other? Who knows!

Thanks fellas.
 
When Winblows can't recognize the monitor type it'll default to 256x640x480 as a failsafe to prevent damage to the monitor from a refresh that's too high. Once you get the right monitor drivers loaded you should see more options for resolution and refresh rate.

Once that's accomplished you can give reinstalling the latest Nvidia driver another try. You should be getting the GeForce DDR tabs in Advanced display properties if the drivers are correctly installed.
 
I don't know where you got the idea that this problem was limited to ALI chipsets. As I remember, a boatload of LX motherboards could not run the GeForce properly when it first came out. A limited few could fix the problem with a BIOS update, but most users were stuck until they upgraded to a new motherboard. If I remember right, QDI has stated that none of their LX motherboards officially support the GeForce series. Those that have reported success with a QDI LX were lucky.

Anyway, there may mulitple, old display settings in your registry that's causing the problem. Try this. Run regedit and follow the path:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display

Delete all the sub-directories (ie. 0000, 0001, 0002, etc.), close regedit, and then run the driver installer.
 
I agree with the monitor......Getting the Vid card's drivers installed correctly is
the 1st step. But many ignore the monitor inf's and if you don't get those right,
you're stuck at lower resolutions...........

<< it says "Unknown Monitor on Unknown Device", >>


If the proper monitor inf files are not installed, you will not be able to select the resolution and refresh rate. this is true of any video card on any mobo.
 
Got some good ideas from this thread! 🙂
Looks like monitor drivers should fix my problem up nicely, I've got a whole list of stuff to try now. And if none of that works, she's just going to have to upgrade. LOL
