Unable to set resolution to 1680 x 1050 in Mac OS 9.2.2

[Alex]

Hello

I don't come here too often but I am grateful for the forum and am hoping someone can help.

So I have a PowerMac Quicksilver 733MHz attached to a 20" Cinema Display https://everymac.com/monitors/apple/studio_cinema/specs/apple_cinema_display_20.html. The display's native resolution is 1680x1050.

The GPU card is a GeForce 2 MX.

The machine can boot into Mac OS 9.2.2 or Mac OS X 10.3.

Mac OS X automatically boots into a 1680 x 1050 resolution but Mac OS 9 can't do the same. As a work around I installed SwitchRes 2.5.3 which allowed for higher resolutions but I can't get 1680x1050.

So this is why I came here today?

Is there a solution?

I might be mistaken but before having replaced the old noisy drive with a new quite HD and installed just Mac OS 9, I think I use to get native resolution in 9 but now I am not certain.

RESOLVED:

This must be installed first. I had taken note of this years ago and during the transition to the new drive it was missed.

Please find NVIDIA Drive Update 3.0v1.1.smi.bin attached, this allows the 20inch Cinema Display to work with a GeForce card at 1680x1050 resolution.

Just in case, you can always find it here. I just put it on archive.org.
