Issues with GeForce 4MX - iMac G4 - M6498 (EMC 1956)

Hello all! First post :) new owner of amazing lamp - iMac G4 - 17" LCD monitor with GeForce 4MX. Removed OSX (everything was working perfectly) - because I wanted to install 9.2.2. Managed to install OS9.2.2. Live with no issues however it seems NVIDIA acceleration is not working. I so have millions of colors but I can see for example when moving windows around on desktop its quite slow. To my untrained eye it seems like nvidia drivers are not getting used, but some general video drivers - however they are in extensions folder (nvidia drivers 3.5.2) and under Systems Profiles->Extensions I can see they are enabled (enabled = yes). When I try to start a game like Day of the Tentacle I got the message "Sorry, but Day of the Tentacle requires at least one 13" or larger monitor that is capable of switching to 256 colors"

I have followed few guides here on forum how to remove unused extensions (like ATI and the rest), however its still the same.

Some guidance is appreciated! Thank you! :)

I don't have any helpful words, I just took the opportunity to move your post into the Video cards section.

Welcome to Mac OS 9 Lives, btw! :)

This may seem overly simplistic / redundant...
but try manually changing your monitor settings to 256 colors?

hi aBc! how do you mean manually? under monitor setting I have only one option = millions :)
I think the problem is that NVIDIA drivers are not used even if they are in Extensions folder. I have removed them completely , restarted machine and nothing changed - so with them or without them its the same behavior.

Do you know how to "force" those nvidia drivers being used?

Sorry, the above unclear in original post. And I'm unaware of this problem before.
I would likely nuke the entire OS install and begin over again.

And you’ve not stated if it’s an 800 MHz?

If it’s an 800 MHz - maybe try this download:

OR for OS 9 only… the Universal Install (again?)
