I recently upgraded from a 3090 to a 4090. It seems in one way this is a downgrade....

I run two 4k160hz panels, and a 1440p60hz panel. This ran fine on the 3090.

On the 4090, there is what I can only assume is an arbitrary limitation that limits you to two monitor outputs if you run at 4k over 120hz.

From the nVidia 4090 Full specs:

4 - Multi Monitor:
4 independent displays at 4K 120Hz using DP or HDMI 2 independent displays at 4K 240Hz or 8K 60Hz with DSC using DP or HDMI Other display configurations may be possible based on available bandwidth
The same limitation is not listed on the 3090 specs, that just says 4 outputs.

This also means I can't use my Index without physically disconnecting one of my two remaining monitors.

First world problems I know, but I feel like this is an arbitrary driver lock to try to make me buy a Quadro.

Anyone know of any hacked drivers etc that bypass the limit, similar to the nVenc simultaneous encode limit hack?
