Hi,

I've got a PC with an rtx4090. It should in theory be able to support 4 monitors but currently I can't make that happen, either through the regular windows settings or DF. When I try to enable the 4th monitor it always just does nothing and then asks to revert or continue. the 4th monitor never changes, always stays black.

I can make any combination of 3 monitors work just fine, so each screen and its connection works indepedently, but can't have 4 in total.

Any idea what is going wrong here?

Thanks
