Most current nvidia gpu's only come with 1x hdmi and 3x DisplayPorts. I think there are a few rtx3080's that have dual hdmi.
If you need to use your hdmi for your Rift cv1 then you will need a DP capable monitor. Pretty well most gaming monitors are DP these days, or like mine, do both. I'm not sure but you may be able to get a DP/hdmi and/ore DP/DVI adapter but I'm not sure how well these work. Good luck mate.
