45GX950A + 4090 — what to expect?

Hi All,

So I bought this super sick new monitor which I’m sure a good amount of you on the sub are aware about.

My question is since it comes with DP 2.1 and only the 50 series supports 2.1, what can I expect in terms of what I’ll be able to push out from my existing 4090 ports. Will I be able to support the full 5k2k 165 in hdr with dsc enabled or something?

I plan on getting a 5090 only if I can snag one for a reasonable price (whatever that even means now) but that might take a while so I expect to have my 4090 for a bit honestly. And then I guess my second question is would it be better to use my hdmi 2.1 or dp 1.4 when I do get the monitor.

Just wondering since yall problem know more about the specifics/expectations I should have than me.
