Hello,

I have a 5090 which has 3x DP 2.1 ports.

I have 3 monitors that have HDMI 2.1 ports and would like to connect them to the DP 2.1 ports of the 5090. I’m looking for the correct adapter.

I need to be driving them at 3840×2160@144Hz space waves in 10bit color + HDR each.

So far, the only adapter with DP 2.1 to HDMI 2.1 I have found is this one: CSV-7330 I’m not sure if it is suiteable, as it is DP to 3x HDMI. But I guess using each dedicated DP port (per monitor) would make more sense. So using 3 adapters.

My monitors do not work well with DSC, so I need a solution that doesn’t use Display Stream Compression.

What I’ve tried is using the “old” adapter CAC-1080 – this actually works at the desired 144Hz. But sadly it doesn’t support VRR (G-Sync in case of my monitors).

Is the CSV-7330 suitable for my scenario? And does it support G-Sync (VRR)? Or is there another adapter you can recommend.

Thanks in advance!

Using three separate DP 2.1 to HDMI 2.1 adapters sounds like the more reliable approach. The CSV-7330 might limit bandwidth per port—so individual adapters like the CAC-1587 could be a better fit. Just double-check VRR support to ensure full G-Sync compatibility.

You don’t need to populate all three HDMI ports. Using one, two, or three of them should work.
