7700XT will support 2 monitörs like one of 144 hertz and other one is 240 hertz?

Hi everyone, I decided to buy a 7700XT this week but there is one thing i want to ask. I have two monitör, one is 144hz and the other one 240hz. Will i be able to run both of them at their max hz? One will be plugged with the HDMI and other one with DVI.

The RX 7700XT does not support DVI natively. Are you using an adapter? Any assurances for resolution and refresh rate will need to come from the adapter manufacturer.

That should be a-okay provided the hdmi cable is up to the task. The ports on the card itself will be more than enough.

Edit: I should note I haven't actively used Windows since XP, so I don't know how recent Windows display servers work. If there is a reason why this wouldn't work on the software side, someone please chime in and correct me.

I suspect DVI may not have enough bandwidth for either of those refresh rates depending on resolution. I'd prioritize using Displayport if you can. For HDMI make sure you're using a cable that's at least up to the spec of your monitor's HDMI controller. Avoid using old HDMI 1.x cables. If you're uncertain just pick up an HDMI 2.1 cable (or better yet Displayport cables). 

I don't know about Windows, but at least under GNU / Linux you can run multi monitor setups with mismatched refreshrates and with a mixture of VRR and non-VRR display modes as long you're using Wayland rather than X11. With my RX 6700 XT I use two monitors, a 1440p 165 Hz monitor with freesync, and an old 1080p 60 Hz monitor without any VRR support. Works perfectly with Plasma Wayland.

Okay sorry i have a display port not dvi. Will 7700XT does support 240 hertz display port monitor + 144 hertz hdmi port monitor at the same time?
