Intel Arc 770 doesnot have 2440p resolution when connected to DP port.

[PCGoon]

I have an Intel-branded Arc 770 GPU running with 13th Gen Intel i7 with Windows 11. I have two Dell monitors that do support 2560×1440p resolution. The setup was working fine until recently. Recently, there is no more 1560x1440 available on DP port anymore. All three DP ports are only running at 1080p. HDMI is still working at 1560x1440p. There are many complaints about this but I don't see any fixes. I am running the latest drivers. My Dell monitor models are : S2722DGM (27" inch).
