Monitor resolution 5120x1440 on Intel Iris Plus Graphics 655 (NUC8i5BEK)?

[Apollo81]

Hi, my Intel NUC 8i5BEK only create a max resolution of 3840 x 2160 on my new Samsung C49RG94SSU.

The Operating Systems is Win 10 with the latests Updates.

Running Graphics Command Center will not allow 5120 x 1440 as a Customer entry.

Any Intel Driver i found (27.20.100.9025 / 27.20.100.8935 / 27.20.100.7985 / 27.20.100.7262) also only created a max resolution of 3840 x 2160.

On the other site, my older Intel NUC7PJYH create a max resolution of 5120 x 1440 on Ubuntu 20.04.
