Hi. Sorry for delayed response.
Finally I figured out the issue reason. The subject laptop (Lenovo G15 V3 IAP(82tt)) has i7-1255U. For some weird reason HDMI output cannot render @ 3440x1440, but goes well with 4K. I've attached laptop's USB-C output to monitor's DP input using USB-C->DP cable and all caught up just perfect. So the root cause is the i7-1255U iGfx.
