The Intel 530 graphics chip on the 9550 can handle higher resolutions. Did you try the Intel HD Graphics Control Panel? Right-click an empty area of the desktop and select "Graphics Properties" > "Display" and see if you can change the resolution on your external display.
HDMI 1.4 can handle higher resolutions but at a lower refresh rate.
I played with the NVIDIA settings but it appears that it will only work on a program level basis and not for all programs. I assigned the NVIDIA card for a few programs, but for some it was ignored and still used the Intel chip.
Please confirm if the external display support 1920*1080. Open Nvidia control panel and change the resolution on the displays. Update all the drivers including Intel Thunderbolt3 Firmware Update and controller driver. Check if issue persists while connecting HDMI-HDMI cable.
