[SOLVED] Help! Monitor stuck at 4k@28HZ

[LackingLiberty]

So for some background info, my monitor is the LG 27ul600 which obviously isn't the issue and I'm using the cable that came from the box which supports 4k@60HZ so it's clearly an issue with my laptop. I've been using my laptops HDMI port to connect the two but I now suspect it's limited to 1.4 hence why it doesn't support 2.0 which is what's needed for 60HZ. It also doesn't appear like HDR is showing up but I don't care about that. My laptop uses Intel HD graphics 620 and has no dedicated GPU but I know the 620 supports 4096 x 3280 @ 60HZ so it must be the port and/or the motherboard. Is there ANY way I can get around this without scrapping my whole laptop? Any type of cable/chip/conversion that can solve this for 4k@60HZ. Any help would be appreciated, thanks.

Laptop model: HP Pavilion x360 m3 convertible with an i5-7200U CPU/ Intel HD graphics 620.
