Monitor on usb-c automatically reduced resolution

My current setup is using an HP Omen laptop (full specs below) which has a USB-C port and an HDMI port. For years I have been running two monitors on 2560x1440 resolution by plugging one monitor straight into the HDMI port and the other using a USB-HDMI adapter. The laptop fell to the floor recently and since the fall the USB socket has started playing up. I'd move the USB-c cable around to get the monitor working. Once working if you don't move the cable everything works fine at high resolution. But if the cable moves slightly you either lose the monitor fully (saying no HDMI signal received)
