How to change screen settings or display options from terminal (L)ubuntu 18.04

My laptop has had a mishap, a heavy impact on the keyboard :/

Something inside has been damaged and the screen is now very fuzzy and flickering. BUT, it looks perfect when connected to TV via HDMI. The only problem is the screen resolution is different so the taskbar/menu is not visible.

Is there a way to get into screen settings via the terminal? I can open the terminal via CTRL ALT T but using gnome-control-center opened up an empty panel with no config options.

As far as I can tell from the tv screen, the laptop itself is working perfectly, the display is the only problem. If we weren't in lockdown I'd have it to the repairman pronto but for now it's going to have to be a temporary solution.

Any advice gratefully received!

Try with

lxqt-config-monitor

It should open monitor settings and you can change resolution from there
