Ubuntu - How can I find the screen resolution using command line

Question

I connected my laptop to a big FullHD monitor, but I don't know what is the screen resolution of the monitor. Is there any way in Ubuntu to check the resolution from command line?

Try this command on terminal

xdpyinfo | grep dimensions
