You created a phase 2 definition for a vpn tunnel. in the local network dropdown list, you selected network and type 0.0.0.0. what did this accomplish?

Ihave a singular monitor that is a tv for my computer. recently, i took apart my computer and put it back together. when i put in the hdmi cord and booted the computer to see if it worked, the computer turned on fine but the screen was blue with "hdmi no signal." i've tried everything that doesn't require buying spare parts, any answer is appreciated!
