I have just started setting up my first Raspberry Pi (3). It was easy to set up initially, but after setting up remote access with VNC, I disconnected the HDMI monitor (actually my TV). Now when I remote into my home laptop using teamviewer and then remote from there into my pi - this also happens if I just remote directly from my home laptop to the pi - (Still having trouble remoting from anywhere but on the same wifi network) the display is wrong. Everything is fuzzy, but the worst part is that I not only cannot see the entire screen at once but in new windows I can't see the top of them, so many times I have to guess what they say. Is there some setting I need to change?
