Also, for my Raspberry Pi 4, I plugged mine into a widescreen monitor and there was a huge boarder of unused pixels, after I had used sudo rpi-update without knowing what it was for (idiot).
So, what I did was, first followed the first step and all i did was remove the # from #disable_overscan=1 in the file /boot/config.txt and then rebooted.
That did the ...
Get a fresh install of a known good OS for your hardware.
Test with that, if issue persists, check cabling. Check on different monitor as well to rule out your display.
Also check that the solder points on the video component are sound... Sometimes it will look like it's soldered, but the old solder can lose its bind to the board, lot of times due to ...
If it's definitely not a cable issue, you can either install a remote desktop (if you are using ssh from another computer anyways) sudo apt-get remove xrdpand then use for example the standard windows remote desktop or use X11 forwarding how to use remote connections (stackexchange)
Update for future generations of newbie tinkerers: I ended up going back to stock Raspbian and starting over. Everything worked great out of the box. I managed to get touch working merely by enabling SPI and adding dtoverlay=ads7846 (and its usual arguments) at the bottom of config.txt. This lets me keep using the screen layout editor too. However I have ...
If your TV supports CEC you can do it.
CEC, or Consumer Electronics Control, is a feature of HDMI which
allows controlling devices connected through HDMI using a remote
Install the cec-utils package (cec-client is part of this package)
sudo apt install cec-utils
Now that cec-utils is installed, let's scan the CEC bus for available devices:
You have provided no meaningful information which would allow anyone to provide a definitive answer (and no actual evidence of any problem).
The most likely scenario is that the Pi has booted, but you have asked it to do the impossible i.e. boot to Desktop when there is no default Desktop (an examination of the boot logs would probably confirm this). See ...
This result works for me:

I've fixed it, an 'apt-get purge pulseaudio' followed by a reboot seems to have restored order to the universe, youtube plays in chromium and VLC works great.
How I managed to get pulseaudio installed is unknown, it may have snuck in while I was playing around trying to get ...
There is an option hdmi_force_hotplug=1 in config.txt, although AFAIK the Pi4 will always use HDMI unless overridden, but it will do no harm.
You should also set a resolutions in raspi-config otherwise the Pi will use an impossibly small screen.
On my Pi4 this sets
#DVI DMT (35) RGB full 5:4, 1280x1024 @ 60.00Hz
and this can be ...
