Help! I'm using an HP laptop 2000 219dx, running Win 10 plus update.  Up until about 2 months ago, when I plugged in my HP display, everything worked just fine.  After that, when I plugged the display into the VGA port, my notebook display flickered, and then only showed the far left column of apps on my desktop.  The extra monitor itself showed a "no signal" icon that moved around the screen.


Next I plugged in a new tv to see what would happen, and it also showed a "no signal" icon, but I was able to change the input to "pc" with the remote.


I've spent days on the net trying to find solutions from AMD, HP and other tech sites, but to no avail. I uninstalled and reinstalled drivers and software for HP displays and AMD products, and I still am not able to get either device to work.


There was one instance when I unplugged the HP monitor - to get the regular desktop screen back - and the "printers and devices" area showed the correct HP monitor.  I right clicked on the icon and it showed me its properties, but when I tried to troubleshoot it, the icon went away.


I'm at my wits end trying to get either device to work off this laptop.  If anyone has any suggestions for how to fix this, I'll be forever grateful!


Thank you!

The best way to connect an external display to a laptop is when the laptop is off and then boot the laptop with the display connected and turned on.


If that doesn't work for you try WINDOWS+P to bring up the display options and see if you can set the displays that way.


You might want to see if there is a BIOS update for your machine.
