I got a K55n-HA8123K laptop for christmas a couple years back. I updated it to Windows 10 a couple months ago and it worked fine. I just had too much junk, so I factory reset. This took me back to Windows 8, so I updated to Windows 10 again. Ever since I used the update tool, the laptop restarted and has had no signal to the tv I'm using, via HDMI. My screen is cracked so I must use a monitor. It isnt a monitor issue because I have the same problem with other monitors. How can I fix this? The laptop is practically unusable. Thanks in advance.
