I have a laptop with a cracked screen, so I connect it to a tv via HDMI. It was running windows 10 and I had too much stuff installed on it so I did a factory reset. What this did is reset it to Windows 8 (or 8.1, not sure), the way my laptop came. I then updated it to windows 10. After updating, the laptop had to restart. Ever since it restarted, I've been getting a sign on my TV saying no signal. It's a problem with Windows because I get the same error if I plug it into a different monitor. How can I fix this?
