Windows 10: External monitor randomly stopped working

I have a Windows 10 laptop and an external monitor. The monitor was working perfectly for a few weeks, until one day I switched on the laptop to find that the monitor was no longer working. Going to 'Display Settings' only showed one monitor, and pressing 'Detect' said 'Didn't detect another display'.

After updating all drivers, then purchasing new leads and adapters for the monitor, I still couldn't get it to work. Then I stumbled upon the 'Hardware and devices' troubleshooter which, after restarting my computer, made it work.

Less than a week later, I just restarted my machine and suddenly it's not working again. This time, the troubleshooter isn't fixing it. Every time, it just says to restart my computer to finish applying updates/drivers but restarting doesn't help.

Anyone have ideas how I can fix this?

Cheers

Hi there,

I used to have the same problem on my previous machine. It could just be as simple as changing your connecting cables, or backlight of your computer could be the culprit, or both (which was in my case).

Best of luck

Compatibility mode didn't work but just installing the new driver did.

 

Installing the new Intel graphics driver worked (by downloading from manufacturer website and running setup).
