S240HL says no Signal but computer can tell it's there

Hi all, 

I've turned my PC on for the first time today and randomly my second monitor has stopped working. I've tried updating the Adaptors and even uninstalling/reinstalling them. I've tested a different HDMI cable and still the same thing happens. It's weird because when I turn the monitor on, a noise, like something has connected sounds, and then the disconnect noise goes off. I can see it's connected, as shown in Img 1. It's also in Display Monitors as Generic Non-pnp Monitor in the device manager, as seen in Img 2. 

I'm a bit confused as to what else I can do. I've had this Monitor since 2015, so I suspect it may have just died on me but I haven't had any flickering or stuttering building up to this day, so I also wonder if there's just a device driver issue? I've tried installing the latest ICC profile but don't know what I'm doing. 

Would any be able to help?

Hi Hexiee,

What cable are you using HDMI or VGA ?

Hi There,

thanks for getting back to me,

I'm using an HDMI. I've tried replacing it and that didn't seem to work, sadly...
