ASUS monitor several years old.

Work laptop software updated yesterday and today my monitor displays a no HDMI signal message.

I've plugged it into my PS4 and the screen changes to a black screen suggesting activity but then nothing subsequent appears onscreen.

I've tried factory reset to no avail.

Any tips?

I have had the same happen a couple of times with my work laptop and external monitor.

I phoned our IT helpdesk and they explained that it can happen sometimes when they update their policies.

I had to go and sit outside one of our supermarkets, pick up the corporate wifi and the IT guys updated the policies and everything was okay after that.

It's weird as the PS4 gets something out of the monitor, albeit a sort of blank dark screen whereas laptop gets no HDMI signal.

It's about 4 years old - is that normal? Appreciate they're not built to last forever.

What Drac said.

HDMI is a 'secure' connection, it's not simply video in ➡ video out. If the cable's on the wonk and it can't negotiate communication then Computer Says No.
