Question My monitor suddenly stopped working ?

- AOC CQ27G2U
So today in the morning when I first started my computer it went into windows update straight away, after few restarts my main monitor did not post. So I booted PC to Bios and it posted. Was happy that it wasn't GPU. Next thing I tried was switching from DisplayPort to HDMI cable ... still no post. After some time I realised there is really no logo appearing when I start the monitor at all.
Could it be that the monitor it self is dead or just the power cable ?
