My Acer KG251QF Monitor won't connect with the HDMI cable after switching my Xbox off and on?

This happened about 4 days ago. I switched my Xbox off to go to sleep, next morning when switching back on - no display.
I've only had the item 5 months. Any suggestions on what to do please? I've tried using a different HDMI cable to see if that makes a difference.
Thanks in advance.
