AW2725DF, will not stay on, black patch in the top left corner

Question

hi guys I have the above monitor

and since yesterday the display will not stay on but the RGB remains on as does the power LED.

ive noticed that when I can get it to display an image there is a black patch in the top left corner that wasn't there the day before.

and now its there the display will only stay on for a few seconds with a perfect image apart from the area with the patch. I can't see no physical damage to the display in any form, and it's just gone over a year old.

I know it has 3 years warranty

but has anyone else had this happen without any physical damage to the display ??

p.s before anyone says it this monitor lives on my computer desk there are no children here and its always been used as a 4K monitor only.

thanks for any help.

@DELL-ChrisM2​  Hi Chris thanks for the reply I have tried all the steps mentioned and I still get the same issue. im literally banging my head against a wall with dell support as its not real time. im starting to think the monitor has an issue and it needs to be replaced or repaired under warranty. to say I am disappointed is an under statement all my machines are dell minus my MacBook Pro but then again apple isn't much quicker on solving things. is there anything else I can try ??? ive been asked to send a picture of the power cable connector end and then a picture of the connecting socket on the monitor ive tried multiple computers including my MacBook Pro I get a perfect image for about 10 seconds and the display then goes blank. im thinking because its an Oled monitor its detecting a short and shutting it down despite the image being great other than a dark patch in the top left corner. its just a shame its gone like this as the warranty is just over a year old I know I get 3 years on this but that's not the point it should last longer. anyway rant over lol. thanks Jason

@iNeedHelpWithMYMONITOR​  sadly mine was replaced under warranty. As it was deemed it was a panel issue. best bet is to contact dell as these monitors have a 3 year warranty on them.
