Vertical line on monitor sometimes appear and dissappear, should i warrant it?

[Giant_Hunger]

Hi there, i just bought this p2715q 4k monitor back in april and recently this week there has been vertical line appear and dissappear sometimes.
I know the problem isn't my gpu because i use a quad monitor setup hook up to my rx 5700 xt and all of them doesn't have any vertical lines except for this one.
As of writing this right now the vertical line has disappear. It has appeared for quite sometime now.
What should i do?
Should i change my display port cable? Or should i warrant my monitor? And will they accept my warranty if theres no line when i bring it to them?
Here is the verticle line( sorry for the bad camera quality)

I'd send some of the photos to the brand, explaining your issue, providing proof that this is your monitor and you're having the issue.

 

Maybe the line is not enough to engage repair or replacement, but a written word from the customer service might be... a starting point.

Try a new cable, maybe tapping the screen to see if it's a connection or something loose.

 

But at least you have pics to share with them as well.  I'd start the process.
