Is a vertical line on a new LCD monitor acceptable

I just purchased a Dell UP3216Q monitor directly from Dell. This is a 32" 4K 3280x2160 edge-lit LED monitor.

Dell's product page: https://www.dell.com/en-us/work/shop/dell-ultrasharp-32-ultra-hd-4k-monitor-with-premiercolor-up3216q/apd/210-afln/monitors-monitor-accessories

There is a very thin red line running vertically down the screen just about 13 cm from the left edge of the screen. It also appears during the Dell monitor diagnostic, so it clearly is coming from the monitor itself and not any application or Windows.

Should I consider this normal or a problem? Might it get worse over time? I am looking for your insight to determine whether to call Dell tech support and possibly look to exchange the monitor.

Thanks, Pete

NO.  Not normal. Contact Dell Support. They may have a true fix in the form of a driver for you. But most likely it needs to be returned and replaced

There was a time where dead/stuck pixels were acceptable (a certain percentage, usually just a handful on a screen). But with the current technology, the bigger brands don't even have those anymore.
In your case, it's clearly a cable or other electronic defect that's not our fault. And if you count the pixels, it's WAY more than a handful (over 2 thousand to be exact). Definitely not acceptable, and a full replacement is warranted (request replacement under DOA rule).

John and Kimputer,

Thank you! You equipped me with the background I needed.

It went very well. I called Dell tech support. Since I had already confirmed that the line appeared during the Dell diagnostic, the representative immediately said that they would need to replace the monitor. The most-difficult part was that he needed me to photograph the line and the serial number, and email that to him. Photographing a one-pixel-wide line with a phone camera was a challenge!

The advance replacement is all set. They send the new monitor, when I get it I ship the defective monitor back with a prepaid label.

I learned a couple things:

I paid about $100 more to buy the monitor directly from Dell compared to what Amazon sells it for. I think it was worth it since the swap process may be easier given that I bought it from Dell. I used Amazon's price/shipping to get a better deal from Dell.

From now on when I get a new monitor I will use the diagnostic test to look for display problems right away!

Thanks again for advising me how to proceed.
