S2716DG, defective screen
Here are the weird things that I've noticed on my Dell S2716DG (rev A02) monitor (bought it mid-year 2016, built on February 29, 2016.), after running a few test image from the popular eizo and lagom monitor test:
Thin, horizontal lines across the screen, from top to bottom. This thin line doesn't appear on the very top 1.5cm of the monitor. The lines are very visible on the left and center part of the screen. This causes text to appear a little weird (I don't know how to describe this), it's like the text font is not consistent and deformed. Only the right part of the monitor looks ok.
The center-right part of the screen flickers, approx once every second. It's very obvious if a moire pattern is displayed.
Enabling/Disabling G-Sync makes no difference. Lowering refresh rate from 144Hz to 60Hz makes no difference. I even tried different version of GeForce driver (I'm using GTX1070 card on Win10 system). Nope, it doesn't fix anything.
Isolating the DisplayPort (or even my whole PC), I use HDMI to connect a video player and the monitor. Nope. It's still the same. So it's not my computer or DP/HDMI issue. It's the monitor itself going crazy.
The monitor warranty will end soon on July this year. When checked in Dell website, the warranty status says: "Advance Exchange - Next Business Day (8x5), Limited telephone technical phone support". What is 8x5? S2716DG is no longer listed my country's (Malaysia) Dell sales webpage. How will Dell exchange my unit on next business day if there's no stock locally? Or will I get a similar replacement for what I've paid previously?
Extra info: Found this defect on Sunday (May 19th, 2019). Tried to do a webchat on Monday (May 20th) but failed because it's public holiday here.
I have attached a few photos here. Please ignore the wavy/curvy moire that is caused by the camera of my smartphone.

* For my Dell notes, click my name and private message me the S2716DG service tag number and 20 digit alphanumeric serial number
* From whom and when did you purchase this S2716DG?
* We must see pictures of the stand alone (disconnected from PC video card) S2716DG Built-in Diagnostic colored screens. Based on those pictures, I will tell you if the S2716DG meets our manufacturer specifications for overall uniformity

Hi Chris,
I have PM-ed you. Too bad my smartphone camera can't capture the defect clearly, especially those RGB page.

Based on the Built-in Diagnostic colored screens you sent me via Private Message, we could not exchange this. Now, we are in the USA. You could certainly contact Dell Malaysia and get their opinion.

What? What is the reason? The defect is clear enough as shown in the photos uploaded here as well as the built-in diagnostic color test that I've PM-ed you.
It's very obvious on the 1st test color because it's greyscale, easier for my camera to pick up too. R/G/B/black/white are too intense for my camera to show the fine details.

Based on the Built-in Diagnostic colored screens, this passes our manufacturer uniformity specifications. It is acceptable for the corners, sides, bottom, and top to differ from each other or the center and still be within manufacturer specifications.

If more than 2/3 of the screen is defective and you call it acceptable, then I would not buy any Dell monitor in the future. That's extremely poor QA standard. To make thing worse, you make this judgement based on a few poor photo shoots without offering a technical staff to inspect it physically.

* Dell has never sent onsite technicians to troubleshoot monitors. Onsite technicians are only sent out to replace parts in a computer.
