U2718Q, DP cable, green is not correct

The green looks great in that picture?

* To what computer model, video card, operating system are you connecting the U2718Q?
* You should be using the supplied Mini-DP to DP cable that shipped in the U2718Q box
* Open the U2718Q User's Guide to page 51
* Follow the instructions to run the U2718Q BID (Built-in Diagnostics)
* Post a picture of the BID green screen

Yes green from that picture! From 51 page diagnostic not helped!

Problem when connect with DP cable, when connect with HDMI all fine.

Videocard AMD

Radeon Pro 555 2 ГБ, Macbook 2017, OS and WIN the same with dp cable

Problem with GREEN GRADIENT. 

Then calibration hardware and software are the only alternative.

From a warranty perspective, the BID green screen passes. We cannot exchange this monitor. You have two options =
* Purchase 3rd party color calibration hardware (colorimeter) and software and calibrate the monitor
* Return the monitor for refund

Can't return because with HDMI work fine, and they say, monitor ok, this problem only with any DP or mDP cable! And this "bad pixel test" not professional for professional display!

No calibration is not the answer!!

I purchased spyder5Pro and I also used DisplayCal software  No use!!!

No resultat?

kostasfi,

Are you saying that calibration by the Spyder5 Colorimeter hardware and its software failed to "calibrate" the monitor colors?

Not sure. But if your BID green screen also passes, Dell cannot exchange it.

Hi @Denimsmurf

Do you still own the Dell U2718Q monitor? Dell just released a new driver-update.

Could you check this driver-update to see if this solves the green on DP issue for you?

Hi! No, returned monitor to shop and buy LG 5K without any troubles. Hope in future Dell will think in advance about customers and dell products. And test products before.

I put a lot of trust in Dell and their calibrated displays (I personally own several and we order them in bulk at the office).  The photo from the poster shows that green was not showing the expected gradations for an sRGB color-calibrated display (or even an non-calibrated display for that matter). The user should not be told to calibrate the display themselves when the monitor itself fails to meet the color calibration standards included in its box. I do realize that you just posted a firmware update which fixes this. For the OP, here is the firmware update. I realize that you have moved onto a different display.

Tried it earlier today.  It appears to work.
