U2715H, Ghosting, normal or not?

Hi, I´ve got this monitor (DELL U1715H) for my studies task and 1440p non-competitive gaming.

I´ve been using the monitor in gaming properly. However, in my last game Rime, I'm able to detected some ghosting issues over the blue sky.

So I tested ghosting with test UFOs, and my monitor seemed OK. But then if I test ghosting with CYAN o MIDDLE GRAYS background color, the ghosting inverse or overshoot is slightly visible. Obviously I'm using NORMAL Response Time (FAST is even worse).

(In photos is less visible than real vision)

In most usual conditions o games, it hadn't been a real problem for me, only at Rime, because of minimalist graphic style with plain textures. 

Finally I'm worried because my reference review of Dell U2715H by TFT.central said at Normal Response Time it shouldn't show any overshoot or ghosting inverse. Maybe my unit uses a more agressive overdrive internal setting or simply this low level of overshoot is normal? So, what about you? At least, ¿a more agressive overdrive means a lower overall response time?

My DELL U2715H Rev. 03, Manufactured Sep. 2016.

Brought Feb 2017.

RE: Dell Ultrasharp U2715H - GHOSTING INVERSE: Is it normal this monitor has a bit of overshooting?

There have been some reports of some ghosting, but all returned have been inside our manufacturer specifications. Sometimes ghosting can be caused by incorrect aspect ratio. Go to your video card control panel settings and make sure that the desktop scaling is set to scale based on 16x9 aspect ratio.

What computer model?
What video card?
Did you install the latest video card driver?
What video out ports are on the video card to test?
What computer to monitor cables are you testing?
Factory Reset it =
* Press the Menu button to open the OSD (On Screen Display)
* Go to Others- Factory Reset
Test all of the U2715H video in ports (HDMI/HDMI/DP/mDP)
* Change to Preset Mode Game and test with Dynamic Contrast On

RE: U2715H, Ghosting, normal or not?

What computer model? - Asus Z97A, i5 4670k, 8GB RAM

What video card? - GTX 1070

Did you install the latest video card driver? - Yes. I dit it.

What video out ports are on the video card to test? What computer to monitor cables are you testing?

- I'm using HDMI cable, because it was longer. But I could try DP then. ¿is it possible overshoot changes via DisplayPort, instead HDMI?

Factory Reset it =

* Press the Menu button to open the OSD (On Screen Display)

* Go to Others- Factory Reset.

- I dit it.

Test all of the U2715H video in ports (HDMI/HDMI/DP/mDP)

* Change to Preset Mode Game and test with Dynamic Contrast On

- I've just tried it. But all modes show same ghosting.

Yes, I have tried changed all setting about scale and aspect ratio, without changes. Then, do the most of Dell U2715H look similar? And then I should considerer my level overshoot normal and deal with it.

Rest of users Dell U2715H may test it, thanks:

RE: U2715H, Ghosting, normal or not?

When running that test at its defaults =
Cyan, 160 pixels, UFO, On

My UP3216Q shows some ghosting. But I do not see ANY ghosting in games. So the test fails for me as a false/positive result.

RE: U2715H, Ghosting, normal or not?

Yes, so do I before. But I discovered ghosting could be a problem, in RiME (Tequila Works). Here you are a gameplay, where I'm able to detect visible ghosting on outlines of trees.

You are welcome to try through support to get an exchange. Test the replacement. If it does not have the issue, return the original to Dell. If the replacement has the same issue, then the fault cannot be with the monitors.

RE: U2715H, Ghosting, normal or not?

I've been doing test. I have just checked "test UFOs" on a friend's simple IPS monitor, and light trailing behind UFO was visible too in this test. So in this respect there is no problem.

But main anomaly really is trailing when I scroll windows websites with determinated background. This problem wasn't shown on the friend's monitor, but yes in mine. It's noticiable on background gray, and it's shown a bright trail behind of figures or text. Besides, some trailing shows a pink o green tint. However this latter happens only on Standard Mode (pre-calibrated)" that I think it may be due to how pre-calibrated mode has been set. But in any way, the trail is big and visible.

I have found other Dell U2715H samples with similar problem:

Or:

And I'm not sure if these are some faulty units due to some REV 03. Or this is only a distinctive feature what we would have to know and it's normal. I'm confused. Really I don't believe a such good good awarded monitor may be this.

It's difficult to me a easy replacement to try because I'd bought the monitor on Amazon.es (Spain, my country), and besides Monitor Service Tag number is identified by Dell Support in another region.

I'm sure if my monitor is really faulty, Amazon.es could give a new replacement, in any way. But not a replacement for simply to check or to try.

RE: U2715H, Ghosting, normal or not?

I have got a new surprising inquiry!

I have changed on OSD Aspect Ratio from 16:9 to 4:3 and after have gone back 16:9 (this should be same), but after... The ghosting inverse and big trailing are fixed! I checked UFO tests and scroll windows websites, and now trailing seems OK. It is forcing TRUE low overdrive for response time.

However, when I put off monitor, the trick is reset, and another I see overshot.

Definitively, it's demostrated default Mode Normal wasn't working properly. This is like a OVER-NORMAL, a more agressive setting what produce noticiable ghosting inverse.

So, maybe now some REV 03 units are suffering this unwanted bug. Maybe Dell think the new more agressive overdrive is better, maybe they have changed the model of the panel...

Now I think I should to try a new replacement if Amazon.es accepts, although maybe it may work same bad way.

Regards, thank you.

RE: U2715H, Ghosting, normal or not?

I have just received the replacement, and it's all wrong anyway. SAME PROBLEM.

Definitely, it is not a proper monitor for gaming, even singleplayer. Anything has changed respect to first reviews.

Shame, because image quality is unparalleled.

I can confirm this method of changing the Aspect Ratio in the monitor Menu temporarily fixes the ghosting.
