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.

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

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 U2715H look similar? And then I should consider my level overshoot normal and deal with it. Rest of users U2715H may test it, thanks:

Color Background: Cyan 

Thanks for you reply. Regards

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.

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.

Regards.

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.

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 noticeable 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 revision A 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.

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 toggling back and forth, 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 demonstrated default Mode Normal wasn't working properly. This is like a OVER-NORMAL, a more aggressive setting what produce noticeable ghosting inverse. So, maybe now some A03 units are suffering this unwanted bug. Maybe Dell think the new more aggressive 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.

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 was going to buy this monitor. Was the issue fixed by some firmware or by some revision? Ghosting is unacceptable for me.

I bought this monitor 7/16/18 and still have serious ghosting problems. You can see them in the pictures:

Its the rev A05. September 2017.
