Dell Ultrasharp U2413 Inverse Ghosting Issue
Hi Chris,
First of all, Thank you for coming back to readdress this issue.
For some reason I couldn't reply to the previou
s thread 'U2413 has green reverse ghosting' and so had to start a new topic on the subject.
As of now I have two A00 revisions of the Ultrasharp U2413 on my desk, both exhibiting the exact same problem. Here are the details:
S/N: CN-084K96-72872-39D-CFLL (Manufactured September 2013)
S/N: CN-084K96-72872-3CR-C05L (Manufactured December 2013)
A00 (both)
Desktop
Geforce GTX 770
DVI / HDMI / Displayport
Driver version v. 335.23
DVI to DVI cable
Windows 7 64bit
I recreate the problem easily when on the sRGB preset at default 50/50 brightness/contrast by simply scrolling through a webpage of text on a white background. This issue is at its most horrific and noticeable when panning through Google maps in a browser.
With all due respect this really needs to be fixed by Dell now, I am a motion graphics artist and have paid a premium for a what I thought was a decent monitor for my graphic and animation work. A firmware update to mitigate this RTC overdrive or whatever is causing the inverse ghosting is needed.
The issue seems slightly less apparent in the Standard Mode, with the ghosting appearing less saturated in colour but still apparent like a drop shadow. However, I need to work in the colour accurate sRGB mode in which this problem presents itself at its worst.
As it stands, it is unacceptable for me and I will have to look at return both of these if I can't find a solution.

This is quite heavily compressed, but I can send a .mp4 if required.

This will be not fixable with firmware and its present since the first units in feb 2013. If it is unusable for your work return it for refund and get an Asus PA249Q (0% overshoot issues) but this one is not LUT3D calibratable by user like U2413 (but has 2 Custom modes in OSD for GPU calibration in its native gamut). BenQ PG2401PT equivalent to U2413 suffers from mild overshoot and undershoot issues. U2413 does not have undershoot issues.
These are your options... or try get a premium monitor fron NEC or Eizo for 3x the price.

Thanks for your suggestions here yumichan... its a great pity that there isn't a direct alternative to the U2413 out there, at least not at the same price point!
The thing is that I had an LG panel several years ago that had a terrible red tinted ghosting effect which was completely fixed by a firmware update at the time.
I reckon Dell could do something similar if they were motivated to do so. At present, it seems they're having a problem even admitting this problem exists - Chris on the forum here says they can't seem to recreate the problem in a lab, which is quite strange as it took me only minutes to detect with both monitors I have.
I don't doubt that this sort of thing will give Dell a bad reputation in the long run.

Chris said that it is "electronic" related, not configurable with firmware but IDNK.
