We are aware of the complaints. We submitted the issue some time ago. The Displays team stated that there are no plans to give the user the ability to turn RTC Overdrive off.

* If installed, open the DDM (Dell Displays Manager)
* Click the tab Auto Mode
* For every application listed, change them to Standard
* Press the Menu button to open the monitor OSD (On Screen Display)
* Open Display Settings
* Highlight Smart Video Enhance
* Change it to Off
* Open Color Settings
Input Color Format = RGB
Gamma = PC
* Open Preset Modes and test each one, Standard, Multimedia, Movie, Game, Paper
* Exit the OSD

Chris,

Thank you for the quick rely. Unfortunately, your recommended settings don't help at all because my monitor already uses them. I believe these are factory default settings.

Did you test every Preset Mode? Did you test all available ports (DP, DVI, HDMI) ?

Does using DP1.2 solve ghosting and lag problems? I tested all port and setting of course, as this is an expensive hardware, and intend to achieve optimal use of, if not, then would buy a cheap display. Then display port 1.2 enabled on a machine that support full res (MBP late 2011 nvidia), display is blank. using older mbp that doesn't support the res on setting to DP1.2 work ok. ghosting and response time noticeable and worse than screens in half price is unacceptable, plus screen do not wake up with computer now and then. Waiting for replacement.

FYI - nVidia did not support DP 1.2 until the very latest drivers (released 1-2 weeks ago). At least on my PC, GTX 670 DP 1.2 works now. Not sure about the Mac situation.

Ugh, that is bad. Can you ask again? Because those displays are unusable with it enabled.

Their decision has not changed.

Can you explain the reason for this decision?
It is a design specification from the manufacturer.

Can you explain the reason for this decision? How does having this aggressive overdrive implementation improve image quality, color reproduction, or any other aspect of the monitor's operation, etc? As it stands the monitor could only be improved, especially for those of us working in pro imaging applications, with the option to turn this "feature" off. Try working and moving around a grayscale image in photoshop to see just how negative an effect this has on visual clarity.

Best regards,
Claudio

Yes, I tested all modes. No help. My current solution for this headache is I bought a cheap monitor as 2nd monitor at half cost of U2713H. No more ghosting while scrolling! My other nit for Dell monitors is the color is too warm no matter how I calibrate it. By the way, I just recently noticed that my XPS L502x laptop with1080p screen showed ghosting too while scrolling. All these products are top line. Dell, I just don't know what to say. (I'm lz1234.
