This is info from Chris, regarding 2413, so i suppose that same thing will happen to other screens as this is software issue.

U2413 part number FJMKT has revisions A00, A01, A02
A00 = Initital release
A01 = LCD panel version number change
A02 = corrected the inverse ghosting due to too much response time compensation overdrive and USB 3.0 issues
* We received word that the factory is not changing the PPID serial number label. They are fixing them on their end but it cost too much to generate the new labels. All New U2413 purchases regardless of the revision on the label should have the internal A02 fixes. All Used/Refurbished U2413 Dell Outlet purchases regardless of the revision on the label should also have the internal A02 fixes. Of course, none of the resellers will have these fixed monitors

U2413 part number XTXXK A00 (4/15/13)
A00 = Part number XTXXK includes all of the fixes in the old part number FJMKT, A00/A01/A02. Of course, none of the resellers will have these fixed monitors

Hi,

Just received and installed a replacement for my Dec2012 U2413. I received an Aug2013, Rev00 (but can be anything)

Looks like there IS still inverse ghosting (same as before, perhaps a little less). How do I know what real revision I have? Does it make sense to return it again?

Thanks.

My replacement monitor is also Aug 2013 (got it today, replaced for another reason), Rev 00 and I can confirm there's still the same ghosting when dragging windows / scrolling web pages I've seen on my previous A00 April 2013. According to other posts that's the case across the board and Dell said they won't be fixing that. The original issue pertained to ghosting in movies/games which I never saw.

Seems like that's the case.

So, what have they EXACTLY fixed with rev.02 ??

I i were you i would change it 50 times if i have, until they send proper screen. If you can get refund and buy u2410 or 2711 these screens are way better than u2413 will ever be. This monitor is around 500 euros in my country, that is really a lot and one can expect at least fully working screen.

the funny/tragic thing it that I wanted to buy a 2410 or a 2711 for years, at the end I found a deal for a 2413 and thought it could only be better than previous one... thus I bought it... great mistake only to have led backlight...

To be honest this screen is better than the previous... The ghosting looks less than before, and at least this has a more uniform color,  the old one had green zones in the low left of screen... Unfortunately looks like has less vivid colours,  that was the only thing I liked of the old one...

"RTC overdrive on light backgrounds
* This is by design and will not be addressed"

Found here http://en.community.dell.com/support-forums/peripherals/f/3529/t/19507654.aspx

Overdrive is poorly calibrated on the u2713hm monitor also.  "If" it's by design... Just wow.
