Dobr,

There is no user control over the overdrive RTC (response time compensation) impulse within the monitor OSD menu.

Re: u2413 Is there any way to turn off RTC?

Oh no ... really? It's happening on this monitor too? I have the Dell 2740L as well which has this issue and I thought it wouldn't happen to this model. It's really bad on  the 2740L, and Dobr and nokey (another post thread) captured the exact way it shows up in photos on the U2413. I just placed the order for it today [Dell U2413], I think I will cancel it now. What shame, I planned on using this side-by-side with my Dell 2005FPW. FYI: I had the 2410 -- returned that in a week, I had bluish tinting and horrible AG coating. It's like ever since they moved away from Samsung to LG, their monitors have gone from good, to bad, to worse. You're right, doesn't ANYONE actually take the time to sit in front of the monitor and see how it works? Terrible. Absolutely terrible.

Are there any plans to have an on/off overdrive option? I'd like to know so I cancel or keep this pending order. Thanks.

Re: u2413 Is there any way to turn off RTC?

Hi adobepro,

I wanted upgarde from U2410. But U2413 have this bad overdrive. U2410 have some minor ovedrive problems too... ( I think that too high ovedrive this is specialty of all Dells monitors) but U2410 have only bad some  transitions from dark to light shades. Transitions from light to darker shades are ok...

U2413 have high oveshoots in  transitions from dark to light shades but adds  very ugly undershoots on  transitions from light  to little darker shades... this produce very ugly anomalies on light scenes.:emotion-6:

And the worst thing is that there is no possibility to disable it (there is no option in OSD menu for overdrive ON/OFF). So my advice to you is:  Cancel the order. if you don't like inverse ghosting (maybe Dell making monitors for inverse ghosting fans:emotion-2:).

EDIT: This monitor (like U2713h and U3014) is good only for static pictures with possibility to produce accurate colors (photo editing). On the other hand, moving content on this monitor is very bad (games, movies, animations).

Re: u2413 Is there any way to turn off RTC?

Thanks for your reply nokey -- I think I may have found a crude "solution". On my Dell S2740L -- I set the brightness to 100% and set the contrast to an acceptable 40%. When I scroll webpages, the inverse ghosting is not too bad -- it's just slight fast blur. Originally, webpages and skyrim were REALLY bad. I'm wondering if it also has to do with PWM when you set the brightness lower than 100%? I'm going to let the order go through and fiddle with it to see if I can manage with it -- worst case, I have free return shipping. I might try softmccs and see if I can do anything with that to turn off overdrive. Thanks again for your reply and comments -- completely agree....such a shame. It really makes me wonder if anyone in Dell actually sits down and uses the monitor rather than just staring at a static image to see how the monitor performs before going into contract to sell these units with the Dell brand name. As for the U2410 -- I couldn't stand it! I used it twice for about 10 minutes, waited a week to give it one more shot, and yes, that monitor was THAT bad. Horrible tinting and horrible AG coating. They fixed that, and now have this. Wow. Doesn't Dell have anyone in the company that can see what's going on? There are problems, and unless Dell is aware and they just don't care, esp. with who's buying who (going from public to privately owned company), just sell, sell, sell under the UltraSharp brand that had a great reputation to keep shareholders happy, and/or there really is no more quality control and no one cares.

Apathy at it's finest!

Re: u2413 Is there any way to turn off RTC?

I was looking to buy a couple of high-end Dell 24" UltraSharp monitors, but after some casual Internet research, looks like the new u2413 is off my short list. This is not some entry-level monitor ... the u2413 is suppose to be the best 24" monitor that Dell can make.

So that everyone knows what we are talking about:

Initial reviews of the new 2013 top-of-the-line 24" UltraSharp monitor are poor. People are complaining of OverDriven images and inverse ghosting. This "u2410 replacement" should be able to handle fast images (movie editing and playback, CAD animation, game development and testing) as least as good as the u2410.

See Detailed Review here:

Some of this is pretty technical. Search article for keywords: RTC, motion blur, overshoot, overdrive, Responsiveness and Gaming

www.tftcentral.co.uk/.../dell_u2413.htm

Hopefully, these issues can be resolved. It seems that the RTC algorithm needs adjusting. Other monitor manufacturers give some user control of RTC (either on/off or variable percentage). If and when a new Revision Level is released, I suggest the Dell reach out the TFTCentral and others so they can re-test and update their reviews.

More Links from casual Internet search:

User Kundica returned their's due to poor display uniformity and connectivity.

Looks like the below thread got locked (but see Nokey's examples there).

This one is still unlocked. Shared u2413 and u2713h data should probably go here

If I find any more u2413 specific data, I will edit this post or post it in this thread. Last edit 3-29-2013.

Re: u2413 Is there any way to turn off RTC?

Thanks nokey and Telsa1856

nokey: I'm wondering, can't we do a firmware update via usb / softmccs to fix the overdrive? I find that having to ship a monitor to a repair facility to fix this issue is barbaric, prone to physical damage during shipping and handling (I assume you don't get your monitor back, but a refurb unit with the new firmware,) and a waste of time and money for everyone.

Telsa1856: Sure, as soon as I get it, I'll post the Rev #.

I know there are other issues with this monitor, but come on, this is basic. I find it hard to believe any 5 star reviews on Dell suggesting how good this monitor is when such a basic function of the monitor is piss poor. Scrolling a webpage should not look like this. My $100 viewsonic at work has better performance. I don't even have the monitor yet, but I'm making this claim based on the S2740L and what DELL-Chris M said: "All of the Uxx13 will have the same design. No, this design is not going to change. No, there will not be firmware to change this design." Once I get the monitor U2413 on Monday, you'll have my confirmation as well.

Wow, such a brash statement if you think about it:  "All of the Uxx13 will have the same design. No, this design is not going to change. No, there will not be firmware to change this design." We are paying customers. We give you money and we have certain expectations of the goods you sell to us. I'm a software engineer, and if I developed and sold software like this, I'd be out of business. I'm not trying to start a fight -- but listen, this isn't charity. For a $500 monitor, we do have certain expectations that basic functionality should work perfectly, or at least comparable to a $100 ViewSonic.

Re: u2413 Is there any way to turn off RTC?

OK, I got mine today -- it's Rev A01, and unlike the inverse ghosting on my S2740L (the text when scrolling on a web page becomes "crinkly", the text and all images have this bluish/cyan tint to them above/below -- e.g., when you scroll down, there is this bluish/cyan tint underneath the text/image -- scroll-up, there is bluish/cyan tint above. My 2405FPW (my mistake from before, I don't have the 2005FPW, I have the 2405FPW) doesn't do this. Another really annoying thing about this monitor is when watching video, the entire screen shifts brightness/contrast (or color temp, can't really tell) from my setting to a darker setting. My current setup is DisplayPort to GTX 680 / sRGB. I'm going to play with this for a few days and see how things go. I will say this though, the AG coating is perfect, 1000x better than the U2410 and actually better than my 2405FPW.

Re: u2413 Is there any way to turn off RTC?

I tried all the modes, including AdobeRGB, and the same ghosting appears as well as the color temp or brightness/contrast changes during the playback, e.g., for n-seconds it's one color "hue", and then it changes depending on the lighting in the movie. If they could fix this, I'd strongly consider keeping it. At this point, I will most likely return it this week. Static photos look great, but anything that involves motion, the monitor acts wonky like this, esp. with video. One person on the review for this monitor make sure cables are tight/good GPU. Aside from a firepro/quadro, I think a GTX 680 is a darn good card. The DisplayPort connection couldn't be any tighter. It's the monitor.

Re: u2413 Is there any way to turn off RTC?

OK -- I figured out how to get the video to work properly, after I opened the Dell Display Manager (I usually just keep it off) and played a video, I got a dialogue for "smart video enhancement" -- I disabled that and the color shifting doesn't happen anymore.
