Does anyone know how to activate the factory screen for this monitor? If only it had a gamma setting hidden in there... if only.

Thanks for the info. I hope i dont have to send it back, it works well otherwise, and there's no dead pixels. Just when the monitor sleeps it will just start cycling through full screen and very bright, RED, BLUE, GREEN WHITE instead of just going into a power save mode. I have 100's of dell monitors at at work, and i've never seen any of them do this.

I've seen this behaviour on the Acer XB271HU, it's the factory test activated from the service menu, I think it's actually nVidia's service menu. It worked only with DP disconnected and DP sleep off in the OSD. The key combination to open the menu doesn't work on this Dell unfortunately. Maybe someone forgot to flip the option in the factory wink.gif

Thanks for the info - If you see what the code is, or if anyone knows. Please respond here. I'd like to avoid sending it back and getting some other returned display. This one has no dead pixels and is otherwise working well.

I'm still so angry at nVidia for not having a temporal dithering option in the control panel. On Linux, you can enable it by simply editing a plain text file. This one option would solve our color banding issues. I've been searching high and low for a way to turn this on. If anyone find out anything, let me know. I have a feeling that if you could trick the control panel into thinking your monitor is a built-in LCD, it might show the option then.

So after backlight on my Dell broke (a bright spot in the lower edge that could be temporarily fixed by applying pressure to the frame, but popped out after 5min again) I've since replaced it and there are some differences.

First of all, calibration is acting very weird. It requires very different settings than the last one (13 brightness (vs. 20) 79 contrast (vs. 74). This one not only has TN's gamma shift, but something I'd call gamma drift. It starts with 2.15 and as it warms up it changes up to 2.25 after a few hours. I've performed calibration after it's been on 2h. Also the contrast changes along with the gamma from 750 to 830...

I've tested more of 3D LUT for ReShade and I've found that the standard setting of Tone curve Rec. 1886 with gamma 2.4/2.2 is not giving the best effect. I've used Tone curve: Gamma 2.2 with gamma 2.2. The difference is staggering. Diablo III looks very, very good with it now. Other games, that are less gamma-dependant, are not affected that much.

This, however is nothing compared to what happens when I launch Visual Studio 2015 with the Dark theme biggrin.gif

dell_wtf1.zip 4519k .zip file

This happens not only when I view VS, but also viewing the screenshot if it! I can see it to a lesser degree in games as well, which don't use calibration, especially on the loading screen of Diablo III.

I've eliminated some possible causes:
  • G-SYNC, refresh rate
  • calibration, video LUT
  • monitor settings
  • interference from other cables - unlikely since it's DP
  • it doesn't seem to be the system/GPU's fault since the same picture on a 6-bit Dell IPS on DP is stable

Any ideas what it actually is? I'm not sure if it's pixel inversion, it's visible even on very small amount of the gray colour from the VS background.

Turns out it was the GPU after all. One out of 3 DP is behaving like that even when I connect the IPS to it. I am really surprised that it's possible to have a DP signal corrupted like that.

I have to redo the calibration now...

Edit: One more thing changed, the monitor now flashes dark green/black when changing modes. I haven't had any previous G-SYNC monitor do that.

Guys, i send it back because already found 5 dead pixels and always this backlight bleed starting from bottom right corner until mid, very annoying on dark environment.
Maybe this is the reason (check
on picture)
i figured out a set with 20 brightness and 50 contrast to avoid stain eyes on desktop work. This screen was very very bright.
I will give u feedback for the new one.
My monitor was manufactured october 2015.

Yeah, I'd say the majority of the bleed people are seeing is from the bottom right. There must be something up with the construction in the area. Trying to pack too much electronics in there or something. On mine, the bezel is a bit removed from the rest of the monitor and I do have slight BLB from down there. By slight, I mean you really have to look at it and then look at the other corner to tell there is a difference.

Hi all,

does anyone have issues with pixel inversion with this monitor? Had a bit of pixel inversion and returned it. Yesterday i've tried a Asus PG278Q and it was horrible the pixel inversion was clearly visible. Much more than the Dell.

Want to buy a new Dell. Or is this a rare case with this monitor?
post #1840 of 4826
well I don't see pixel inveriosn on mine.
