I would love to know more detail on your workflow so I can try and recreate a decent profile like yours but would need to pick your brains as I have so many questions. Maybe over PM, if that is ok with you?

As I have the i1display pro the retail software for mine will be different than the colormunki. Also my calibration device may have degraded as it is around 2 years old but I would suspect that the device itself wouldn't deviate so rapidly in a relatively short space of time with little use.

This is the best I could do using DisplaycalGUI alone. Low calibration speed and
max test chat

I'm happy that you got a better result smile.gif

As to my workflow it's basically what I've written before: getting the OSD settings right with ColorMunki software and doing the final profiling with displcalGUI.

It's important to remember that relation between brightness, contrast and RGB gain is a complex one. For example the ΔE can be good at two set of settings, let's say 20 brightness 70 contrast, 85/87/90 RGB and 25 brightness 75 contrast, 95/96/98 RBG. While colour accuracy can be similar the final contrast may differ at both of them. I'm not sure you'll get what I want to say: this is a complex issue with many possible solutions that result in different ΔE and contrast. Not to mention that each panel is different . Getting exactly the same results might be impossible wink.gif

I'm not sure about i1display pro software, but an important part is setting the right corrections for the backlight type. By default X-Rite's software assumes CCFL for some reason, even in the latest version. In ColorMunki you can change that by going File -> Preferences... and selecting White LED as the type for this monitor. I'm also disabling Achieve display luminance value using video LUT. The reason is that I want the software to adjust the monitor for optimal luminance, and not do it through the profile, since we're throwing that out anyway.

In dispcalGUI I'm using Correction: Spectral LCD White LED IPS (WLED AC LG Samsung). I think it's getting it out of X-Rite's package at first run. I can't check right now since I've loaned my Munki out wink.gif I don't think I can post due to copyright by X-Rite. The file name is WLEDFamily_07Feb11.ccss.

I've tested both ASUS PG279Q and Acer XB271HU before settling for the Dell. While the IPS panels have their advantages (good out-of-the-box colours, better viewing angles, less grainy AG coating) they have disadvantages as well (the models I tested are plagued by quality control issues - BLB and excessive yellow/orange IPS glow are common). I would advise you to read through this thread, the ASUS thread is not really worth it since it seems to have worse QC than the Acer - read that one instead.

This Dell requires quite a bit of work to get the gamma and colours right and the AG coating is a bit heavier. It's got the fastest response times so you can freely use G-SYNC instead of ULMB that I had to use on the IPS to keep the motion blur away. Don't get me wrong, those IPS (AHVA really) are the fastest IPS available, but they still have more motion blur than a fast TN. S2716DG doesn't have IPS glow as well so dark content looks "better".

There is no perfect monitor technology, IPS, TN and VA all have good and bad sides. It'd be best for you to see them all in person.

Also want's to get his monitor but unsure if it's really a step up from my qnix. I have 980 ti so I already gain the G-sync part of it and that's a huge plus in my optinion. not having to worry about FPS so much

I have 970 atm and I will upgrade to 980 or 980 ti soon.Do u think gsync is worth it compared to 144 hz without gsync?U dont have tearing so whats the point?Only for smothness with fps drop?Are 70-80 fps bad with 144 hz monitors without gsync?

you will get tearing no matter what if you don't have vsync enabled but with vsync enabled you get microstutter instead of tearing so yeah it's mainly for smoothness. I get why it's smoother. for example I play bf4 and get my 110fps but I get frametime spikes although my fps is the same. So I can imagine gsync makes everything smooth as long as you get a decend fps. A970 will struggle abit but at least when you uhave g-sync you don't have to worry to get 144fps to maintain somewhat smoothness

Hey guys, I recently built a new gaming PC with S2716DG, got 1 dead or stuck pixel (don t know..) but it doesnt affect the display quality since it is on the top left corner and it s very very small. Build quality is great
Don t know yet about pixel inversion or vertical line since i am noob biggrin.gif
It s my first entry on the 27' with 144hz , coming from 17' 60hz..
Using the resolution of 2560 x 1440 at 120 hz, G-Sync on 980TI.

I am gonna read all this thread and hopefully I could get good looking colors for this monitor because in desktop mode (excel, word,browsing..), the brightness and policy are killing my eyes mad.gif
Settings are default on nvidia control panel but for osd dell: brightness 25% and contrast are set to 50%, dell icc profile.

the screen seems overly bright to me and cause eye strain and headache,

What settings are people running on their Dell?

I use the GTX 970, in many games there is significant framerate differences from scene to scene, especially since this is a pretty high resolution of 2560x1440. I'm definitely an enthusiast level computer/videogame guy, but I can tell even with g-sync what general frame rate band i'm currently in, but in all cases the tearing is gone, the picture on the screen is always correct, with none of those annoying lines that would form otherwise. In GTA 5 for example, flying an airplane, I would always see horrible tearing, where as now no matter what frame rate grouping i'm getting the picture is free of artifacts.

If you were rich, and were using two or three 980ti's in SLI, then you could maintain 144fps in games and not need g-sync, but if you were rich you'd still get g-sync because it's just better. There are plenty of games now, and in the future that will cause your frame rates to be low enough for tearing to appear. I consider this worth it, not only now, but because always going into the future tearing is a thing of the past.

Generally I think a stuck pixel is considered a pixel that's always on with one color, like a pixel that is always green, and a dead pixel is one that is always off or dark.

The screen won't look right till you go to nVidia's control panel and tone down the gamma setting, or try some of the ICC profiles people have posted. Every monitor is different, and its highly likely none of the ICC profiles or nVidia settings configurations will perfectly match your monitor, but they could be a good starting point. To date, i've spent hours messing with settings to get the monitor to a better and better point, and i'm not even done yet.

When you decide to start messing with the gamma and other settings, or the ICC profiles, navigate to http://www.lagom.nl/lcd-test/ and check out the various test pages, especially the gamma page, and the black level page. I highly suggest you consider not only what you're seeing on the lagom website, but also what feels best to your eyes as well, since your enjoyment is the ultimate purpose here.

As for the current settings I am using, they are as follows (although as I pointed out, I'm not certain i'm done yet)

OSD:
35 brightness
72 contrast

NVCP:
45 brightness
40 contrast
0.67 gamma

With these settings I do lose the final shade of gray (square 1 in black levels page), however in general the black levels are better and banding in dark areas is less noticeable with this panel/setup.

I just don't understand how setting the brightness and rgb values first in colormunki's software and using softcmss to set the values (which you can do from the osd anyway) is any different from doing it all from DisplaycalGUI. If the colorimeter was placed centre on the screen then I just think you have a better panel.

I do experiment with settings like you have described and run the "report on uncalibrated display device" option. That way I can see which gives the better results and then I start profiling from there on.

Displaycalgui imports the spectral corrections and the one you mention is what I use as well.
