Over the last days I've been playing around with the color settings a lot. With the help of an XRite i1Display Pro I've tried to come up with some balanced 6500K color temperature settings for the S27A950D.
I've found some differences with the suggested settings courtesy of SeanPoe, especially the blue level of those settings seemed too high on my unit after profiling it with the colorimeter.
For the impatient, the following is what I came up with:
- Magic Bright Standard (as starting point)
- other Magic settings off
- Brightness 40 (about 120cd/m²) to
- Brightness 0 (about 53cd/m²)
- Contrast 82
- Response Time: Normal
- Red 21
- Green 23
- Blue 15
- Gamma Mode 3
- Brightness 100
- Contrast 82
- Red 45
- Green 35
- Blue 14
- Gamma Mode 3
So now some explanation is due, right? Well, this will get lengthy so please bear with me.Color temperature:
The settings will lead to a rather ideal linear color response towards a target color temperature of about 6500K in 2D and about 7000K in 3D and a luminosity of about 120cd/m² in 2D and about 70cd/m² in 3D. 6500K is about regular daylight on an overcast day at noon, so if you view some photo on paper in that kind of light, it should look similar on your Samsung. The midrange is a tiny bit emphasized but that's because of the display itself and I couldn't iron that out without a proper .icc profile. Speaking of profiles, sadly XRite changed their EULA this year and now its forbidden to post the created .icc profiles on the net without a special license from them, which I suppose costs a pretty sum of cash. Kicking in the created profile only showed really minor differences that are hardly noticable though so it's not that bad in the end. Wikipedia has an explanation
about color temperature that might be worth a look if you're interested.
With the originally recommended settings of
Red and green showed an almost linear response towards 6500K but blue colors were about 10-15% more intense than they should have been, making the overall color temperature much colder than my desired 6500K. The profiling software is more targeted towards making .icc profiles so I can't really say what exact color temperature those settings get you.Brightness:
Normally I'm gaming in a pretty dark environment so 120cd/m² is some sort of retina torch mode for me. Currently I run a brightness of 5 which is about 60cd\m² and is pretty comfortable while typing this wall of text.
There's another reason why I'm using such a low brightness level and why the RGB settings are somewhat low which is more of a workaround.
Measuring the maximum luminosity in 2D mode showed about 300cd/m² but 3D mode revealed a shocking 70cd/m². Ouch!
This means as soon as the monitor enters 3D mode the luminosity is heavily reduced resulting in a darker image, albeit the brightness is cranked up all the way to 100. Since my 2D settings are even a bit darker than the 3D settings now, the luminosity drop is not that bad in the end.
The only reason assumption I can come up for this is, that the backlight is being pulsed in 3D mode to reduce ghosting. This would be very much like what NVidia claims to do with their new 3DVision 2 tech.
The really weak luminosity in 3D mode is also about the only gripe I have about this monitor. This new Lightboost stuff built in the new NVidia certified monitors sounds promising but I haven't yet seen measurements of it yet.Contrast:
The profiling software mostly came up with 82 as the optimum value. If you increase contrast more and more the image seems noticably brighter but you also can't distinguish different shades of white as everything looks the same. It just gets overly bright and unpleasant, at least to my eyes.
On this setting I can at least distinguish 1.2% white vs 0% and 98,8% white vs 100%, albeit 1.2% is pretty hard to make out.Gamma Mode:
Gamma mode 3 seems to produce the most linear response out of the lot. The default mode of Gamma 1 strongly emphasizes the midrange values so I'm also suggesting mode 3.3D color settings:
Whenever I enter the 3D mode, the monitor seems to shift the color spectrum heavily towards colder color temps so theres more blue and less red in the image. I tried to make the setting more towards 7000K since the 3D glasses have a slight brownish tint.Response time:
It's been verified in other threads that setting the response time to normal before entering 3D mode leads to less ghosting out of some reason. Since I don't have any issues at normal even in QuakeLive, I'm sticking with it out of pure lazyness. The less buttons I have to push, the happier I am!Final thoughts:
Now this whole stuff definately applies to my SA950 but doesn't neccessarily need to apply to yours! We've already seen measured values on some other review site which produced heavily tinted images on our monitors. Either there are several versions of this monitor around or the reviewer was given some sample that required vastly different settings. Without reference these settings look sort of OK since your brain adapts within few minutes when left without some reference image. I recommend putting some other Monitor, Laptop or whatever next to your main monitor while messing with the settings so you have at least some reference point to compare.
