I got my display last tuesday and haven't had enough time to calibrate it properly. I think I need to write down the first things I found about this monitor and add more later.
But after a couple of days you get used to it and want a wider one :)
A curved panel could work for a monitor this wide.
The contrast ratio is typical for IPS panel, about 1000:1 for both static contrast and ANSI contrast.
I use Colormunki Photo spectrophotometer to get spectral curves and the XYZ correction matrix for i1 Lite colorimeter. For actual measuring and calibration I then use i1 Lite because it works better in low light than spectrophotometer. As a software I use ArgyllCMS, DispcalGui and HCFR.
Green and red are a bit oversaturated and blue is the most accurate.
Green: 45
Blue: 46
Now deltaE in HCFR keeps below 3.
And color temperature is quite accurate.
What is Super Energy Saving feature? You tell me. Or maybe LG should tell us what it is and how it's supposed to work and how it actually works.
LG Manual says:
Super Energy Saving:
High = Saves energy using high-efficient Super Energy Saving feature
Low = Saves energy using low-efficient Super Energy Saving feature
Off = Disables the Super Energy Saving feature
The gamma measurement when the setting is Off and Gamma is Gamma0 which seems to be 2.4, the way I like it.
There are no readings below 20%. Why? Because when Super Energy Saving is Off and you have dark uniform screen for more than 5 seconds, LG completely dims the backlighting. Even when Super Energy Saving is OFF! This is not a feature, this is a bug. A hope they are going to fix this soon. This bug is not in Low and High settings. They do not completely dim the monitor.
If Super Energy Saving is Low or High, there's is some kind of dynamic contrast thing going on but it's working very slow and not recommended for movies. But you can't use the setting Off either because it might dim the screen if you are watching Dark Knight. Wow. What are they thinking?
Because I cannot measure the black when SES if Off and Low and High settings use this slow dynamic contrast.only way to get measurements is setting Latency time for Dynamic Iris in HCFR to 400ms. That seems to be the time it takes for this "energy saver" to adjust to new screen brightness. For a movies or games that 400ms is a awful lot of frames and time.
This is a gamma when Latency Time is 300ms.
This is gamma when Latency Time is 400ms or more or when SES is Off.
This is not a perfect calibration because of the flaws in SES but it's the best I can get.
Easy Control
- Brightness=70
- Contrast=74
Function
- SES=Low
Color
- Gamma=Gamma0
- Red=51
- Green=48
- Blue=54
With these values Red color is just about to be burned and the static contrast is 1034:1 and ANSI contrast 1011:1.
LG claims in it's web site that this monitor has 5M:1 dynamic contrast ratio. How? Do they mean when the monitor shuts the backlighting completely that it counts as dynamic contrast?? Why do they use these ridiculous claims in their marketing?
The Panel
It's wide. If you look it sideways, it resembles the Star Destroyer at the beginning of Star Wars episode IV. It never ends.

The Contrast

The Color Gamut
Green and red are a bit oversaturated and blue is the most accurate.
The RGB levels and color temperature
The default color temperature is accurate but quite high 7000K. With setting Screen/Color/Color Temp/Warm it was still 6650K so I changed the Setting to Custom and new RGB values:
Red: 50Green: 45
Blue: 46
Now deltaE in HCFR keeps below 3.
And color temperature is quite accurate.
The gamma ( and the Super Energy Saver )
One cannot write about gamma and gray scale measuring without the Super Energy Saving feature.
