Hi, I’m Daniel from Rtings.com.
In this video we will do an overview of how to setup and calibrate the LG C7 OLED. All
of the LG OLED TVs of 2017 have the same picture quality and settings so this applies to other
TVs in the range such as the B7 and E7. First, note there are four HDMI inputs on the TV,
3 at the side and 1 at the back. If you use an external sound system ARC capability, then
you should connect the receiver or sound bar to HDMI 2 to direct the sound from the TV
through your speakers. Other than this, the 4 HDMI inputs have the same capabilities so
connect your devices to any of them. If you have an older device with composite outputs
then you can connect it with this supplied adapter to the rear of the TV. Unlike 2016
models, there is no support for a component input.
With an input connected, you may be asked if you want to activate ‘HDMI Ultra HD Deep
Color’. If so, click ‘OK’ and it will adjust the HDMI port of the TV, allowing it
to use maximum bandwidth. If this notification doesn’t appear then it isn’t a problem
– likely the device doesn’t require full bandwidth or the setting is already enabled.
If you’re using the TV as a PC monitor, then the first thing you’ll want to do is
press the ‘inputs’ button on the remote and set the ‘PC’ icon which allows for
chroma 4:4:4 support. For other devices though, this doesn’t make a difference and is merely
cosmetic. Now, we will go into the settings menu and
disable the ‘Energy Saving’ feature. This adapts the picture depending on the ambient
lighting which can be distracting if it doesn’t quite adjust as you prefer. The same is true
of the ‘Eye Comfort Mode’ setting, and results in changes to the color temperature.
Most people are better off disabling these settings and manually adjusting the TV.
Under ‘OLED Panel Settings’ it is possible to manually perform a pixel refresher, which
takes about an hour and tries to remove uniformity issues. There is no harm in running this so
you can run it every couple of months or when you notice issues. A smaller pixel refresh
automatically runs when the TV is turned off after being in use for 4 hours, which helps
to keep the uniformity in check. The ‘Screen Shift’ option orbits the screen
by a few pixels so that small areas of static content spend less time in one place. It should
be enabled to reduce the chances of any burn-in. Now for the picture mode we go into ‘Picture
Mode Settings’. The ‘Game’ picture mode disables some settings to reduce input lag,
and is the best option for gamers. For other uses though, we recommend the ‘Expert’
picture mode as it allows the most customization of settings. Both expert dark room and expert
bright room have the same performance, but different default settings so they are useful
to have multiple presets you can quickly switch between. The ‘Technicolor’ picture mode
for SDR also offers the same performance, with a different set of default settings.
When a source is sending HDR content, the TV will automatically switch to a selection
of HDR picture modes. Select the ‘Technicolor’ picture mode as it disables the most processing.
Set OLED light to maximum for HDR10 content, or 50 for Dolby Vision content. After this,
follow the rest of our SDR picture settings which we’ll go on to now.
For the picture settings we will be using measurements we’ve taken from our C7 to
show how the picture quality is affected in ways that cameras can’t quite capture accurately.
OLED light adjusts the overall light level of the screen. We’ve measured the white
level of our checkerboard pattern so you can see how the brightness is affected. You should
adjust this to suit your room, without any negative impacts on the picture quality. It
may increase the rate of panel degradation though, especially when set to max.
The contrast setting affects the brightness range of the display. This should be set as
high as possible without clipping highlights and losing details in dark scenes. We’ve
found 95 to be a good value. The ‘Brightness’ option affects the black
level. A value of 50 is almost always the best value. If you reduce the brightness you
will lose details in dark areas, and as you can see increasing it too far past 50 results
in gray blacks. Depending on your picture mode, there may
be a single sharpness setting, or independent horizontal and vertical sharpness settings.
For high quality content, set this to 0 but if you do like a sharper image and don’t
mind some artifacts such as ringing around edges then you can increase this.
The color setting affects the saturation of colors. These measurements are shown on a
CIE XY diagram. Squares on the diagram show target points – what a calibrated display
should achieve with a given input. The circles show measurements from our TV. If the goal
is to produce the same image that the content creator intended, then the measurement circle
should align with the target square. The default value of 50 color is the most accurate, but
you can increase this slightly if you prefer a more vivid look. You can see the measurement
points expanding to the more saturated outer edge of the color space.
Tint has the effect of rotating the color palette. You should almost always leave it
on the default setting of 0 but can see the affect it has on colors in the CIE diagram.
In the ‘Expect Controls’ are some more processing options such as ‘Dynamic Contrast’.
We can see the affect it has by measuring the gamma curve which shows the relationship
between the input signal and brightness. A lower gamma curve results in brighter dark
scenes. A curve with higher values results in deeper dark scenes, but may result in lost
detail in a brighter room. Most movies target a flat gamma of 2.2 which is also what we
aim for in our calibration. The ‘Dynamic Contrast’ setting behaves a bit differently
with HDR and SDR content. In SDR it lowers the gamma curve as shown. Adjustments to the
gamma are usually better done with the ‘Gamma’ setting which we will go over later. In HDR
the setting of ‘Low’ enables the ‘Active HDR’ feature. This may be useful if the
content metadata causes issues but will generally result in a slightly less accurate image.
The ‘Medium’ and ‘High’ options apply dynamic contrast.
Super resolution is a feature which tries to increase the detail of low quality content.
It may be useful for DVDs or cable, but for high quality content leave it disabled to
see the picture as the director intended. The color gamut setting adjusts the tone mapping
of the display to create a more vivid image. You can see the saturation of colors increase
when set to ‘Wide’ or ‘Extended’, but for the most accurate image leave it at
‘Auto’. The ‘Edge Enhancer’ setting also tries
to increase the sharpness of the image, but is more subtle than the ‘Sharpness’ slider.
Unintuitively, it is actually disabled when set to the ‘On’ setting, so leave it onin
HDR for the closest picture to the source material.
The gamma setting adjusts the relationship between shades of dark and bright objects.
Reduce the gamma to 1.9 to bring out more details in a brighter room, or increase it
for a deeper picture in a dark room. Movies are intended to be displayed with a gamma
of 2.2, so we use this for the most accurate image.
In the ‘White Balance’ settings you can adjust the color temperature. For a more vivid
appearance you can use a cooler color temperature which results in all the colors shifting slightly
towards blue as shown in the diagram. For the most accurate image choose ‘Warm 2’
as it is closest to the 6500K color temperature films are mastered at.
The other white balance settings are for fine adjustment of the calibration using specialized
equipment. We post our white balance settings for reference on the website, but the best
settings vary on a unit by unit basis, so we don’t recommend copying them.
Under the ‘Picture Options’ menu are two more noise reduction features. The first option
is for noise usually found in analog signals. The second option is for digital block noise
or compression artifacts. Both of these settings may decrease the sharpness of the image slightly,
but are useful for low quality content such as DVDs or cable.
The black level option adjusts the video range and should be matched to your source player.
Most use limited range video, which corresponds to a ‘Black Level’ setting of ‘Low’.
If your device uses full-range or RGB color such as for PC use then it should be set to
‘High’. A mismatch here will result in crushed blacks and clipped highlights, or
a raised black level and loss of contrast. ‘Real Cinema’ is used to display movies
and other 24p content at the correct cadence. You can usually leave this enabled and it
won’t cause any issues. You can learn more about this from our motion series, linked
in the description below. ‘Motion Eye Care’ adjusts the brightness
of the image depending on the content, however we don’t recommend this to stay true to
the original content. The ‘TruMotion’ option is for motion interpolation,
which is also called the soap opera effect. It is used to interpolate intermediate frames.
You can see more about this feature by viewing our video linked in the description. While
this does introduce artifacts, some people do prefer it, especially on OLED TVs as it
reduces stutter on low frame rate content. Each setting has different presets for the
‘De-judder’ and ‘De-blur’ sliders, but for the most customization you can use
the ‘User’ option and adjust the sliders manually. If you do want to increase the frame
rate of movies without too much soap opera effect we usually recommend setting ‘De-Judder’
to 2, and leaving ‘De-Blur’ on 0. So that’s it. You can find the screenshots
of all the settings we recommend on our website via the link below. And if you like this video,
