The hidden menu of LG televisions

LG OLED TVs have long been one of the clear references in terms of picture quality. They may be somewhat more expensive than other options on the market with IPS LED technology, but the truth is that if you are demanding with image quality, they are practically one of the best options along with proposals from other brands with the same technology. Without forgetting of course the good work that Samsung is also doing with QLED technology. Both Korean companies are at the forefront when it comes to next-generation panel technologies, and as a result of this confrontation, users benefit from better and better televisions every year.

For this reason, in addition to demanding users, there are a large number of image professionals (especially video editors) who have bet on them as reference monitors. That is, screens that they will use to carry out color correction tasks in video editing. Why use a TV as a monitor in a professional studio? By price. LG's OLED TVs aren't exactly cheap, but reference monitors are even more prohibitively priced. Considering the quality of LG's OLED panels, it's not surprising that many colorists use these screens for work. After all, LG screens measure up in this regard and can mean great savings for these professionals.

For example, one of the most popular reference monitors is the one from Sony and that one costs around 30.000 euros. So, either you are a large production company that works for important clients that demand the highest possible precision or you have to look for alternatives that are within the reach of your budget and whose investment you can recover. In this sense, LG OLED televisions comply very well.

On which models can you access this professional panel?

We first met this trick with the LG CX TV. However, these professional functions have been maintained in the following generations of this same family of televisions from the Korean manufacturer.

We can confirm that this same process works on TVs. LG OLED C1 and LG OLED C2. In the Gallery range (LG G1 and LG G2 models with LG OLED evo panel), there is hardly any information on the Internet about whether or not this feature can be activated, but considering that they share a platform, it is most likely that all this will work fine. the same way. However, what is confirmed is that the way to access the menu and the secret code has been maintained throughout this time. If you have an LG OLED G1 or LG OLED G2 TV, we recommend that you follow the same steps as described above. And, if you manage to unlock the panel, we would appreciate it if you leave it in comments to help other users.

Configurable parameters of the hidden menu of LG Smart TVs

Once inside this menu you will see that there are a series of advanced settings. These force certain behaviors on the part of the television that can improve the quality or directly ruin it. Hence, it is a hidden menu and only for those users who are clear about what they modify or what the function of each of them is.

These parameters are:

• colorimetry: Refers to the color space to use, for example REC.709 or BT2020.
• EOTF: stands for Electro Optical Transfer Function. It is a parameter that controls the dynamic range of the panel, and it controls one of the fundamental aspects of any screen, which is the gamma.
• Mastering Peak: Affects sharpness. It's basically a micro-contrast adjustment that allows you to simulate the image being sharper. At a very low value, the image will appear very smooth with almost no hard edges. However, at very high settings, 'artifacts' tend to come out, and you will start to notice a very unrealistic image.
• Color Mastering: Reference to the color and calibration of the screen.
• Max CLL: This parameter describes the brightest value that will be reached by the brightest pixel in the panel in any image. By default it is set to automatic, but you can adjust a value on your own.
• MaxFALL: this other one, on the contrary, is the maximum value of the average luminosity of all the photographs that make up the content that is being reproduced.

Complicated? The truth is that yes, a little. luckily there is a Reset button that It allows you to return to the starting point if you see that you are making a mess.

How does each of these parameters affect the final image on the television?

At the end of the post we are going to talk to you about how a professional colorist can take advantage of this hidden panel on LG OLED televisions. If you are a less advanced user, there is a video on YouTube uploaded by HDTVTest which explains very well at a visual level how colorimetry changes affect the television. That way, you can take a look at it and decide before you touch anything whether or not it's worth touching this hidden setting on your panel.

In this case, they use an LG OLED CX to show the color differences between BT.2020, P3 P65 and other settings such as automatic. In any case, the youtuber concludes that for the majority of standard users, the automatic adjustment is the most correct that can be used in this model. The video also shows how you can cancel the HDMI signaling from the secret menu itself.

How to calibrate an LG CX OLED TV for colorist tasks

As we say, this menu is not intended for the normal user. That is, they are options that you have to know well how they affect the video signal that the television is receiving. If this is not the case, beyond a direct benefit it could become the opposite: a detriment. That is why you should only access it if you know what you are going to play and if, for example, you are a colorist.

In this video they explain (in English) how to calibrate the LG CX OLED for color correction tasks. A fairly detailed step-by-step with values ​​that they have verified first-hand that offers the best quality when it comes to showing images with which they are going to work to achieve the most accurate work possible for their broadcast through platforms. like netflix etc

Which also explains why it is not usually an easy screen to find on the market and when an offer appears at specific times such as Black Friday, Prime Day, etc., they tend to fly quickly.

And that the Korean manufacturer It is not the only one that integrates these options. Panasonic is another of those that also includes this mode in its current high-end OLED range, but it is only present for professional users who reach a use agreement with the manufacturer. For the same reason, because if you don't know how each option affects it, it's counterproductive.

In the same way, the important thing is that you know that if you have an OLED television like the LG OLED CX model, you will be able to access this hidden menu, ideal for colourists. And if you don't want to complicate, use the Filmmaker mode which is already, together with a couple of calibration adjustments if you see fit, the best way to enjoy great quality without complications.
