In order to take full advantage of what our televisions are capable of offering, it may not be sufficient to select the display modes configured at the factory. A minimum calibration must be carried out to adapt the screen to the specific conditions of our room.
But don’t worry, you don’t need to call in a specialist to tune everything down to the millimeter. In general, with the configuration options offered by modern televisions, we can achieve very good results by only touching certain parameters based on calibration models with still images or even models on YouTube video.
For this reason, below we have provided seven simple adjustments you can make on TV to achieve the best results without having to resort to external devices or calling in a professional.
We start from the modes predefined by the television (cinema, sports, games, standard, etc.) which can be used as a basis to finish adjusting the various parameters by hand and it is convenient that we make the settings in each video input. (for example on each HDMI port) and if we want to spin more finely for each type of content that we watch.
In addition, we have to make these changes under the usual viewing conditions. This involves standing at the usual distance we will sit at, with the most frequent angle (s), and with the normal ambient light that the room usually has.
In addition, it is advisable to memorize two different settings, one for daily use in bright light and another for watching TV at night and with low light in the room. For example, when there is a lot of ambient light, we will have to increase the level of LED or OLED light above average to have enough brightness, especially if we install the TV near a window.
Configure TV “enhancement” filters
Noise reducers, dynamic or extended contrast, dynamic management based on ambient light or frame interpolation are some of the options generally available on most modern televisions with the aim of automatically improving the quality of the screen. ‘picture.
However, they do not always succeed, especially in models with less processing capacity in the low ranges, and their application produces colorimetric shifts, color saturation in high light images or in areas of high light. shadow, less detail in grays and dark images. .
The case of image interpolation is special, since its application can undoubtedly improve the regularity of lateral and vertical movements of objects on the screen, but it is not without drawbacks such as what is called ” the soap opera effect “, that feeling that the Image is recorded with a poor quality camera or several times taken as if we were going in time lapse.
Very annoying digital artifacts are also created and deteriorate the quality of the image. For example, they appear as “clouds of pixels” around objects that move rapidly from one part of the screen to another. It is especially visible in scenes that change very quickly with flipping objects and movement from one point to another on also moving backgrounds.
So should we deactivate all these functions? Well, it depends on each specific TV. Ideally, we start the settings by turning them all off and then, if we want, we turn them on bit by bit over several days, one by one to test their effect.
Use the best climber available
This is an important point that often goes unnoticed by many users. Most modern televisions with diagonals greater than 32 inches have 4K resolution, a number of pixels that is not present in Freeview, cable or satellite TV content, DVD players, Blu-ray players. ray, in some consoles, etc. They usually offer resolutions of 720p or 1080p.
In these cases, it is necessary to resize the image so that the video source fits the television, which will be done automatically. However, we don’t always realize that we are choosing the highest quality equipment.
For example, if our TV is a very high end model with an excellent image processor, it will probably get better upscaling quality than a cheap Blu-ray player or cable TV receiver, even if it doesn’t. they support 4K output. In these cases, the ideal is to select a Full HD (1080p) resolution on this external equipment and let the television and its super processor take care of it.
But we can have the opposite case. That is, a good external video source with a powerful upscaling system and a low-end TV. Here we will probably get more quality if we force the player to output the 4K signal directly to the TV.
Adjust the brightness
The brightness level of the TV should not be confused with the lighting level of the LED or OLED panel. Contrary to what it may seem, it is responsible for handling the depth of blacks and details in dark areas.
If we set this value very high, we will see that the image is weak, with colors like washed, whitish, with blacks that will appear gray and with dark colors that are like washed out. If we lower the brightness excessively, we will lose detail in the dark areas, in the shades of gray, and all the strength that technologies such as OLED can provide us.
To adjust it, you have to reproduce some classic patterns in which are represented boxes or bands with different levels of tones and set the brightness control of the television to the minimum so that everything is black. From there, we gradually work our way up until we can correctly differentiate the different boxes, distinguishing all the transitions.
Adjust the contrast
It is the parameter which one could call “opposite” to the luminosity, since it is related to the white level and to the total illumination in the image. If we put it too high, we will have a more impressive, more vibrant image, but in reality we will saturate the highlights and we will lose detail in the whites.
If we set it very low, we will lose strength in the image with poor, unimpressive colors that will show little brightness. How do we adjust it? We put a pattern like the one you have on these lines in which boxes with colors of white tones are displayed and we start to increase the contrast of the TV to the maximum until we see everything very white, without distinguishing the transitions .
From there, we reduce the contrast until we can differentiate the transitions between the different tones.
Adapt the sharpness to our viewing distance
Sharpness is the parameter that controls the maximum detail in the micro-information of our television picture. If we put this control to a very low level, it will give us the impression that it is blurry. If we raise it to the maximum, we will see the details in textures, clothes, faces, letters and outlines of figures, etc. much better. but digital artifacts such as jagged edges, digital looking image will also appear, mosquito noise and compression macroblocks will be highlighted.
To adjust it, you can use a pattern like the one we suggest here with horizontal and vertical lines or text of different sizes and vary the sharpness setting of the TV until you get good details but without the flaws described above. above do not appear.
It is important that we sit at the usual viewing distance to calibrate it, because sharpness is a parameter that we can play with when we change the position of the TV or seats in the room. For example, if you sit very far from the screen, you can raise it a little more to have the feeling of not losing definition and you will not notice the flaws. On the contrary, if we sit very close to the TV, it will be convenient to leave it at the minimum values.
Adjust color saturation
Manually adjusting colors on a new TV is a complicated process because we don’t all perceive them the same or with the same intensity, nor are we able to differentiate shades in the same way. If we leave the colors with little saturation, we will get an image without strength, like washed out and whitish. On the contrary, if we exceed it, we will have a very oversaturated image in which we will lose the color intervals and the chromatic scale.
There are some basic patterns that we can follow, like the one we put on these lines, in which we have to be able to differentiate the colors separately and within each bar the different shades of the boxes. If there are two or more areas where we are not able to identify a color gradient, we will probably have a lot of saturation in that color which we will have to correct from the corresponding TV menu.
Choose the color temperature
The color temperature is a parameter that changes the perception of the color range of the television by diverting it towards yellow or bluish tones. Normally, each brand sets up several modes which they name something like “hot”, “cold”, “hot 1.2”, “cold 1.2”, etc. and we just have to choose the one that gives a temperature as close to 6500 degrees Kelvin.
If the adjustment menu allows us to choose directly numerically between several values, then we select this one of 6500 K and that is it. Otherwise we will probably have to look in the instruction manual what they called this optimal value, look for a neutral value or as a last resort try to do it with the naked eye. To do this, we can change between the different values until the colors do not experience any deviation to yellowish or bluish tones in the whites.
