Сalibrating a projector requires an accurate understanding of the end result practical and theoretical dexterity. Make custom settings in order to get the clearest picture.
What is projector calibration and why do you need to calibrate a projector.
Everybody would agree that the home theater system’s picture quality is crucial. So when buying a new projector people face with the issue of how to calibrate projector. It is essential to immediately exclude the possibility of a technical malfunction and incorrect operation of the device. And also correctly adjust the color rendition and focal length. Even if you have one of the best projectors it doesn’t ensure you’ll make the best out of it without calibrating. Contrast and brightness, color, and sharpness are the settings that are to meet an individual’s tastes. And the next time you’re watching any video your struggle will be rewarded with high-quality image. The difficulty is that the calibration operates with about 20 image parameters, or rather with their estimates. Adjustment of some parameters of projector calibration affects others – previously configured, and the process itself resembles iterations, each of which brings you closer to the goal. At least it should. An inept game is like a quest, where an inexperienced player must go back from the fifth to the second level and start almost over again. On the contrary, an experienced calibrator is like a puppeteer, gently pulling dozens of threads. He knows what can be done and in what order, and what cannot – so as not to tighten the ball into the Gordian knot. Calibrating projector to create the best picture performance might seem as a hard work – you know that feeling when opening menu on TV – but it’s worthy. Us projector is one of the best projectors after a few minutes calibration whether you’re watching a sport game, movie or concert. This type of modifying is actually very important because it requires different settings for each type of streaming. Want to know how to do that? Here’s how to establish your projector for the natural-looking picture!
What are the parameters and how to calibrate a projector using them
In projector color calibration section parameters are already calibrated for specific patterns which might be named as ‘sports’, ‘game’, ‘user’ etc. You can use them as a foundation for further calibrations. When tuning up and down the measurements you’ll work on:
- Chroma or saturation
Calibrating the brightness
To begin with, there are some industry standards and they are concentrated on providing an average picture. While working on brightness you have to understand that the brightness level of a projector is the level of black it outputs. In order to adjust this level, make sure the black color in the image is black, and not some dark blue. Then bring your projector’s brightness level to maximum. You should notice that the image looks like “burned out”. Then slowly decrease the brightness level until the black color turns from gray to really black. After the moment when black has turned black, concentrate your attention on the small details of the black element of the scene. As you continue to decrease the brightness, make sure that the lapel and folds of the tuxedo remain visible. If the black details have disappeared, add a little brightness, and pay attention to the fact that the black color should be black and at the same time small details of black objects in the image should not disappear.
Calibrating the contrast
The contrast of your projector is the white level. As you did with the brightness, set the contrast level to the maximum level. In doing so, you will notice that light elements of the image will become exclusively white, in some places even objects will glow. Next, as with brightness, gradually reduce the contrast level until you can see fine details of white objects in the image. After you’ve finished adjusting the contrast level, it’s a good idea to go back to adjusting the projector’s brightness, as changing one of the adjustable parameters may affect the other. You may need to go back and forth several times.
Calibrating the saturation
This parameter while calibrating projector is one of those that, if incorrectly adjusted, significantly affect the image and become very noticeable. First, set the maximum and minimum color values (Color) and note for yourself what changes the most in the image. When the chroma value is set to the minimum, the image becomes black and white, when the value at the maximum, the image becomes reddish. In order to adjust this parameter, we need a scene with natural, saturated colors. Pay attention to the faces of the people who are talking and adjust the color level so that the colors of their faces are as natural as possible (no pale cheeks, no red foreheads), while at the same time do not lose sight of other objects in the image, such as green bushes and grass, they are also should look natural.
Calibrating the hue
We will adjust this parameter using the same scene that we used when adjusting the color. As before, set the Tint values to maximum and minimum and notice the changes. At the maximum value, the image turns green, and at the minimum value, it turns red. As with the previous setting on how to calibrate a projector, your goal is to achieve the most natural colors in your image. Try experimenting with the mid-range hue setting without going too far to the extreme.
As in the last examples, look at the image from two sides: with the maximum value for clarity, and with the minimum. At the maximum level of sharpness (Sharpness), the boundaries of objects in the image will be very sharp and possibly slightly deformed, and at minimum values they can merge with the background and other objects in the image. Our task in this case is to set such a value of clarity so that the boundaries of objects are moderately smoothed and do not merge with the background and other objects.
Projector color calibration as a mean of making the best picture
This kind of work is always done by eye. The result is only the personal preference of the individual. Sometimes, the performance obtained during tuning may not match the standardized reference values specified by the manufacturer. However, this does not mean at all that they will not work for you and you should change something. Start only from your own comfort. To get the best picture on your projector all you need is:
- To choose a picture that will serve as a reference for us. It is preferable to choose an image in both light and dark colors, which will contain medium-sized textures and small details;
- To reset the values of all parameters to the factory state;
- To select the values of the characteristics, until the image on the screen matches the reference one;
- To carry out the brightness adjustment;
- To save the values when we achieve the desired result.
And the last question that you may have is how much the image quality on a TV or video projector will improve after calibration. It all depends on the extent to which the device settings were not optimal before the specialist made the necessary adjustments. For example, if after the purchase you set up the panels correctly on your own, then the difference may not be very big – however, you will still be reassured by the fact that now the TV’s potential is being fully realized. If you looked at the panels with factory settings, then the difference in picture quality after calibration will be more significant. It is even possible that the image will seem less attractive to you, less bright and saturated, and the white color will have a pinkish tint. Setting up the projector in this way is perhaps the only way to help make the shots more realistic, fill the images with depth. When calibrating only your own projector, it will be unprofitable to purchase specialized equipment. Based on this, in order to save money and time, it is strongly recommended that you try to calibrate the projector yourself, using improvised means, using one of the methods suggested in this article. Remember, good calibration will always be pleasing to the eye and provide the user with maximum comfort.
