TVs have a wide range of settings, using which you can achieve higher image quality. Correctly adjusting the parameters of the picture, you can get what will be pleasant specifically for your eye. Among the huge number of parameters, there is a sharpness that does not coincide with the resolution. This is why many people have a question: What is TV Sharpness?
Sharpness has the same definition of TVs of various brands, including LG, Samsung, Panasonic, and Sony. The only things that may differ on these TVs are a small software and hardware differences. But the general meaning of Sharpness remains the same for all of them.
What Is the Difference Between Sharpness and Resolution?
If you are not familiar with what sharpness really is, then you may not perceive it as what it really is. A common perception of sharpness is that this parameter changes the resolution of the image.
Purely from a technical point of view, this cannot be true. Modern TVs have a fixed number of pixels, that is, resolution. Even if the original resolution was lower or higher, the TV scales the picture to its resolution.
In fact, sharpness is largely a psychological ploy. By adjusting the sharpness, you change the contrast of the edges. The contrast of the edges, in turn, creates the feeling that the image has become clearer. That is, the viewer perceives the picture more detailed and clear, although its resolution does not change in any way.
Why Shouldn’t Overused Sharpness?
Sharpness seems like a great way to increase image clarity, but if you overuse this option, it turns out that excessive use of this option can lead to negative consequences. Excessive use of sharpness can cause ghosting around the image. Especially, such a negative effect is enhanced if the image was initially grainy. This happens because sharpening makes the edges of the image clearer.
Also, the image will have rougher edges, which will make your eyes get tired from viewing faster. If you abuse sharpness, this will make the image grainy and highlight individual pixels. At the same time, background objects will become more distracting, and individuals will lose their naturalness.
Why Does Sharpness Help Make Your Image Better?
Sharpness can have a positive effect on the perception of a picture if used wisely and not overdo it. If your image has a lower resolution than the TV, then a slight increase in sharpness allows you to detail the picture and get a better viewing experience.
