Correctly adjust the sharpness of your TV: You should note that
With almost all televisions, the image sharpness can be adjusted via the menu. But a high value does not necessarily promise a clear, high-resolution image. The opposite is the case. We show you what you should consider when adjusting the sharpness of your TV.
Image sharpness on TV: Find the right setting
In every television menu you will find the item "Sharpness". Even if it seems logical to set a high or even the maximum value here, this rarely produces a good, sharp image:
- Most televisions focus adjustment is an anti-aliasing tool.
- If the value is raised, the television smoothes outlines in the picture to produce a sharpness effect.
- This can make sense in the case of blurred images, for example in old video cassettes, in the case of high-resolution images such as BlueRays, HD-TV or DVDs, anti-aliasing is superfluous.
- On the contrary: A high sharpness value can cause details in the image to be lost. The anti-aliasing makes the image softer, details such as individual hair or bumps and pores in different materials are captured by the anti-aliasing.
- Another unpleasant effect of anti-aliasing is a bright glow that appears along the outline of people, buildings or objects in the picture.
- Conclusion: Depending on the image source, you should set a lower or higher value for the image sharpness. With high-resolution input images, you should set the value to a minimum.
