Lack Sharpness on the LCD Monitor

Understand why there is loss of quality in the image in some monitors when the user changes the display resolution

Doubt the player Marcelo Penna sent by email
“Got a Dell Latitude D810 notebook with 15.4 WUXGA screen, which supposedly gives greater for graphics software. Unfortunately, I realized that using the maximum resolution of 1280 by 1024, the letters and icons of Windows and other programs and sites were too small. To change the resolution to 1024 by 768, the images are printed out, no sharpening and flat. The company claims that it has no solution, as it is a feature of the equipment. You know this problem? ”

PC WORLD: Unlike CRT monitors (tube), in which the size and arrangement of pixels (rows and columns) on the screen can be adjusted dynamically according to the chosen mode, in LCDs the size and position of the pixels are fixed, and the best image quality is obtained in only your native mode, i.e. a screen pixel is occupied by one pixel of the LCD.

When we try to play a 1024 x 768 screen in 1280 by 1024, what happens is that the graphical interface seeks to present the pixels in your correct scale with points available, but if the point chart is, for example, 2.5 times greater than the LCD, this point seeks to correct by means of interpolation (pixel adjustments of half-tone).

This effect is perceived in the text string that appear to be blurry and Unsharp. Technically, this problem has no solution. It is precisely for this reason that many users remain faithful to analog monitors yet.

To work around this problem, check out the tips to Improve your monitor images.
