The optimal filtering is based on an error metric inspired by ally relevant color space. There is evidence that the human vi- psychophysical experiments.

These filters provide the same quality of font display as yellow [4]. The error in the opponent color space is standard anti-aliasing at a point size 25% smaller.

Is Your Monitor Set up Correctly?
Is your monitor set up correctly? There’s more to setting up a new monitor than simply taking it out of the box if you want to enjoy the best image possible. Buying a new monitor can give a new lease of life to a PC, with a bigger and brighter image, sharper text and more space in which to work. Just plugging it in and switching on won’t always give the best results, however, so it’s worth taking a little time to set it up properly so you can enjoy your new display to the full. These steps all work for laptop screens, too. Step 1: Position it property Where you put your monitor is almost as important as what model you buy. The monitor should be directly in front of you, at an arm’s length away, with the top edge of the screen at eye level when you’re sitting comfortably. You may need to adjust your chair height, or the height of the monitor, to achieve this. Less easy to resolve is where in the room a monitor sits. Ideally, it should be away from any windows to prevent reflections on the screen (a particular problem with glossy coatings) and to avoid bright light behind it. Try not to sit with a window or other source of bright light behind you, for example, or with the monitor in front of one. If you can’t move your desk to prevent this, it is possible to fit a simple shroud around a monitor to prevent reflections, and you can always close a blind or curtain. -
