Obviously, there’s more to crisp display than simple dot pitch and resolution would indicate. And even if step back to 1280 x 960 or 1280 x 1024, it’s still fuzzy. Yet if I set it to 1600×1024, it’s fuzzy. My 19″ Optiquest V95 monitor has an image about 13.5″ wide, so it should be able to crisply display 1550 pixels at one per dot. (For more on dot pitch, see Monitor Dot Pitch.) Anything higher than that will be fuzzy, since the monitor will be trying to display more than one pixel per screen dot. That is about 4.5 dots per millimeter or 115 dots per inch. Quite simply, we’re looking at the difference between how many dots per inch the computer is trying to display and how many dots per inch the monitor can show before they start running into each other.Ī decent monitor today will have a horizontal dot pitch of about 0.22 mm. Yet these monitors are often rated for these settings, and often even higher ones. I have yet to see a 15″ CRT monitor that looks crisp at 1024 x 768, or even a 19″ one that does justice to 1280 x 960 or 1280 x 1024 resolution.
