LCD ghost images, fuzzy fonts and image persistence |
A couple weeks ago my friend Lestat got a new LCD monitor and said he had problems with ghost images. He asked if I had experienced similar problems with the Westinghouse LCD I recently purchased. I did have some LCD ghosting issues, particularly around the Windows shortcuts, but it wasn’t such that it bothered me much. Text seemed to be OK.
Turns out that Lestat did some research and discovered this somewhat common problem was called image persistence and the solution he found was to create a white GIF image and use it as a screensaver.
Last night I was reading Scoble on ClearType (here is the ClearType Web interface) and decided to try that out as well.
First I downloaded the ClearType PowerToy and then ran it. Here are before and after shots of the difference in the readability of the fonts in the PowerToy window when enabled and disabled (note: the images are compressed for the web, so the effect isn’t as sharp as actually seen, but you can still see a difference):
Before ClearType

After ClearType (enabled)

With the tip Lestat offered and ClearType enabled the faint ghost images around the Windows shortcuts on my desktop disappeared. Also, the text on the LCD monitor was noticeably sharper and easier on my eyes.
Thank you Lestat and Robert Scoble!
