Hi.
Please see attached picture.
As you can see, white zones appear next to the black text.
What can I do to fix it?
Windows own "Adjust Cleartype text" - Have been tried.
Screen: Samsung SyncMaster B2430

(Maybe it does not look super bad in the picure, but it was hard to catch,, it makes it really hard to read the words often, so please help.
