[CS-FSLUG] monitor - blurry image

[Frank Bax]

At work, we replaced some CRT monitors with LCD's at select 
workstations.  I put the CRT's on a shelf.  Yesterday, someone's CRT 
stopped working, so another CRT was taken off the shelf that was exactly 
the same make/model.  Today, user emailed saying image is blurry - I didn't 
check closely when I made the swap and I won't be back to look at it myself 
until Monday.  Can this be a driver issue, or is it always the CRT 
itself?  Other CRT's are different make/model; therefore my other post/question.
