If you can get a chance, you might want to head for a local CompUSA store. There, you can look at the Sony E400 or G400. Both have the 'FD' tubes similar to the KDS AV-195TF. CompUSA usually has these monitors connected to dedicated PCs -- and you can usually adjust the resolution and video settings. You would be able to get some idea on how the text would appear on the KDS.
Like the others have indicated, the shadow mask tubes usually produce the clearest text. I am quite picky in this area and the Samsung 900P has been a great monitor in this regard.
