I four table on my dell 6000 3 hours a day with the regular screen. There is significant overlap but I find it far easier on my eyes.

The WUXGA is terrible, from my limited usage. WAY to much resolution for the screen size, and on an LCD monitor like that you have to run the recomended resolution. If you turn it down it blurs...

The WSXGA at most is what I recomend at most. Some up/down overlap, no side/side overlap, and still comfortable to look at.
