I am running a Dell S2209W on my 13" Macbook uBody, a pro without FW if you will. Anyway, not sure exactly what is bothering me but after a while, my eyes feel strained. I have calibrated it using the SL built in calibrator and while it is better than out of the box, I still feel eye strain. Anyone else using this monitor and are you happy? Any tricks to calibration levels? Or is this an issue with SL color levels, gamut, etc.? I am seriously considering going to the U2410 for height and tilt capability if nothing else.
