I print out as much as possible on paper (I know! - tree killer) but I just can't read and make assessments on the 'TV' screen. I need to write notes on just about everything I read and I can't do that without printing it. I'm 45 BTW - old fashioned too - I'm told. Computers can fill a room with data in 2 seconds but someone still has to sift through it all and make conclusions. To answer your original question: I can't look at a monitor for more than 1 hour without eye strain, any type monitor. The headache comes from the data I'm evaluating usually.
