the 1907fp is the best bang for your buck. yes u could always return it. with a dead pixel. the 1907fp is the top rated 19 inch monitor.

Both the E176 and E196 only have VGA or analog connectors, not DVI, or called Digital for the better video cards with digital connetors, just to let you know.  The 1907FP is much better, but its up to you.  Remember, that monitor you finally select will be with you a long time and getting the better one, gives you some future proofing with both analog and digital connections over the other two you mentioned.   You can wait for a Dell promotion or coupon to lower the cost of a better monitor if you have some patients
