This monitor has to have the worst case of geometry problems I have ever seen. Sure, the advanced controls will let you square the image perfectly to the bezel, but at the cost of grossly distorting the image. Even when I tried to get a uniform image by letting the sides freely distort, it still didn't help. At my 900NF's best, screen images along the top curve up 1/ 4" and left side images bend to the left enough to be irritating. Other minor imperfections include the lower left corner which is out of focus and miscovergence that abounds throughout the display. Sad thing is that if this monitor had been built with a bit of care it would be a great unit. The controls are advanced enough for most users, and the .25AG display is sharp and crisp...despite the distortion. If you still aren't convinced to buy another model/brand, just make sure a liberal return policy comes with your purchase.
