I have a 24" white iMac and am very happy with its matte LCD screen. I want to buy a new Mac Mini and purchase an external 17" or 20" that is either identical or very similar to the screen of the white iMacs. I don't like glossy or LED screens. I don't need anything fancy, just a monitor that won't cause eyestrain and have a lot of reflections. I would appreciate any product suggestions. Thanks.
