Hi, I've just gotten the Mini DisplayPort to DVI Adaptor to pair it with the DELL E228WFP 22inch monitor. Apparently, I can't seem to configure the E228WFP to display the resolution of 1680 x 1050 via Mirror Mode. The only config for the E228WFP to display 1680 x 1050 is to arrange it side by side aka extended display. Called up AppleCare and the technician advised that is because the maximum resolution the Macbook UB 13inch is can go 1280 x 800 and thus, when configured on Mirror Mode, E228WFP will only display 1280 x 800 instead of the native 1680 x 1050. Is there a method (other than extended display configuration) which allows the E228WFP to produce a resolution of 1680 x 1050 when config on mirror mode with the Macbook UB 13inch?
