I’ve added a 22 inch 2nd monitor via thunderbolt to DVi cable to my 27 in iMac. I have the resolution set to 1680 x 1050 on the Acer X223W 22 in monitor ( no option for higher available ) and I have the 27 in iMac set to 256 x 1440.
As you can see in the photo the e channel is massive. I used to use this 22 inch monitor with my pc and had much finer resolutions.
Is there any way to get a better resolution on this X223w Acer monitor?
