DVI-D connection does not display properly at higher resolutions (2560 x 1440)
- by Cromulent
I have two computers connected to a Dell U2711 monitor. A PC which is connected using DisplayPort and a Mac connected using DVI-D.
The PC displays 2560 x 1440 resolutions perfectly but when I try and set that resolution on the Mac it displays in an extremely fuzzy manner. So fuzzy in fact that I can hardly read the text on the screen.
I've tried the Mac out connected via DisplayPort (unfortunately the monitor only has one DisplayPort connection) and it worked perfectly. I also had it connected via DVI-D in the past and it worked then. For some reason it just does not work anymore.
I was wondering if this problem might be caused by a dodgy cable or perhaps not having the correct one.
Can anyone think of what the issue might be? I've checked out the DVI-D spec and it should be able to display resolutions of 2560 x 1440 correctly.
