My current setup is a mid 2012 MBP non retina attached to a ATD. Though very convenient I am looking to upgrade the monitor first. I really like the ultrawides but also looking at the 27 4k. Thoughts? I may need to use this monitor for both the MBP and a future PC. Been researching resolutions and all and I can live with the lower then 4k res of the ultrawides as long as it fits on my desk thanks.
