All, I recently bought a Dell U2713H for use with my mbpR-15, and seems like all is fine, but some minor elements missing (colors slightly off..a bit too bright etc.) I am trying to get the Dell to display as close to the mbpR-15 factory setting as possible. I do understand the Retina is much superior, so mirroring is impossible, but still wondering what settings other people using Dell U2713H with their mbpR-15 have used. THIS THREAD IS NOT MEANT TO COMPARE ACD/ATD with DELL, but simply to share the Dell U2713H settings that work best with mbpR-15. So far, what I have done is: 1) Used the miniDP-to-DP cable that came with Dell - works great 2) Copied the Display override file on my mbpR-15 as per: http://embdev.net/topic/284710 3) On the Dell Monitor, I went to Menu->Color Settings->Gamma and set value to MAC (default is PC) 4) Then used the Color Temperature preset mode with value set to 6500K Above settings work well..except the whites are more bright than rich/deep. Would appreciate if users shared their tweaks! Thanks in advance!
