my new monitor NEC EA274WMi looks sharp when connected to windows but blurred all font texts once connected to OS X. It's very annoying, I work with user interface, small texts, labels, icons.

I tried all every cables and adaptors: display miniport, DVI-D and HDMI. Same problem.

Other monitors with the same issue have solved forcing RGB mode instead of YCbCr, but this patch haven't worked for me http://embdev.net/topic/284710

Is there someone with the same NEC monitor that have resolved (or haven't) this issue?

Thanks in advance for any help.


This is my configuration: Monitor NEC EA274WMi, MacBook Pro Retina, 13 inch, late 2012, Intel HD Graphics 4000 1024 MB, OS X Yosemite 10.10.3

This is a screenshot from my desktop, can you see how blurred is the number 1 in the red square aside the stack exchange logo?



Try disabling LCD font smoothing. Go to the Apple menu, choose System Preferences, then choose General. It's the last checkbox at the very bottom.

Recently I had a similar problem with mail. Reducing transparency under "Accessibility" in System Preferences solved it for me. It seems to be a bug with font rendering.

  • Already tried this too without success, thanks Awado.
