Come controllare un display LG in un MacBook Air e farlo sembrare migliore

Se hai un MacBook Air più recente dovresti prestare attenzione. Alcuni MacBook Airs sono in vendita con display Samsung, alcuni sono in vendita con display LG, entrambi sono display di qualità, ma il profilo colore predefinito di LG è più leggero e un po 'piatto. La maggior parte degli utenti probabilmente non lo noterà, ma se si siede un MacBook Air con un display Samsung accanto a uno con il display LG, è possibile vedere la differenza. Questo è facilmente rimediabile usando un profilo colore personalizzato che ha una gamma migliore. Questo post ti guiderà attraverso come controllare il pannello di produttori che hai e ti mostrerà anche come aggiungere un profilo colore personalizzato che rende il display LG altrettanto bello del Samsung.

Color LCD If the prefix is not “LP” then you have a Samsung display and there's no need to use the color profile or to follow the rest of the instructions, if it does start with LP (like the example shown), then proceed Add a Custom Color Profile for the MacBook Air's LG Display A user on MacRumors forums put together a custom color profile that really sharpens the display of the LG displays in some 2011 MacBook Air machines. Again, if you don't have an LG display then you shouldn't use this profile. Adding this color profile is reversible and you can always go back to the default if you don't like it. Download this .icc profile (or from here on GitHub) to the Desktop Hit Command+Shift+G and enter the following path: /Library/ColorSync/Profiles/Displays/ Copy the downloaded .icc profile to that displays folder, you'll need to authenticate Open “System Preferences” and click on “Displays” Select the “Color” tab and uncheck the box next to “Show profiles for this display only” Click on the second “Color LCD” profile in the list (the top-most Color LCD profile is the default) If you have the LG display, you'll see a difference immediately. Contrasts are sharper, whites are whiter, and there is a much more clear differentiation between minor shades of colors and greys. If you decide you don't like the modified LG profile, just select top-most “Color LCD” in the list. You can also put the color profile into the user home library folder instead of the system library directory, but you'll probably have to make the folder yourself.
