Does anyone know the terminal command to check screen type on rMBP 13?

Hi guys

Wondering if anyone knows the command to check screen manufacturer for the rMPB 13"?

I can find the command for the 15" rMBP but it does not work with my 13".

 

[brop52]

ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6

That doesn't work?

 

[swindlenz]

ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6

That doesn't work?

Nope. Doesn't work. Doesn't even return anything.

Can't do it in the 13 inch, not supported.

It is curious that the 13 inch MacBook Air does have a code to check the screen, but not the 13 inch rMBP.

That script only works for the 15" MacBook Pro Retina, I learned this through experience.

Peace and blessings,

if I remember correctly, Apple disabled it on 13" rMBP, something to do with people returning perfectly fine LG screens for a Samsung screen.

This sounds a little bogus to me lol. How would they disable it without a software update?

Is there an image retention problem on the 13 in to begin with?

And why would they not disable the r15inch where it seems nearly all the problems are?

you can open color sync utility > Devices > Displays > Color LCD > open Factory Profile > scroll to the bottom > open Apple Display Make and Model information > look at the Manufacturer and Model information

You mean on the 13 inch rMBP?

The 13" was released months later. It has different firmware so it would be possible to do it there.

yes, that will work for the 13 inch rMBP. It will work on any macbook.

Unfortunately the ColorSync utility information is useless for this purpose. Identical codes have been spotted in MacBooks as far back as 2008.

There's no known way to identify the actual panel manufacturer in 13 in Retina MBPs. This has been discussed at length both here and at ASC for months now.
