Ghosting on replaced MacBook Pro 15" retina screen (Samsung)

Hi all.

I just replaced my retina display on my Macbook Pro 15" Late 13 (replaced by a technician). The display was purchased on e-bay and was listet as new. After installment the new screen has severe ghosting and leaves a very visual imprint of any graphics displayed on screen. After doing several rounds on Google I´ve found a lot of threads regarding the ghosting problem on LGs retina displays from 2012, including Apples very weak "screen-saver"-fix for the problem. I have contacted the vendor I purchased the new screen from, but they claim that the screen I have received is a Samsung and not an LG. My question then is, could it be possible that the ghosting can be caused by the internal faulty connection? A lose cable or sloppy work by the technician? And - are there any known ghosting issues on the Samsung retina displays?

Cheers,

Colin

Apple has used different signaling systems between the logic board and the LCD panel. The older method was called LVDS currently Apple is using iDP which is a version of DisplayPort interface.

Here's a bit more on LCD persistence: LCD Screen Burn in on a Mac?! How to fix ghosting, stuck pixels: LCD vs AMOLED vs Plasma differences which is likely what you are seeing here vs a moving ghost image which follows the object.

With LVDS a bad or damaged cable would bleed colors or mis-colorize a section of the display. With iDP its more like a digital TV signal which corrupted over the air where you get a ripped image or checkerboard of blocks which are missing. So I don't think thats your issue here.

A poor quality display is more likely the issue where the liquid crystal material (cholesterol) within the panel is bad.

Thank you so much for answering, Dan. The LVDS vs iDP issue was quite ineterresting but the description does not match my issue, unfortunately. However, I really appreciate it as I atleast can eliminate a few suspecions.

The LCM might very well be the problem, however there does not seem to be an easy fix AFAIK.

Cheers!

I've got the same issue on my 2012 MBP w/Retina.

Run this terminal command: ioreg -lw0 | grep "EDID" | sed "/[^<]*</s///" | xxd -p -r

"LP" followed by a bunch of number is LG and "LSN" is Samsung. Supposedly second-gen LG displays are all good now, but who knows. I'm typing this on a friend's machine (same as my ghosting one) and hers has and LG panel with no ghosting (yet). Mine is also an LG panel. Mine ends in SJA1 and hers in SJE1. Maybe she has second rev. Don't know.

Supposedly there have been reports of Samsung ones also having the image retention problem, but the vast majority sound like it's LG (first rev? second rev?).

Hope this helps. Better late than never?
