Check for the correct display/panel part number
I've had the display my 2017 iMac replaced at a shop and according to the receipt the correct part LM270QQ1 (SD)(C1) should have been installed. Unfortunately, it has several issues that make me question this:
- It seemed less bright at first and the display settings menu now showed the image of a generic display instead of the iMac – since the store assured me it's the correct model and I couldn't check, I accepted that
- After about a year the display shows strong image retention, an issue that was common in the previous 2015 iMac
So far I could gather the manufacture date using EDID information which is mid 2015 and confirms my suspicion. Also according to a thread on macrumors, the model found in ColorSync is 0000AE07 which matches the older model and not 0000AE13. I wasn't able to find these numbers anywhere else, so I can't verify if this makes sense.
I'd like to test a new screen to see that it actually is the right model and also have something to show to the store where I had the current one installed:
- Is there anywhere else I can see if it it's the right panel either by model number or an output of what the maximum brightness is?
- Can I connect and check the screen before replacing the old one with an external cable?
Bu iyi bir soru mu?
