If you guys know, I used to post my M3 iMac screen suddenly have " Flickering lines " appear at the bottom of the screen upon using just one years or so. Some M series iMac users also claim the same. Whereas some claim they so far never encounter.

Nevertheless I just order M4 iMac and happen come today. So I do all the migration etc. I even check the display settings to see all is it the same between this M4 iMac and M3 iMac.

I notice this M4 iMac , I just received. The screen brightness seem not say " White, bright " than the M3 iMac despite I have check the brightness , night shift, true tone even the colour profiles are all the same. The M4 iMac the screen look warmer side whereas the M3 iMac more whiter. So I go google, it claim


Factory Calibration Tolerances: No two LCD panels leave the factory exactly the same. One may naturally skew slightly warmer (yellower) or cooler (bluer).

I not sure is it due to many M series iMac users complain the flickering lines Suddenly appear upon using just one year or so. Apple change supplier? I do know come iPhone also have the same situation whereby some folks iPhone the screen look whiter than others whose screen is more warmer.
