I just hope the display of the 27 inches iMac 2013 can hold up for three years. Reading this thread https://www.macrumors.com/2013/10/2...action-lawsuit-over-failing-27-imac-displays/ really got me worry about my new iMac. I cannot find a lot of information about image retention or flaws on the 27-inch screen for the iMac 2013. I guess only time will tell.
Read other threads about 27'' iMac LG monitor problems (i.e. IR, light bleeding, yellowish, ghosting etc).
If I want to buy a new iMac, I will prefer the new 21.5'' iMac. There is only a small amount of reported monitor problems...this is also a LG monitor, though!
I think SAMSUNG is more reliable but APPLE decided to sign contract with LG for the 2012-2013 iMac monitors. I heard replacement parts are coming from SAMSUNG....I hope APPLE will replace all the defective monitors under warranty.
calm down LG know about the 2012 panels issue...until now i havent see any
today i've checked the 11'th 27" panel
