Late 2013 27" iMac display replacement / upgrade
I have a late 2013 A1419 27" iMac and while servicing it the technician damaged the flexible cable that feeds into the display itself. I was looking around for a replacement and for some reason the 5k displays are quite a bit cheaper than the correct (LM270WQ1 SD F2, 661-7885) display. The correct panel seems to cost $500USD to $1000USD, while the 5k (LM270QQ1-SDA2) panel seems to only cost $350-$700USD.
From looking at the pictures the connectors appear compatible but I also know that there was an upgrade in graphics hardware to drive the 5k displays. I would really like to make the best of this situation and upgrade the display.
Is there any chance if I buy the 5k display that it will work on my iMac?
If not, can I change to the LM270QW1(SD)(F1) instead of the (F2)?
They seem to be far more common and if there is any actual difference. I know when the letter changes (i.e. C1) that makes the screens incompatible as they look completely different and have different connectors, but F1 and F2 LOOK the same. The F1 is for the late 2012 models while F2 is for late 2013.
Is this a good question?
