Can I up­grade my iMac 27-inch Late 2014 for HEVC?

The only iMacs with hard­ware ac­cel­er­a­tion for HEVC are 5K 27-inch Late 2015 with Sky­lake chipsets, and all 2017 mod­els with Kaby Lake. Be­cause this de­pends on the chipset, there won’t be any way to ex­tend sup­port to ear­lier mod­els.

My iMac is life­less!

En­sure it’s get­ting power by us­ing a dif­fer­ent socket and mains ca­ble. Re­set its SMC by dis­con­nect­ing all ca­bles, in­clud­ing power, for 15 se­conds, then re­con­nect and wait for five se­conds be­fore press­ing the Power but­ton. Still no signs of life? It needs re­pair.
