I keep getting these colored squares on my 27" iMac Display (I do have a second display connected as well). Does anyone know how I can fix this issue?

Basically the graphic card (GPU) needs to be replaced by Apple.

I contacted Apple and they told me to take it to a local certified Apple Repair Center.
21.5” 2011 iMac, same issue. See my thread here: https://forums.macrumors.com/threads/2011-imac-odd-graphic-corruption.2080451/
I’m curious is you are using High Sierra, I am still holding out hope it is a bug in the OS, but I think it’s most likely it’s my graphics card failing.

This past weekend I reloaded starting from Snow Leopard and stopped at Mavericks and it started acting up again in Mountain Lion. Definitely the GPU.
