iMac Late 2013 27 in Graphics issue

[philm001]

Hello all,

I have had a iMac Late 2013 for the last 3 or 4 years and I am seeing a graphics issue. It is very similar to the picture attached to this post.

From what I have been reading online, it appears to either be a graphics card issue or the LCD screen is failing. I am thinking to buy a thunderbolt to HDMI converter to test the graphics card.

But first, I wanted to turn to the community to see what you guys think.

By 'similar' I take it to mean that is not an actual photo of the screen? If it is first suggestion get all those desktop files tucked away in Documents/Downloads or wherever you prefer.

From your screen shot, it appears that Adobe Premier Pro is taxing your GPU big time. It can also be a write to disk issue but I would need to see it in real time. With APP, it can also be not enough RAM. Or any combination of the three.

There are a few ways to address this on your machine but it may be throwing good money after bad. The best is to upgrade to a Mac that runs Premier a lot better. I would need to know a lot more about what you are trying to do to know which iMac Pro that is.
