Apple iMac 2020 may experience display issues due to AMD Radeon Pro 5700 XT graphics card
According to 9to5mac, some 2020 iMac users have encountered some display problems: A recent article published on the Apple Support Forum stated that AMD Radeon Pro 5700 XT may cause occasional lines on the iMac screen.
Naijatechnews learned that the latest 27-inch iMac can be equipped with Radeon Pro 5700 XT and 16GB GDDR6 memory. This is the most high-end configuration provided by Apple, but it seems to cause users to experience display problems . Some users said that some lines occasionally appeared on the display of their 2020 iMac. The users initially thought that this might be caused by intensive work and high heat, but further tests showed that this was not the case:
I just received a new iMac and noticed lines appearing on the screen from time to time. This is completely random. At first I thought it had something to do with workload/heat, but sometimes even when the computer was idle, I would see some lines on the screen. I ran various benchmark tests for the CPU/GPU and found that the iMac is running normally.
A user added that after further research, the possible cause of this problem is the 5700 XT GPU it carries . However, the overall performance of the iMac does not appear to be affected by this issue.
The same problem with my iMac 2020 has appeared during the initial Mac setup process, and there have been random related problems since then. I found this seems to be a common problem of 5700XT GPU on the Internet or after searching.
It is not yet clear how widespread this issue is. The issue only affects the highest-end GPU configurations of iMacs, which means that this issue may only affect a small number of iMac users. In an ideal situation, Apple will quickly roll out a fix.
Foreign media analysis said that this may be some kind of software problem, related to the driver required by Radeon Pro 5700 XT.
