White Horizontal Line on new 2020 iMac with AMD Radeon Pro 5700 XT 16 GB graphics card

I have this issue on 2020 iMac i9 5700 XT NVRAm and SMC reset does not help

I also have this issue with my iMac 27" 2020 with a 5700 XT 16GB graphics card option.

Yep thanks, I’m aware of that. Raising my issue here to make sure Apple starts taking this problem seriously...! 🤦‍♂️

Apple not here! Only users of Apple products, no Apple employees.

Thanks for your video. We have exactly the same problem. I can watch on your video the same white horizontal line it occurs on my new 2020 iMac screen. (Also freshly unboxed).

Thanks for the video, I'm holding off buying a new iMac until this is fixed.

got mine on mid-August , had the issues and graphic crash on some apps. returned and they sent a replacement, the replacement freeze twice and same horizontal lines ( lighting ) decided to returned and not get replacement at the moment, I will wait if there is some fix or apple do something about this, I had bad experience back in time to 2011 graphics issues on 27'' mine failed , got fixed in 2014 by recall program and fail again after 2 years, spend a lot money on this model and no want same experience as 2011 model. for that reason learn, return, wait and buy again when is fixed

Hi(Bonjour)

Look at his video to see my unhappy unboxing...

Look at Youtube...

Mine exhibited this as well. Nothing worked to correct it. I sent it back and my replacement will be here tomorrow. Fingers crossed.
