Great now i see both GPU from the system report.
But second display is not detected, it`s look like that only one display can be attached at the time, event connect on IGPU or EGPU.
In regards to the video i try with the same process for export and now timing is 6min40sec.
EGPU is not loaded on 100%, about 70 80% and CPU is normal as well.
Unfortunately, i dont have good tool to check both GPU utilization, from the system monitor showing EGPU history.
Thanks in advance for your help, tell me if i can do someting for you!
