Hello mautes,
Thank you for posting in Intel Communities.
Currently, there is no option to adjust the brightness or deactivate the Intel logo on your B580 Limited. There are no methods or applications available to disable the LED logo or modify its brightness on the Intel Arc B580 GPU.
I hope this addresses your concern. If you need further assistance in the future, please feel free to reach out by submitting a new inquiry, as this thread will no longer be monitored.
Sincerely,
JeanetteC.
Intel Customer Support Technician
