Operating Instructions
Performance Modes
The M7 Ultra features an updated UEFI (BIOS) with three selectable performance modes to optimize power consumption and performance:
- Quiet Mode (35W): Ideal for light tasks and silent operation. Fan noise is reduced to approximately 35dB.
- Balance Mode (50W): A balanced setting for everyday computing, offering a good mix of performance and thermal management.
- Performance Mode (65W-70W): Maximizes CPU and GPU performance for demanding applications and gaming.
These modes can be configured within the UEFI (BIOS) settings. Refer to the UEFI section of this manual for access instructions.
Display Configuration
The Mini PC supports up to four independent displays simultaneously. Connect your displays to the available ports:
- 1x HDMI 2.1 (up to 8K@60Hz)
- 1x DisplayPort 2.0 (up to 8K@60Hz)
- 2x USB4 (Type-C) (up to 4K@144Hz each)
