Onboard Graphics

* Because of the limited I/O resources of the PC architecture, the number of Thunderbolt™ devices that can be used is dependent on the number of the PCI Express devices being installed. (Refer to Chapter 2-6, "Back Panel Connectors," for more information.)
* Support for DisplayPort 2.1 version and HDCP 2.3

* Support for HDMI 1.4 version.

Audio

* The front panel line out jack supports DSD audio.

* You can change the functionality of an audio jack using the audio software. To configure 5.1-channel audio, access the audio software for audio settings.

LAN

Marvell® AQtion AQC113C 10GbE LAN chip
(10 Gbps/5 Gbps/2.5 Gbps/1 Gbps/100 Mbps)

Wireless Communication module

* Wi-Fi 7 features require Windows 11 SV3 to function properly. (There is no support driver for Windows 10.)

** Wi-Fi 7 channels on 6 GHz band availability depends on individual country's regulations.

Expansion Slots

* The PCIEX16 slot can only support a graphics card or an NVMe SSD. If only one graphics card is to be installed, be sure to install it in the PCIEX16 slot.
* The PCIEX16 slot shares bandwidth with the M2D_CPU connector. The PCIEX16 slot operates at up to x8 mode when a device is installed in the M2D_CPU connector.
