The HDMI-port of my iGPU is not working. The CPU is "i5-1235U" and the iGPU is "Alder Lake-UP3 GT2 [Iris Xe Graphics]". Have tried several Linux-distros, its the same everywhere. If i plugin a second display, there is no response. In Windows 11 its fully functional. Reproducible: Always Distro Fedora 38 Workstation Desktop Environment Wayland Compositor mutter Installed Modules: intel-gpu-firmware.noarch 20230804-153.fc38 @updates intel-mediasdk.x86_64 23.2.2-1.fc38 @updates oneVPL-intel-gpu.x86_64 23.1.3-2.fc38 @anaconda xorg-x11-drv-intel.x86_64 2.99.917-55.20210115.fc38 @anaconda

Same thing on Fedora 39 Installed Modules: intel-gpu-firmware.noarch 20231211-1.fc39 @updates intel-mediasdk.x86_64 23.2.2-2.fc39 @anaconda oneVPL-intel-gpu.x86_64 23.3.4-2.fc39 @updates xorg-x11-drv-intel.x86_64 2.99.917-56.20210115.fc39 @anaconda
The Problem is solved in my case by updating the UEFI-Firmware. Now it works like expected :o)
