ARC GPU not found in ARC Control Center
ARC GPU not found in ARC Control Center
It seems the ARC GPU isn't showing up in the ARC Control center despite being installed properly. Windows recognizes it, but the task manager lists only the latest drivers from Intel. The monitor connected via ARC is limited to 1080p instead of the intended 1440p, indicating a potential hardware or driver issue. Possible causes include incorrect driver version, driver conflicts, or a faulty connection. I ran DDU again after resetting settings, but the problem resumed once the UHD 630 was installed. Disabling that device and removing the bundled software didn't resolve it.
Checked GPU-Z, confirmed ReBar is active and operating at maximum PCIe 4.0/3.0 bandwidth.
Confirmed, operating at x8 with REBAR included. Updated the report based on recent tests.
It might be wise to confirm whether ReBAR is active in the BIOS settings.
I handled it. It's confirmed.
Edit: For humor, I simply disabled it in the BIOS.
When I downloaded the Intel software for my A380, I visited Intel's site and received the complete driver set. If that didn't resolve the issue, I'd attempt it once more. Note that I never faced problems when all three graphics drivers—Radeon, Nvidia, and Intel—were installed at the same time. I've never needed to use DDU to fix issues across hundreds of configurations I've tested over the years.
I downloaded both UHD 630 and ARC Driver from Intel’s official page. I also experimented with multiple WHQL Driver versions.
I discovered a really silly and bad data point: restart in safe mode. Full DDU Everything. Restart PC while keeping the network active. Don’t install anything manually—just let Windows handle everything. Both installations completed successfully, everything functioned properly, including correct monitor resolutions. It all worked fine after reboot. Still odd, but it’s okay. Installing the ARC Driver package caused everything to fail. Does this mean I should skip installing the real driver packages and just rely on Windows? 0.o
The Arc Command Center software is installed, and you've confirmed overclocking works. It seems there might be an issue with your iGPU drivers causing conflicts.
