Hi there,
Please send us a picture of the SN on the bottom of the PC.
Since “up to date” via the Intel tool doesn’t rule out a corrupted install, here is the step-by-step fix, ranked from most likely to resolve it to advanced.
Step 1: Restart the Windows Shell (Quick Test)
Since the cursor works, the shell might just be hung.
Press Ctrl + Shift + Esc to open Task Manager.
Look for Windows Explorer in the list. Right-click it and select Restart.
If the desktop appears, great—but this is temporary. You still need to follow the rest of the steps to fix the underlying driver issue.
Step 2: The “Nuclear” Driver Clean (Crucial Step)
Do not just “Update” the driver. You must completely wipe the old one, as Windows often hides corrupted registry entries that survive standard updates.
Download the latest Intel Arc Graphics Driver (version 31.0.101.xxxx or newer) from Intel’s official website onto your desktop. Do not install it yet.
Download Display Driver Uninstaller (DDU) from Guru3D and extract it.
Disable Wi-Fi/Ethernet (pull the plug) – This prevents Windows Update from auto-installing a generic driver while you work.
Reboot your PC into Safe Mode.
Run DDU, select “GPU” on the right side, choose “Intel,” and click “Clean and Restart.”
Once rebooted (still offline), run the Intel driver installer you downloaded earlier. Install it fresh.
Reconnect your internet.
Step 3: Force the Correct Display Mode (Fixes the DP flicker)
The DP flickering happens because the GPU and monitor are fighting over the “Link Training” speed and Display Stream Compression (DSC).
Right-click the desktop and go to Display Settings > Advanced Display.
Change the Refresh Rate to 60Hz (temporarily). If that stops the flickering, the DP cable you are using is not rated for the high bandwidth of 144Hz/4K. You will need a VESA-certified DP 1.4 or DP 2.0 cable.
While you are here, turn off HDR if it is enabled. Intel Arc drivers have known handshake issues with HDR on specific monitors.
Step 4: Power Management for the DP Port
Windows power-saving can cause the DP port to drop signal repeatedly (the blackouts).
Go to Control Panel > Power Options > Change plan settings > Change advanced power settings.
Expand PCI Express > Link State Power Management. Set it to Off.
Expand Display > Enable adaptive brightness - turn it Off.
Reboot.
If none of the above works, try this final hardware test:
Boot the Beelink into your BIOS screen (Del/F2). Look at the BIOS menu. Does the BIOS screen flicker or show correctly?
If the BIOS screen is also black/flickering, you have a faulty HDMI/DP port on the Beelink motherboard itself—request a replacement.
If the BIOS screen is crystal clear, but Windows is black— the DDU clean install (Step 2) will fix it
