DP handshake/DPMS wake-up issue

aaron16 — Tue, 12 May 2026 14:09:56 GMT

GPU: Intel Arc B580
CPU: AMD Ryzen 7 7700
Motherboard: MSI B650-B
Monitor: Hisense G5 Pro 27 inch 2K 180Hz (Connected via DisplayPort)
OS: Windows 11
Driver Version: 32.0.101.8737

Issue Description:
After the display turns off due to Windows screen timeout (or sleep), moving the mouse/keyboard wakes up the PC (fans spin, system runs), but the monitor remains black with a "No Signal" message.

Workaround used:
The only way to get the display back is to hard reboot the PC or physically unplug and re-plug the DisplayPort cable. This seems to be a DP handshake/DPMS wake-up issue with the new driver.

GPU: Intel Arc B580 (Maxsun Milestone 12G)
CPU: AMD Ryzen 7 7700
Motherboard: MSI PRO B650M-B
Memory: 32GB 16GBx2 DDR5 6000MHz
Power Supply: MSI MAG A650BNL 650W
Storage: Kingston KC3000 1TB M.2 SSD
Monitor: Hisense G5 Pro 27 inch 2K 180Hz via DisplayPort

Hello aaron16,

Thank you for posting your query on the Intel Community Forum.

Please accept my apologies for the frustration caused by this DisplayPort wake-up issue. This appears to be a handshake failure where the GPU fails to re-establish a connection with the monitor after entering a low-power state.

To ensure a stable connection during power transitions, I recommend the following adjustments:

Windows Power Settings: Disabling Link State Power Management keeps the connection between your CPU and GPU fully powered. This prevents "No Signal" errors by ensuring the graphics card never enters a deep sleep state that interferes with the wake-up process. Action: Go to Power Options > Change advanced power settings > PCI Express > Link State Power Management and set it to Off.

BIOS Settings: Disabling ASPM ensures a constant connection between your motherboard and GPU, preventing the "handshake" from dropping. Turning off Fast Boot forces a full hardware initialization, which helps the monitor and graphics card sync correctly upon wake-up. Action: In your BIOS under PCI Subsystem Settings, set ASPM to Disabled and turn Fast Boot to Off.

Diagnostic Bandwidth Test: As a diagnostic step to test the DisplayPort cable’s ability to sync at high speeds during wake-up, please temporarily lower your refresh rate to 144Hz. This helps us determine if the issue is related to the specific timing required for 180Hz signals.

If the issue persist after these changes, please provide an Intel System Support Utility (SSU) report (Network tab should be unchecked. This will allow me to review your specific hardware configuration and investigate further. Please check this link: Intel® System Support Utility for Windows*

Please share the resulting SSU log file with us so that we can review the configuration and investigate further.

Thank you for your time and cooperation. I look forward to your update.

Best regards,

Nikhil

Hello aaron16,

I hope you are doing well.

Thank you for sharing your update, and I truly apologize that the issue still persists. I understand how frustrating this must be for you, especially after trying the previous steps.

After analyzing your logs, I have identified a few critical firmware and driver conflicts. Specifically, your BIOS is one version behind, and there is a conflict between your Intel GPU and the active AMD Integrated Graphics.

Please follow these steps in order to resolve the handshake failure:

1. Update BIOS to latest version: Your current BIOS (A.H0) has known handshake delays with newer PCIe 5.0/4.0 GPUs.

Action: Download version A.I0 (or newer) from the MSI website for the PRO B650M-B. This update improves "System Resume" stability.

2. Perform a "Clean Install" of Driver 32.0.101.8801: Download the latest 8801 driver. Use Display Driver Uninstaller (DDU) in Safe Mode to wipe existing Intel drivers, then install 8801. Please check the link for latest driver:

3. Disable AMD iGPU & GameViewer Hook: The logs show the AMD Integrated Graphics and a "GameViewer" virtual driver are active. These often "hijack" the wake signal before it reaches the Arc B580.

BIOS: Navigate to Settings > Advanced > Integrated Graphics Configuration and set Integrated Graphics to Disabled.
Windows: Uninstall the GameViewer software and any associated virtual display drivers in Device Manager.

4. Adjust Windows Fast Startup:

Action: Go to Control Panel > Power Options > Choose what the power buttons do and uncheck "Turn on fast startup." This forces the driver to re-initialize the DisplayPort link fresh every time the system wakes.

Please try these steps and let me know result. Thank you for your time and cooperation. I look forward to your update.

Best regards,

Nikhil

Hello aaron16,

I hope you are doing well.

Thank you for sharing the details of the issue. I appreciate you outlining the steps and the troubleshooting already performed.

To further investigate this issue, could you please help us with the following details:

- Kindly confirm which PCIe slot the B580 graphics card is installed in?

- Does the issue occur when the system is actively in use (i.e., without screen timeout or power-saving settings enabled) after a system reboot, do you continue to experience the same issue?

These details will help us better isolate the root cause and assist you more effectively.

If you have any additional observations or questions, please feel free to share them we’re here to help.

Thank you for your patience and cooperation.

q1
B580 is installed in the first (and only) PCIe x16 slot on the MSI B650M motherboard (PCIe 4.0). Using DP port on the card.

q2
With system set to never sleep, never hibernate, and never turn off the display — the issue does not occur. Connection is stable.

Hello aaron16,

I hope you are doing well.

Thank you for confirming that your hardware runs perfectly when timeouts are disabled. Based on the behavior observed, I am currently investigating this.

To resolve this on the current driver branch, please apply the following configurations to help ensure a stable connection:

1. Disable Monitor Deep Sleep (OSD Menu):

Modern high-refresh displays often use aggressive power-saving modes that shut down their DisplayPort receivers when no signal is detected, which may cause them to miss the PC's wake command.

Action:

Use the physical buttons on your Hisense monitor to open its built-in menu.
Under Power Settings, set Deep Sleep, Auto Power Down, or Eco Mode to OFF.
Change Input Source from Auto-Detect to Manual (DisplayPort).
This helps keep the monitor’s scaler active and ready to receive the GPU’s wake signal.

2. Purge Stale Windows Display Caches:

Driver updates can sometimes conflict with cached display topology (EDID) stored in Windows, potentially affecting power state synchronization.

Action:

Right-click Start and open Device Manager.
Click View → select Show hidden devices.
Expand Monitors, then right-click and uninstall all translucent/grayed-out monitor entries.
Restart your PC to allow Windows to rebuild the display configuration.

Additionally, could you please confirm if you have tested the system with another GPU? This will help us further isolate whether the behavior is specific to the current graphics hardware or setup.

Please try these steps and let us know the results so we can continue tracking this behavior closely.

Thank you for your time and cooperation. I look forward to your update.

Best regards,

I have tried all the steps mentioned above but the problem still exists.

My monitor Hisense G5 Pro does not have options to disable deep sleep auto power down or eco mode in its OSD. So I cannot try that step.

This issue started in the first half of this year after updating to a newer driver. Last years driver did not have this problem.

I once rolled back to an older driver and the issue was completely gone. After updating again later the problem came back.

I tried to find last years driver on the Intel official website but it is no longer available for download.

All other suggested steps have been tested including disabling PCIe Link State Power Management ASPM Fast Boot Fast Startup AMD iGPU removing stale monitor entries lowering refresh rate and using DDU clean install. None of them resolved the issue.

I only have this Intel Arc B580 GPU so I cannot test with another graphics card.

Please let me know if there is any way to get an older driver from 2025 that worked correctly or if this will be fixed in a future driver update.
