Surface Pro 11 + Surface Dock 2: External monitors randomly fail to wake / no HDMI signal

Surface Pro 11 + Surface Dock 2: External monitors randomly fail to wake / no HDMI signal

Christian Kroll 0

I am using a Surface Pro 11 with a Surface Dock 2 (Model 1917) and two MSI PRO MP251LDE E2 monitors.

Setup:

Surface Pro 11, Windows 11
Surface Dock 2, latest firmware
2 × MSI PRO MP251LDE E2, 1920 × 1080
Both monitors connected to the two rear USB-C display outputs of the Dock
2 × identical UGREEN USB-C to HDMI cables, rated for 4K/60 Hz and 1440p/120 Hz

Problem: The external monitors do not wake reliably after boot, shutdown/restart or sleep/wake. The behavior is random: sometimes only the left monitor works, sometimes only the right one, sometimes both, sometimes neither. The monitors then show “HDMI No Signal”, although Windows often still detects both displays in Settings → System → Display.

Unplugging and reconnecting the Surface Connect cable often causes both monitors to start working immediately. Changing the refresh rate between 60 Hz and 120 Hz can also sometimes trigger the displays, but not reliably.

What I already tested:

MSI Auto Scan enabled on both monitors
1920 × 1080 at both 60 Hz and 120 Hz
Extend and Duplicate modes
Landscape and Portrait orientations
Complete power reset of the Surface Dock 2
Surface Dock 2 firmware is up to date
Cleared the Surface display cache using Microsoft’s “surface dock registry.reg” procedure and reconfigured all displays
No lasting improvement

Important diagnostic result: If I disconnect the Surface Dock 2 completely and connect a monitor directly to the USB-C port of the Surface Pro 11 using the same UGREEN USB-C-to-HDMI cable, the monitor wakes reliably after sleep. The issue mainly appears when the monitors are connected through the Surface Dock 2.

This makes me suspect a Surface Dock 2 / Surface Pro 11 display handshake or wake/link-training problem rather than a defective monitor.

Has anyone experienced the same issue with Surface Pro 11 + Surface Dock 2? Are there known firmware, driver or compatibility issues, or any further troubleshooting steps beyond the display-cache reset and Dock firmware update?I am using a Surface Pro 11 with a Surface Dock 2 (Model 1917) and two MSI PRO MP251LDE E2 monitors.

Answer 1

Surface Dock 2 supports two external displays at up to 4K @ 60 Hz, so the dock is not exceeding its documented display capability with two 1920 × 1080 monitors.

Given the symptoms:

both displays are often still detected by Windows,
reconnecting the Surface Connect cable restores output,
direct USB-C-to-HDMI from the Surface Pro 11 works reliably,
display-cache reset and dock firmware update did not permanently fix it,

the remaining supported troubleshooting path is:

Check Surface system updates again in the Surface app
Open the Surface app → expand Help & support → if updates are available, select Check for updates to open Windows Update and install them.
Power reset both monitors
Unplug each monitor from power, then plug it back in.
Verify monitor input selection
On each MSI monitor, confirm the active input is the HDMI port actually in use. Microsoft also notes that the external display must be set to the current port.
Check the monitor port-version/input behavior
If the monitor has an on-screen setting for port version or input handling, adjust it and retest. Microsoft notes that changing the display’s port-version setting can improve results.
Force Windows to reinitialize graphics when the issue occurs
Press Windows logo key + Ctrl + Shift + B. This resets the graphics driver.
Restart the Surface
If the graphics reset does not help, do a full Restart. If needed, do Shut down and power back on.
Roll back or reinstall the display driver if the problem started after an update
In Device Manager → Display adapters:
- For rollback: right-click the display adapter → Properties → Driver tab → Roll Back Driver.
- If rollback is unavailable: right-click the adapter → Uninstall device → select Attempt to remove the driver for this device → Uninstall → restart if prompted → return to Device Manager → right-click adapter → Update driver → Search automatically for updated driver software.
Disconnect and reconnect the Surface to the dock after updates
Microsoft specifically states that after installing a Surface Dock update, the Surface device must be disconnected from the dock and then reconnected.
Retest at 60 Hz first
Since Surface Dock 2 is documented for dual 4K @ 60 Hz, 1080p @ 60 Hz is the most conservative validation point. Test both monitors at 1920 × 1080, 60 Hz before trying higher refresh rates again.
Avoid using a splitter and keep each monitor on its own dock output
Windows documentation notes that splitters duplicate a signal rather than creating independent displays.

Based on the documented material, there is no listed known Surface Pro 11 + Surface Dock 2-specific firmware or compatibility issue in the provided sources. The strongest supported conclusion is that the dock and monitor combination is within spec, and the next steps are Windows graphics-driver recovery, monitor input/port checks, and full Surface update validation.

Because the issue appears mainly through the dock and already survives cache clearing and firmware update, the most relevant next actions are:

validate all Surface/Windows updates in the Surface app,
test both monitors at 1080p/60 Hz,
use Windows + Ctrl + Shift + B when the monitors show HDMI No Signal,
then roll back or reinstall the display driver if the behavior began after an update.

If the problem continues after those steps, the documented escalation path is to use the Surface app for technical support or file feedback through Feedback Hub.

Hi Christian Kroll,

Based on the troubleshooting you've already completed, your testing provides an important clue: the same monitor and USB-C-to-HDMI cable work reliably when connected directly to the Surface Pro 11, while the issue primarily occurs when the displays are connected through the Surface Dock 2. This suggests the displays themselves are likely functioning normally and points more toward how the dock and displays re-establish the video connection after sleep, restart, or wake events.

A few additional steps that may be worth trying:

1, Test with different USB-C to HDMI adapters/cables

If available, try a different brand of USB-C-to-HDMI adapter or an active video adapter.
This can help determine whether the issue is related to compatibility between the dock, adapter chipset, and monitor.

2, Disable Fast Startup

Open Control Panel > Power Options > Choose what the power buttons do.
Select Change settings that are currently unavailable.
Uncheck Turn on fast startup and restart the device.

3, Check for monitor firmware updates

Visit MSI's support site to see whether firmware updates are available for the monitor model.
Firmware updates can sometimes improve display wake and signal detection behavior.

4, Test one monitor at a time through the dock

Disconnect one display and use the system with a single external monitor for a period of time.
This can help identify whether the behavior is related to dual-display negotiation through the dock.
