Connected monitors are not displaying anything when connected togeteher through surface dock 2 - it used to work well and still working when connecting only 1 monitor

Hello Community,

I have two DELL monitors connected via a Surface Dock 2 to a Surface Pro 11th Edition.

Everything worked perfectly initially, but it suddenly stopped. When I connect only one monitor through the dock, it works fine. However, connecting both monitors causes issues.

I have followed all suggested steps below, including disconnecting and reconnecting everything, updating all drivers, and more.

The system recognizes the monitors, but nothing appears on the screens.

Any advice?

Hello,

The troubleshooting steps your link has is very thorough, but it does not mention clearing the display cache for the Surface Dock.https://support.microsoft.com/en-us/surface/troubleshoot-connecting-surface-to-an-external-display-bc8f5121-a4cb-cf0b-5770-2df7a66a3b28

Follow this guide from the official Microsoft support page, I'd like to point out the part which mentions the display cache since that wasn't mentioned in the comment you linked.

I also recommend trying the monitors on different devices and swapping out the cables to figure out if the issue is with the dock, the monitors or the cables.

Let me know how it goes,

JC

Hi JC,

Thanks again for your time and your answer.

I tried clearing the registry cache as suggested, but unfortunately, it didn’t help.

A detail that might be useful:

When I connect either screen to the dock — but only one at a time — the display works perfectly.

If I switch cables, the result is the same: whichever single screen is connected is displayed correctly.

The issue occurs only when both monitors are connected simultaneously, even though this setup worked fine for months with the very same hardware and cables before suddenly stopping about three months ago.

Let me know what you recommend as the next step.

Thanks,
