Windows 10: Surface to reconnect to USB-C external monitor after turning it off because of idle time

Hi,Surface Pro 9Windows 11 ProExternal Monitor connected directly via USB-C cable Acer and keyboard + mouse monitor USB hubWhen I connect the external monitor, I will close the cover and the set the display to show only on second screen.When the display times out, the screen will go dark and monitor LED will be dimmed. At this point, unless I turn off and then on the monitor, the Surface won't reconnect to the monitor. Even open the cover won't do that.Is there any power management setting would make it reconnect?Thanks

On Windows 11, my external monitor(s) won't wake up after they have been turned off

Hello Moritz Schwarz,

Thank you for posting in Microsoft Community.

I understand that you are experiencing issues with your external monitors connected to your Surface Laptop 5 not waking up after they have been turned off. I am here to help and let us work on this together. Allow me to ask some questions so we can further isolate your issue and formulate appropriate troubleshooting steps.

• Could you please tell me the make and model of the external monitors you used?
  
• Would you mind verifying if you're connecting both monitors with a Surface Dock?
  
• Did this work before?
  
• When did this issue started?
  

For the meantime, kindly try the following steps to troubleshoot this problem and see if problem persist.

1. Make sure that your device is up to date. You may also check optional updates available.
   
2. Update your graphics driver. You can do this by going to the Device Manager, finding your graphics card, right-clicking on it, and selecting "Update driver."
   
3. Try connecting the monitors to a different device to see if the issue persists.
   
4. Try using a different USB-C cable to connect the monitors. Make sure that the USB-C cable supports USB 4.0/Thunderbolt™ 4.
   
5. Try turning on the monitor that you're having issues with by pressing the Windows logo + P for monitor switch options, then set it to "this screen only" then Extended.

I look forward to hearing from you.

Kind regards,

Microsoft Surface Pro 7 usb-c external monitor problems

The MS Surface Pro 7 has a very picky usb-c port, is anybody looking at improving this port.

The computers below work with any of our external monitors, HDMI adapters or cables.

MS Surface Pro 1 mini display port
MS Surface Pro 3 mini display port
HP Spectre Bang Olufsen usb-c port

MS Surface Pro 7 usb-c port - ONLY works with a Moshi 4K/60 HDMI adapter.

I bought the MS Surface Pro 7 in late March 2020.

Only after installing update KB4551762 on March 27th did the external monitor work properly (with the Moshi adapter). I have version 1909 installed.

The MS Surface Pro 7 is now updated to KB4550945

These adapters still DO NOT WORK for the MS Surface Pro 7:

Microsoft usbc to HMDI adapter
Belkin (4K/60hz) usbc to HMDI adapter
Satechi (4K slim multi port) usbc to HMDI adapter

The monitor says Input Signal Not Found.

The external monitor is a new HP Pavillion 27inch Quantum Dot.

The cable spec is 0.5m ESL high speed gaming.

Only for this Moshi 4K/60 HDMI adapter, I would have needed to return the MS Surface Pro 7.

 

Surface Laptop 4 doesn't connect to external displays through USB-C

Hi, I bought a refurbished Surface Laptop 4 with windows 11 2 1/2 weeks ago and I haven't been able to use the USB-C port for any external displays/monitors. I first discovered the problem when trying to connect my Huion Kamvas 16 display tablet, which connects through a USB-C-> USB-C cable that’s compatible with DisplayPort alternate mode. When the tablet is plugged in, my computer registers it as a display but starts freezing intermittently and the screen blinks on and off. I’ve also tried plugging my laptop into different external monitors with an HDMI->USB-C adaptor. With the HDMI-> USB-C, it registers as a USB-C Video Adaptor in my device manager and under “other devices”, but not as a monitor. I can still charge my phone and interface with it through the USB-C port. I don’t have any other devices I can check with it.

Here's the troubleshooting I've done so far:

• Turned my laptop off and on again
  

• Connected both the tablet and other monitors to other devices- both worked perfectly fine as expected, so the issue isn't with the cords or external devices
  
• Kept my display tablet powered through its external charging device. My laptop still freezes intermittently and blinks on and off
  
• Uninstalling and re-installing the USB drivers through device manager
  
• Uninstalling and re-installing the drivers and firmware for my tablet- I double checked the drivers with the serial number to make sure it was the correct ones.
  
• plugging in the tablet without drivers, which should normally just register it as an external monitor. My laptop still freezes intermittently and blinks on and off.
  
• Checked the system requirements and specs for the tablet and my laptop's USB-C port- I didn't find anything that would indicate it's incompatible with the tablet or the HDMI->USB-C adaptor
  
• All options that could be done on the external monitors and usb-c microsoft troubleshooting pages
  
• Note: I restarted my laptop after each uninstallation and re-installation process.
  

Why am I asking for help here instead of with my tablet's manufacturer? Because I'm convinced it's an issue with my USB-C port and not an issue with my tablet. The tablet works fine with other devices (unfortunately I don’t anyone else with a SL4), and my computer just doesn’t connect to any other displays, period. It’s only my USB-C port that’s causing issues.



Short of factory resetting my computer, I can’t think of anything else to try. Is the Surface Laptop 4 just unable to connect to external displays through the USB-C port? I rely on my drawing tablet for supplemental income so if it’s not compatible, I need to know so I can get a new laptop.

Edit: Clarified one of the bullet points further
