Windows 10: DisplayPort daisy chain crashes windows 11 laptop on wake-up

Hi,I have a 1st gen Lenovo X1 Nano laptop Windows 11, Intel Iris Xe video that has 2 Dell U2415 monitors daisy chained over DisplayPort, where the first monitor is connected to the laptop with a USB-C to DisplayPort cable plugable brand, and the second monitor is connected via the DisplayPort output from the first. The setup works fine, but when the laptop goes to sleep and wakes back up, it BSODs. This setup previously worked fine on a HP Spectre x360 running windows 10. I disconnected the second monitor so there's only the laptop screen + 1 external monitor connected with the USB-C to

Surface USB-C to DisplayPort Adapter support MST (daisy chaining)?

I have a Surface Pro 7 with Windows 11 and I want to connect 2 monitors and I need to by a USB-C to DisplayPort adapter.

I would like to know if the original Surface USB-C to DisplayPort Adapter support MST (daisy chaining) to connect with one single DisplayPort cable both monitors and expand my desktop.

Now I have a Dell DA300 adapter, but this doesn't support MST.

Thanks for helping.

 

Daisy-chaining on new PC not working

Hi Kevin, I'm Greg, here to help you with this.

1) Here is how to daisy chain multi-monitors successfully:

2) What kind of switch are you using between the two PC's? It adds the kind of complication that requires more expertise than we have here on multi-monitors which is very rudimentary since that's what 90% of users require.

3) For the connection offering poor resolution you can try these extra steps required for setting different resolution, scaling and refresh rate for multi-monitors:

4) For the very best expertise on this I would ask at the forums with the most multi-monitor experts which is Display Fusion forum here:
Discussions • DisplayFusion by Binary Fortress Software

Display Fusion also makes the best software that does what Windows cannot for multi-monitors, but they don't require it to get all possible solutions in their respected forums.

Feel free to ask back any questions. Based on the results you post back, I will have other suggestions if necessary.

DisplayPort Daisy Chain on Dell Monitor not working

We have a problem where a user has 4 monitors hooked up to their Windows 10 system with an RTX 2070 for graphics. They wanted to reserve the HDMI slot on the card, so I suggested running their 24" Dell monitors by daisy chaining the last two monitors. We enabled DisplayPort 1.2 in the Dell settings (FYI - you need to have a valid video signal to get to the menu to turn this on) and double checked that MST was enabled for the graphics card. After plugging in the daisy chained monitor, the monitor would flicker an image of the desktop for a second and then go black.

Windows 10 registered that the monitor was attached and daisy chained but we couldn't get an image to display. Looking around the web and I found a lot of articles saying Dell monitors are terrible for daisy chaining but beyond not enabling DP 1.2 and MST, nothing else was a solution to our problem. Since there is an image that flickers when you first hook it up, it seems like it is just a driver or display issue. Any thoughts?
