Hello,

I bought a portable monitor: Asus ZenScreen MB166C that has dp alt mode enabled. It should be plug and play with my AMD Ryzen 7 Microsoft Surface laptop 4 but there is no screen projection. The monitor does receive power from the laptop but no video signal through the Asus provided usb-c cable. I'm starting to wonder, is my usb-c connector in my laptop dp alt mode enabled? And if so, to what version?

I did not expect this result from laptop. It's up to date, runs on W11. Anybody an idea if the Surface laptop 4 has dp al mode and how I might fix this? On other hardware devices my usb-c connector responds correctly (exempt dp alt mode so far).

Best regards,

Maarten

    Eventually I started looking for screens within a respectable price range. I ended up with a brand called Arzopa. Their screens have an ok price / quality range. The screen glas is kinda fragile tho, I dropped one on my floor (wooden floor) and sadly the glass got cracked.

    Besides that I have positive on the performance. The only thing that worries me, is the fact that my AV called out a phishing webpage while I was searching through their platform for a new screen ( I searched the US page while I live in EU). The URL got blocked and present to me so I could query it in virus total. 12 other vendors flagged as a phishing URL.

    That's weird right?

    I found out that there different versions of display port alt mode. The screen I bought was not compatible with my surface laptop 4. The versions of display port alt mode did not match. I also found out that it was not something I could have known from the beginning.

    I switched to another brand portable screen, that worked as intended. Maybe a gamble at that point, but I knew that I had to do something.

    I have the same exact issue as original post using the same exact ASUS monitor and laptop model. The ASUS monitor works just fine on my Lenovo Yoga with USB-C lightning port so it's not a monitor issue. I've spoken wit ASUS T2 support-they said since the monitor is a plug and play there are no drivers to download. I tried all of their recommendations to include using a different cable, but that did not work either. There seems to be an issue with the Surface 4 and its ability to recognize the ASUS monitor.

    Does Microsoft offer any other suggestion i.e. newer driver software or something else??

    Thank you!
