XPS 13 9350 Wireless Display

Miracast has never been an especially reliable protocol, but definitely try updating your drivers and TV firmware if you haven't already, and even your BIOS since I remember a BIOS update improving WiFi throughput on a Latitude 7480 once, so perhaps that might make a difference here.  Also note that Miracast uses Wi-Fi Direct, i.e. it connects directly from the laptop to the TV.  It does NOT go through a router, even if the PC and TV are on the same Wi-Fi network, so if you're currently trying to project to the TV while your PC is farther away and are expecting the router to bridge the gap, then that could be the issue as well.

I have the same problem. What i have found out is to disconnect from wifi router/net and then connect to Wireless Display, then it works, but that's not an option just a clue for troubleshooting.

yeah - same model XPS (9350), same problem. Some details that may or may not differ:

• Problem occurs both on an LG smart TV with Miracast as well as another TV that has an attached Microsoft wireless display adapter.
• Problem does NOT occur on the Dell XPS 9365 models (or any other computers) that are in the office.
• Dell SupportAssist scan shows BIOS and all drivers are up-to-date.
• Interestingly, problem does NOT occur if I disconnect the Intel(R) Dual Band Wireless-AC 7265. Of course, as was already pointed out, that's no solution because what we have to project on the TV is internet stuff.

SO...is there any solution on the horizon? Is Dell updating the BIOS or drivers for this model ('cause things work with OTHER XPSs)?

Same problem. I now found out through other replies that it connects if I have no WiFi connection, but as mentioned before, that is not very useful. Dell, please fix this.

Found a fix for this. It was the wifi connection frequency, I was using 5Ghz and miracast uses 2.4Ghz so when I changed the connection on my laptop it worked! Finally! Hope that's helpful for people.

it's 2023 and DELL is still not able to make this work - at least it is not working on Dell XPS 13 (7390); on other Dell eg Precision laptops it will  work, but weren't those XPS supposed to be " premium" products?!
what a (bad) joke
