Sorry, yes I have yoused a german Word for AI.
My post should show an alternative solution approach.

@naizena It might still be worth considering a wireless display option if it's important to you. I'm sure wired is a better solution, but if not possible, it's nice to have another option.
I was going to suggest the Microsoft Miracast Adapter V2, which has worked very well for me with several different UT devices.. but it seems the adapter is no longer produced and it's hard to find a used one.

Does anybody know of any other wireless display adapters that work well?

Mine wasn't cheap, $60 CAD (€40), but if using an external display is an important feature to you, it's a shame not to be able to. I get minor latency in display (well under 0.5 seconds), and two-finger scrolling doesn't always work when using the phone screen as a mouse. But with a Bluetooth keyboard and mouse, it's great. And while not every app is well set up for it, on the whole the OS functions very well in desktop mode.
I hope you're able to find a solution.

@Ian Ok. There it was, yes. Thanks. I don't know how to mark this topic as solved...

@naizena I noticed that too! Very nice. 👍🏻

@lduboeuf I'm running 20.04 OTA-5 rc. But the problem arose last winter, when I was on OTA-2. This year (I have three young children and many activities) I didn't want to make the calendar if it wasn't going to be useful. I'll try a couple of events and change the time manually to see what happens...

Hi @naizena

That's good news.
It's probably a combination of USB port, USB cable and maybe software.

Try to keep track of those to better understand what the problem was.

@Lakotaubp That was! Thanks a lot. Nice day.

@naizena If you can the best way at present would be imho to use the installer use the wipe and bootstrap option to get a clean install of just 20.04.
If, as I think you did and try RC you will still keep all your 16.04 apps. Some if which will still work others will not. TELEports does work but you need to install the 20.04 version from the 20.04 version of the OpenStore now on your device. When you go back to 16.04 you may have to do the same again. The process is not the same as changing channels in 16.04 you are in affect changing OS.

@naizena Just need to mark as solved, here is how. 😁
