M1 iPad Pro and the LG Ultrafine 5K - No full screen

I have the updated LG Ultrafine 5K (so with USB-C support) and the M1 iPad Pro 12.9. From what I understood, it should be possible to connect the iPad to the display and get full screen support (as demo’d by Apple). However, whenever I connect my M1 iPad Pro, via the Thunderbolt 3 cable, I keep getting the black bars on the side as was the case with the pre-M1 iPads.



Does someone here have an idea how to enable full screen on the Ultrafine 5K with an M1 iPad Pro?
 
There is no real full-screen support for the iPad. Unless apps support extended display - as most video players do - you will get a mirrored display in 4:3 format and bars. What Apple showed was the app LumaFusion playing video in full screen - really a bit of a deception as you were not the only one fooled by it.

Oh wauw, are you serieus? This was actually one of the reasons for me to finally jump ship and buy a 12.9.

Why do they mention the iPad on their Ultrafine 5K support page then as ‘supporting 4K’?

This is total crap if what you’re saying is true, totally misleading how they displayed it in their demo.

It is true. The 4K support is for video playback but for everything else, it's mirrored. I also have an LG 4K monitor.
 
Can’t say I’m not disappointed. Really a shame they didn’t implement that. I just read something about 16:9 support coming to the iPad with iOS 15. Just a rumour, or have some people discovered this in the betas released so far?

Not a valid rumor, just a wish. There is nothing in the betas to suggest it will happen. Everyone really wants this but it possibly may never happen.
 
Yeah, everything said is true.

As for why Apple markets the iPad as supported on the display's store page; Well, it is. It does support 4K output and all. But apps need to implement their own second screen support and you can only do so much with it, because the iPad is a touch-first device, and you can't do touch on a secondary display, so you can only really use the secondary display as a monitor and have no input through it, even with mouse and trackpad attached I don't think the API currently allows buttons on secondary displays but I may be wrong about that
