So I ordered a Choetech from NewEgg for 9.99 we'll seeI have on the j716. My monitor has usbc input, that works fine, and I also have a cheap choetech USBC to hdmi convertor(I bought 3 years ago), also fine. I doubt anything special is needed. One thing I did find is zui 13 added more options, unless I failed to find them on earlier version.
P11 Pro TB-J706F.There are people using HDMI output so it might be the adapter or something related to the rom.
Is your tablet the Lenovo Tab P11 Pro or the Xiaoxin Pad Pro?
Can you post the brand and model number please?No, it mirrors the screen, so it had some black bars all around, it was not bad but in my TV I can adjust the zoom vertical and horizontal so now I have no black bars.
In the post I linked previously it says it can be used as second screen with native resolution with some tinkering on adb but I did not try yet.
Also to answer @flhthemi I did not have to change any setting, when I plugged in the cable it asked me if I wanted the sound to go on HDMI or internal and it just worked.
This is the item but I bought it locally in a shop
