Battery-Powered Touchscreen Model

I have bought a few uperfect monitors and all have worked for my devices: desktops, laptops, android phones, ipad pro, mini PCs, game consoles. 15.6" 1440p @ 120hz 15.6" 1080p @ 120 hz 15.6" 1080p @ 60 hz w/built in battery 13.3" 1080p @ 60 hz wireless lapdock All of these support dp over type c along with hdmi, if it's mini hdmi, the monitor comes with its own hdmi cables I've bought a magedok 1440p.monitor from amazon before but Im not happy with the build quality.

Well, thats weird. I have a touchscreen 15.6 monitor and a broken S10+ and a functional S20FE. Both can power up the monitor and display image just fine directly into the usb-c port (cable need to be usb-c video compatible). Otherwise, the S10+ cannot go into Dex mode that way, only mirror, so I need to plug another Usb-c cable to the monitor providing power, in which the second usb-c slot also has power pass-through and goes into the phone as well, not needing a HUB for that (slow charging tho). I wonder if newer phones past the S20 can power up the screen and go into Dex Mode as well, because that seems the case. For the measure the monitor has 1 - mini hdmi to Hdmi port 2 - 2 usb-c ports that support power, video and data (in case you connect into windows and want to use the touch screen) The brand is Uperfect if anyone is interested, the model I have no idea probably a generic one.
