Dell S2317HWi 23" 16:9 IPS Wireless Connect Monitor w/ Wireless Charging Stand (2-Pack)

Correct. I was able to get it to display from Android out of the box and from Windows 10 after upgrading the wifi card on the computer to a dual channel, but never had it work with my iPhone. I honestly haven't tried it in the last year after the last few IOS updates.

As monitors are all agnostic, this will work as long as you have the correct cables or adapters.

Yes, it will. The only word of caution is that it may not charge as quickly as you want it to. That is my only gripe with the built-in wireless charger.

You can use your laptop display and the wireless display together....but only one wireless display. It appears to use WiFi.. Microsoft recommends enabling WiFi and Bluetooth on your laptop.

I don't think so. The manual shows two usb inputs connecting a Mouse and Keyboard. I tried plugging a thumb drive with jpegs and tried to select an input and still the only options were only HDMI, wireless and auto select. With auto select option on, still nothing changed. Thinking the next best option would be to cast my cell phone Galax S9 to it, I went to the app store, got the dell wireless connect app and it connected. So you may want to create a slide show on your cell or even an old cell phone and cast it to the monitor wireless.

Looks like it is designed for stand use only. There are no screw holes in the back

No - the wireless options are only Windows and Android. I tried with my IPhone but no luck.Im going from data port to HDMI and so far havent been able to get the speakers to work.

It is picky about the wifi card chipset. I can't find confirmation of the chipset of your wifi card, but it is a replaceable card. Worse case, you can pick up a $30 Intel Wireless-Ac 9260 card to replace yours and it will work fine.
