Wireless display adapter for Windows, Android and Apple?

AlanX

I am looking to connect various devices to a club projector wirelessly. I am looking at the Microsoft Wireless Display Adapter v2, which looks ideal for my Windows laptop.
However, I also want to connect (at different times), an Android phone or tablet, and a Mac computer or iPad. Tall order?
I see various devices (at ridiculously low prices) on Amazon that claim to do all three via Miracast or Airplay. Are they any good? Image quality is very important, but latency not so (we'll be looking at still images, and certainly not gaming).
One important aspect is that the connection must work stand-alone, that is with no hotspot device or Internet connection - just the device talking to projector.
Anyone got any views on, or experience of, such things?

I think without an internet connection (no wifi) and looking at the multitude of technologies that you wish to connect you may struggle with a single device. Most rely on a wifi connection between the device and the receiver. I maybe proved wrong, but without wifi infrastructure I have not come across such a device. There are devices, such as the Airtame which will do this, but it needs wifi infrastructure to work. Maybe you could look at using a wireless hot-spot to facilitate it.

Yes, you may be right. I'm led to believe the Microsoft Wireless Display Adapter is stand-alone, that is, it will 'talk' with a laptop without the presence of a router or hot-spot. AirPlay probably needs a 'proper' network, but that is total overkill when all I want is to connect my laptop/iPad/Android tablet to an HDMI projector without a cable.
I believe some Android devices 'do' Miracast like Windows devices, so the MS device might cover them as well. But there are questions over which versions of Android actually do this - I heard that it was introduced but then dropped in the most recent updates. Most (or all) Android tablets are without HDMI connections, so perhaps wireless is the only way - unless its USB port can be converted with an adaptor. I really am in the dark on this, and don't want to start spending money till I can get some assurances from folk who have done it.

Almost all Android phones and tablets support Miracast. Google's own hardware is the main exception, that only supports Chromecast.  Other Android devices may not, but you're probably not going to be streaming from an Android Auto or Android TV device.

Android has poor support for DisplayLink and other USB Graphics devices.

You say it's only for static images. If they're image files in a common format, or can easily be made so, then some sort of media streaming setup is likely to have the widest compatibility. DLNA streaming as it's often called.
