Commissioning:
My Full HD projector has no normal USB port, but only a "small" (as in older phones, so the slightly higher, not the very narrow). The supplied WiFi antenna has only one large on the breakout cable. According to the description the WiFi antenna is optional, so that I can also connect a simple USB-AC adapter to the dongle should. Dongle to HDMI, power supply to the dongle and whoosh starts the dongle in anycast mode for Apple devices. Looked again in the handout and there is that I should press the Fn button on the dongle to switch the mode. Try - nothing happens. No change of the mode, no error message, nothing.
After some trial and error then get the conjecture that the WiFi antenna is perhaps not as optional as alleged. From my tablet I have laying around a power supply without cable, USB cable of WiFi antenna in there, provisional power cord extension then (the cable to the breakout cable is so short that it is unsuited as a power supply cable) and then tried - and now settled in change Miracast mode and connect the Android device with it.
Weaknesses so:
-> To short USB cable to the WiFi antenna
-> No way to use a standard USB power adapter with cable
-> False description (WIFI antenna is not an option, at least for Miracast)
Initial tests:
As described, the display contents of the Android device is mirrored and the sound will be sent with the same (phone / tablet is muted and the sound is running via HDMI). This comes in handy with a television, with a projector without speakers rather not. In my Tablet, it is at least so that when using the headphone jack there is sound carry over and be there with active speakers or headset something can make - but these are again restrictions.
The picture quality varies greatly depending on the application. Photos and static screen content is transferred in high quality. Videos seem to me more of a stopgap, which I can not say exactly what it depends. youtube / clipfish / ... and local videos about work (even in Full-Screen), max cathedrals not (there is only the sound transfer). Maybe it prevents the max cathedral app, perhaps the data rate for HD content is just too high. I do not know, does not work anyway. What I have not yet tested is max cathedral to stream videos in standard resolution, which, if it should work, no really useful application would be - for standard resolution also reaches the tablet display more than perfect. Main problem is anyway what looks good or acceptable on a tablet display on a large screen quickly only grottig.
That is, the solution here is:
-> In order to receive images, presentations and other static content on a big screen
it is not really for:
-> Video streaming in high quality (at least not in the applications tested to date)
So if the dongle toying here, should check whether the USB port is on the projector / TV in close proximity to the HDMI input, or even order the same a USB extension and whether it is a "great" standard USB port is. In my view, the product would have merely by user friendly when the Dungle two micro USB ports would have (for a WiFi antenna and a commercial for any USB power supply) and would correct the documentary.
The restrictions on the video stream may be due to the apps, the tablet or the Miracast protocol (and perhaps not to the specific product here) - but the expectation arouses the product description already, and the reality is disappointing in comparison. So all in all, recommended limited.
