hp-prime with miniHDMI port

Until such an option becomes available you might consider running the Android emulator instead - some phones have the capability to output the phone screen in HDMI format to a TV etc.

My own phone doesn't offer that, so I cannot confirm.

Of course, HDMI resolution would be even better.

Update: Check before buying - some specs only refer to video playback, no screen display.
