Is here a single adapter to cover both via and HDMI so i have both available if needed at presentations
Apple only do one or the other - any reason for this ?
I had the same issue so I bought and Apple TV and a vga dongle for it, so far the best solution, every thing works flawlessly, it even works with no access to wifi.
I ended up buying both dongles, HDMI dongle to connect to my monitor and VGA dongle for presentations. Works flawlessly, albeit a little expensive solution to buy 2 dongles. Then again one dongle with all ports on it would be kinda bulky.
