Earlier this year when we reviewed the Aputure VS-2 FineHD HDMI monitor, one of the downsides we found was that the monitor could only accept up to an HD signal from your camera.
The trick with that is that some of the 4K cameras like the Sony A6300 and A6500 evidently could not down-sample to HD on their HDMI output port and record to 4k internally at the same time. So this monitor just was not a good fit for those cameras.
The Panasonic GH4 could down-sample to HD and record 4K internally but autofocus performance slows when doing this. Not a deal-breaker for everyone, but not ideal.
But now, with the new, free firmware available as of this week, the VS-2 FineHD can now take a UHD (3840x2160 up to 30p) signal. Of course it still only displays it as HD, but this solves a big problem for those shooting 4K cameras. Thanks Aputure!
We'd love to see the same thing for the new VS-5 monitor which I'm in the process of reviewing!
