4K USB-C video input?
I've seen a few threads discussing FHD input, but I'm hoping people can confirm the GXR is capable of receiving 4K USB-C video input via a 4K capture card (ETA: not just receiving, but playing 4K too).
Source > HDMI/USB-C cable > 4K Capture Card > GXR > Noir Lite app (or ?)
If this is working for you, please share which capture card you're using and if there's any perceivable lag.
Thanks!
