Glenwing,
Thank you, I have been looking at the HDMI multiviewer devices, and even tried one out that looked like it might actually output 3840 x 2160, but no luck, it just resampled the end result down to 1920 x 1080, which seemed like a lot of undesired work.
So far I have not found any multiviewers that support 3840 x 2160 output. Does anyone know of a device that actually supports that resolution output?
Thank you
