This may well be answered in the documentation somewhere, but I haven't found it yet.
We are considering getting a PC with a video card that will support a 4K TV as the display, and using that for a PAC Display HMI system's main screen. With that resolution, and with a large display, we can not only see the indicators and graphs from a reasonable distance, but then also see good detail within the various graphs when we approach the screen.
But what I don't know is if there is an upper limit to the resolution supported by PAC Display.
A 4K display has a native resolution of 3840 pixels × 2160 pixels. This is also referred to as UHD or 2160p. Naturally, we don't want to get a PC/Video card and display until we know for sure that PAC Display will fully support this high resolution.
