3G Ultra Receiver Comparison


The Just Add Power 3G Ultra system is capable of accepting 4K60 input, but outputs a maximum of 4K30 at the display end. "Receiver" describes the display-side decoding device and there are various models meant for different requirements at the display location. All models are compatible with each other so they can be used in the same installation. Use this article to help with choosing the model that best serves the video, audio, and hardware needs of each source location.

Units labeled as 2GΩ/3G are part of the 3G HD over IP System, but have a maximum supported resolution of 1080p. This distinction allows 1080p installations to take full advantage of all features in the 3G System without the additional cost of 4K compatibility when it is not needed. If you are planning a new 1080p project, see the 1080p Receiver Comparison article instead.
