Overview

All 3G Ultra Receivers have a built-in video scaler. This enables a source to be set to the maximum resolution even when all displays may not support that resolution. The Receiver will adjust the output resolution so that the display can properly play the video.

Note: When scaling down, the Receiver can only go down to a minimum of half of the input resolution. For example, 3840x2160p (4K) can be scaled down to a minimum of 1920x1080p. Scaling 4K to 720p will not display correctly. Scaling up does not have this limitation.

Standard Resolutions

3G Ultra Receivers come standard with 6 scaler settings:

• Pass-Through: Does not modify the video resolution (default)
• Auto Detect: Matches the scaler to the information in the EDID of the attached display
• Full HD 1080p60
• Full HD 1080p50
• Ultra HD 2160p30
• Ultra HD 2160p25

Custom Resolutions

The scaler can also be customized for other resolutions. Scroll through the list of the dropdown menu for the output resolution needed. Not all of these output resolutions have been tested; your mileage may vary.
