ECHO, HDMI Upscaler/Downscaler

SKU SW-32871


Match the native resolution of a different display when multiple displays are used. Perfect for use with switches, splitters, matrixes, and any other application using multiple displays with mismatched resolutions.

The Echo is a universal converter for HDMI input to HDMI output. The scaler up/down scaling employs black/white level expansion, color transition improvement, dynamic range expansion, blue stretch auto-detect and auto-convert.

Note: The Echo does not support HDCP 2.2 content.


Downscalers are often used in setups that use HDMI splitters to send the same image from one video source to multiple displays.

For example: If your video source can output 4k (2160p) but one of your displays only supports up to 1080p, the splitter will automatically send a 1080p resolution to all displays even if some of them can support 4k.

By using a downscaler between the splitter and the 1080p display, you can "trick" your HDMI splitter into thinking all your displays are 4k.


Upscalers are often used to help match signals between devices, such as with video recorders. For example, the final recording needs to be a 4k@60hz recording, but the video source is only 1080p@60hz. So the upscaler will help convert that signal to match the recorder's requirements while enhancing it using advanced techniques rather than simply stretching the pixels.

Some newer 4k TV's already have built-in scaling, so an upscaler is not needed, but a scaler can be useful for displays that don't have built-in scaling or the built-in scaling is not good enough.

Does what it said it would'

Pros: Scales nicelyCons: Can't think of one. Maybe if it had more frame rates, that'd be cool. Other: Plugged it in- it just works. Can't ask for simpler operation.

Part Number: SW-32871

Pros: Works great and performs as expected.Cons: Sometimes when switching stations in direct tv seems to cause issues and tv hesitates to show output. Waiting usually resolves this issues.Other: I am not sure if it's caused by the upscaler or other cable issue.

That could be some sort of compatibility issue, or possibly something with the cable box itself. You can give our tech department a call for some help getting that issue resolved if you'd like.

Downscales From 1080p Perfectly

Pros: Perfect image quality when downscaling 1080p60 to 720p60.Cons: Only 30Hz output for 4K. Since I'm not using 4K yet, this isn't an issue for me.Other: I'm using this to downscale from 1080p60 to 720p60. It's driving an unpowered HDMI-over-cat6 balun pair, with dual 100' cables, and the image quality is perfect. The unpowered balun will not carry 1080p60 to 100' (the signal is garbled) but 720p60 does work at this distance, so I put a 720 set in the remote location. I am not sure if the device is remembering the last output resolution, or if it is using EDID data, but it doesn't change from 720p60 when power-cycled. I manually set the output resolution to 720p60 prior to connecting an actual 720p60 set. If I do figure this out, I'll update the review.
