4.0 out of 5 stars Got most of what I wanted .....
Reviewed in the United States on 25 April 2019
I was looking for a seamless switcher to feed an encoder for streaming video --- which is not exactly what the J-Tech was designed for. Whenever you use a device for something other than it's intended purpose, it's buyer beware. :)

Here's what I found out: First the picture quality is pretty good. No complaints. Of course I was feeding it from two camcorders so it wasn't exactly the most challenging test.

Second: There was some kind of HDMI handshake incompatibility with two of my three capture devices. My monitor showed the J-Tech output, and my Magewell USB capture did bring a picture into the laptop. However, neither the Teradek Cube nor the Inogeni USB3.0 would show any picture at all.

So I hooked the output of the J-Tech to a KanexPro DA and guess what ... both Teradek and Inogeni were happy. (see picture 1). I'm not an HDMI specialist ... I guess there was some kind of handshake incompatibility.

Third: Referring to picture 2, you can see that in some multi-view modes, rather than place bars around a picture and maintain the aspect ratio, the device squeezes video to fit the box. Notice that the mouse is distorted. I am not using the multi-display mode for webcasting but if that's important to you, then keep it in mind.

Fourth: The switching was smooth enough that none of my capture devices reported a loss of signal. That was my primary concern and I can say that yes indeed, the switching is seamless and really quite fast. I'd estimate less than 200 milliseconds.

I like the fact that you can lock the audio output to a single source, but I didn't test it so can't report on results.

In case the manufacturer is reading this ... what I would like in a firmware update, is that you can switch video sources, not just audio, from the numbered buttons, so you don't have to cycle through all four inputs. It would be very nice to select input 2, then 4, then 3 ... or whatever ... Should be easy enough to do.

Also, the only "on / standby" control is on the remote. It was not clear to me that the unit could be turned on or off from the front panel. If the battery in the remote dies, or you lose the remote, can you still turn it on and off? I didn't test that but it seems safer to put an On/Off switch somewhere on the actual unit.

Update: The unit is no longer working ... I only get a blue screen output.
