Question 1

The jtdat5ch has no audio output when the hdmi output is plugged into an hdmi to dvi adapter. does the jtd4katsw suffer this same limitation?

Accepted Answer

yeah, DVI is a video only connector, audio doesn't go near it. which was why HDMI was so revolutionary as an all in one cable.. your issue is your HDMI going into this J-Tech unit is that it doesn't have any audio information at all, just video. so what you need is a DVI to HDMI converter box that combines the dvi signal with a digital audio output from the source (either coax or optical) to a regular HDMI signal.. a simple gender adapter won't do that, need an actual converter box and I did a search and only found ones that had analog 2ch audio, not digital audio but it'd at least work.. or just connect your computer to the monitor or receiver diraectly via the computers digital or analog audio outputs separately, tho this doesn't help with tv's.. if you were looking for this as a solution for no audio on tv, this J-tech isn't it. it is used for older audio devices that do not accept an HDMI connection (either directly from an HDMI source such as a console, bluray, or other and then connected via hdmi to the tv while you use the optical output on this device to go to an audio receiver or plug all your hdmi output devices into the tv and take the audio output from the tv's ARC/eARC HDMI output.. this is how I am using it as my tv's optical output doesn't allow for volume control and I don't wanna use two remotes plus it converts dolby digital to a 5.1 format the optical connection can handle as it can't transfer it due to limitations of the format. only ARC/eARC can transmit it but I only have optical inputs on the receiver..)

good luck!

Question 2

Does the hdmi arc support also adjust the rca output volume? I would like to control the rca connected speaker volume via the tv remote control

Accepted Answer

No controls, straight thru

Question 3

I have a smart tv with no cable box. I want to use it for netflix and other apps. Would this work or do i need a cable box?

Accepted Answer

If your TV has an HDMI ARC input this will work. You will just need to plug an HDMI cable into your HDMI ARC input and the HDMI output of this device.            Adam      Support Team      J-Tech Digital, Inc

Question 4

Does it support 120hz and vrr ?

Accepted Answer

This can support 1080P at 120Hz in pass edid settings, given that your display also has that capabilities. It does not support VRR.            Saud      Support Team      J-Tech Digital, Inc
