IT WORKS!!!
In the bedroom is where we keep (and still use) our old TV. We haven't used cable in over 6 months since we got our Firestick in the Livingroom, so I decided to move our Roku 3 to our Old TV (no HDMI).
There are MANY converters online, but some had reviews stating that they did not work with Roku. Rest assured, this one definately works and no odd noise or bad picture/feed.
All you need is an HDMI to HDMI cable (Roku to converter) and an AVI (3-jack) to AVI cable (Roku to TV)...both of which we already owned. Now plug in the power cords for Roku and for the converter (non-powered converters are not good, in my opinion) and it's done!
I entered in the WiFi password for Roku (Roku settings, as normal) to stream Netflix and we started watching (see photos). Super easy, no codes or extra nonsense! We are VERY happy with this purchase. :)
