I have a Roku HD/XR and it works just fine hooked up to my Vizio 37" HDTV via HDMI. However, when I try to connect the same Roku box to my Vizio 47" HDTV via HDMI I get static. I have been on the phone with Roku and also contacted them via email. No one seems to know the answer to this. I have switched cables, reversed cables, rebooted, reset, changed resolution before moving the Roku box. Nothing seems to work. Anybody else have this issue? Any ideas? I would really like to have the XR on my main TV since it can be set to 1080P and has the USB input. Help!
I have three Visio TV's - all worked fine with three different generations of Roku...no problem.
Then I tried to hook up a new "Smart" TV from Visio - and no matter what, the input on the HDMI ports from a Roku is unwatchable garbage.
When I call Visio product support - they say "It's a Smart TV, you don't need a Roku" and won't help me beyond that. Which may be true - but I have all of my setup on a bazillion streaming services and all of the cellphone remote stuff hooked up - and I'd like to have the same user interface on all of my TV's please.
I really don't want the Visio to be anything other than a dumb-as-rocks display.
So - I don't know what it's doing - but it seems to me like a deliberate effort from Visio to try to stop me from doing what I want. It seems to be deliberately making the ROKU image bad - with noise, lines and flickering along with poor color quality. It looks like a bad analog connection.
But this is a digital connection - it either works and gives you perfect signal quality - or it doesn't work at all.
This means that some annoying smart-ass at Visio *MUST* have written software to detect that this is a Roku and to deliberately screw up the display - making it ALMOST work - but in truth be unwatchable.
I can plug (for example) my PC or my XBOX into the same HDMI ports and everything auto-configures and works great.
CONCLUSION: DON'T BUY VISIO SMART TV'S ANYMORE.
