Roku Ultra and Visio TV Connection Issue

I'm having an issue where most of the time I have trouble getting the Roku to properly connect to either of my Visio TVs.  I've done extensive troubleshooting and am looking for a method to make the connection start up in a more stable fashion.  The details of the case are as follows:

 

First TV:

Vizio M470 SV

Fully up-to-date on firmware

Works perfectly all HDMI ports with any other device

Factory default configuration for TV settings

 

Second TV:

Vizio D55u-D1

Fully up-to-date on firmware

Works perfectly all HDMI ports with any other device

Factory default configuration for TV settings

 

Roku:

Roku Ultra 4802X

Fully up-to-date

Worked perfectly with two other monitors I tested it on

Disabled CEC settings / Tried automatic resolution, forced 1080p, and forced 720p

 

Tested wall socket with a multi-meter and oscilloscope, power is stable and clean coming from the wall socket most of the testing is from.  Tested alternative wall sockets with no difference in issue.  Tested multiple HDMI cables and HDMI cable testing shows good cables.

 

In 100 attempts on the first TV, 9 attempts resulted in a successful Roku screen and ability to use the device normally until either device was powered off.  In 7 of the failure cases, the TV displayed "Not Supported".  In 62 of the failures the TV flashed an energized black screen, then powered off a few seconds later.  In 4 of the cases the TV stopped responding entirely as if hung and had to be unplugged/plugged back in to respond to any input.  In 2 cases the Roku menu loaded but had interlacing issues, while appearing in black and white.

 

Second TV exhibits the same behavior.

 

I'd appreciate any suggestions taking into account what has already been tested/attempted.

      Emmanuel,

      The problem has occurred since purchasing the device.

      The problem does not occur when using display devices from other manufacturers such as a Dell monitor and seems confined exclusively to Visio manufactured devices but consistently occurs on any Visio manufactured device.

      As mentioned in my original post, the only error message present is an inconsistent "not supported" error from the TV which occurs approximately 7% of the time.

        Thanks for the follow-up, Xeroize!

        Could you also post a picture of the error message so we can take a closer look at it? Also, what specific models of Vizio TVs are affected by the issue?

        We look forward to hearing back from you!
