My new Roku Ultra keeps losing its HDMI connection to my TV

This is a nice addition to the Roku lineup but it has a major flaw.  Once it started happening to me, I checked the internet and found out that quite a few others are having similar problems.  About ...

    I had the same issue with 2 ROKU Ultra’s and my Visio TV. The fix was going into the ROKU Ultra advanced video settings and changing from Auto Detect display type to 4K HDR TV. Never lost the signal after that. 
     

    for some reason the ROKU thinks my TV is compatible with Dolby vision and selects that type when it’s in AUTO. But that leads to a No input and a blank screen

What do you mean “when” are your choices?

When you go to Settings, display type, what options do you see? You should be able to select between  4K TV or 1080 TV or 720 TV, or Auto Detect ect..

Select the right one for your TV. Do not use Auto Detect, or 4K Dolby Vision TV (even if that’s what you have) 

 

Also check: 
Settings, system, advance system settings, advance display settings. Auto adjust display refresh rate = on.

      We bought good quality HDMI cable & ended up claiming a warranty on our Roku ultra for doing the same thing. The 1st day we installed the new on sent from Roku it did the very same thing. Any ideas what to try?

        Generally, the possible causes are:

        1. TV HDMI port
        2. HDMI cable
        3. Roku device

        While there could be other things, these would be most likely.

        You indicated, but didn't specifically say, that you changed HDMI cables. Yes, you said you bought some new ones, but you never said you first tried others. I'm going to assume you did, but if you only ever used the one set, then you need to try another cable and test this.

        You changed out the Roku device. Yes, it's possible for two to be bad, but not likely.

        That leaves the TV HDMI port. Most TVs have multiple HDMI ports. Try another one.

        Also, if you have a device connected to one of the other HDMI ports, power down, unplug the HDMI cable from the other device and plug it into the Roku, then power up and see what happens.
