roku streambar. display keeps going black #

Roku Streambar  Hello, i have had my roku streambar for around a good 6 months. for the past 2-3 months. the display seems to go blank when watching a movie. it only last around 2-3 seconds. but it never used to do this. i have tried clearing the cache. leaving the device unplugged for 12 hours. resetting the device. and tried it on another 4k TV. and i also bought a better hdmi that support full 4K and it support hdcp 2.3 4k@ 120hz. so thought it couldn't be the cable. the device is mounted on a wall. the device always feels cool. i have tried neflix. amazon and youtube. it all happens after playing for around 30 minutes.

@man1234-

Does this sound like your problem?

Under "Settings > System > Advanced system Settings > Advanced display settings" does your Roku have an "Auto-adjust display refresh rate" item? If you don't have this setting, the rest of this post doesn't apply to you.

If this is enabled, the Roku circuitry sends the signal output at the refresh rate (frame rate) used by the original source material, commonly 24 fps (frames per second), 25 fps, 30 fps, 50 fps, or 60 fps. Every time the source frame rate changes, the TV must adjust its display to accommodate the new frame rate, which on many sets results in a short blackout or other display disruption that some find objectionable.

This can happen when starting/stopping new programs, and when going in/out of commercial breaks that have a different native frame rate than the programs they are inserted into.

If "Auto-adjust display refresh rate" is set OFF, the Roku converts and sends everything at 60 fps so the TV doesn't have to adjust on the fly and you don't get those frame rate transition disruptions.

The tradeoff here is that movement of things on the screen for non-60 fps sources may not be as smooth with no frame rate adjustment, depending on whether your Roku or your TV does a better job of refresh rate conversion. You have to decide whether this change is worth it to you.

Re: roku streambar. display keeps going black #

Did you ever have any resolution to this? I just bought a Streambar Pro and am having the same issue where the video signal cuts out every few minutes. I happen to have optical audio setup, since my TV is old and doesn't do HDMI-ARC, so the sound does not cut out, just the video. This is happening with both the included HDMI cable as well as others I've tested. I've tried toggling back and forth automatic and manual resolution setting. I've tried toggling the auto-adjust display refresh rate setting. Nothing has worked for me so far and I'm about to return the unit since I'm still in my return window.
