I upgraded a Roku I'd had for many years for a new Roku Ultra Streaming Media player (since it had an ethernet port so I could hook it up to my cable directly). I was having issues with playback being pixelated at times.
For some reason, when the screen is ever black, I would see white dots like sparkly stars or snow or something but now I'm starting to see those blinking dots during movies I'm streaming. Any idea what's causing it or how to fix it? I didn't have this issue with the old one I had that I used to use through wifi. Thanks!
Re: White flashing dots on screen with new Roku Ultra
I found a solution for me. I changed the HDMI cable to a HDMI 2.1. I think the extra bandwidth may have made the difference. I got a short 50cm 2.1 from AliExpress. My Ultra is connected to an LG C2 and on the back of the TV with double sided tape. Flashing white dots are gone.
