I have just started, within last week, seeing pixelated edges on my screen when watching my Roku. It is not all the time, but frequent. It's very apparent when the screensaver is on, because the rest of the screen is black. I have attached a picture. See the bottom row. Sometimes it is the bottom row and the right edge.
I am hooked up via HDMI. Never had this problem with years of Roku's across different devices. This is a 2018 Roku Ultra.
Any ideas what I can do? I restarted the device, didn't help.
I would recommend changing the HDMI port that the device is connected to, or swapping out the HDMI cable to confirm that something hasn't occurred with the cable that may be impacting the device's display output to the TV.
I'd also recommend checking for any system updates to see if any are available. If so, does the same issue occur after performing the update?
I'll try and change the port later. Changing the cable would be a nightmare, as it's run through the wall. The cables are pretty high quality, installed April of this year, and are not in a position to be touched, meaning physical damage is not really possible. Been working great since installation.
I'll change the port and report back after some usage.
