[OS 12.0] Roku Ultra Dolby Vision Update after Firmware Update
Hello,
I have a Roku Ultra hooked up to a Yamaha sound system which is in turn hooked up to a LG C2 OLED 65" TV. I've had this setup since last November, 2022.
In display type, I set my Roku to 'Automatic (4k Dolby Vision)'. When using Roku, my system always came up on Dolby Vision. I know this because the words 'Dolby Vision' would come up briefly upon power-up in the upper right corner of the TV screen. Additionally, I can go into the TV display and it will show me what mode it currently is in and if dolby vision was on.
Recently, I started to notice the colors weren't as bright and vivid. After investigating, I began to realize Roku was not comming up in 'Dolby Vision' anymore. Being a technical person, I wondered if some firmware had been updated somewhere or perhaps I needed to install a new update. I got to looking in the Roku's settings and realized the Roku had automatically updated itself on 4/19/23. It is my believe my Roku and my settings worked fine until this software update.
I have gone back to settings. I can manually set the display type to '4k Dolby Vision HDR TV'. When I do, Dolby Vision works fine. Upon, shutting everything down and watching TV again at a later time, the display settings go back to 'Automatic (4k Dolby Vision)' on their own and Dolby Vision stops working again.
On a hunch, I checked the firmware on my Yamaha sound system and the TV. Both needed updating but did not resolve the problem.
I'm confident this issue did not start till the Roku updated its software recently.
Some information about my Roku:
Model: 4800X - Roku Ultra
Serial Number: X0100071PW41
Software Version: 12.0.0 BUILD 4175-C2
Any thoughts on how to resolve this? My setup is right now plugged into my sound system. The sound system then sends the video to the TV. I can hook the Roku straight to the TV and the TV will then send the sound via ARC to the sound system. I may try this and see if everything works fine again. If this works that will be a solution for me but that software update needs to be looked at.
Thanks,
Chris Smith
