Thanks for reaching out here, @Bigdogscc!
We understand that your TV's screen became darker after the latest software update, and we want to check it out further.
To give us more idea about your concern, could you share some info?
- Is this happening on all channels or only on a specific channel?
- Could you provide a photo of it so we can take a closer look?
Please get back to us soon!
Best,
The Roku Community Team
