Re: Connecting the Lifestyle v35 to a 4k TV
Thank you for taking the time to post and welcome to the Bose Community.
Your Lifestyle v35 will be able to support Uncompressed PCM 5.1, Dolby Digital, DTS and Dolby TrueHD. When you connect with optical, you'll likely have the option to choose Uncompressed PCM 5.1 which will offer the best quality of audio for your set up. To ensure this is enabled, you'll have to go into the audio settings on your 4K TV, look in the audio settings and check that under audio format PCM has been selected.
Let me know if you have any issues going about this!
