The master volume on the box may be set too low...you can unpair the remote from your TV, increase the volume, and then re-pair the remote to your TV. Instructions on unpairing/pairing here: https://www.telus.com/en/support/article/telus-tv-digital-box-remote
The box uses adaptive bitrate streaming, so if you're not connected via ethernet or if your Wi-Fi signal strength is less than optimal/network is congested, this will affect resolution.
Is there a particular setting in the menu that you're looking for?
