I meant in watching episodes on https://therokuchannel.roku.com/ on a laptop
I was talking about Resolution.

No Roku device supports 1080i output. Since 2017 the only available resolutions for any Roku player has been 720p, 1080p and 4K devices support 2160p. Some older players had composite (analog) outputs which offered 480i (the old analog broadcast TV standard). 1080i has never been supported.
The original question was asking about The Roku Channel specifically. There is no quality/resolution setting available when playing content on that channel. Whatever resolution Roku has for the content is what is streamed. I don't personally know if they offer any 4K content on TRC, but if you subscribe to a different provider and access that content through TRC then 4K might be available.
Remember that TRC offers a lot of older content and might only be available in SD quality. Many TV shows continued in standard def well into the early 00s. Any higher quality would depend on how the content was originally recorded and stored.
