Maybe you have a better quality laptop than I do. You undoubtedly have better eysight and hearing than I do
I also have a hearing issue, and am mildly short sighted. I find it better/more comfortable to watch tv on a device as headphones/earphones provide closer sound, and also block out ambient noise which makes it harder for me to hear. Watching on a device also means I can use subtitles, or read lips more easily, and without having to find my glasses.
In laws have a massive tv and speaker system as they are hard if hearing. It’s got to the point where you can’t have a conversation with them as the tv is so loud in the background.
Different things suit different people and catering for different abilities suits different people.
