I was in the same situation when I started Zwift, as I was tiring of taking my laptop to the basement and connecting it to the TV (which was already there because I used to watch cyclocross while on the trainer). My solution was to get an Apple TV 4K. It’s worked out very well, as I can also use the Amazon Prime Video and NBC Sports Gold apps (and plenty of other stuff) on the same TV. The ATV graphics (for Zwift) aren’t as great as some of the computers, but they are good enough for me, and the price point is hard to beat.
I have a Lenovo IdeaPad 5 with i5, it constantly freezes mid ride but not on all rides just random ones. I changed the UHD and seemed to work fine for about 2 weeks and now its freezing again. I meet all the requirements so not sure what to do next .
