Every thinkpad released in the last 5 years has had screens with 100% adobe rgb color accuracy. They’re almost all at least brighter than 300 nits. Some brighter than 400. They’re objectively incredible screens. 1366x768 hasn’t been the standard in a long time. 1440p has been an option for a long time too. As far back as the t460 or the first gen x1 carbon like 10 years ago. The last ThinkPad I can see where 1366x768 was even an option was the t490 in 2017. After that they moved onto 16:10 screens and made 1920x1200 the minimum. Hell even 1800p OLED screens have been available in some models for 7 years. The t570 and p50 both have 4k screens and they’ve been available for about 7 years as well.
Look into smarttubenext for Chromecast then. It takes like 30 seconds to install. It’s similar to new pipe. I believe it can even link with new pipe to download videos for offline use.
It’s the entire reason I bought a Chromecast over a Roku or fire TV.
