You could install the YouTube Plus browser extension and check "disable DASH playback" in the settings. Then if you start playing a video for a second or two and pause it, it will buffer the entire thing. The only downside is I think it reduces the maximum video quality for all videos to 720p.

I have a 1920x1200 monitor, so yeah I don't think so lol.

So do I and it's what I do. I can't really see much difference between 720p and 1080p on YouTube.
