Weird. I've been watching HTML5 videos in >720p resolution for some time now. What OS are you using? I'm using it on Windows. You enabled MSE via the about:config page, yes?

I enabled MSE in Firefox in the previous version, and the HTML5 YT videos seemed to work fine except 1080/60p videos, which stuttered a lot. As of v37, that seems to have also been fixed. YMMV, but it's A-OK for me.

It may not be on by default, and it may be 'incomplete', but I turned that on in Firefox some time ago and can view HTML5 YT videos in resolutions greater than 720p. It's certainly good enough for now (though I don't know why it's not on by default).

The original poster said >55", which doesn't mean he wants to jump straight to 100", which would make sense for projecting, but there are plenty of displays in the ~6x" category which are cheaper by almost an order of magnitude.

An inexpensive UHD projector? Where?

Killing off hope now, instead of just characters. Well played, sir, well played.

Go into the Dell "Work" section of the site - you can get this with i7 CPU, more SSD capacity options, etc.

Navigator 4, the browser that, when you turned off JavaScript, also turned off CSS. Good riddance. I really liked Navigator 3, though.

DaVinci Resolve, by Blackmagic Design, is used in actual Hollywood movies (though I don't know if those Hollywood studios are using the Linux version or not).
