YouTube has adopted a more responsive page layout to cope with videos having different aspect ratios <https://arstechnica.com/gadgets/2018/07/youtube-picks-up-dark-mode-on-android-loses-black-bars-on-the-web/>. To no-one’s surprise, this has annoyed a few people who have become accustomed to the old design. When 16:9 widescreen TVs were being conceived way back in the 1990s, the aim clearly was to allow us all to view cinematic movies full-screen, making maximum use of available screen area with minimal or no black bars. Nobody foresaw the widespread popularity of smartphones with built-in cameras, and of the common use of footage captured with such devices in TV broadcasts. But while such phones commonly have 16:9 screens and their cameras capture 16:9 footage, their users often hold them vertically, so the image ends up in just about the worst shape for display on a regular widescreen TV. There seems to be a common convention nowadays of filling in the gaps with blurred portions of the actual image -- which I agree looks less jarring than black bars. Hmmm ... there have been computer monitors that can be rotated to portrait or landscape orientations, with automatic adjustment of the display to match (aka “xrandr” <https://wiki.archlinux.org/index.php/xrandr>). Wouldn’t it be useful if a TV could do the same...?
