That makes me think though that the price tag doesn’t belong with this product. The tag clearly says “1 piece” and also says “razor” (singular) while this product is a box of 8 replacement heads.

So 1920 rows x 1080 columns.

Unless I have a massive brain fart right now, no, that’s the exact opposite. The screen is wider than it is tall (unless you rotate by 90°) - hence the term widescreen. There are 1920 columns (width) and 1080 rows (height). This is why the sticker is confusing: it indicates that 1080 pixels is the width.

I once tried setting up exactly this (shared NTFS drive for games) but gave up shortly after. A lot of games would suddenly stop working between reboots, validating the games through Steam would basically redownload the whole game - just too much hassle for me.

My assumption: kWh/100 km. That’s the unit generally used in Germany (and probably all of Europe), unless you’re Tesla, in which case you use Wh/km.
