These foldables are a great demonstration of why the screen diagonal is an unintuitive metric. This device has a 5.8” screen when folded, and a 7.6” screen when open. Looking at those numbers, it doesn’t sound like a very big difference. Yet anyone can see that the 7.6” screen is twice as big as the 5.8” one! The diagonal only made sense for TVs because the aspect ratio was fixed at 4:3 (and later 16:9). It shouldn’t…
>The diagonal only made sense for TVs because the aspect ratio was fixed at 4:3 (and later 16:9). I'm not entirely sure it made sense even then. I completely understand the point (knowing the AR allows one metric to consistently compare and derive the other dimensions) but in my opinion, diagonals became ubiquitous because when looking at TVs, bigger was typically better in the consumer mind and the diagonal is of co…
That make it easy to claim “4K resolution*” for a device that, perceptually, is nowhere near the quality you’d get from a 4K monitor.
