> Biggest lie ever. People want 16:10, but for years the industry shove 16:9 to your customer because it was the cheaper panel. Any background on this? I always assumed 16:9 became popular because of videos.
I have a MacBook Pro with 3456 × 2234 (around 16:10.5) resolution and it is perfect . I don't know why people would want laptops at 16:9 at all. I can play videos just fine on this thing and the other 95% of the time it's a better resolution for doing things like coding and spreadsheets.
Depends on the use case. my wife (accountant) lives in Excel, and I set her up with two 21:9 monitors side by side (42:9 overall) and she loves that setup compared to the one she has in the office.
