Care to elaborate? Sure, manufactures could’ve done 21:9 (roughly 2.35:1), but from what I’ve seen, that wasn’t practical at the time. 16:9 was a good compromise. Especially for people who stretch 4:3 SDTV content into 16:9 instead of using black boxes; 4:3 content would look horrible on a 21:9 display. Nowadays though, 21:9 is becoming popular, and it has a ratio of 2.333:1 which is pretty close to a cinematic 2:35:1. If only Windows made snapping three windows side by side easier.
