The 1940s brought us even higher resolutions.
Including, the NTSC standard, of 480 lines of resolution and better audio. In the 1940s it was difficult to produce CRT screens larger than 12 inches. So big screen TVs implemented projection techniques. -

Such as the rollable TV. It is completely hidden when it's off and when it's on, it grows to the size of the content or application. Avoids the black bars in extra-wide movies.
