Not just resolution, but overall sensitivity as well - meaning that green light of the same intensity looks brighter. This is also why most night vision devices use green phosphor, why some flashlights have a green LED (less energy for the same perceived brightness -> more battery life), and why green lasers for pointing/marking are increasingly common. Since black is the same black in both cases, a green CRT will therefore has a higher perceived contrast. |
