Photonis ECHO PLUS vs 4G+ Resolution Test

Описание к видео Photonis ECHO PLUS vs 4G+ Resolution Test

Side by side comparison of an ECHO+ tube and a 4G+ tube of similar specifications. Note that this ECHO+ tube performs to a higher standard than most other ECHO+ tubes, and may have been a 4G fallout tube due to a larger than allowable spot.

4G+ generally maintains better resolution and image quality throughout different light levels due to better parts selection and more stringent quality standards throughout the manufacturing process. 4G+ gives tangibly better resolution and contrast as the phosphor screens and fibre optic inverters are of noticeably higher quality than ECHO and ECHO+.
