Answer 2

Properties Of Video Display Devices is given below:-

Explanation:

Persistence:-

• The key difference between phosphorus is its consistency. It determines how long they will manage to emit photons after the electric field is withdrawn.
• Persistence is characterized as the period the emitted light decays from the screen to one-tenth of its initial brightness.

Resolution:-

• Resolution means the minimum number of points that can be shown without overlapping the CRT
• The resolution depends on the form of phosphorus, the strength to be reflected, and the concentrating and deflection methods used in the CRT system.

Aspect Ratio:-

• The proportion of horizontal points to lateral points is used to establish equal duration lines on the display in both dimensions.
• The proportion ratio of 4/5 means that the black line labeled with four dots is also the same width as the diagonal line plotted with five stars.
