In case of aperture grille, stripe pitch is the distance between adjacent stripes of the same color. Smaller the dot or stripe pitch, sharper the picture. Resolution Resolution is the total number of dots or pixels a monitor can display at any given time, expressed in horizontal dots by vertical dots. In case of 1024x768, it means the monitor can display 768 lines, each line made up of 1024 pixels. It is the ability of the video circuity to turn a single pixel on or off.
Poor bandwidth can cost for screen brightness and loss of picture sharpness.
The higher the resolution or fresh rates, the higher bandwidth required. The annoying screen flicker occurs if the refresh rate is not high enough to repaint the screen quickly or when using interlace refresh technique. The dynamic focus is the extra element in the CRT gun that continuously adjust the focal length of the beam and convergence points of the three beams to reduce focus variation dramatically and ensure consistent performance. Convergence Convergence is the merging of red, green and blue color beams come together at the same point. In real world, perfect alignment of all the three colors is difficult.
