Often these devices will only offer 240 active scan lines however. An LCD with 240 scan lines, even with a K factor of 1.0 will only reproduce at most 240 vertical lines of resolution. Vertical resolution is dependent on the system technology and is largely independent of system bandwidth. Similarly, horizontal resolution is defined by the number of horizontal elements that can be captured by a camera or reproduced on a monitor. Horizontal resolution thus tells us how many alternate black and white vertical lines can be discerned in the width of the image.
Horizontal resolution is highly dependent on system bandwidth.
Like a chain, resolution of a video system is only as good as its weakest link. All rights reserved.
