The R, G, and B video signals in an analog computer display output are typically ____.

1. Combined into a composite video signal

2. Kept separate in order to preserve the best quality

3. Transmitted as radio waves

4. Transmitted as IP packets

The correct answer is: Kept separate in order to preserve the best quality

The R, G, and B (red, green, and blue) video signals in an analog computer display output are typically kept separate to preserve the best quality. This approach allows for greater accuracy and fidelity in the color reproduction on the screen. By maintaining the individual signals separately, the display can avoid cross-talk and signal degradation that can occur when these signals are combined. When the RGB signals remain distinct, there is more control over the color mixing process, leading to cleaner color transitions and sharper images. This technique is especially important in high-resolution displays where precision in color representation is critical. By separating the signals, the display can also utilize higher bandwidth, ensuring that the signals maintain their integrity from source to screen. The other choices suggest methods that compromise quality or are not applicable to analog displays. For instance, combining the signals into a composite video signal does lead to loss of quality due to the mixing of the color channels, while transmitting as radio waves or IP packets pertains to digital transmission methods rather than how analog signals are managed in display systems.
