The monoscope signals are the integral part of the central signal system of the test patterns, used to adjust and align the geometric aspects as well as the visual aspects of the display panels. All basic alignments are performed on monoscope signal. This vital test pattern is sometime corrupted with color transients, which adversely affect the quality of the signal. The presence of color transients disturbs the alignment process of the display panels. In this paper, we present a technique to detect the presence of color transient interference in the signal by analyzing the signal waveforms on oscilloscope. The analysis reveals the cause of its presence and also suggests the suitable measure to suppress and to reduce the effect of the same on the quality of the signal. The analysis of monoscope signal waveforms reveals the core and basic components of the complex waveform that constitute the monoscope test patterns and provides the tool to control each and every parameter of the pattern. This novel research presents a solution to virtually analyze the behavior of the pattern when color transients affect the signal, and at the same time suggests the steps to be taken to reduce the effect of the noise on the signal.
