The present invention is a system and method for monitoring FED performance and compensating for adverse impacts associated with display emission generation. A present invention FED adjustment system and method is capable of providing real time emission characteristic monitoring during retrace periods. In one present emission compensation method a feedback type process is utilized that drives a constant level on dummy pixels not included in the active viewing area and compares the results (e.g., the current that is associated with the emission) to an expected certain predetermined amount. If the current is too high then the voltage supply is reduced to the drive level or if the current is to low the voltage is increased. A driver voltage is supplied and an image is presented in an active pixel region during an active presentation time. Emissions are produced in a test pixel during a nonactive presentation and a determination is made if the emissions in the test area are accurate. If the emissions are not accurate, adjustments to the pixels are made to provide a desired level.
