Narrative:
Unknown aircraft sighted on tis display approaching from the northeast toward the southwest. I was flying west as the unknown aircraft appeared on display. Altitude was indicated between 100 feet above to 100 feet below. The unknown aircraft appeared to be on a direct collision course and closing.a turn to the right would have put me over homes and I was concerned about potential impact. The tis display changed from white to yellow. I made an immediate diving turn to the left rolling sharply and steeply to the east. I thought impact was imminent. I dove low and then pitched to gain altitude.I never actually spotted the unknown aircraft. A very scary event. I was unable to fully evaluate the turn; meaning; other traffic; airspace; obstructions; etc. Survival was the drive. I will fly with the display at a scale to allow more area to be seen and allow more time for reaction.
