An LED visual display apparatus includes a plurality of LED pixels arranged in a generally rectangular array and each having a substantially identical construction. A controller controls groups of the LEDs to produce virtual pixels. In some instances, the construction of each LED pixel consists of 6 to 9 LEDs, inclusive, includes a plurality of red LEDs, a plurality of green LEDs and at least one blue LED, and has more red LEDs than green LEDs. In some instances, the array includes rows of LEDs that consist only of green and blue LEDs which define a repeating green-green-blue pattern. In some instances, the array includes rows of LEDs that consist only of red and green LEDs which define a repeating red-red-green pattern.
