Frequently Asked Questions
Why do classic matches stretch by default?
Modern TVs default to '16:9 Full Screen' to eliminate black borders, which artificially stretches 4:3 archive broadcasts.
What is Pillarboxing?
Pillarboxing places vertical black bars on the left and right sides of a 16:9 widescreen to display 4:3 content in its true shape.
