Popularized by panoramic gaming monitors (3440×1440 UWQHD, 2560×1080 UWFHD) and anamorphic theatrical cinematography. Technically defined in consumer monitors as 64:27 (~2.370:1).
1. Calculating Proportional Dimension:
Width = Height × (Ratio_W / Ratio_H)
Verify that your custom ratio w matches the expected string format. Load a built-in sample preset to compare structural formatting.
Check the custom ratio h setting in 16:9, 4:3, 21:9 Resolution Scaler & Canvas Calculator to ensure encoding, precision, or specification version matches your target runtime.
