An electronic device may include a display. The display may include display driver circuitry that is configured to provide image data to columns of pixels and gate driver circuitry that is configured to provide control signals to rows of pixels. The display may be operable at a native refresh rate that is equal to the highest refresh rate at which the display has full resolution. The display may also be operable in a high refresh rate mode with a high refresh rate that is twice (or some other scaling factor greater than) the native refresh rate. To enable operation at the high refresh rate mode, vertical resolution of the display may be sacrificed. In other words, rows of pixels may be grouped together into effective rows that are then scanned in sequence. The gate driver circuitry may be formed as thin-film transistor circuitry or from gate driver integrated circuits.
