SAMA5D2x LCD controller

Why does the data sheet for the SAMA5D2x family of devices state
The register definition for LCD Controller Configuration Register 4 (LCDC_LCDCFG4) defines 11 bits for rows per frame and the same for pixels per line:LCD TFT controller (LCDC) up to 1024x768 or 1280x768 (still image).
Surely this gives a theoretical maximum resolution of 2048 x 2048 pixels. Is it simply the case that the performance of the LCD controller degrades the higher the resolution?Bits 26:16 – RPF[10:0] Number of Active Row Per Frame
Number of active lines in the frame. The frame height is equal to (RPF+1) lines.
Bits 10:0 – PPL[10:0] Number of Pixels Per Line
Number of pixels in the frame. The number of active pixels in the frame is equal to (PPL+1) pixels.
