Note: Actual video transmission does require blanking intervals. The "Timing Format: None" option should only be used for mathematical curiosity, not to determine how much bandwidth a video signal actually needs. Even though modern non-CRT displays do not actually need blanking intervals to physically operate, these intervals have been repurposed in interfaces like HDMI for transmitting auxiliary data such as inline audio and control signals, and therefore are still required for the operation of display devices.

Can a monitor use the extra bandwidth to achieve a higher refresh rate if it doesn't send an audio signal through a DP 1.4 port? Or is it always limited to 25.92GBPS no matter what?

Audio is included in the 25.92 Gbit/s, and it takes up a pretty small amount anyway (≈1.5 Mbit/s normally)
