AMD/ATI Pixel Clock Patcher

[ToastyX]

It doesn't really matter what the values mean. The goal when dealing with LCD monitors is to reduce the blanking as low as the monitor and video card can handle in order to reduce the horizontal scan rate and the pixel clock. Blanking is the period between each line and each frame that isn't shown on the screen. With the Catleap 2B and Tempest OC monitors, reducing the vertical total to 1450 is the simplest most effective change you can make. It's possible to tweak it down further, but not by much.

For reference:

Front Porch + Sync Width + Back Porch = Blanking
Active + Blanking = Total

Pixel clock is the total number of pixels per second.
Horizontal Total * Vertical Total * Refresh Rate = Pixel Clock
2720 * 1450 * 120 = 473280000 (473.28 MHz)

Horizontal scan rate is the number of lines per second.
Vertical Total * Refresh Rate = Horizontal Scan Rate
1450 * 120 = 174000 (174 KHz)
