Generally you take the nearest matching mode and then modify it to match your needs. For example if you need slightly higher or lower refresh rate that is offered by the ready made settings, just try to modify the pixel clock frequency accordingly to make the mode to refresh at the rate you want.

A pixel clock is an oscillator, timing circuit or external signal that divides incoming video into pixels. The speed of the pixel clock refers to the capability of a monitor, television or computer graphics card to process pixels per second. This is expressed in megahertz or million pixels per second.
Dec 15, 2010 Can a non correct pixel clock can harm the display? For example: An hdmi splitter is connected to the pc, so several (different manufacturer) displays are connected to
Example: 1280 x 1024 @ 85Hz usually have a pixel clock of 157. 5 MHz, but how do I calculate the needed pixel clock? Need to know to select DAC and DSP. Edit: Usually the Front porch is: 16 pixels 1 line, Synch width: 144 pixels 3 lines.
A liquidcrystal display (LCD) is a flatpanel display or other electronically modulated optical device that uses the lightmodulating properties of liquid crystals. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.
The pixel clock is very stable relative to the incoming video or the picture will not be stored correctly. The higher the frequency of the pixel clock, the more pixels that will appear across the screen.
Oct 20, 2012 The pixel clock (or dot clock) is the speed at which the pixels are transmitted such that a full frame of pixels fits within one refresh cycle. For example, a VGA's dot clock set to 25MHz (corresponding to 25 million pixels per second) is just enough to display a resolution of 640x480 at 60Hz (note the active display is only a part of the frame).
A Pixel Clock setting of straight 25. 00 MHz will do fine here. Remark: The XGA2 system is an almost freeprogrammable system, but it has its limits. I would not recommend to use a pixelclock above 77MHz even though the XGA2 RAMDAC is specified to 90MHz.
