config FB_I810_GTF

	depends on FB_I810
	help
	  If you say Y, then the VESA standard, Generalized Timing Formula 
          or GTF, will be used to calculate the required video timing values
	  per video mode.  Since the GTF allows nondiscrete timings 
          (nondiscrete being a range of values as opposed to discrete being a
          set of values), you'll be able to use any combination of horizontal 
	  and vertical resolutions, and vertical refresh rates without having
	  to specify your own timing parameters.  This is especially useful
	  to maximize the performance of an aging display, or if you just 
          have a display with nonstandard dimensions. A VESA compliant 
	  monitor is recommended, but can still work with non-compliant ones.
	  If you need or want this, then select this option. The timings may 
	  not be compliant with Intel's recommended values. Use at your own 
	  risk.

          If you say N, the driver will revert to discrete video timings 
	  using a set recommended by Intel in their documentation.
  
          If unsure, say N.

	  "Matrox I2C support" and "G400 second head support" here in the
	  framebuffer section. G450/G550 secondary head and digital output
	  are supported without additional modules.

	  The driver starts in monitor mode. You must use the matroxset tool 
	  (available at <ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/>) to 
	  swap primary and secondary head outputs, or to change output mode.  
	  Secondary head driver always start in 640x480 resolution and you 
	  must use fbset to change it.

	  Do not forget that second head supports only 16 and 32 bpp
	  packed pixels, so it is a good idea to compile them into the kernel
	  too. You can use only some font widths, as the driver uses generic
	  painting procedures (the secondary head does not use acceleration
	  engine).

	  G450/G550 hardware can display TV picture only from secondary CRTC,
	  and it performs no scaling, so picture must have 525 or 625 lines.
