[comp.graphics] A few quick Questions:

	A few questions:

	1)

	I have a Trident VGA chip set that is apparently
	quite capable of 640x480x256 mode (it is 512K) and
	I have a Samsung 640x480 VGA monitor. The actual code
	of the monitor is a Samsung CJ4681. I cannot however
	get my monitor to display in the 640x480x256 mode.
	Specifically I am trying to display a few gifs of this
	size using cshow, vgif, and picem; but I cannot get my
	monitor to display them. When I call up these images the
	screen starts humming loudly and doing the old tv phasing
	(scrolling up and down) real quickly. However it works on
	all other video modes. (including 640x480x16)

	My question is: Can anyone give me a clue as to how to solve
	my problem? Is it possible in my CMOS or XCMOS setup or what?
	If anyone else has had this problem with trident boards I 
	would also appreciate being let known. 

	2)

	One other question I have is: Does anyone know of a way to
	convert from a targa graphics file to a color file of almsot
	ANY other type? (except postscript) I can get my targa files
	into grayscale TIF format, but cannot find anything to convert	
	to color formats. Any info on this would be GREATLY appreciated!
	
	Thanks,
