Re: Howto set my NEC LCD1850E to 60hz in XF86Config-4

2004-04-26 Thread William Ballard 
The following two web pages seem to create the Modelines I want:

[1] http://www.dkfz-heidelberg.de/spec/linux/modeline/
[2] http://www.hut.fi/Misc/Electronics/faq/vga2rgb/calc.html

In particular, for [EMAIL PROTECTED], [1] generates:

# V-freq: 60.00 Hz  // h-freq: 63.73 KHz
Modeline 1280x1024 109.62  1280 1336 1472 1720  1024 1024 1026 1062 

But I have two problems with this:

1) A lot of google stuff say modelines are obsolete in Modern XFree86 - 
it will just autoselect the mode your monitor supports.  Is there a 
better way to achieve [EMAIL PROTECTED]

2) I insert the modeline into the Monitor section:
Section Monitor
[snip]
ModeLine 1280x1024 109.62  1280 1336 1472 1720  1024 1024 1026 1062

and my only Display mode is 1280x1024, but still my monitor says it is 
running at 75hz vert..

i think LCD doesn't need to follow the 1940's crt standards
of retrace and interlace or not

you should be able to read/write into video memory and not care
what the crt gun is doing in today's lcd
- it should all be autoselect based on 1280x1024 or 1024x768
that you feed the X server  ( NOT the modelines )

- or maybe todays LCD does still follow some of yesterdays slowness
- some people can see the lcd flicker... other's cant
(lcd doesnt flicker ... it's just the 60hz light and imagination)
