Out of Sync Range

Out of Sync Range

Post by Darre » Wed, 31 May 2000 04:00:00



When I'm running X and I push Ctl+Alt+F2 to switch to a console
sometimes my monitor shuts off and says out of sync range.  I have the
Horizontal and Vertical ranges set right in XF86Config.  Can you set the
horizontal and vertical refreshes for the console?  Any ideas?

Thanks
Darren

It would be the lines marked "HorizSync" and "VertRefresh" and you
have to set them in the XF86Config file and restart X.

1. Monitor Sync range Versus Scan range

Greetings everyone,

Here is a dumb question for you. Is the synchronization range (Which
Redhat 4.2 claims is in our monitor's manual) the same thing as the scan
range? My manual (for Gateway 2000 Vivitron 17'')specifies the scan
frequency (31.5-80 kHz Horizontal; 50-100 Hz Vertical) but there is
nothing mentioned of synchronization.

I have tried substituting scan range for sysnc range during the setup,
but  I can not get the XFree86 (or any other X) to work. I have also
tried to extract information about synch. from the Windows 95 control
panels. But sysnch parameters appear to be a discret set of '+' or '-',
not a range of frequencies. So I am confused about what exactly is meant
by synchronization. Also I am confused on how the "refresh rates" fit
here.

I am hopping that someone who has successfully used Gateway 2000
Vivitron 17'' with RedHat 4.2 can tell me what numbers should  I put for
vertical and horizontal sync rates. In general the redhat installation
does not have an entry for this monitor, so I also appreciate getting
advice on what other parameters I should customize (chose VGA or
SuperVGA, etc.). I use the Win95 settings of 16 bit, 600x800 resolution.

Thank you very much,
Ramin Sina
