Hi,

By "Frequency" if you meant "Resolution"..check the below link,

You will have to do necessary changes in /etc/X11/XF86Config file.

Hi,

checked my monitor section in /etc/X11/XF86Config ....

Section "Monitor"
Identifier "Monitor 0"
HorizSync 30.0 - 107.0
VertRefresh 50.0 - 75.0
EndSection

This indicates U indeed can tweek frequency setting. U need reboot after the change.But be careful, wrong entries could render CDE subsystem not to start in the next reboot(can revert the change from single user mode), or worse case, could cause issues with the monitor, if the frequency setting is wrong, thereby probing the monitor with wrong frequency range. Also consult the Monitor manual's before you attempt this activity.

Hi,

I checked the monitor and it only supports 60 Mhz. when i gave setmon -r the folllwing out was displayed:
setmon -r
Using device file /dev/crt


The HPA4982B graphics device supports the following monitor entries.

Entry Width Height Hz Font Description
----- ----- ------ --- ----- --------------------
-> 1 1280 1024 75 10x20 VESA
2 1024 768 75 8x16 VESA
3 1600 1200 75 10x20 VESA
4 1600 1024 76 10x20

The current monitor selection is entry 1.


does this mean that it only supports the above configuration.

Hi,

Seeing your previous output, if you were interested in choosing the index 4, you need to specify..

#setmon -s 4 -t

-t, because, that way the setting is temperory and will be reverted beack after reboot in case you encounter any problems. Anyway , it appears though that you have only these choices to choose amonst.
