Example of Configuration
(Page 4 of 8)

Monitor Configuration



The monitor will now be configured. The horizontal and vertical sync rates must be entered. This data will be available in the documentation for the monitor, sometimes it is printed on the back of the monitor or check the manufacturer's website for the specifications.

Now we want to set the specifications of the monitor. The two critical parameters are the vertical refresh rate, which is the rate at which the the whole screen is refreshed, and most importantly the horizontal sync rate, which is the rate at which scanlines are displayed.

The valid range for horizontal sync and vertical sync should be documented in the manual of your monitor. If in doubt, check the monitor database /usr/X11R6/lib/X11/doc/Monitors to see if your monitor is there.

Press enter to continue, or ctrl-c to abort.

Now set the monitor frequencies. Pick the correct monitor sync rates and give the monitor configuration a name like was done for the mouse

You must indicate the horizontal sync range of your monitor. You can either select one of the predefined ranges below that correspond to industry-standard monitor types, or give a specific range.

It is VERY IMPORTANT that you do not specify a monitor type with a horizontal sync range that is beyond the capabilities of your monitor. If in doubt, choose a conservative setting.

hsync in kHz; monitor type with characteristic modes

1 31.5; Standard VGA, 640x480 @ 60 Hz

2 31.5 - 35.1; Super VGA, 800x600 @ 56 Hz

3 31.5, 35.5; 8514 Compatible, 1024x768 @ 87 Hz interlaced (no 800x600)

4 31.5, 35.15, 35.5; Super VGA, 1024x768 @ 87 Hz interlaced, 800x600 @ 56 Hz

5 31.5 - 37.9; Extended Super VGA, 800x600 @ 60 Hz, 640x480 @ 72 Hz

6 31.5 - 48.5; Non-Interlaced SVGA, 1024x768 @ 60 Hz, 800x600 @ 72 Hz

7 31.5 - 57.0; High Frequency SVGA, 1024x768 @ 70 Hz

8 31.5 - 64.3; Monitor that can do 1280x1024 @ 60 Hz

9 31.5 - 79.0; Monitor that can do 1280x1024 @ 74 Hz

10 31.5 - 82.0; Monitor that can do 1280x1024 @ 76 Hz

Enter your choice (1-11):

You must indicate the vertical sync range of your monitor. You can either select one of the predefined ranges below that correspond to industry- standard monitor types, or give a specific range. For interlaced modes, the number that counts is the high one (e.g. 87 Hz rather than 43 Hz).

1 50-70

2 50-90

3 50-100

4 40-150

5 Enter your own vertical sync range

Enter your choice:

1

You must now enter a few identification/description strings, namely an identifier, a vendor name, and a model name. Just pressing enter will fill in default names.

The strings are free-form, spaces are allowed.

Enter an identifier for your monitor definition: monitor1

The next display is an information screen. By answering yes to see the graphics card database, the correct driver can be selected for the installed graphics card.
