Display Settings

Virtual Desktop

     The virtual desktop feature allows you to set up a screen area larger than your actual screen size. In other words, your work space extends beyond the edges of your physical screen, giving you a larger desktop work area. You can scroll up, down, left, and right on this virtual desktop by moving your mouse to the edge of the screen causing the non-displayed extension of the screen to come into view.

    The Virtual Desktop display at the upper left-hand corner of the Display Settings menu provides both information and control ON/OFF switch.

     The information provided is a pictorial representation of the memory allocation and the virtual desktop arrangement. The gray area represents the display screen, or viewport. The dark blue area represents the virtual desktop, or the amount of work space available beyond the display screen size. The light blue area represents the portion of system memory that is available for graphics. The red area represents the portion of system memory that is not available for graphics. Selecting any of the colored Info buttons displays an informational message defining what the correspondingly colored area represents.

     For control, the On/Off switch allows you to turn the virtual desktop on and off. Position the cursor inside the rectangle containing the on/off button and click the left mouse button once to toggles the virtual desktop on and off. When the virtual desktop is on, you can establish its size in either of two ways: (1) with the left mouse button, grab the edge of  the virtual desktop on the display representation (dark blue when the virtual desktop is larger than the viewport, or gray when they are the same size), and then drag it to the size you want, or (2) select one of the default settings under the Virtual Desktop selections at the right of the Display Settings menu screen. The virtual desktop size, which includes the size of the actual screen, is always shown in this section of the display; it defines the size in pixels (for example, 800x600 represents a virtual desktop 800 pixels wide and 600 pixels high).  If the actual screen resolution (viewport) is smaller than the virtual desktop, the gray area represents the viewport and the dark blue area represents the virtual desktop. The virtual desktop cannot be smaller than the viewport.

Total Memory

     The Total Memory selection defines the apportionment of memory between system and graphics. To change memory apportionment, either: (1) hold the left mouse button down over the center slide button and slide it left or right to select the memory apportionment, or (2) click on the left arrow to increase system memory size or the right arrow to increase graphics memory size.

To obtain the most efficient apportionment of memory for your configuration, we recommend that you:

1. Move the slide bar all the way to the right.

2. Select the color depth, resolution, and virtual desktop settings you want to use.

Note: There is a tradeoff among these settings; increasing one limits the selections that can be made for the others. Consequently, you have to adjust the three of them to obtain the most efficient balance for your purposes.

3. Move the total memory slide bar as far to the left as it will go.

Color Depth

     When you click the left mouse button once on the down-arrow button next to the Color Depth selection, the configuration utility displays the available color depth selections: 8 bpp (256 colors), 16 bpp (64K colors), and 24 bpp (16.8M colors). Click once on the color depth you want to use. Any selection that is gray is not available because not enough graphics memory is apportioned to support it in combination with the currently selected virtual desktop setting and the resolution; the combination of virtual desktop, color depth, and resolution determines the amount of graphics memory required. (This is why we recommend that you select the maximum amount of graphics memory before selecting the virtual  memory, color depth, and resolution, and then reduce the graphics memory to the amount required to support your selections. Then, if you then want more system memory, you must reduce one or more of these settings.)

Resolution

     When you click the left mouse button once on the down-arrow button next to the Resolution selection, the configuration utility displays the available resolution selections: 640x480, 800x600, 1024x768, and 1280x1024. Click once on the resolution you want to use. Any selection that is gray is not available for either of two reasons: (1) not enough graphics memory is apportioned to support it in combination with the currently selected virtual desktop setting and the color depth, or (2) the resolution is not available with the currently selected color depth (not all resolutions are available with all color depths, as shown by the summary of valid combinations in table below).

Resolution	Color Depths

   640x480	8, 16, 24

   800x600	8, 16, 24

 1024x768	8, 16

1280x1024	8

Virtual Desktop Size

     When the virtual desktop is off, the virtual desktop size displayed is always equal to the viewport size (the selected screen resolution) and the configuration utility displays the virtual desktop size in gray to show that its selection is currently unavailable. When the virtual desktop is on and you click the left mouse button once on the down-arrow button next to the Virtual Desktop selection at the right of the menu, the configuration utility displays a list of virtual desktop sizes. Click on the up and down arrow buttons to scroll up and down in this list. Click once on a choice to select it. If you want a size other than those displayed, change the virtual desktop size by resizing the pictorial representation, as described in the Virtual Desktop paragraph. If you select a size that is too large to be supported by the memory available for graphics, or if  you select a size smaller than the viewport, the configuration utility displays an error message; after reading the error message, click on OK and then select another virtual desktop size or reconfigure the system to allow specification of the size you want.

Font Size

     When you click the left mouse button once on the down-arrow button next to the Font Size selection, the configuration utility displays the available font sizes: Small Font and Large Font. Click once on the font size you want to use. If the Large Font selection is gray (unavailable), you must install the 8514 fonts from your Microsoft Windows diskettes if you want to use large fonts. To do so:

** To install the 8514 fonts:

1. Launch the Control Panel.

2. Select "Fonts", the Font installation utility.

3. Install the following fonts (the filenames should match, but the descriptive names may vary slightly):

     Descriptive name                                               	Font filename

     -----------------------------------------------------------------------------------

     Fixedsys for the IBM 8514                              	8514FIX.FON

     System (Set #6)                                                 	8514SYS.FON

     Terminal Font for the IBM 8514                      	8514OEM.FON

     Small Fonts (8514/a res)                                 	SMALLF.FON

     Courier 10,12,15 (8514/a res) 	COURF.FON

     MS Serif 8,10,12,14,18,24 (8514 res)               	SERIFF.FON

     MS Sans Serif 8,10,12,14,18,24 (8514 res)      	SSERIFF.FON

     Symbol 8,10,12,14,18,24 (8514/a RES)            	SYMBOLF.FON

4.  Once you have properly installed these fonts, you can use  the W464 Configuration Utility (the Control Panel applet  "W464 Display") to select Font Size = Large Font.  The  W464 Configuration Utility will update your SYSTEM.INI as needed to use the 8514 "large" fonts.

5. Edit the system.ini file in your Windows directory to change the entries shown below to the values shown below:

     Change following lines in SYSTEM.INI file if you plan to use small fonts.

   [display]

   dpi=96

   [boot]

   oemfonts.fon=vgaoem.fon

   fixfont.fon=vgafix.fon

   fonts.fon=vgasys.fon

   [boot.description]

   aspect=100,96,96

 Change following lines in SYSTEM.INI file if you plan to use large fonts.

   [display]

   dpi=120

   [boot]

   oemfonts.fon=8514oem.fon

   fixfont.fon=8514fix.fon

   fonts.fon=8514sys.fon

   [boot.description]

   aspect=120,100,100

6. Save the changes and close the file.

7. Restart the system.

Both large and small fonts are now available when you restart Windows and reenter the configuration utility. When you restart Windows, large fonts will be selected. To return to small fonts:

1. Select small fonts with the configuration utility.

2. Restart the system and Windows.

Refresh Rate

     When you click the left mouse button once on the down-arrow button next to the Refresh Rate selection, the configuration utility displays the available refresh rates. Click once on the refresh rate that is appropriate for your monitor and the work you intend to do.
