MORE INFORMATION

Toshiba provides this screen utility for its laptop gas plasma displays. XCHAD provides brightness and contrast control for the Toshiba gas plasma display. By creating a batch file or putting an XCHAD.EXE command in the AUTOEXEC.BAT file, the screen contrast can be greatly enhanced.

The XCHAD.EXE program is on the Toshiba Diagnostics and Supplemental disk you receive with the Toshiba DOS disks.

Creating a Batch File

Using Windows Notepad or another text editor, create the following batch file and save it in your WINDOWS directory as WINPLSMA.BAT.
```
      XCHAD 0,1,2,3,0,1,2,3,0,1,2,3,0,1,2,3 /M10

```

Exit Windows and start it again using WINPLSMA.BAT.

You may also improve the video display contrast by setting the Color Schemes to Fluorescent under Color from the Control Panel settings.
