Note: Since there are several sound sources, such as the fan,
hard disk and speakers in the computer, the speakers will
scream when the volume is too high. This is caused by the
internal speakers’ positive feedbacks and can be eliminated
by decreasing the volume. When you are performing voice
recognition tasks, we recommend you to use external
microphone, because the inner sound of the computer has
certain effect to the internal microphones.
2.3 Setting display resolution
To view a program at a specific resolution, both the video controller
and display must support the program, and the necessary video
drivers must be installed.
Before you change any of the original display settings, record the
original settings for future reference. Click Start ‐> Control Panel ‐>
Appearance and Themes ‐> Change the screen resolution. Use the
slider to choose different settings for Color quality and Screen
resolution. If you choose a resolution or color palette that is higher
than what the display supports, the resolution will automatically
adjust to the closest possible setting.
