Lenovo Notebook Computer User Guide
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.
