MONITORS LAB
Name _________________________________________
Date _____________________
This lab will focus on your ability to accomplish the following tasks:
• Change the screen resolution
• Change the color depth
• Change the refresh rate
• Check power settings
Before you begin, the Instructor will have a typical PC available. The desktop policies must be set to allow
access to the Display icon in control panel. The following resources will be required:
1. PC workstation with monitor, keyboard, mouse, and power cords
2. Windows operating system (Windows 9x or XP) installed on PC
Step 1 – Boot (start) the PC and log on.
Step 2 – Use the Control Panel / Display to change the monitor’s display settings (This may also be
accomplished by right clicking the desktop and select Properties)
• Select the Setting tab. Record your findings in the table below:
Current Display
Current Resolution
Current Color Depth
What screen resolutions are
available?
What color depths are
available?
•
Change the screen resolutions. How does it effect the display?
•
Change the color depth. How does it effect the display?
•
Reset the resolution and color depth back to their original settings.
Step 3 – Select the Advanced button to see more options.

Step 5 – Check the monitors power settings by clicking on the Screen Savers tab.
• Is the computer Energy Star Compliant?
• If you see the Energy Star Logo and the Power button is enabled, then the computer is energy
Star Compliant. The Energy Star label, a symbol for energy efficiency, was created by the U.S.
Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) to help
customers identify products that can save them money and protect the environment by saving
energy. An ENERGY STAR qualified monitor, in sleep mode, uses 90% less electricity than
monitors without power management features.
• Click on the power button. Record information about the current power setting scheme:

SAMPLE MONITORS LAB:
This lab will focus on your ability to accomplish the following tasks:
• Use the WINIPCFG.EXE utility with Windows 9x or IPCONFIG.EXE utility with Windows XP to
determine network settings
• Determine the Computer name and Domain name
• Determine the NIC manufacturer and driver
• Identify what network (layer 3) protocols are bound to the NIC (in use)
• Determine the Internet Protocol (IP) layer 3 address
• Determine the subnet mask and IP address of the default gateway (router)
• Determine whether Domain Name System (DNS) , Dynamic Host Configuration Protocol (DHCP)
and Windows Internet Name Service (WINS) are being used and the IP addresses of the servers
providing these services
• Determine the Media Access Control (MAC) or hardware address of the workstation NIC
Before you begin, the Instructor will have a typical PC available. The desktop policies must be set to allow
access to the Network icon in control panel and either the Run Command or the DOS Command Prompt
in order to run the WINIPCFG and IPCONFIG utilities. The following resources will be required:
1. PC workstation with monitor, keyboard, mouse, and power cords
2. Windows operating system (Windows 9x or XP) installed on PC
3. NIC installed and Cat 5 patch cable with connection to the Internet
Windows 9x (use this procedure if you are using a Windows 9x machine)
Step 1 – Boot (start) the PC and log in to the network.
Step 2 – Use Control Panel / Network to determine the Workstation Computer name, Domain name,
Network Client, the network layer 3 protocols in use, and information about the NIC. (You may also right
click Network Neighborhood and select Properties)
• Click the Identification Tab at the top of the window to find the Computer name and the Workgroup.
• Click the Configuration Tab and note what networking components are installed. The Network Client
has an icon that looks like a computer, the NIC icon looks like a NIC and the Protocols have an
icon that looks like a network cable connection. There may be more than one of each of these.
Record your findings in the table below.
Component (NetBIOS) Name
NT Domain Name
Network Client Type
NIC installed (driver name)
1st Protocol installed
2nd Protocol installed
Other network components
Other network components
Step 3 – Check the TCP/IP related settings such IP address information, DHCP and DNS.
• Click on the TCP/IP protocol while on the Network Configuration Tab and then click Properties. Click
on the Tab indicated in the table and record your findings below.

Step – 4 Using WINIPCFG.EXE utility
• You can run WINIPCFG.EXE from the Start / Run command or from the DOS command prompt. (If
you enter WINIPCFG /ALL from the command line (be sure to put a space between WINIPCFG
and /ALL) you will get much more information.)
• Be sure to select the proper NIC or Ethernet adapter (this will be in a pull-down box). Record your
findings in the table below.
Workstation IP Address
Workstation Subnet Mask
Workstation MAC Address
Default Gateway (Router)
DHCP Server
DNS Server IP Address
WINS Server IP Address
Windows XP (use this procedure if you are using a Windows XP machine)
Step 1 – Boot (start) the PC and log in to the network. Be sure you have administrative rights to view the
TCP/IP settings.
Step 2 – Use Control Panel / System to determine the Workstation Computer name and
Workgroup/Domain name. (You may also right click My Computer and select Properties)
• Click the Identification Tab at the top of the window to find the Computer name and the
Workgroup/Domain name.
• Click the Configuration Tab and note what networking components are installed. The Network Client
has an icon that looks like a computer, the NIC icon looks like a NIC and the Protocols have an
icon that looks like a network cable connection. There may be more than one of each of these.
