How to Connect a Samsung DLP & a Dell Laptop

by Jeff Grundy Google

    Digital Light Processing televisions use rear projection mirrors, technology that's generally much less expensive to produce than that found in LCD, LED or plasma televisions. Consequently, Samsung and other TV manufacturers can often sell a 60- or 70-inch DLP TV for about the same cost as a LCD, LED or plasma model with a small screen. Like other modern TVs, you can connect a Samsung DLP TV to computer and use it as an external display. Therefore, if you would like to view games, videos or other applications on a Dell laptop in a larger format, you can connect the notebook to the Samsung TV and use the TV as an external monitor.

    Step 1

    Select a VGA, DVI or HDMI cable for connecting your Dell laptop and Samsung DLP TV. Choose the interface supported by your laptop that offers the highest resolution and bandwidth. If your Dell has an HDMI port, use it to connect the notebook to the TV, as it's the easiest connection method and does not require that you use a separate audio cable set for sound - HDMI carries audio and video signal over the same cable. DVI does not support audio on a single cable but can display HD resolutions similar to those delivered by HDMI connections. On older Dell laptops, VGA is your only choice.

    Step 2

    Power off your Dell laptop and Samsung DLP TV. Connect one end of the video cable to the appropriate video-out port on the laptop. Connect the opposite end of the video cable to the matching DVI, HDMI or VGA port on the Samsung DLP TV. When connecting the cable to the television, note the port name used -- i.e., DVI or VGA.

    Step 3

    Locate the "Headphone" jack on your Dell laptop. It should be on the side or front of the base of the laptop. After you locate the jack, connect the small plug on the 3.5mm-to-RCA audio adapter cable to it. Connect the red-and-white RCA connectors on the audio cable to the "Audio In" ports on the rear of the Samsung DLP TV. When connecting the cable to the TV, just match the colors on cable connector with those of the female ports. If you're using an HDMI cable to connect the Dell laptop and Samsung TV, you don’t need to connect an audio cable.

    Step 4

    Power on the Samsung TV first, then the Dell laptop. Press the "Input" button on the Samsung remote until the label of the port use to connect the DLP TV to the Dell laptop appears on the television screen. For example, if you connect the notebook to the VGA port on the DLP TV, press the "Input" button until "VGA" appears at the top of the Samsung television screen. Wait a few seconds for the Dell laptop to boot into Windows. Log in with your Windows username and password if necessary.

    Step 5

    Press the "Windows" key, then click "Control Panel." Click "Display," then "Change Display Settings." In the Screen Resolution window, click the image of the monitor with the number "2" label. If only one monitor image appears in the Change the Appearance of Your Displays box, click "Detect" and wait a second or two for the screen to refresh and display two monitor images - one with "1" and the other with "2." After the screen displays both monitor images, you can the select the one with the "2" label.

    Step 6

    Click the drop-down list labeled "Duplicate These Displays" next to the Multiple Displays label, then select the "Extend These Displays" option. Click the "Apply" button, then "OK" to save the display settings and close the Screen Resolution window. After closing the Screen Resolution window, a new Windows desktop screen appears on the Samsung DLP TV.

    Step 7

    Launch a new program window on the Dell laptop, such as a media-player application or a game. Click and hold the title bar at the top of the window, then drag the window to the right until it appears on the Samsung TV. Use your mouse to perform actions in the window on the Samsung TV as you normally would.


    • With some older Dell laptops, you may have to press the "Fn-F8" keys before the notebook screen displays on the Samsung TV.
    • VGA ports are blue, DVI connectors are white and HDMI slots resemble large USB ports. DVI and VGA ports should be on the rear of the laptop, while HDMI connectors may be on the side or the rear of the notebook.
