Make sure you have the PC selected on the TV.. next, i don't know the video card ( nvidia, intel) so you'll need to open whatever the video program (usually a right-click on the desktop will show the options for catalyst, or video properties) if those are not avalable depending on your operating system find video properties either in vista/7 by opening your Windows start bar and typing 'video' and finding it in the list.. else find the config section and find display propeties there...

ANYWAYS.. lol in there you hsould be able to get the options to activate the TV as either a mirrored display or an extended display.

How can i connect my laptop to my tv?


This will depend on exactly which model of laptop and TV. Look at the TV and determine what ports it has. Then look at the laptop for the same information. You may need to enable the external video ports in the BIOS. Turn off the computer and press F2 repeatedly after turning the unit on. (Some computers use Esc, F1 or F10. There will be a quick splash screen with the information.)

Then it still depends. If your TV and your laptop both have a VGA port, get a VGA M/M cable. (Often this is blue - it's a D-sub 15 pin connector.) This is the simplest option. Turn off the TV and the laptop and connect the cable. Then turn on the TV and set it to the VGA source (look for a button marked Input or Source on the TV or remote). Then turn on the computer; with most modern OS versions, it should set the correct resolution. You will need to enable the external monitor. This will depend on the OS. In Windows 7, right click on the display (where there are no running programs or icons) and select Graphics Properties. Then set the monitors to use the external monitor. Click Apply and then confirm the setting. Note: you'll need to also connect an audio patch cable (3.5 mm) between the laptop's headphone jack and the TV's VGA audio input if you want to use the TV speakers.

If your laptop and TV both have an HDMI port, you may be able to use that cable. You'll need to check the details on the TV. Not all TVs will read the computer's signal on the HDMI port. (The data isn't the same as from a set-top box like a Blue-ray player or cable box.)

If the laptop has a DVI port, depending on the TV, try either a VGA to DVI adapter or a DVI to HDMI adapter.

A few older laptops may have have an TV out (looks like S-video) port. In that case, you can connect to a similar port on the TV with a dongle and the cables.

For a TV with only composite or component input and a laptop without a TV out option, you'll need a VGA to composite or a VGA to component converter. These convert the RGB signal from the laptop to one that the TV will understand (component is YPbPr). See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-composite-video/c10000-c11200-c11213.html?sorter=productname-en-asc or http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc for examples.

Please add more information about your laptop and TV for additional help.

Link ASUS laptop to Sharp Aquos LCD TV


No, a DVI to VGA adapter will not work. (The TV is looking for the digital signal from a set top box. This is different from the analog signal on the VGA cable.) You need a converter. Your best bet would be a VGA to component video converter. (I am assuming that the Sharp TV has a component video input.) This page has some examples: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215.html?sorter=productname-en-asc . Note a VGA to component video cable will not work. The VGA to component cables are for projectors that read the RGB signal. The component video signal is YPbPr.

Connect the VGA cable to the converter and the component video cable to the TV and the converter with the computer and TV off. Turn on the TV first and set it to the component video input and then turn on the computer. Then (assuming the VGA port is enabled - adjust in the BIOS if needed) set the computer's video output to the VGA port. (On my Windows 7 laptop, this can be done by right-clicking on the desktop. Choose Graphics Properties and set the display to the external monitor or both. Click Apply and then confirm the change (on the external monitor if using the single monitor). (VGA to Composite video converters also exist if you do not have an available component video input on your TV.)

If your computer is fairly new, you may have an HDMI port. Your TV may be able to read the signal with a DVI to HDMI cable. (It depends on the TV. Not all of them will read the computer's signal on the DVI port. Check the documentation for your model. TVs without a VGA port are less likely to support this feature.)

I hope this helps.

I just want to know what kind of cable I need to connect my LTV-37w2HD TV to my computer?@highes.net


The video cable should be a VGA cable, assuming your computer has a VGA connector. Get one that has M/M ends. This is sometimes listed as a 15 pin D-sub connection. Then connect a 3.5 mm audio patch cord (m/m) between the audio out (speaker/headphone) pf the computer to the TV's VGA audio in (if you want to use the TV speakers).

If your computer has an HDMI or DVI output, I do not believe that you can connect to the TVs HDMI port. (The signal from the computer is not the same as that from a set top box.) If you have a DVI port, get a DVI to VGA adapter and then connect to the VGA cable. (You could use a DVI-DVI cable and then the DVI to VGA adapter at the TV. However, space is an issue at the TV.)

Make sure that the VGA port is enabled on the computer. (Some newer computers have a different video port enabled initially.) This may require entering your BIOS just after turning on the computer. Usually you need to strike Esc, F1 or F2 repeatedly starting when you press the power button. (F10 is also a BIOS access with some manufacturers - the key will be listed in a splash screen that is only visible for a few seconds.)

With the computer and the TV off, connect the cables. Then turn on the TV and set the input to VGA. Next turn on the computer. (If this is the only monitor attached, the computer should find the correct resolution (Windows). If you are using a dual monitor option, then you may have to enable the TV as a monitor. This will depend on the OS. For my Windows 7 laptop, it's right click on the desktop and choose Graphics Properties. Set the monitor options for both, external or attached and click Apply. Then click OK when a confirmation window appears. With my Windows 7 desktop, it's right click on the desktop and choose Screen Resolution. Similarly choose the settings, click Apply then OK to confirm.)

I hope this helps.

How do I connect my laptop to tv to use as monitor


It depends on the laptop and the TV. If both have a VGA port, then use a VGA cable between them. Make sure the VGA port is enabled on the computer (possibly in the BIOS) and then set the monitor properties. You may need to reboot the computer to get the TV on.

If the TV has HDMI input and the laptop also has an HDMI port then you need to check the TV specs. Some HDMI ports can accept a signal from a computer (often labeled HDMI/DVI) and others don't. If the HDMI port is compatible with a computer source, then use an HDMI cable between the two. Again make sure the port is active. If TV's HDMI port is not compatible with the computer, you will need a converter.

If the TV doesn't have a VGA port (and the laptop doesn't have any video port other than VGA), then you will need a VGA to component video converter (or VGA to composite video) depending on the inputs of the TV. See http://www.svideo.com/pctocomponent.html for some converters.

Note: the converters are needed since computers output in a different format than the TV input understands. For analog, the computer is RGB and the component video is YPbPr.

A few media PCs might have a TV out port. This would eliminate the need for a converter. Check the specs for the cable you need.

I hope this helps.

How to conect my laptop to LCD


It depends on the laptop connections. First make sure that your computer is sending data to the port (particularly VGA); you may have to access the BIOS to change the setting (often F1 or F2 on restart). If you have a VGA port on the laptop, get a video cable (VGA-VGA) and connect the two together (this is usually a blue port and you need M/M ends). Then enable in the graphics properties (right click on the display where there are no icons or running program). You want the section that lets you choose sending to the external monitor, the laptop monitor or showing the same contents on both. The version of your OS may alter which command you need (you can also access this in the Control Panel (Display). You may need to restart the computer with the TV on to get the computer to recognize the TV. Set the TV to have the source the PC input. Also connect the speaker cable from the laptop to the TV if you want to use the TV's speakers (there is an audio port next to the VGA port that I believe is a 3.5 mm jack (would need a stereo 3.5 mm m/m cable between the two). Make sure you select the optimum resolution of 1360 x 768.

If you have an HDMI port on the laptop (newer laptops), get an HDMI cable (m/m) and connect the two. Set the TV to DVI or HDMI source (depending on if you need the audio cables separate) and reboot the computer. Then enable the display, as above. I believe you still need the audio cable as well (should use a 3.5 mm stereo to RCA R/L (red/white) cable) look for the DVI audio next to the HDMI/DVI port.

I hope this helps.

(my understanding is that computer HDMI ports do not send the audio but you should check your laptop manual.)

I want to connect my Thinkpad T30 laptop to HDTV


Depends on what connections are on your laptop and tv check them both. If you have a HDMI port on both you can use that. If not most recent TV's have a VGA port which you can use using a standard vga cable if not they will have a DVI or S-Video port and you will need one of those cables which are all availble from any computer shop. But check which one you need first

I have just bought an acer aspire 7720g laptop and i want to connect it to my 50" lg plasma tv, can you help


If your TV has a VGA input, you can use a regular VGA cable from the computer's external VGA connector.

If the set doesn't have a VGA input, you can get an adapter cable (here's one) to go from the computer to the TV's component video input.

You might have to enable the computer's external monitor from the keyboard. One of the function keys usually does this, see your computer manual.

*Yes you can: If your TV has either an S-Video input, or a VGA Input.

If it does not, then you wouldn't be able to without an S-Video-to-Component Converter. (very cheap though, if you buy one, you would use the same procedure For S-video below.

But if it does,

  • FOR S-Video Output: You would have to go into your control panel for your integrated graphics card, or graphics settings, and find where it enables you to use S-Video Output.
  • Then you would have to set the source of your TV to "S-Video" of course you also need an S-video cable to connect your TV to the input on the back of your computer, and an audio cable with a standard Stereo (3.5mm) headphone tip on one end, and standard Left/Right audio component tips on the other end. You'd Connect the stereo end of the cord into your headphone jack on the computer, and the other end with Left/right ends (usually white/red, or black/red) in to the input on the TV. (the audio input on the TV should be directly associated with, or by the s-video input jack).
  • FOR VGA Output: You would need to connect a VGA Cable to your computer, and to the VGA Input on the TV. For VGA
  • "To enable VGA out most laptops will have a keystroke such as Function-Key+F8 "Fn + F8" to enable the second display.. Look for a key that says "CRT/LCD" (the link is to an image of the key.)
  • So, [Fn + CRT/LCD]

    Most popular:
    Fn + F8
    Fn + F7
    Fn + F4
I Hope This Helps.
(Sorry for the extra long response....)
Give a shout back if you have any more questions, and I'll be Glad to assist you further.
