Help connecting laptop to TV

  russfall63 21:29 02 Nov 2009

Hi all,

I am having problems connecting my laptop to my tv, so that I can use my tv as a 2nd monitor. Here is my set up....

The cable I am using is connected to my Compaq Presario CQ71-230SA laptops VGA port and the other end is connected to my televisions S-Video port.

The laptop I am using is Windows Vista. My tv is not HD, but does have the S-Video input. I have tried adjusting the display settings on my laptop, but still no luck.

Can anyone out there help me out with a step by step guide as to what I should do or look for?

You are trying the impossible - VGA to Svideo is a no no!

You would need at Svideo to Svideo, plus a cable for the Audio!

Sorry, having a Senior moment!! Ignore my previous post.

Is this the cable you are using click here

Yes that is the cable that I am using, the vga goes into my laptop and have a male s-video going into my tvs s-video port.

You need to check the computer user manual to make sure that your VGA card has TV output

function capability through VGA connector to ensure the S video cable will work

If the VGA card does not have TV output function capability through VGA connector you will

need a VGA to S Video converter

High Resolution VGA to Composite or S-Video Converter

Thanks for the info. My laptop did not come with a user manual, so is there any way I could check via my laptops settings to see if my vga supports tv out?

Do the following: - start – run - dxdiag

Also take a read on this forum site

Hi there,

Thanks for letting me know.

I did as you say, type dxdiag into the run menu. What I am looking for when this appears?, as I see the Display tab, but what is it that I should be looking for?

In the Display Tab page you should have the following

Left Hand Panel the Display Card Type

Right Hand Panel the Display Card Driver

Below the Direct X Feature Panel

With the following Listings

DirectDraw Acceleration: Enabled Disable Button Test DirectDraw Button

Direct3D Acceleration: Enabled Disable Button Test Direct3D Button

AGP Texture Acceleration: Enabled Disable Button

Click on the test button and let me know what you see

Sorry forget to mention you have to connect a monitor to the VGA port on the laptop before you

test the DirectDraw Acceleration & the Direct3D Acceleration

Once the monitor is connect to VGA connector you now have to set the external monitor to

show what is on the laptop screen

Using the “FN” key (Function) and the “CRT/LCD” key look at the top of keyboard “F” keys

Hold down the FN key and press the CRT/LCD key once

Display will change as follows: -

Press once laptop display only

Press again external display only

Press again both laptop and external display

You must hold down the FN key each time you press the CRT/LCD key

Depending in the size of the monitor you will have to adjust the screen resolution for the

display to fill the monitor screen

Right click on windows desktop-properties-setting and change the screen resolution to

the correct size

Thanks for that info.

I will try that tonight. Just one question, I am unsure what screen resolution to set it at. The tv I am trying to connect it to is a 42" plasma tv.

Does anyone know what resolution is best??
