Redirect Laptop output to SD TV

Hello
I want to display of my HP notebook ( dv9700t) to my Philips/magnavox 25TS56-C221-Standard TV


My notebook has
Windows Vista 32 bit operating system
VGA card-NVidia GeForce 8600GS -512MB - (I am not sure how to find out if this vga card supports TV out signal)
7-pin S-Video output
VGA output

My TV has
A/V port - Red,Yellow and White

i have tried following cables but not sucessfull. I try to change the frequency and resoultion from my laptop.
(i.e 50Hz and 1000x600 etc )

I have attached the pic of cable that i tried.

1)15pin VGA SVGA to 3RCA AV Audio Video M/M Cable Adapter

2)N VGA SVGA to RCA S-Video AV TV Adapter Converter Cable
( http://www.1powershop.com/en/comput...ca-s-video-av-tv-adapter-converter-cable.html)

Let me know if it is doable or not or i need to do something extra.

The easiest way is to go direct S-video to a S-video input on your TV.

Unfortunately - on a 'standard' definition 4:3 TV - you are going to get really poor quality video.

 

Like the above poster said, the best way is S-video to S-video or S-video to composite.

 

Thanks for reply. My tv does not have s-video input. i have tried N VGA SVGA to RCA S-Video AV TV Adapter Converter Cable- but no success.
i am not sure if i can get cable - that has -at one end s-video mail and other hand red,while and yellow male cable.

I have Geforce 8600 GS vga card in laptop. i am unable to find specification.

 

Of course you won't find an S-video to the Red-White-Yellow cable. Red and White are used for sound, while S-video doesn't carry sound. You just need an S-video to composite video (aka, just S-video to yellow).

 

Thanks agian. Same i used also. you can see the attached pic which i have used on my first post.
Seem i cant do anything.

 

No. The pictures show a VGA to component and VGA to S-video/composite. You need S-video to composite.

I'm trying to do the same thing. I have tried an S-video to composite (yellow RCA) adapter from Best Buy but it didn't work. I am now going to order the one at the link below and see if I have better luck!

I do this all the time with my DV6000T, and there are two ways of getting it to work -- with a number of ways to mess things up along the way.

Both methods start by connecting your S-video out to your TV's composite or S-video in. Make sure you turn on your TV first and set it to your appropriate video in channel. This will help the computer to "find" the TV and adjust to it like a plug-and-play device.

NB: you should be able to do this with your laptop on and running, but to be on the safe side (i.e., to guarantee it works) I recommend hooking everything up with your computer off, then turning on your TV, then your laptop.

Then you have two choices:

Method A: using either your HP remote (the |O| button) or the keyboard (fn + F4 keys), toggle between laptop LCD > TV > TV + LCD > back to LCD settings. This should auto-detect your TV and rescale your display resolution appropriately. Just press the toggle until you see what you want on your TV. If nothing ever comes up on your TV, keep clicking until your LCD is back to its normal resolution, then try:

Method B: with everything hooked up, right-click your screen to bring up Personalize > Display Settings. Click on Monitor 2, check "extend my desktop to this monitor", set the display resolution (on monitor 2) to 1024x768 or less (very important -- this method does not auto-detect the screen resolution, though the refresh frequency should be fine), then click Apply. You should see something on your TV now. If you want to use only the TV, check "make this my primary monitor", then go to Monitor 1 and uncheck the "extend" box, then hit Apply again -- but don't do this until you've confirmed that your laptop will extend onto the TV, or you will have problems.

One of these methods should have worked. If it didn't, turn the laptop off follow the startup procedure above (first start the TV, then the laptop) and try one of these methods again. Whenever the switchover doesn't work right off the bat for me (which is like half the time), I can always get it to work by restarting the laptop with the TV plugged in and on.

If it still doesn't work, make sure you have the latest video driver for your machine from HP -- sometimes the laptopvideo2go and other drivers are not fully compatible with your laptop's S-video out.

Also, I have that exact same Cables-to-Go cable mentioned above (from Amazon), and like it quite a bit. But I've gotten lots of different s-video to composite adapters to work for me -- although I've never tried VGA to composite.

Hope this helps...

 

Thanks a lot for the guide. This should be a sticky!

I have tried both your methods and didn't have luck with either of them. The only time I got something to sort of work was get it running on an s-video cable and then switch to the adapter. And then, I only got black and white.

I have the laptopvideo2go drivers so that might be the problem. I'll try swapping them with the HP drivers tonight as I didn't see much of an improvement with the 3rd party drivers anyway. I'll probably still order the cable because it's nice to have the sound and video all in one!

 

Thanks!

There's a third way of getting your display onto an external monitor/TV, which I had forgotten about earlier. It involves using the Nvidia Control Panel, which you should be able to bring up from the Control Panel, or by right-clicking the screen. Here's how:

Step One, before doing anything else, plug your laptop into your TV and turn the TV on. You should be able to do this with the laptop already on. Then start the Nvidia Control Panel -- your computer should recognize the external monitor at this point. From the left-hand menu, go to Display > Set up multiple displays (you may need to use the Advanced View to see it).

Here you should be able to see a graphic representing your screen and your TV, plus some choices (if not, something is wrong). I recommend, for a test, that you select "Configured independently from each other (Dualview)". The LCD + TV configuration should pop up automatically on #2 (if not, select it from the pulldown), and keep the laptop as primary. Hit Apply. This configuration is a desktop extension, not a clone, but if it works, then you can change #1 to Clone or Single as needed. (Note that Clone or Single will rescale your main LCD to 1024x768.) I recommend trying out Clone before Single, but if you lose all your displays you can just wait 15 seconds and everything should come back to normal.

if you're using HP's latest video driver, you can also change the resolution for your TV from the Nvidia Control Panel (under Display > Change Resolution), which is convenient. Only the most recent HP video driver supports this, so make sure you have it!

Now if you've tried all three methods and are still faced with a black TV screen, then one (or more) of the following may be true:

You didn't follow my instructions. Is the TV already on and tuned to the appropriate video input (Video 1, Video 2, etc.)? Did you do this before you tried to open any settings windows? Did you go back and try restarting the computer with the TV already on? Did you rescale everything to 1024x768? (As an aside, some HDTVs will actually require you to rescale to a resolution higher than your system default, making true cloning impossible, though these TVs will usually also support a really bad looking 1024x768).

Your video driver is bad. I've personally had problems getting laptopvideo2go drivers to work with the S-video out, and as a result, I've sworn them off altogether. Those drivers are designed mainly to play video games on your main screen, as opposed to anything else. HP's most recent Nvidia driver (called v2.00A for some reason, but really it's the 167.43 driver) works admirably with external TVs/monitors.

Your cable is shot. It happens that s-video to composite adapters will get bent or otherwise develop a short. Try a different one before giving up in disgust. I recommend the 12-foot adapter from Cables-to-Go, as it involves one less connection than the typical "adapter and cable" method. Of course, this one may not be ideal if you're planning to run your audio out into a separate place like a stereo receive. In that case, you'll need a second red and white Y-cable.

Strange things are happening. Getting the s-video out to work consistently has been the... shall we say... least scientific aspect of my computing experience. By that I mean, one day I'll fire up the computer, plug in the TV, hit the remote, and everything works like a charm. The next day, same thing, no dice. Then I'll open the Display Properties and see that my computer suddenly thinks my same-old TV now supports a resolution of 2560x2048 or something, and I'll fix it there and it'll work again. If that doesn't work, a restart with the TV plugged in and on usually clears everything up.

Be aware, though, that sometimes changing TV-out methods/signals carries the possibility of screwing things up. One time, I was running S-video out to S-video in, then I went back to my LCD, changed the wires, and tried to run S-video to composite in on the same TV and it didn't work until after I restarted. The same thing can happen if I try to go from running a VGA-to-VGA connection to an S-video to composite, too, without restarting.

In other words, when you're tyring to hook up your TV to your laptop, don't forget the First Rule of Windows: when in doubt, restart. It's good for Vista too...

Hope this helps!

 

Just to follow up on this thread. I was able to get my S-video to composite adapter to finally work. Turns out it was the laptop2go video drivers causing the problem. As soon as I loaded the genuine HP drivers and followed the excellent instructions in this thread the video turned on.

Thanks to everyone for their help!
