[G73JH] Trying to connect the laptop to my old TV to transfer audio and video<help>

i wanted to hook the laptop with my TV so i can enjoy some movies in bigger screen

so i want to connect everything- audio and video with 1 cable and without expensive adapters (the problem is i don't know which one)

my TV has in front component or composite AV in - i am not sure how it is called (yellow for the picture , white and red for the audio) and at the back it has S-video with white and red in and it has SCART also

i found this cable Wholesale VGA SVGA to S VIDEO 3 RCA CONVERTER CABLE ADAPTER Free shipping with Tracking Number #444 but how is that possible ? isn't the Vga port only transfering video ?

and the second cable that i found was this Wholesale Free Shipping&Tracking HDMI HDTV to VGA HD15 Y/Pb/Pr 3 RCA Adapter Cable N0007

i know that the HDMI port transfers audio and video

so is anything that i mentioned will help me connect it or i need something else

thanks for your help and sorry if i posted in wrong place mods can move my thread if they think it is inapropriate

 

I think a video adapter like this: For only $20.02 each when QTY 50+ purchased - VGA to RCA | S-VIDEO | VGA Converter | Analog Video Converters
...and an audio cable like this: For only $0.65 each when QTY 50+ purchased - 6ft 3.5mm Stereo Plug/2 RCA Plug Cable - Black | 3.5mm & RCA Audio Cables
...will be your cheapest/easiest route.

The cable you linked to says this: "Only certain Video cards which have TV Output function built into VGA port will work through this adapter."
I don't think our VGA ports are capable of this - but, if they are, that's cool i guess.

If you're going to be watching on an older TV, you will probably have to reduce the output resolution to 640x480.

 

so that convertor you posted will give me only picture ? for the audio i need to use the 3.5mm jack

there must be some way becouse i was able to connect my digital camera with my TV with only mini Hdmi to rca cable and i was able to watch videos i had in my camera includeed with audio

now the problem is that i couldn't use that cable to try it with my laptop becose the Hdmi port is not mini on our laptops
so maybe if i find minihdmi to Hdmi converter you think that will work ?
something like this Wholesale HDMI Male to HDMI Mini Female 1080P Adapter Connector

 

I'm guessing that your camera had a modified HDMI port where some of the pins can also serve as composite video and analog audio. If this is how it works, then when you plug in the mini HDMI-to-RCA cable, then internally the camera switches those pins to their other function.

 

i quess i will have to risk some money to find out
thanks for your answers

 

it wont do audio. i looked into it. Its a standard VGA port. Best thing to do is just get the seperate cables and tie them together.

But then again, I only use the HDMI and it works GREAT

 

as far as for the Vga port i believe it won't carry audio , althought some claim that it is possible to carry
but the laptop needs to support TV OUT and i am not sure if this laptop have this
did you checked the second link that i have posted in the first post with the HDMI cable ?

 

1. That definitely won't work.
2. VGA port only carries video, no audio. You can get audio from the headphone jack.
3. There's no way to output an S-Video or composite signal from a G73 without some sort of converter.
4. You may be in luck if your TV supports RGB SCART:

i bought the minihdmi to hdmi convertor
it is strange CCC detects the signal but disables it
any ideas ?

 

I'm surprised it actually detected something.

 

This may be something to do with the copyright protection in the HDMI standard, mite_jan. I don't know if you remember this but the television industry had a lot to do with the HDMI standard and they wanted their signal converted from digital to analog under NO circumstances. That was an attempt to close the "analog hole" in security where anything analog can be recorded onto a DVD recorder or whatever.

I think there is a hack/workaround to get the video drivers to play it anyway but I don't remember what it is. I will google and see if I can figure it out.

OK. I just researched this and the DRM I am thinking of is called Protected Media Path and it's built into Windows Vista and Windows 7. If the output is digital and protected, it won't allow it to be converted for a display unless the display has a signed driver. I'm not sure if that is your problem, but there you go.

The other suggestion I found was to shut down the computer and boot it up with the extra display plugged in already. It may be enabled when you log in. Plugging it in while the computer is already running may make it disabled but if its there at boot time it may be enabled. Catalyst drivers have that problem with some audio devices plugged into HDMI port.

Hope that helps!

 

but the DRM thing doesn't mean you can't just Mirroring your whole display right?

 

I couldn't glean enough information to figure out if it would disable everything or just the playback of protected content. I just wanted to mention it since it might be an angle worth considering before going down some other rabbit hole.

 

that's nice find Jody , i've read about people having signal only when turning the machine so i will check that out (if i get any signal then i know that there will be some way to enable it )

what about that driver you've mentioned ?

 

I found it in a couple of AMD Radeon HD manuals for desktop cards and read some more. If the output display isn't "HDCP" compliant, then the driver reduces the resolution of the output. This isn't what's happening to you.

I can't figure out why the video driver is shutting down that CRT. I think the only way you are going to get that to work is with a VGA adapter of some kind.

 

It's not anything DRM related. The Windows desktop is not DRM protected.
mite_jan is trying to connect an analog TV through a digital HDMI port, which is just impossible. So I'm REALLY surprised it even detected it.

 

yep i give up entirely from that idea
looks like i have to buy some Vga to something cable

so i have Scart convertor which looks like this


and i have Scart , svideo and RCA in the TV inputs
and on the tv there is a button which switches these modes AV , SVHS , RGB

which is my best solution here and which will give me maximum resolution and will i be able to lower the resolution on the TV properly (i believe around 500p)

since Vga port cannot carry audio then why does this cable even exist (red and white)


should this one work ? or the upper ?


and is it better to put it directly into the TV or first into the scart adapter i have mentioned that i have

damn be those old Tvs

 

None of those would work and you don't need that SCART converter. The second cable is for ancient GPUs which supported outputting S-Video and Composite signals through the VGA port. A regular VGA port doesn't do that. And I don't even have a clue for what contraption the first cable is for, but it's definitely not VGA.

Now, you mentioned your TV supports RGB, which means that your TV supports RGB signalling through the SCART port, and that's the same thing VGA uses. Had you not ignored my first post, you would have already gotten your answer and be happily using your TV.

 

lol i have not ignored your post but i was confused and still am
just give me a picture of how would look like
how can i recognise if scart uses RGB from the look of it ? or i cant becouse its inside wired

 

You can't recognize whether the SCART port uses RGB by looking at it, but since your TV says RGB, it most probably does.
You will need to make a VGA to SCART cable like described in the first link. (NOT a SCART to VGA cable because that is different and would not work).

 

Based on the inputs listed for your TV, I would use the Component Out (the 3 color analog out) and either stereo analog out (3.5mm stereo to dual RCA cable) or Toslink out if your system supports 5.1 DTS/Dolby Digital.

This would give you the best analog picture, and audio options.
