It's possible that your computer will output y-pb-pr. If not, you will need some type of vga->y-pb-pr converter, such as this one.
(please note: i'm not endorsing this particular product in any way! It's just an example of what you will probably need if your computer doesn't output y-pb-pr signal through it's vga port)

thanks for the reply maitland. yes i was refering to the colors because i thought thats the name of the cable. i know rca are the yellow red white. what about an adapter from vga to dvi? will this work also. vga is analog and dvi is digital, will the adapter convert it??? they sound like stupid questions, but i'm very technically illiterate ,lol

I understand vga to hdmi isn't possible with just a cable.. I bought one from ebay from china or korea or whatever and It's useless It did not work whatsoever so here is my delima maybe someone can help me I would like to connect my pc to my tv
my pc is a Dell Inspiron 530s (S) meaning slim and takes a low profile video card if an update is necessary and it has integrated vga
my tv is a philips 1080p hd 42" lcd with hdmi composite rca inputs any suggestions short of spending 200 dollars on a converter box?

@chewman
usually dvi outputs carry both analog and digital signals. Therefore, you can usually connect a dvi output to an hdmi (digital) OR a VGA (analog) input.
I've never tried connecting a VGA output to a dvi input, but I figure it prolly doesn't work.
You didn't say your teevee had a dvi input, anyway, correct?

maitland - Apologies, looks like i made a mistake. In 5 years here i've never even heard of MP3Lizard, not my bag so to speak. I'll leave the thread in peace.

Hi guys,
I have a PC with a Geforce 6800 xt graphics card with a dvi output. I have just purchased a LG Lh5000 37inch lcd tv and this has the VGA connection as well as the RCA (red, white & yellow cable connection) and HDMI connections.
I simply want to know which one of the connection metods would give me the best picture on my TV. I have a Blu-ray writer/player in my PC & want to watch blu-ray movies connected to my LCD TV so which connection will give me the best picture?
Regards, Shuja
Thanks,
Shuja Ahmad

Thanks INFEST, that converter does sound useful.
BUT i still don't have an answer to my question of which is the best connection to use from a PC to LCD tv.
I have a geforce 6800 xt graphics card with dvi output plus the s-video splitter output and i have a LG LH5000 lcd tv which has hdmi, vga, component & RCA connections.
So which of these would be the best for picture quality &getting full HD content viewable from pc to TV?
I have tried the DVI to HDMI cable & this looked pretty good. I don't want to go around and spend money on all the cable combinations possible to connect my pc to my tv so your advice would be useful. So is DVI to HDMI the best picture quality connection for my pc-tv?
Thanks,
Shuja Ahmad

Damn I think I know the answer already so WHAT IS the purpose of this VGA to HDMI cable I have?
I got it some time ago with the intent of eventually going to a 1080p screen and now I am trying to use it but the television says no signal.
If the cable can not take the VGA output from my computer and put it into the HDMI on its other end what is the purpose of these cables?

I hate to bump such an old topic, but that's not why they made HDMI. HDMI was made for DRM control
VGA is easily able to do what HDMI does. Heck, the monitor and VGA cable I'm using on my computer is capable of 2048x1536. That's well beyond 1080p's resolution
I have been reading this thread and I am wondering the same thing. I have tried desperately to figure out on my own how to take our 27" Phillips LCD HDTV (1080p) and use it as a computer monitor (mainly to watch movies that we have on our PC). I am thoroughly confused now after doing the research because I see so many names of cables and converters. VGA, HDMI, DVI, then there's VGA to HDMI, HDMI to VGA, etc, ect... Can you provide me with a simple answer of what I will need to use my TV as a monitor?

Sometime, I mean you cann't change some big equipment (such as expensive security equipment) to be with HDMI port right now, then you need a converter.

I have connected my laptop to my HDTV using an analog RGB cable. My HDTV has an Analog RGB PC input, so I connect to my laptop. great picture but no sound. I can't seem to find how to fix this. I need some advice. BTW, the laptop I have is old. It's a Toshiba.

May I be of assistance redcape?
It sounds like you have done a great job already. I'll assume your old Toshiba laptop does not have HDMI or DVI out... right?
Sound is not carried over any video cables usually. Sometimes an internal SPDIF or similar connection can be made from a desktop mobo or audio-card to the video card so sound will be passed through the video cable. If your laptop does not already do this I would say it's a no go.
What sort of audio outputs does your lappy have? Do you only have headphones out or is there other audio outputs? See if you can use some separate audio connection cable(s) to the HDTV (if that's possible) i.e. see if you can input sound from your lappy independently from the video signal. Barring that, your best bet is to connect to a receiver/amp ~ so you need a phono to RCA cable. Or just connect to some ordinary desktop computer speakers for louder sound. Usually you can change the output from "headphones" to something like "speaker out" with the audio drivers, but that is not essential.
Only recently have ATi bought out video cards ~ the Radeon HD 5xxx PCI series ~ with audio processors onboard so true HD 7.1 channel (or lower) can be passed over a compatible AV cable (like HDMI) to a device. This has not been possible before without a special PCI audio card.
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
TO OTHERS posting on this thread about the best connection to a HDTV:
For heaven's sake... if your rig has no HDMI output but has a DVI output use that with a DVI to HDMI adapter plug or cable.
It's cheap.
You can go via DVI to the VGA input to the telly in the same way, if you have to, but you will not get the best signal quality/resolution if you do. Most, if any, HDTVs do not offer full 1080p via VGA. It's a route to take if you have no alternative.
See above for the audio considerations.
Cheers.

Probably it won't work. Vga to dvi is possible, because there are two kinds of dvi signal (DVI-I, which has both analog and digital output, and DVI-A which has only the analog output.). So if you hook in the vga->dvi cable, the signal will analog on the dvi-end of the cable. Since hdmi is digital, it doesn't support analog signals.
But there are signal converters that can convert digital to analog rgb, but they cost like 300$ at least. So you'll need a hdmi to dvi -cable and a signal converter similar to this:
http://www.ramelectronics.net/html/DVI_ADC-converter.html
Not necessary. You don't need a DVI converter, just use the VGA to HDMI converter listed on the website below. The website includes a video walk through for how to transfer analog to digital and how to transfer audio.

Does anyone know how to connect my laptop (vga output only) to my tv (dvi input only) using an vga - dvi cable? When i plug it in nothing happens on the laptop besides it asking me if I want to use different monitors etc. Then after nothing happens despite if I want different monitors? Any advice?

Actually HDMI was made for digital A/V transfer (both in the same cable). DRM comes along with that. Yes, of course vga can deal with same resolutions as HDMI, but the signal is still analog. So it's for better quality (and DRM).
Analog can be infinitely better than a Digital signal, since a digital signal is based on it's own limited digital resolution, and always will hit it's own Digital brickwall because of technology.
Analog in theory is infinite in resolution if you can translate a pure Analog signal correctly. It does take expensive electronic gear to do it right. Why do you think they still use quality Analog equipment for Film, TV and Audio Sound, instead of using digital ? Because of the much higher resolution an Analog signal can achieve. The problem with Analog is that it can have multiple generation loss and noise can build up, and it can have harmonic distortion.
With digital on the other hand, you can get rid of most of the noise, also most of the harmonic distortion. You just don't have the super high resolution original Analog Wave Form represented exactly by the Digital translation process.
Also making multiple Digital copies is much easier than Analog, and can be much less signal loss due to it's own digital copying accuracy. However the Digital signal will not represent the original Analog signal 100%. Digital resolution obviously depends on how good the Analog to Digital conversion is, and of course the back to Analog processing. The higher the Digital Sampling rate or bit rate, the better the results, the better the picture and sound is.
Because Analog does not rely on sampling rates, if the source is direct and pure, then the Analog signal always will be of higher resolution than the Digital signal. And how good that Analog signal is converted electronically makes a huge difference in the end results. So for now, Digital and Analog can be almost as good and compliment each other on mid to high end consumer gear. Digital seems to be getting better and better all the time, who knows when it will be as good as quality Analog Gear ?
Analog is real life, the way your ears hear in reality, or the way your eyes see in real life, but digital is a fake representation of that reality, doing its best to reproduce accurately but falling short due to it hitting it's own Digital brick wall, it's Digital resolution limit of ones and zeros. Until we have no limits in the electronics and the complexity of the A/D to D/A converters, Digital will be limited in resolution.
Digital as well as Analog will always have its limitations to reproduce absolutely accurately due to its lack of electronic accuracy, and it's many errors in the electronic conversion process.
So an Analog wave is a pure infinite resolution wave form, with no Digital stair steps, with no Digital quantization noise shaping and frequency filtering errors. Also Analog can have a much lower and higher frequency response than Digital can, another words a much higher bandwidth resolution. The only true limitations in accuracy are the electronics, picture screen, and audio speakers converting the original Analog signal.
Although Digital has come a long long way now, it is still not as good as the real thing called the original Analog signal. I do not think any device will ever be perfect in reproducing the origiinal signal.

The problem is that although for my home pc i bought a dvi to hdmi cable and i can hook it up to my new HDTV, my laptop doesn't have
a dvi output so i am stuck with the vga output.
Can i convert from vga to HDMI directly? will it work if i buy VGA to DVI and then DVI to HDMI? also it seems like the dna drivers have an option for forcing 720p output for the card anybody tested that?

i just bought a vga to hdmi cable, my tv only has one hdmi port and i need that for my xbox, it a pain to keep switching between cables. ive tried vga in the laptop and hdmi in the tv, and hdmi in the laptop and vga in the tv, neither way works, i want to know if this conversion is even possible or if its just the cable i have.
Ive seen these cables on amazon so i assumed their legit and bought one off ebay.

Hey, u seem to know quite a bit about the connectors from computer to tv....My question is simply, that my computer is older and doesnt have the hdmi output but has the VGA or hddb15 prong....could I take the VGA hddb16 prong and then use the hdmi end to connect to the TV?? I am young and just starting a living with a gf of mine and cable isnt a priority but the computer to tv seems to be the best alternative, let me know perhaps with an email back thank you so much for your help

I know this thread is crazy old, but i happened upon it from google. The most recent posts still seem to have some confusion about VGA to HDMI and things like that, so Im posting this to try and help.
As some people have already stated, VGA is analog and HDMI is digital. This means that you cannot use a simple VGA to HDMI cable to connect the two. For some reason there are some companies producing such a cable, but it really doesnt work.
This doesnt mean, however, that you cannot connect from VGA to HDMI. All it means is that you need a VGA to HDMI signal converter. This converter will take the analog VGA signal and convert it to the digital HDMI format. Most of these converters also include a scalar that will adjust the resolution to be in one of the resolutions supported by your HDMI display. Most also include an audio signal input in order to put your audio on the HDMI output as well since HDMI carries both video and audio (unlike VGA).
Because its not just a cable it is a little more expensive, but it can still be extremely helpful in certain situations. Quite a few companies sell these things these days like Atlona and Gefen, but a really nice one Ive found that sells them for a much more reasonable price is Sewell Direct. They have an article that talks a little more about this here:
Vga to hdmi converter
They also show off what they have to get the job done. If any of you still have questions about this sort of thing, I bet these guys could answer them quick enough. I hope this clears this up a bit for anyone else who stumbles across this thread via google like i did.

Converting VGA to HDMI is a waste of time and money. You will see no improvement with the conversion. In fact you may see a degradation in video quality.
Either stick with VGA or upgrade to HDMI.
