Default S-Video vs. VGA for Laptop Connection

I don't have HDMI or DVI outputs on my laptop. My options are S-Video or VGA. Any thoughts on which would be best, or if there's any difference? I can't seem to find one, other than the S-Video cable being a lot easier to run.

Also, my graphics card does not support standard HD resolutions. I have 1024 x 768, 1280 x 768, 1024 x 1280, 1400 x 1050, 1600 x 1200, 1920 x 1200 and the reverse of each. Any idea which ones will be least problematic?

Thanks in advance!

use the VGA set your computer to 1024x768 and 60~ refresh - it should work that way - try the other resolutions later - always use 60~ refresh on your computer unless your HDTV manual says it will accept higher or lower refresh rates on the VGA - S-Video will give you a maximum resolution of less than 400x300 and poor color and blurry text.- as well as over-scan - don't use it -

Yes use the VGA, VGA is similar to component video and a much better connection than S-Video. VGA is high definition capable and a high quality analog connection.

Thanks a lot! I'll run VGA instead. 60hz it is.

Damn, turns out my TV doesn't have VGA input. Any other ideas? I can't easily add a video card to my laptop.

If your TV has Component:

Use a cable with VGA on one end and component on the other. This will work fine and no adapters are required.

Excuse me? VGA has three component analog signals (R, G, and B) with NO sync at all on them, and separate 5 volt horizontal and vertical sync signals on two separate leads.

If you connect up just the three RGB component leads from a VGA cable to your set, it has no sync to go on. Won't work, sorry.

Not to mention that a consumer display with component analog inputs is looking for Y, Pb, and Pr signals which are not the same signals as pure R, G, and B in a VGA signal. Even if it did work as you suggest, the colors would be all wrong.

Sometimes a display with a VGA input can accept a component analog Y, Pb, Pr signal because it's set up internally to decode those signals into RGB, but not vice-versa. He's got a laptop with a VGA output and he's looking for a way to connect it to his display. At this point aside from spending big bucks for an external converter of some kind, the only alternative he has is to use s-video and live with the limited picture quality.

What scoosdad said is exactly correct and what Rich Guy is saying applies to certain video cards that will support both VGA and component video. If your laptop has one of those video outputs (doubtful) then the adapter cable may work, otherwise you will need a VGA to component transcoder.

Next, if your TV does not have a VGA input then it may not support any computer resolutions other than 640x480. At that point the s-video would be similar.

Opps, I guess I was thinking those cables worked without any hassles. I never had any need for them myself so I had never tried to use one. I remember reading somewhere that VGA and component were very similar video connections as far as quality and such so I thought the cables sold with VGA on one end and component on the other made sense.
I use VGA from my computer to VGA on my plasma display and this works very well. Sorry for the confusion.

So far he hasn't mentioned the model of the HDTV - Some (Sharp e.g.) use the DVI-I connection for the VGA input.
If he reads the manual a little closer - he may find his DVI-I connector is designed for that (dual) use. The cord for that purpose is readily available on line for less than $30 for a ten foot - I bought my 10' VGA > DVI-I for $13 locally

The television is in my sig. It's a sharp Aquos 52" 1080p. According to the manufacturer it has no dedicated PC input. S-Video, Component, HDMI only.

Sorry my chosen forum display format doesn't show the sigs or avatars - My Sharp LC52D92U 1080p does have VGA input via the DVI-I as mentioned in my last post - it accepts most PC formats up to 1600x1200 on that input [#7] plus ATSC HD formats (per the manual)

Just has an idea. If I send my S-Video into my Tuner, won't it handle the conversion to Component Out? I know it won't convert to HDMI, but as far as I know it will convert up most formats to Component. Please advise. Thanks!

I think the LC-60C52U is lacking that input. I'd love to be corrected if that's not the case. I would normally just look and see, but it's on a Fed-Ex truck until tomorrow. Just trying to figure out which cables to run.
