Alright guys, I have a Sager NP 8662. It has a standard audio output (headphone), and has HDMI and DVI outputs. I want to have it go to a composite feed (red yellow white), so it will be able to work on like any tv. So pretty much, what is the best way for a hdmi or dvi to yellow composite rca. Can any1 help please?

First, if you are wanting to try to hook your PC to a CRT(Analog) type TV I do not think you will be able to do it. This is because you will need to be able to lower your PC resolution to less than 800x600 due to the fact that analog TVs can't go beyond 480i (600x480). I do not believe that the GPU in your machine is able to go down that low.

If your just going for LCD TVs and the like then you don't need to go composite which is horrible anyway.

If your curious you might look at Monoprice.com. You should be able to find a cable changer or converter box. The problem is the boxes don't work all that well and even if you do find one you still have to be able to lower your PC resolution to 600x480.

Not my area of knowledge but will take a stab. You are basically asking is there an adapter for HDMI/DVI to RCA? Answer is no. Both HDMI/DVI are outputting digital, RCA is analog. What you need is a converter that makes digital to analog. They do sell but more than an adapter. I looked at your system specs, I wanted to see a S-video I did not.

Like said not my area I could be wrong but do not think so at this time.

So a converter is your best bet good luck. It is doable.

Conveter, adapter, w/e. Is there a converter u know of?

Like would a dvi to vga, then vga to composite like http://www.google.com/products/catalog?q=vga+to+composite&oe=utf-8&hl=en&cid=15223743978350771745&sa=title#p work?

I tried posting last night, but the system would not let me for some reason.:(

Here's the thing: If you are trying to hook up to a CRT (analog) TV you first have to be able to lower the resolution on your PC to 600X480 (480i) or thereabouts. I doubt you can get the res that low on the GTM260. I can't even get lower than 800X600 on my little Force with the 8600GT.
(If your PC's native res is 1650x1080 you'll get down to 800x600 or if higher you'll get down to 1280x1020 or whatever that number is).

Even with a converter box I doubt it will work. For one thing those converter boxes do not work most times and they run around $70, sometimes less depending on where you get one. Also I think you still need to lower the res on the PC in the first place.
There are no adaptors for converting DVI/HDMI to Composite. I don't think there are adaptors for converting VGA to Composite either, I could be wrong. There are adaptors for converting S-video to Composite though.

Just a note: Composite and sometimes S-video look horrible and can be unviewable. Not always, but quite often the case.

You might try looking here: http://www.monoprice.com/home/index.asp if your really curious.

This looks like it would work but $250, link (http://www.hdtvsupply.com/dvitocomposite.html).

Interesting....I didn't realize the 8662 didn't have any type of analogue output.

It does come in handy sometimes in hotel rooms where Digital input isn't available and I want to watch movies from my laptop on the room's TV. S-video is the lowest I would go since composite is just too poor a quality level to be considered usable on any sort of modern TV. Most televisions also have a VGA input which also works very well....better than S-video since higher resolutions are supported and it's also analog.

If you don't have built in analog out it's probably not worth trying to convert a digitial signal outside your PC since it seems expensive. Better to bypass your video card altogether and use an external video device such as these:

and combine it with an adapter such as these:

Here's another option:

It requires a VGA in but DVI to VGA adpaters are easy to come by and you may already have one. Not sure how well any of these solutions would work but at least they're affordable.

I mean with the converter of dvi to vga, why cant i just use a vga to composite after that?

You can get a VGA to composite after you convert the signal from digital to analog with the DVI-VGA converter. However as others have mentioned before, the video card on that unit probably wont output in 640 x 480 which is what is required on a CRT analog type television. There are probably really cheap adaptors you could get DVI ->>VGA-->composite/s-video. However I think you are still limited by the output.
