I was just reading on Digg how much the stores' profitmargin on cabels like HDMI.

That reminded me that we have HD TV and I have an HDMI cabel, but since the cabelbox doesn't have an actual HDMI connection, we use the usual set up. Back when we set it up Comcast BSed us, and I never bothered to ask for a new cabelbox. We are OK with the quality of the picture.

But if using the HDMI cabel actually makes a huge difference in picture quality than I would get a newer box. So is there a big difference???

An HDMI cable allows for a less degraded signal to reach your tV from whatever the output device is. They are much more expensive then they should be, and I dont think that the difference is worth the cost in most cases, but if you gotta have the best picture then you have to have one.

Thanks for the answer, I found one online, the summary:

"So, which is better, HDMI or component? The answer--unsatisfying, perhaps, but true--is that it depends. It depends upon your source and display devices, and there's no good way, in principle, to say in advance whether the digital or the analog connection will render a better picture. You may even find, say, that your DVD player looks better through its HDMI output, while your satellite or cable box looks better through its component output, on the same display. In this case, there's no real substitute for simply plugging it in and giving it a try both ways."

If you are going to buy an HDMI cable though, buy one online. It's way cheaper than at a retail store like Radioshack or BestBuy.

I think I mentioned that I already have a cabel, for more than a year, I just never used it.
Come to think of it, can I use it for the computer somehow? I mean do new computers or laptops have an HDMI connection??

Syzygys is right. I have a tv that is native 1080P and when I use HDMI the high def channels work really well, but the standard def look crappy. The standard def looks ok when I use component. It's really a matter of taste. If you have the time, and the inclination, just set up both inputs and switch between them to see which one you like best. Also it seems to me that HDMI works better for digital signals then anything else.

If you have a HD-DVD or BluRay dvd player, you should really use HDMI just to maintain the digital signal, but tat's just my opinion.

I have found RGB to be the best, even for HD i think it is superior to HDMI.

Are you using RGB for your signal or the yellow (video) connection. Because the yellow would be the worst by far.

OK, what is RGB?

It is 'component' video- YCbCr. It also supports 1080i\p and is much cheaper than HDMI cables. You wont see any difference between the two and RGB may even be better. RGB needs seperate audio cable. Do you have RGB connection on your TV and cable box?

OK, what is RGB?

It's the cable with three inputs. Red and white for audio, and yellow for video.

No thats composite cables, RGB is component and has three- RED, GREEN, and BLUE with seperate audio cable white and red.

yeah, the cabelbox has that. That's how it is hooked up right now...

Now I checked new laptops and some of them have the HDMI connection, so I can use the cabel for the next laptop, I guess...

Right, my mistake.
