Can a VGA cable HD video signal to 720p or 1080i lead from a PC to an HDTV? CompoNet or HD cable / HDMI is needed to maintain a high definition signal?

VGA is analog RGB component video. It can carry video signals to High Definition (480i, 480p, 576i, 576p, 720p, 1080i and 1080p). It is actually very similar to the video component, which even with a high-definition signal can. The difference is the use of YPbPr component video instead of RGB.

DVI and HDMI are digital video signals, including the implementation of high-definition video signals can. Since they are digital, they can take more distance without signal management problems. This makes the DVI and HDMI is better because it signals a little better look, but for ordinary mortals to virtually no difference between high-definition analog and digital HD.

The key to connect a computer to an HDTV is what connections are on the PC and watch TV, and what resolution your video card is capable of providing, and what your HDTV can show resolutions. If you have a VGA output on the graphics card and the VGA input on your TV have, while the graphics card can generate an HD signal (some only a few resolutions for HD output), you can easily to your PC orTV, with DVI on your computer. You can also use a DVI to VGA adapter for pretty cheap if you DVI on your computer, but also for HDTV VGA (VGA, though less frequently on television, and probably DVI or HDMI). HDMI is the same as DVI except that it also cause that an audio signal into one cable. That makes the question of a simple (cheap) DVI to HDMI and vice versa.

For example, my PowerMac G5 has DVI output, I connected directly to my HD projector. Leave the full HD resolution can I upgrade my current graphics card is 1080i, which can also display the best of my projector. Before I could afford a long enough DVI cable for video output of the projector, I used a DVI to VGA adapter to connect to my VGA projector. I was still able to get 1080i on my projector, but is digital a little more clearly, especially at a distance of 30 meters from my computer to the projector. Like I said, many people who have had to watch films on my projector with me, I'm the only one that all dIFFERENCE When I switched from analog to digital, but I spend a lot of time in the processing of video and studio) quality (his hobby.

VGA, DVI, Component, HDMI, and can lead to HD resolutions. I think HDMI is the only one, albeit 1080p24 support. But beyond that you can use any other to carry a video signal in high definition. HDMI is the only portion that can carry video and audio. All other and we must do something more, audio (stereo mini jack to RCA or headphone / line out, optical audio, or if your computer is supported).
