Why not a cable that connects video or VGA signals?

Popular video connection cables, including Composite video and VGA, only undertake analog video signal transmission. This capability is very suitable for CRT monitors but is not compatible with new LCD models today. Many LCD TV devices and computer monitors can still use this cable standard, but if you want a better display quality, choose DVI or HDMI standard.

So what is the difference between these digital cables?

DVI port

It is very popular and recognizable, which is quite similar in appearance to the VGA port with 24-pin signal, which supports good analog and digital video signals. The DVI standard can display 1920 × 1200 HD video resolution, or with dual DVI standard, this resolution can be up to 2560 × 1600 pixels. And some DVI cables have fewer signal pins than those for low-resolution devices, so consider using appropriate options and uses. If the connection port you use has enough pins, they will fully support the resolution to the maximum without any problems. But the weakness of DVI is that it does not support HDCP encryption standard in the default mode, so there are cases where the video card of a user with only DVI drive will not be able to display the full HD Blu-ray. and some other HD standards.

On the other hand, you can still connect DVI to HDMI port on the LCD monitor with a small signal converter, which is the DVI to HDMI converter. But since DVI no longer supports audio signals, users need to add another separate cable when connecting to the HDMI port. This gives more flexibility to the DVI standard with compatibility with both old and new connection standards. In addition, users can still connect to the old monitor with only VGA via DVI port and the DVI to VGA converter - similar to the above.

DisplayPort

As mentioned above, DisplayPort is a fairly new video signal transmission and connection standard, and is equipped on today's modern digital devices, mostly laptops, for example. products of Macs, Dell, HP and Lenovo. It can be considered a successor to DVI and VGA standards on computers, but currently cannot compare and replace DVI and HDMI. Its appearance is quite similar to HDMI, capable of transferring HD video and audio signals, the maximum resolution can be achieved at 1920 × 1080 with 8 audio channels.

The plus side we need to mention here is the ability to support HDCP encryption standards, so it can be used with devices that contain HD protected content, such as Blu-ray discs . Next You can also connect to an HDMI or DVI port with a conversion device - users will have to purchase the converter if they want to connect laptops to large-screen displays.

Standard cables can reach 49 'in length (about 15 meters) without losing signals, so consider when choosing to buy a cable, connecting devices and enjoy the technology.

If you currently have a DVI or VGA cable, or both should not be changed or upgraded, simply because you really don't have to.
