之间有什么VGA,HDMI和DVI的区别?What’s the Difference Between VGA, HDMI and DVI?

几乎可以肯定,显示器和PC之间的连接是三种类型的电缆之一:VGA,HDMI和DVI。那有什么区别?

VGA是三者中最古老的标准,于1987年推出.VGA只处理视频而不是声音,不包含安全或数字版权管理,是一种模拟信号,意味着电缆的质量,引脚的质量,从PC到显示器的距离都会对视频质量产生影响。如果你的连接器在电缆旁边有一个小拇指螺丝,看起来像左边的图形,那就是VGA。

最初出现在2003年的HDMI经常出现在现代电视机上,但也出现在大多数新型PC显示器上,并且在大多数笔记本电脑上迅速成为必需的硬件。 HDMI是数字标准,意味着连接在(1)或关闭(0)。电缆的质量,从机器到显示器的距离以及连接器中的金属类型都几乎无关紧要(所以不要为HDMI线缆支付太多费用!)HDMI也可以处理安全性,这意味着某些可以阻止付费电视等信号类型沿HDMI线传输。 HDMI可以处理声音和视频,因此带有耳机插孔和HDMI线的显示器可以从笔记本电脑输出声音。 HDMI看起来像中间的图形。

DVI发明于1999年,类似于VGA和HDMI。它可以配置为数字,模拟或两者;它可以处理数字版权管理;它可以通过转换器电缆或加密狗(小型转换器设备)转换为HDMI和VGA。您的视频卡很可能具有HDMI和DVI连接器,或者其中一个,并且通常随附所需的加密狗。它不像HDMI那样支持声音,看起来像上面的右图。

现在你知道了这些类型的电缆之间的差异,以及每种电缆的优缺点。考虑自己受过视频连接器的教育!

    I am very glad thet can to read for HDMI.thanks

    HDMI cable 10 meters long,will bi good for transoport(audi and video) from my PS to my TV?

  • Hi Simeon,
    Yes … the nice thing about HDMI is that it can be almost any length, and the signal won’t degrade, since it’s a digital cable. You can also purchase inexpensive HDMI cables and get exactly the same quality signal as you would with an overpriced cable.

    Good luck!

    where are these ports present are they on laptops or the television

    Hi,

    I have an acer s3-391 laptop with an HDMI Port (output). I need to connect it to a projector which has a VGA (input).

    I understand that the Laptop (HDMI port) would send a digital signal output whereas the projector (VGA Port) is compatible to receive analog signal.

    Is there some connector or adapter that can be used to switch the signal from digital to analog?

    Hi Abhishek,
    Yes, there are many HDMI out to VGA in convertors out there. Be aware that you may run into digital rights management issues if the HDMI signal carries them. Good luck!

    Foam,
    Ports can be found on any device. Which devices are you asking about specifically?

  • Davide De Vellis

    Hi Gerard,

    You can purchase an adpater to convert your VGA output into HDMI to be able to then plug into your TV. The other problem you will likely face is that since your PC is older there will be compatibility issues. VGA is an analog signal where HDMI is digital. You’re graphics card would need to be able to send Digital signal which is unlikely in an older computer. You can buy a converter but then you really need to consider if it’s worth the time and effort.

    Thanks Steve for such a good and short explanation! It’s quite clear.
    I have a tv with both vga and hdmi connections, and only vga on my pc. Exit vga! I can throw it away! (for now, what the need for?)
    Thanks again,

    I tried and failed to persuade my old monitor to accept a VGA to DVI converter, tried three different ones but no go. So cannot use the graphics card in the newer computer, have to use the inbuilt graphics connection at the mo which isn’t much good. New monitor definitely required.

    Thank you for info.

    There is a fourth standard, DisplayPort. It would be nice if you added this to your article.

  • HDMI is the most common connector. But if you want to connect a computer to your TV (or you’ve got a new computer monitor), the options tend to be HDMI, DisplayPort, DVI, and sometimes old-school VGA.
