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

VGA是三个最古老的标准,在1987年已经出台。 VGA视频只和不发声,处理不包含安全或数字版权管理,并且是一个模拟信号,这意味着该电缆的质量,销的质量,并从PC到显示器的距离都可以在有效果视频质量。如果你的连接器有小翼形螺钉旁边的电缆,看起来像左边的图形,它的VGA。

HDMI接口,它最早出现于2003年,经常被发现在现代的电视,但也是大多数较新的PC显示器,并迅速成为大多数笔记本电脑所需的硬件。 HDMI是一种数字标准,这意味着该连接可以是在(1)或关(0)。电缆的质量,从机器到监视器和金属连接器类型的距离都几乎无关(所以不支付一大堆你的HDMI线!)HDMI可以同时处理的安全性,这意味着某些类型的信号,诸如付费电视,可从沿HDMI电缆行进受阻。 HDMI声音处理以及视频,所以用一个耳机插孔和HDMI连接线可以输出的声音从你的笔记本电脑的显示器。 HDMI貌似中间的图形。

DVI发明于1999年,是类似于VGA和HDMI接口。它可以为数字,模拟,或两者进行配置,它可以处理数字版权管理,并且可以通过转换线或加密狗(小转炉设备)转换为两个HDMI和VGA。更可能的,你的显卡有HDMI和DVI连接器,或一个或另一个,而且往往会附带要求的加密狗。它不支持声音​​HDMI一样呢,看起来像右图以上。

现在你知道这些类型的电缆之间的差异,而各优缺点。认为自己学历上的视频连接器!

    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?

  • reviversoft

    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.
