本文将教您 如何(how to connect your PC or computer to a TV or HDTV )使用有线和无线连接将您的 PC 或计算机连接到电视或高清电视。这些天你有很多选择，所以这真的取决于你的硬件和预算(hardware and budget)。目前最常用的方法仍然是将电缆从笔记本电脑连接到电视，所以我将首先介绍这些方法。
但是，如果您最近购买了MacBook Pro之类的笔记本电脑，那么有一种方法可以使用Apple AirPlay将屏幕上的任何内容无线传输到电视上。不幸的是， Windows(Windows)计算机还没有类似的东西，即使是在Windows 8发布的情况下。由于无线流媒体功能，这是一个比 PC 购买Mac更有利的领域。(Mac)
通过电缆将笔记本电脑连接到电视
S-视频
五年前，这曾经是将笔记本电脑连接到电视的最常用方法，因为S-Video电缆很便宜，而且当时几乎每台笔记本电脑和电视(laptop and TV)都有一个S-Video端口。如今，很难找到带有 s-video 端口的笔记本电脑，尽管许多现代电视(TVs)仍然包含该端口。请记住(Remember)，有两种类型的S-Video电缆：4 针和 7 针(4-pin and 7-pin)。大多数笔记本电脑和 PC 都配备了 7 针端口，因此如果您的电视只有 4 针S-Video 端口(S-Video port)，那么这种方法将不起作用，或者您必须获得适配器。
S-Video 画质(picture quality)中等，不支持高清视频(high-definition video)。此外，S-Video端口不支持音频，因此您必须为此购买单独的电缆。DVI 和 HDMI(DVI and HDMI)最适合高清信号。
VGA
VGA和S-Video一样，是当时所有笔记本电脑和(S-Video)TVs/computer屏幕上的另一个常见端口。同样(Again)，您仍然可以在HDTV 和显示器(HDTVs and monitors)上找到该端口，但在笔记本电脑上找不到。大多数台式机仍然支持VGA ，并且背面有VGA端口。(VGA)在画质(picture quality)方面，VGA优于S-Video。此外，与S-Video 电缆(S-Video cable)一样，VGA电缆非常便宜。VGA线不支持音频，就像S-Video 线(S-Video cable)一样。
DVI
DVI 代表数字视觉接口(Digital Visual Interface)，“数字”是那里的关键词(key word)。数字信号将提供比S-Video 或 VGA(S-Video or VGA)更高质量的图像(quality picture)。当然，您的计算机需要有DVI 连接(DVI connection)，而您的电视需要是HDTV。DVI电缆过去很贵，但现在您可以在网上以 5 到 10 美元的价格买到它们。此外，DVI电缆也不支持音频，因此您仍然需要单独的电缆。
DVI电缆也有点复杂，因为您有DVI-I（单链路(Single Link)）、DVI-I（双链路(Dual Link)）、DVI-D（单链路(Single Link)）、DVI-D（双链路(Dual Link)）和DVI-A。DVI之所以流行，是因为它也支持模拟连接，即VGA。您可以购买DVI转VGA 适配器，在(VGA adapter)DVI 输出和 VGA 输入(DVI output and VGA input)等之间进行转换。
HDMI
HDMI（高清多媒体接口）将为您提供(High-Definition Multimedia Interface)高清电视(HDTV)上最优质的画面(quality picture)。尽管HDMI非常流行，但许多笔记本电脑仍然没有内置HDMI端口。(HDMI)幸运(Luckily)的是，HDMI与DVI兼容，因此您可以使用HDMI转DVI 电缆(DVI cable)将其连接到您的高清电视(HDTV)。不幸的是， 这些天HDMI电缆非常昂贵。您可以购买便宜的，但您可能无法获得与更昂贵的电缆相同的质量图像。(quality picture)
还有许多版本和类型（A 到 E）的 HDMI 电缆(many versions and types (A thru E) of HDMI cables)支持不同的功能，例如音频、HDMI上的 3D 、以太网(Ethernet)和 4K分辨率支持(resolution support)。HDMI线最好的部分是您可以通过该线获得高清视频和音频，这使得将(video and audio)笔记本电脑或 PC(laptop or PC)连接到HDTV时非常方便。
显示端口
DisplayPort 和 Mini-DisplayPort(DisplayPort and Mini-DisplayPort)与 HDMI非常相似，DisplayPort(HDMI and DisplayPort)旨在补充HDMI，而不是取代它。DisplayPort的基本优势在于它可以通过一根电缆支持多达 4 个视频和音频流。这意味着您最多可以连接 4 台 1920×1200 的显示器或 2 台 2560×1600 像素的显示器。
HDMI仍然更受欢迎，但您会在Apple计算机、Microsoft Surface平板电脑甚至某些Windows PC上找到(PCs)DisplayPort端口。DisplayPort还向后兼容VGA 和 DVI(VGA and DVI)，这很好。
将笔记本电脑无线连接到电视
除了使用电缆将笔记本电脑连接到电视之外，您还可以使用新的无线技术将笔记本电脑的显示屏无线投射到电视上。我将提到目前存在的几种不同技术，并解释需要哪些硬件。不幸的是，将笔记本电脑和台式机显示器无线传输(reason wireless streaming)到电视(TVs)并没有普及的主要原因是所需硬件的额外成本。
苹果电视
英特尔无线显示器
Mac(Macs)上支持的AirPlay 功能是(AirPlay feature)Windows计算机长期以来缺少的一项功能。幸运的是，情况发生了变化，英特尔(Intel)推出了一项名为英特尔无线显示(Intel Wireless Display)( WiDi ) 的技术，可让您将笔记本电脑的屏幕以无线方式传输到高清(HDTV)电视。
当然，与AirPlay 技术一样， (AirPlay technology)WiDi的主要缺点是它相对较新，因此只有在您拥有支持(WiDi)WiDi的 PC 时才能使用它。如果您打算很快购买新 PC，则应查看该功能是否受支持，因为它可以使您的笔记本电脑或 PC 屏幕(laptop or PC screen)相对容易地流式传输到HDTV 。
目前只有几台高清电视(HDTVs)支持WiDi ，但您可以为任何(WiDi)高清电视(HDTV)购买一个适配器，让您从支持WiDi的设备将内容流式传输到该电视。
无线套件
如果您的计算机中没有任何这些技术或想要一些非专有的东西，那么您可以购买无线计算机到HDTV套件。其中有很多，我将链接到一些我听说过的关于我自己的流行的。
Imation Link Wireless HD Audio/Video Extender – 支持高达 720p 的视频，也可以传输音频。需要适用于Mac 和 PC的(Mac and PC)DisplayLink 软件(DisplayLink software)。
Veebeam HD – 该套件支持 1080p 无线高清视频(HD video)和数字音频。
Netgear Push2TV – 这适用于我上面提到的新英特尔无线显示技术(Intel Wireless Display technology)，需要支持WiDi的 PC 。到目前为止，它根本不支持Mac OS。
因此，您可以选择通过有线或无线方式将笔记本电脑或 PC(laptop or PC)连接到电视。最快和最可靠的方式仍然是通过电缆，但如果您的计算机支持最新的AirPlay 或 WiDi 技术(AirPlay or WiDi technology)，您就可以开始了。无线套件使用低于标准的技术，不会像提到的其他技术那样给您带来好的结果。享受！
How to Connect Your Laptop/PC/Computer to Your TV
This article will tеach you how to connect your PC or computer to a TV or HDTV using wired and wireless connections. You have many options these days, so it really depends on your hardware and budget. The most common method currently is still by connecting a cable from your laptop to your TV, so I’ll go over those first.
However, if you have bought a laptop like the MacBook Pro recently, then there is a way to wirelessly stream whatever is on your screen to your TV using Apple AirPlay. Unfortunately, there is nothing like that for Windows computers just yet, even with the release of Windows 8. This is one area where it’s advantageous to buy a Mac over a PC because of the wirelessly streaming feature.
Connect Laptop to TV via Cable
S-Video
Five years ago, this used to be the most common method for connecting a laptop to a TV because S-Video cables are cheap and just about every laptop and TV back then had a S-Video port. Nowadays, it’s rare to find a laptop with an s-video port, though lots of moderns TVs still include the port. Remember, there are two types of S-Video cables: 4-pin and 7-pin. Most laptops and PC’s are equipped with a 7-pin port, so if your TV only has a 4-pin S-Video port, then this method will not work or you’ll have to get an adapter.
S-Video picture quality is moderate and does not support high-definition video. Also, S-Video ports do not support audio, so you’ll have to buy a separate cable for that purpose. DVI and HDMI are best suited for HD signals.
VGA
VGA, like S-Video, was another common port found on all laptops and TVs/computer screens back in the day. Again, you’ll still find the port on HDTVs and monitors, but not on laptops. Most desktops still support VGA and have VGA ports on the back. In terms of picture quality, VGA is bette than S-Video. Also, as with the S-Video cable, VGA cables are very cheap. VGA cables do not support audio, just like S-Video cables.
DVI
DVI stands for Digital Visual Interface with “digital” being the key word there. The digital signal will give a higher quality picture than either S-Video or VGA. Of course, your computer will need to have a DVI connection and your TV will need to be an HDTV. DVI cables used to be expensive, but now you can get them for $5 to $10 online. Also, DVI cables to do not support audio either, so you still need a separate cable for that.
DVI cables are also a bit complicated as you have DVI-I (Single Link), DVI-I (Dual Link), DVI-D (Single Link), DVI-D (Dual Link) and DVI-A. The reason why DVI became popular is because it supports analog connections also, namely VGA. You can buy a DVI to VGA adapter to convert between a DVI output and VGA input, etc.
HDMI
HDMI (High-Definition Multimedia Interface) will give you the best quality picture on a HDTV. Even though HDMI is very popular, a lot of laptops still do not come with HDMI ports built-in. Luckily, HDMI is compatible with DVI, so you can get a HDMI to DVI cable to connect it to your HDTV. Unfortunately, HDMI cables are pretty expensive these days. You can buy cheap ones, but you may not get the same quality picture as a more expensive cable.
There are also many versions and types (A thru E) of HDMI cables that support different features like audio, 3D over HDMI, Ethernet, and 4K resolution support. The best part about HDMI cables is that you get high-definition video and audio passed through the cable, which makes it very convenient when connection a laptop or PC to your HDTV.
DisplayPort
DisplayPort and Mini-DisplayPort are very similar to HDMI and DisplayPort is meant to complement HDMI, not replace it. The basic advantage to DisplayPort is that it can support up to 4 video and audio streams across one cable. That mean you could connect up to 4 monitors at 1920×1200 or 2 monitors at 2560×1600 pixels.
HDMI is still more popular, but you’ll find DisplayPort ports on Apple computers, the Microsoft Surface tablets, and even some Windows PCs. DisplayPort is also backwards compatible with VGA and DVI, which is nice.
Connect Laptop to TV Wirelessly
In addition to connecting your laptop to your TV using a cable, you can also wirelessly project your laptop display on your TV using new wireless technologies. I’ll mention a couple of the different technologies that currently exist and explain what hardware is needed. Unfortunately, the main reason wireless streaming of laptop and desktop displays to TVs has not become ubiquitous is because of the extra cost of the hardware needed.
Apple TV
Intel Wireless Display
The AirPlay feature that is supported on Macs is one feature that has been missing on Windows computers for a long time. Luckily, things have changed and Intel has come out with a technology called Intel Wireless Display (WiDi), which lets you stream your laptop screen to an HDTV wirelessly.
Of course, the main downside with WiDi as with AirPlay technology is that it’s relatively new and therefore you can only use it if you have a PC that supports WiDi. If you’re planning on buying a new PC soon, you should look into whether the feature is supported or not as it can make streaming your laptop or PC screen to your HDTV relatively easy.
There are only a couple of HDTVs that support WiDi right now, but you can buy an adapter for any HDTV that will let you stream content to that TV from a WiDi enabled device.
Wireless Kits
If you don’t have any of those technologies built into your computer or want something that’s not proprietary, then you can buy wireless computer to HDTV kits. There are quite a few of these out there and I’ll link to some of the popular ones I’ve heard about myself.
Imation Link Wireless HD Audio/Video Extender – Supports up to 720p for video and can transmit audio also. Requires DisplayLink software, which is available for Mac and PC.
Veebeam HD – This kit supports 1080p wireless HD video and digital audio.
Netgear Push2TV – This works with the new Intel Wireless Display technology I mentioned above and needs a PC that supports WiDi. It doesn’t support the Mac OS at all as of right now.
So those are your options for connecting your laptop or PC to your TV via wired connection or wirelessly. The fastest and most reliable way is still via cable, but you if your computer supports the latest AirPlay or WiDi technology, you’ll be good to go. The wireless kits use sub-par technology and won’t give you as good results as the other technologies mentioned. Enjoy!
