For instance, S-video connections are now scarce, and some TVs may not allow the connection to the composite and component video inputs simultaneously. Here is a look at the rear connection panel of a typical HDTV and the connection cable examples. However, not all the connections shown in this example are present on all HDTVs. Connections such as S-video and component are becoming rare. Still, other connections not shown here , such as USB and Ethernet, are becoming more common.
Video projectors are becoming an affordable home theater option for average consumers. However, what are all those connections, and what do they do? Below is a photo of the typical connections you'll find on a video projector, with an explanation below. The specific layout of connections may vary from brand to brand and model to model. You might also see additional connections or duplicate connections not pictured here. Actively scan device characteristics for identification.

HDMI has limitations, though, and isn't always the perfect choice. If you've gotten a new 4K monitor, you're limited to 30fps. Not until HDMI 2. You'll also need new hardware and probably a new TV.
So in most cases HDMI is fine, but for really high resolutions and frame rates, one of these other options might be better. DisplayPort DisplayPort is a computer connection format. There is only one television with DisplayPort , and don't expect it to see much further adoption on the TV side.
It's capable of 3,x2,pixel resolution at 60fps, if you have at least DisplayPort 1. If you're looking to connect a computer to a monitor, there's no reason not to use DisplayPort. The cables are roughly the same price as HDMI. The maximum resolution potential depends on the equipment, though.
Some cables and hardware called single-link can only do 1,x1,, while others dual-link can do more. DVI generally doesn't do audio it varies. Since computer monitors don't usually have speakers, this isn't an issue. It's not too common anymore, and hardly ever found on TVs. A recent e-mail asked about it, so I'm including it. Don't use VGA, not if you can help it. While it is capable of fairly high resolutions and frame rates, it's an analog signal.
What about Thunderbolt? VGA can support resolutions up to x in 16 colors, although you can increase the colors to by lowering the resolution to x This is known as Mode 13h and is commonly used when booting your computer into Safe Mode. Mode 13h was often used for video games in the late s. The iconic blue adaptor comes with a screw on either side to secure the connection. The socket consists of 15 pins, arranged in three rows of five.
It has since been surpassed by digital connections like HDMI and DVI but is still popular thanks to the resurgence of retro gaming and its inclusion on cheaper monitors and displays. The RCA lead is one of the most visually identifiable video cables. It was also the primary connection for many games consoles, including the Nintendo Wii.
The name doesn't refer to the technology itself, but to the company that popularized it, the Radio Corporation of America. The red and white connectors provide audio, while the yellow offers a single channel composite video. When used together, the three cables transmit stereo audio with video up to i or i resolution. DVI connections can transmit uncompressed digital video in one of three different modes:. Single-link can support x at 60Hz while adding a second digital transmitter for dual-link means the resolution can be increased to x at 60Hz.
This proprietary interface was created by a group of electronics firms, including Sony, Sanyo, and Toshiba. There have been many iterations of the HDMI standard to accommodate advances in technology. The most recent is HDMI 2. Importantly, HDMI cables are backward compatible, so that you can use a cable with the latest features on older devices. The reverse is also true, meaning you can use an older cable on devices made to the HDMI 2.
