There are a few things you'll want to take care of before you deploy your new video extender in your setup.
It’s important to make sure you have everything you will need ahead of time. These items are listed below.
It’s also important to test everything in a simplified setup ahead of time to make sure everything works and that you understand how it works.
In order to set up your video extender, complete the following:
Note: Not all video extenders require external power, or require external power on both ends. Refer to the manual for more information.
Now that you have set up your video extender, you can check that everything is working. You should be able to see your video source's output on the display connected to the video receiver.
If at this point you have further questions regarding a Startech.com video extender, contact our technical support team for further assistance.
Although there are multiple video outputs on certain video extenders at StarTech.com, these do not create independent displays. Instead, the input to the video extenders with multiple outputs gets mirrored or duplicated. This is because video extenders have built-in video splitters to allow for multiple video outputs.
For more information about how mirroring works, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=video#mirror-span-extend.
Note: The ST12MHDLAN can be used to create a video wall which allows for independent displays. For more information about the ST12MHDLAN, refer to the product page for ST12MDHLAN: http://www.startech.com/ST12MHDLAN.
You should only use video converters and extenders if it is absolutely necessary to do so. In many cases, most video converters and extenders are not necessary if you purchase the correct cable.
The following table lists the maximum length of cable for common video standards.
|Video standard||Maximum length|
|DisplayPort||50 ft. (15.2m)|
|HDMI||50 ft. (15.2m)|
|DVI||50 ft. (15.2m)|
|VGA||200 ft. (71m)|
Note: StarTech.com offers cables longer than what is listed above, including active cables, which typically include built-in active signal boosters that allow for longer cables. Active cables are specifically designed to exceed the suggested maximum lengths and are tested at the listed specifications (for example, the maximum listed resolution).
Video adapters passively adapt a cable from one connector type to another. Video adapters do not change the signal type, or change the video standard.
Examples of common applications for adapters include the following:
DVI-I to VGA
RCA to BNC
Mini DisplayPort to DisplayPort
Couplers (female to female, or male to male)
Note: You can use a coupler to extend a cable for a short distance. However, each coupler that you use can introduce signal loss, which degrades the signal quality.
Video converters actively process and change the signal type from one video standard and convert it to another standard. They are typically used to convert digital to analog and vice versa, but can be used to convert a digital signal to another digital video standard (for example, HDMI to DisplayPort).
Video converters work over short distances from the source to the destination: up to 15 feet or 3 meters.
Video extenders convert an input signal to a higher voltage for transmission over longer distances and then convert the input signal back to the original video standard. The input and the output signal will match on a video extender, as the same video standard is maintained end-to-end. If a cable is extended with adapters or converters, the signal quality degrades.
Note: For more information on using a video adapter or converter with a video extender, see the following FAQ: http://www.startech.com/faq/video_signal_converters_convert_then_extend.
If you need to use a video extender with a video adapter or converter, you should position the adapter or converter as close to the video source as possible. For example, if you need to take a VGA signal from a computer and send it 200 feet to an HDMI® projector, you should convert the signal from VGA to HDMI and use an HDMI extender.
Note: For more information on when to use cables or extenders, see the following FAQ: http://www.startech.com/faq/video_signal_converters_when_to_convert.
No, this device is designed to be a point-to-point solution using networking cabling only.
This device outputs a VGA signal. If you have a display or video destination that uses another type of video connection, there are ways that you can convert the video signal or connection. These options are outlined below and organized by the target connection.
|Target connection||First conversion||Second conversion (if required)|
|DVI-D||VGA to HDMI: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=VGA&filter_AVOUTPUT=HDMI.||HDMI to DVI-D: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=VGA&filter_AVOUTPUT=HDMI.|
|DVI-I||VGA to DVI-I: https://www.startech.com/Cables/Audio-Video/Video-Adapter/DVIVGA/.||N/A|
|DisplayPort||VGA to HDMI: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=VGA&filter_AVOUTPUT=HDMI.||HDMI to DisplayPort: https://www.startech.com/AV/Converters/Video/?filter_AVINPUT=HDMI&filter_AVOUTPUT=DisplayPort.|
Note: You might need to use more than one converter as part of your solution; however, you should try to use the least number of converters and cables to connect your source and destination. If you have the option to convert to multiple target video connections, choose the option that requires the fewest number of conversions.
When you convert from VGA to DVI, you need to know if you are converting to a DVI-I or a DVI-D connection. For more information about how to identify the type of connection that you need, refer to the following FAQ: https://www.startech.com/faq/video_signal_converters_dvi_interface.
You also need to know which form of DVI that you are using, because DVI-I supports both analog (VGA) and digital (HDMI) signals, while DVI-D only supports digital (HDMI) signals.
Note: Certain devices may have a DVI-I connection but only support DVI-D signaling. It is important to verify that your DVI-I device supports DVI-I signaling.
This device has a VGA input port. If you have a video source that uses another video connection, there are options available to convert the video signal or connection. These options will be outlined below for each video source connection.
DVI-I to VGA: https://www.startech.com/DVIVGAMFBK.
DisplayPort to VGA: https://www.startech.com/AV/Displayport-Converters/DP-VGA/.
When you convert from DVI to VGA, you need to know if you are converting from a DVI-I or a DVI-D connection. For more information about how to identify the type of connection that you have, refer to the following FAQ: https://www.startech.com/faq/video_signal_converters_dvi_interface.
You also need to know which form of DVI that you are using, because DVI-I supports both analog (VGA) and digital (HDMI) signals, while DVI-D only supports digital (HDMI) signals. Some DVI-I connections only support DVI-D signaling. In this case, you must use a DVI-D to VGA converter.
