Avoid unnecessary cable stress. Keep network cable runs as straight as practical and avoid tight bends, excessive coiling, or cable damage. Reduce electrical interference. Route network cables away from sources of electromagnetic interference (EMI), such as fluorescent lighting, motors, transformers, and power cables. Provide proper grounding. Ensure that connected equipment is properly grounded to help reduce electrical noise and improve system stability. Following these recommendations helps maximize video quality, maintain reliable HDCP communication, and improve the overall performance of an HDMI extender installation.

I want to use multiple transmitters on a network. How should I set the dip rotary switches?
If you wish to use multiple transmitters on a network, each Transmitter will need to be set to a different dip rotary switch value (0-9, A-F). Each Receiver will then need to match the transmitter it will be associated with. Note: changes to the dip rotary switches take effect after the transmitter(s) and receiver(s) are power-cycled.

I’m not seeing a video signal on the display. How do I fix this?
The power adapter may not be connected at the correct unit or may not be connected at all. Please check your product manual to see where your power adapter has to be positioned. An adapter to another video signal may be connected to the Transmitter or Receiver unit. Please avoid any converters for the initial setup. The Cat 5 or 6 cable coming from the transmitter or receiver unit may be connected to a network switch. Some of our video extenders will work in this configuration, but others will not. Please check your product manual to see if your model can be used connected to an IP network. For the initial setup, avoid connecting the Cat 5 or 6 cables to any network switch, hub, or router. The category of Unshielded Twisted Pair (UTP) cables may not meet StarTech.com’s requirements. Ensure at least Cat 5, 5e, or six cables are used, and they have eight wires. Some Cat 5 cables only have four wires. If using Cat 6 cables, be aware they have more twists per foot, so you may have to use shorter cable lengths if using Cat 6 cabling between your video extenders. Bundling up the UTP cabling connected to the extenders can cause crosstalk, which will prevent the video signal from showing on the display. Unwrapping the cable should resolve this issue.

The video signal is displayed, but the quality is not very good, or the colors are not accurate. How do I fix this?
Please check to see if your model has an adjustable Gain dial on the remote unit. If it does, use it to adjust the color until it is acceptable. Replace the VGA cable with a higher quality cable like StarTech.com’s MXT101MMHQ.

Everything is hooked up but nothing is working. What should I do?

When should I use a longer video cable instead of a video extender?
Use a longer video cable whenever possible; use a video extender only when the required distance exceeds the reliable limits of standard or active cables. Explanation: Direct cabling is the preferred method for video connections because it maintains signal integrity and reduces complexity. Standard maximum cable lengths for common video signals are: Video standard Maximum length DisplayPort 50 ft. (15.2m) HDMI 50 ft. (15.2m) DVI 50 ft. (15.2m) VGA 200 ft. (71m) Active cables can extend these distances by incorporating built-in signal amplification and are designed to exceed standard length limits while maintaining specified performance. Video extenders are used when cable length requirements exceed what passive or active cables can reliably support. Extenders transmit the signal over longer distances by boosting and then restoring it, while maintaining the same video standard from input to output.

What is the correct way to convert and extend a video signal?
Convert the video signal as close to the source as possible, then extend the converted signal using a compatible video extender. Explanation: When both signal conversion and extension are required, the conversion should occur before the signal is extended. Placing the video converter near the source device ensures the signal is converted to the desired format early, which improves compatibility and signal stability over long distances. After conversion, a video extender should be used to transmit the signal over the required distance while maintaining the same video standard end-to-end. For example, to send a VGA signal to a distant HDMI display, first convert VGA to HDMI at the source, then use an HDMI extender to carry the signal to the display. This approach minimizes signal degradation and ensures the extender operates with a consistent signal type throughout the transmission.

What is a StarTech.com HDMI over IP video extender, and what requirements must my network meet for it to work?
A StarTech.com HDMI over IP video extender transmits HDMI video and audio over an IP network, and it requires sufficient network bandwidth, IGMP support, and standard Ethernet connectivity to function correctly. Explanation: A StarTech.com HDMI over IP video extender converts HDMI video and audio signals into IP packets and distributes them across an existing Ethernet network. This enables scalable video distribution, including video wall configurations and multi-display setups, unlike point-to-point extenders that rely on direct cabling or wireless links. To determine compatibility, the network must meet the following requirements: Ethernet connectivity and distance: Each transmitter and receiver must connect to a network switch or router using standard Ethernet cabling, with a maximum distance of 100 meters per device-to-switch link. Network bandwidth capacity: Video streams consume network bandwidth. For 1080p at 60 Hz, calculate required bandwidth as: (number of transmitters + number of receivers) × 45 Mbps. For example, 1 transmitter and 4 receivers require approximately 225 Mbps. A Gigabit Ethernet network is recommended to maintain performance and stability. Scalability limits: The StarTech.com ST12MHDLAN supports up to 16 transmitters, depending on available network bandwidth. The number of receivers is also constrained by total network capacity. IGMP support: The network switch or router must support Internet Group Management Protocol (IGMP) to efficiently manage multicast traffic between transmitters and receivers. C ontrol software compatibility: Supported StarTech.com video extender models include a free management application (iOS, Android, and Google Chrome) for automatic device detection, video wall configuration, and source switching. Optional USB extension: Some StarTech.com HDMI over IP video extender models also support USB signal extension alongside video and audio distribution. Meeting these requirements ensures reliable operation, predictable performance, and scalable deployment across multiple displays and endpoints.

What are the network and setup requirements for using a StarTech.com video extender in a video wall configuration?
A StarTech.com video extender requires a managed network switch with IGMP support, sufficient network bandwidth, and proper multicast configuration to operate in a video wall setup; unmanaged switches do not support video wall configurations. Explanation: A StarTech.com video extender can operate in point-to-point, mirror, or video wall configurations, but video wall setups have specific network and configuration requirements: Managed switch with IGMP support: A managed network switch that supports Internet Group Management Protocol (IGMP) is required for any video wall or multi-transmitter setup. IGMP controls multicast traffic so that video streams are delivered only to intended receivers. Without IGMP, video wall configurations will not function correctly. Multicast traffic management: IGMP-enabled switches automatically detect and manage multicast group memberships between transmitters and receivers. During initialization, the switch may take up to one minute to learn the network topology and optimize traffic routing. Network bandwidth requirements: The network must have enough capacity to handle all active video streams. Insufficient bandwidth can cause dropped frames, latency, or connection timeouts during video wall operation. Unmanaged switch limitations: Unmanaged (plug-and-play) switches do not support IGMP and cannot control multicast traffic. They are limited to single-transmitter mirror mode only and will cause network congestion or timeouts if used for video wall configurations. Point-to-point configuration: A direct Ethernet connection between one transmitter and one receiver does not require a network switch. Both units must have matching thumbwheel settings to communicate on the same default network. Video wall scalability: Multiple transmitters and receivers can be combined in a video wall layout only when the network infrastructure supports IGMP and sufficient bandwidth for all streams. These requirements ensure reliable multicast video distribution, prevent network flooding, and enable stable, scalable video wall deployments using StarTech.com video extenders.

Is a StarTech.com video extender compatible with set-top boxes, and what are the requirements?
Yes, a StarTech.com video extender is compatible with set-top boxes if the set-top box is HDCP-compliant and allows intermediary devices between the source and display; otherwise, it will not work. Explanation: A StarTech.com video extender can transmit video from a set-top box to a remote display, but compatibility depends on the set-top box’s signal protection and connection requirements. HDCP compliance required: The set-top box must support High-bandwidth Digital Content Protection (HDCP) in a way that allows video output through external devices. If HDCP implementation blocks transmission through intermediary hardware, the video extender will not display content. Intermediary device support required: The set-top box must allow a device, such as a video extender, to be placed between the source and the display. Some set-top boxes require a direct HDMI connection and will not output video through any intermediate device. If the set-top box does not meet both requirements, the StarTech.com video extender will not function correctly with that device.

How many transmitters and receivers can I connect to a StarTech.com video extender, and what are the limits?
A StarTech.com video extender supports up to 16 transmitters, and the number of receivers is not fixed but is limited by available network bandwidth. Explanation: A StarTech.com video extender allows multiple transmitters and receivers on the same network, but overall system capacity depends on both device limits and network performance. Maximum transmitters: The system supports up to 16 transmitters. This is a hard limit, but actual performance depends on available network bandwidth. Receivers are bandwidth-limited: There is no fixed maximum number of receivers; however, each receiver adds additional bandwidth usage. The total number of receivers is therefore constrained by network capacity. Bandwidth impact: Each active transmitter and receiver contributes to total network load. If bandwidth is insufficient, video performance may degrade, and other network devices may be affected. A StarTech.com video extender system will not scale reliably beyond network capacity, even though receiver count is not explicitly capped.

What is IGMP, and why is IGMP required for a StarTech.com video extender?
IGMP (Internet Group Management Protocol) is a network protocol that controls multicast traffic, and it is required for a StarTech.com video extender to ensure video streams are sent only to intended receivers instead of all devices on the network. Explanation: Internet Group Management Protocol (IGMP) is used by network devices, such as switches and routers, to manage multicast group membership. It ensures that network traffic is delivered only to devices that request it, rather than broadcasting it to every device on the network. A StarTech.com video extender relies on multicast transmission to distribute video streams efficiently across multiple receivers. IGMP is required for the following reasons: Targeted video distribution: IGMP ensures that video streams are sent only to designated receivers, not to all devices on the network. Reduced network congestion: Without IGMP, the video extender would flood the network with multicast traffic, sending video data to every connected device. Network performance protection: Excessive unnecessary traffic can degrade performance for other devices and applications on the network. If IGMP is not supported or enabled, a StarTech.com video extender may cause network congestion, reduced video performance, or failure to operate correctly in multi-device setups.

Can I mix or use ST12MHDLAN and ST12MHDLANU transmitters and receivers together?
No, StarTech.com ST12MHDLAN and ST12MHDLANU transmitters and receivers are not interchangeable and cannot be used together in the same setup. Explanation: StarTech.com ST12MHDLAN and ST12MHDLANU are separate video extender systems designed with different hardware architectures and communication protocols. No interoperability: Devices from the ST12MHDLAN series cannot communicate with devices from the ST12MHDLANU series. Model-specific compatibility required: Each transmitter must be used only with receivers from the same product model. Mixed systems not supported: Combining ST12MHDLAN and ST12MHDLANU devices in a single deployment will result in system failure or no signal transmission. To ensure proper operation, all transmitters and receivers in a StarTech.com video extender setup must belong to the same model series.

How much video delay or latency should I expect when using a StarTech.com video extender?
It depends; the video delay (latency) of a StarTech.com video extender cannot be fixed or guaranteed and varies based on network conditions and setup. Explanation: Video latency when using a StarTech.com video extender is influenced by multiple factors within the network and deployment environment, so it cannot be defined as a specific value or milliseconds range. Network bandwidth and congestion: Limited bandwidth or heavy traffic increases video delay. Network hardware performance: Switches, routers, and cabling quality directly affect transmission speed and latency. Number of transmitters and receivers: More connected devices increase total network load and can introduce additional delay. Network configuration and topology: Complex routing, multicast handling, and infrastructure design can impact latency. Because these variables differ across environments, a StarTech.com video extender may exhibit different levels of delay or lag in each installation, and latency cannot be accurately predicted in advance.

How can I connect this HDMI output to a VGA, DVI, or DisplayPort display?
An HDMI output can be connected to VGA, DVI, or DisplayPort displays using the appropriate adapter or video converter. The required solution depends on the input type of the display and whether HDCP-protected content is being used. Explanation: This device outputs HDMI video signals. If the display or video destination uses a different connection type, an adapter or active video converter may be required. Common conversion options include: VGA: An active HDMI to VGA converter is required because HDMI uses digital video signaling and VGA uses analog video signaling. DVI: A passive HDMI to DVI adapter or cable can be used because HDMI and DVI share compatible digital video signaling. DisplayPort: An active HDMI to DisplayPort converter is required because HDMI and DisplayPort use different signaling technologies. HDCP Considerations Before converting an HDMI signal, determine whether the source content is protected by High-bandwidth Digital Content Protection (HDCP). HDCP is commonly used by devices such as: Blu-ray players DVD players Streaming devices Gaming consoles If the HDMI source is transmitting HDCP-protected content, conversion to an analog video format such as VGA may not be supported because VGA does not support HDCP. In these situations, video may not display correctly or may not display at all. Best Practices For the most reliable results: Use the fewest possible adapters and converters. Verify the required resolution and refresh rate. Confirm that the converter supports the desired signal direction and video format. Consider HDCP requirements when converting protected content.

How can I connect a VGA, DVI, or DisplayPort video source to this device's HDMI input?
This device features an HDMI input. If your video source uses VGA, DVI, or DisplayPort, you can connect it using the appropriate adapter or video converter. The required solution depends on the video output available on the source device. Explanation: HDMI inputs require an HDMI signal. Video sources that use VGA, DVI, or DisplayPort may require signal conversion before they can be connected to this device. Common conversion options include: VGA source: Use an active VGA-to-HDMI converter because VGA uses analog video signaling and HDMI uses digital video signaling. DVI source: Use a passive DVI-to-HDMI adapter, cable, or converter. DVI and HDMI use compatible digital video signaling, making conversion straightforward in most applications. DisplayPort source: Use either a passive or active DisplayPort-to-HDMI adapter, depending on the capabilities of the DisplayPort source. DisplayPort Passive vs. Active Adapters When converting from DisplayPort to HDMI, the correct adapter type depends on whether the DisplayPort source supports DisplayPort Dual-Mode (DP++). Passive adapters require a DisplayPort Dual-Mode (DP++) source. Active adapters work with both standard DisplayPort and DisplayPort Dual-Mode (DP++) sources. If you are unsure whether the source supports DisplayPort Dual-Mode, consult the device documentation or use an active adapter for broader compatibility. For more information about converting DisplayPort video signals, refer to the following FAQ: https://www.startech.com/faq/DisplayPort_Converter_DP_Multi_Mode .
