Frequently Asked Questions
What is a video distribution amplifier?
A video distribution amplifier is a device that takes one video source and sends it to multiple displays while helping preserve signal quality. Unlike a simple passive splitter, it actively manages the signal so the image remains more stable over longer cable runs and across multiple outputs.
The Kramer TP-114 is a distribution amplifier designed for computer graphics video and HDTV signals. It accepts one UXGA signal on a 15-pin HD connector, provides one local loop-through output, and sends four identical twisted pair outputs over RJ-45 connections. That makes it useful when one source needs to feed several remote displays in classrooms, presentation rooms, medical environments, security stations, or digital signage setups.
This type of product is best for users who need reliable multi-display distribution rather than a single short cable connection. The main tradeoff is that it is built for VGA and twisted pair distribution, not direct HDMI switching, so it fits legacy graphics and structured cabling systems better than all-digital HDMI-only installations.
What does a distribution amplifier do in a presentation or AV system?
A distribution amplifier sends one video signal to several destinations at the same time while maintaining usable signal strength and consistency. In an AV system, that helps one computer or media source feed multiple displays without the image degrading as quickly as it would with basic splitting.
In practical use, the Kramer TP-114 converts one incoming 15-pin HD computer graphics or HDTV signal into four twisted pair outputs plus one local loop-through output. That means you can keep one nearby monitor connected at the source and extend the same content to four remote endpoints over CAT 5 type cabling. It also includes horizontal and vertical sync polarity switches, which can improve compatibility with certain displays.
This is especially helpful in training rooms, lecture spaces, control rooms, and commercial environments where a single source must be shown in several places. The main limitation is that it is intended for analog computer video distribution over twisted pair, so buyers should confirm that their source, cabling, and receiving equipment match that workflow.
What is the difference between an HDMI splitter and a video distribution amplifier?
The main difference is that an HDMI splitter is typically used to duplicate a digital HDMI signal, while a video distribution amplifier is designed to actively distribute video signals and maintain signal integrity across multiple outputs, often over longer distances or different cabling formats.
The Kramer TP-114 is not an HDMI splitter. It is a twisted pair transmitter and distribution amplifier for computer graphics video and HDTV signals using a 15-pin HD input and RJ-45 outputs. It sends one source to four twisted pair lines and also provides a local loop-through connection. It supports resolutions up to WUXGA and 1080p and can reach up to 320 feet depending on cable quality and resolution.
Shoppers should choose an HDMI splitter if all equipment is HDMI and runs are short. A distribution amplifier like this model is a better fit when the system uses VGA-style computer video, CAT cabling, and remote display locations. The tradeoff is that it serves a more specialized infrastructure need rather than acting as a universal modern HDMI distribution device.
When should I choose a twisted pair video transmitter instead of a standard splitter?
You should choose a twisted pair video transmitter when you need to send video farther than a basic splitter can handle reliably or when your building already uses structured cabling such as CAT 5. Twisted pair systems are often more practical for classrooms, conference spaces, medical rooms, and security environments where displays are spread out.
The Kramer TP-114 is built for exactly that use case. It takes one computer graphics or HDTV source on a 15-pin HD connector and distributes it to four twisted pair outputs over RJ-45, plus one local loop-through output. It supports WUXGA and 1080p, and the system range can reach up to 320 feet, with actual performance depending on resolution and cable quality.
A standard splitter is better for short, simple local duplication. A twisted pair transmitter is better for organized long-run installations. The tradeoff is that you need compatible receiving hardware and proper cabling, so it is best for planned AV systems rather than quick plug-and-play consumer setups.
Is the Kramer TP-114 a good choice for sending one computer signal to multiple remote displays?
Yes, the Kramer TP-114 is a strong fit for that type of setup if your system uses computer graphics video over 15-pin HD and twisted pair cabling. It is designed to take one incoming UXGA signal and create four identical twisted pair outputs, while also providing one local loop-through connection at the source.
That makes it useful when a presenter station, control desk, or central PC needs to feed several remote display points at once. It supports resolutions up to WUXGA and 1080p and can transmit up to 320 feet depending on the signal resolution and cable quality. The compact enclosure also suits rack-adjacent or lectern-mounted installations where space is limited.
This model is best for schools, corporate training rooms, multimedia presentations, and other structured AV environments. Buyers should note that it is intended for VGA-style computer video distribution, not direct HDMI-only systems. If your source devices are modern digital-only outputs, you may need signal conversion or a different category of distribution product.
What maximum resolution does the Kramer TP-114 support?
The Kramer TP-114 supports resolutions up to WUXGA and 1080p. That makes it suitable for many presentation, computer graphics, and HDTV distribution applications where clear detail is needed across multiple displays.
For shoppers, that means the unit can handle higher-resolution content than older basic VGA extenders that may be limited to lower desktop formats. It is intended for environments such as education, commercial presentation spaces, and control applications where computer output needs to be extended to several endpoints over twisted pair cabling.
Actual image performance at the far end still depends on the total cable run, signal quality, and the type of UTP or STP cable used. Higher resolutions generally place more demand on the cable path, so very long runs may require careful system design and compatible receivers. In short, the TP-114 supports WUXGA and 1080p, but buyers should evaluate range and cabling together rather than considering resolution alone.
How far can the Kramer TP-114 transmit video over CAT cable?
The Kramer TP-114 can transmit video up to 320 feet, or 100 meters, over twisted pair cabling. In some cases, greater distances may be possible depending on the signal resolution and cable quality, but 320 feet is the stated system range to plan around.
This makes it practical for larger rooms and facilities where the source and displays are not located near each other. Examples include lecture halls, conference rooms, retail spaces, medical work areas, and security monitoring stations. The unit is compatible with standard UTP or STP cabling such as CAT 5, which helps when using existing structured cabling paths.
The most important tradeoff is that longer distance and higher resolution usually increase the demands on the installation. Better cable and lower signal loss generally produce better results. For buyers comparing options, this model is best suited for systems that need multi-output analog video distribution over meaningful distances rather than short local desktop connections.
What cable types are compatible with the Kramer TP-114?
The Kramer TP-114 is designed to work with standard twisted pair cabling, including UTP and STP cable such as CAT 5. That makes it a practical option for installations that already use structured cabling in walls, ceilings, or equipment pathways.
For many AV buyers, this is one of the key advantages of a twisted pair transmitter. Instead of running multiple long traditional video cables, the system can distribute the signal over common twisted pair infrastructure to compatible receiving endpoints. This is especially useful in schools, offices, healthcare settings, and commercial environments where clean cable management and longer reach matter.
When choosing cable, better construction and proper termination usually improve performance, especially at higher resolutions and longer distances. STP may help in environments with more electrical noise, while UTP is common in many standard installations. The important limitation is that the transmitter should be paired with the appropriate receiving hardware and installed with good cabling practices to achieve the best results.
How does the Power Connect feature work on the Kramer TP-114?
The Power Connect feature allows a single power supply connected to either the transmitter or the receiver to power both units, as long as the devices are within 150 feet, or 50 meters, of each other. This can simplify installation by reducing the number of local power connections needed in the system.
For installers and facility managers, that benefit is especially useful when one end of the link is easy to power and the other is harder to reach, such as behind a display, above a ceiling, or inside a lectern. In those cases, powering one side can reduce clutter and streamline deployment.
The feature is most beneficial in structured AV setups using compatible Kramer transmitter and receiver pairings. The main limitation is the distance condition. The shared power arrangement applies when the two units are within the stated 150-foot range for Power Connect operation. Beyond that, or in non-compatible pairings, separate power planning may be required. It is a practical feature for cleaner installs rather than a substitute for confirming full system compatibility.
Who should buy the Kramer TP-114, and when is it not the right fit?
The Kramer TP-114 is best for users who need to distribute one computer graphics or HDTV source to multiple remote displays over twisted pair cabling. It is a strong fit for classrooms, training rooms, commercial presentation spaces, medical environments, and security applications where one central source must feed several destinations reliably.
Its key strengths are four twisted pair outputs, one local loop-through output, support for WUXGA and 1080p, transmission up to 320 feet, and compatibility with UTP or STP cable such as CAT 5. It also includes sync polarity controls that can help with display compatibility and a Power Connect feature that can simplify powering paired devices within 150 feet.
It is not the right fit if your system is built entirely around direct HDMI distribution or if you need a simple consumer splitter for very short cable runs. It is also less ideal if you do not have compatible receiving equipment for the twisted pair outputs. In short, this is a specialized AV infrastructure product for structured multi-display analog video distribution, not a universal one-cable solution for every source type.
The Kramer TP-114 is a high-performance distribution amplifier engineered for computer graphics video and HDTV signals. It converts an incoming signal from a 15-pin HD connector into four identical twisted pair outputs alongside a local loop-through connection. Designed for demanding presentation and multimedia setups, it supports resolutions up to WUXGA and 1080p across extended transmission distances.
Featuring advanced signal management, the unit includes horizontal and vertical sync polarity switches to enhance display compatibility. Its Power Connect system provides bidirectional power transmission, enabling a single power supply connected to either the transmitter or receiver to run both devices when placed within 150 ft of each other. The transmitter functions reliably over standard UTP or STP CAT 5 cabling.
Built in a compact Kramer TOOLS enclosure, this distribution amplifier achieves transmission ranges of up to 320 ft depending on signal resolution and cable quality. It provides robust signal integrity with low differential gain and phase distortion, making it suitable for long-range graphics distribution in educational, medical, commercial, and security environments.
