How Far Can You Extend 4K HDMI over HDBaseT? 70m, 100m, and 150m Compared

The label alone that says how far the cable is able to transmit the 4K video signal does not give you any information about the distance. The resolution, the refresh rate, the chroma format, the bandwidth, the operation mode, and the type of cable itself play their role when defining the reach. We offer HDBaseT transmission for distances 70m, 100m, and 150m, but the right comparison starts with the format of video first.

What HDBaseT Distance Ratings Actually Mean

A 70m, 100m, or 150m rating usually describes the maximum transmission distance under a defined signal condition. Don’t read it as a universal distance for every resolution the extender supports.

The difference is particularly important in 4K projects. A 70m-class system may transmit 1080p for the full 70m but carry 4K for only 40m. Selected 100m systems can transmit 4K60 for 100m. In the 150m class, relevant models transmit 4K60 for 120m and reach 150m with 1080p.

Buyers should therefore ask two separate questions: what is the maximum distance, and which signal format can travel that distance? Combining these questions prevents a 1080p distance figure from being applied incorrectly to a 4K installation.

How Resolution Changes the Available Distance

Higher resolution and refresh-rate requirements change the applicable transmission specification. A system designed for 4K30 is not automatically suitable for 4K60, while support for 4K60 does not confirm that the signal can travel the product’s full advertised distance.

4K30 and 4K60 Require Different Specifications

The 70m-class iTrans E70N and E70C models support 4K30 video. They can send this signal up to 40m using a CAT6 cable. Both devices rely on HDMI 1.4 technology with a 10.2Gbps bandwidth. Meanwhile, the B70S supports HDMI 2.0b and 18Gbps bandwidth. It handles video up to 4K60 4:4:4. However, its official distance limit stays at 40m for that specific 4K60 format.

Certain 100m models shift the overall planning range. The E100V3K and E100TR offer support for HDMI 2.0b and 18Gbps bandwidth. They allow uncompressed 4K60 4:4:4 transmission up to 100m. These strong specifications make the 100m class highly relevant. They are ideal when a project demands both maximum distance and a high-bandwidth 4K signal.

1080p Can Use the Longer Distance Rating

A lower-resolution signal can travel farther on several models. The E70N, E70C, E70S, and B70S reach 70m with 1080p while their specified 4K distance is 40m. The E150CG, E150SK, and E150U2 extend 1080p to 150m but carry 4K60 4:4:4 to 120m.

This distinction also applies to Long Reach Mode. The E100HCU carries 4K60, 4K30, or 1080p up to 100m in standard mode. Its Long Reach Mode extends a 1080p 8-bit signal to 150m; it does not extend 4K60 to 150m.

Comparing 70m, 100m, and 150m HDBaseT Extenders

The following table shows how distance class, video format, and representative models relate within the available range.

When a 70m-Class Extender Fits the Project

A 70 meter extender can be used when the actual cable distance is not more than 40 meters. It can also be used when a 1080p signal needs to travel up to 70 meters. However, the decision will depend on the required version of HDMI, bandwidth, resolution and auxiliary signals.

There is a big difference between the models. The E70N and E70C models are able to support 4K30 via HDMI 1.4 and 10.2 Gbps bandwidth. The B70S model supports 4K60 4:4:4, HDMI 2.0b, 18 Gbps, HDR pass-through, bidirectional IR and RS-232 and PoC.

What the 100m Class Adds

The solution of the 100m class can transfer 4K60 from one end to another within 100 meters. Models such as E100K, E100V3K, E100HCU, and E100TR can transfer video in 4K60 4:4:4 format with 18Gbps bandwidth.

Difference among models is better made based on signal requirements rather than distances. Based on which model is selected, the solution may be able to have features such as USB 2.0, USB KVM, IR, RS-232, Ethernet, Power over Cable, ARC or eARC, EDID management, HDMI loop-out or USB-C input. For instance, the E100HCU has the capability to receive HDMI and USB-C inputs.

What the 150m Class Delivers

A 150m-class label does not mean 4K60 at 150m. The E150CG, E150SK, and E150U2 transmit 4K60 4:4:4 up to 120m and 1080p up to 150m. The E150CL reaches 150m with 1080p but has no documented 4K60 transmission distance.

Functions also vary within this distance group. The E150CG provides bidirectional IR and RS-232. The E150SK adds USB KVM pass-through, while the E150U2 supports USB 2.0 for touch control, USB cameras, microphones, and speakerphones. All four E150 models listed in the comparison require the transmitter and receiver to be used as a pair.

Match the Category Cable and Operating Mode

Cable requirements must be checked against the exact model. The E70N specifies different results for CAT6 and CAT5e: up to 70m for 1080p and 40m for 4K30 on CAT6, compared with 60m for 1080p and 35m for 4K30 on CAT5e.

Selected 100m systems specify CAT6A or CAT7 for their full transmission distance. The E100K and E100HCU, for example, document 100m transmission over a single CAT6A/7 cable. The E150SK specifies a single CAT6 cable for 150m at 1080p or 120m at 4K60 4:4:4.

The operating mode must be confirmed at the same time. Standard and Long Reach modes can produce different distance figures, but the longer mode may support a lower video format. A quotation request should therefore state both the installed cable and the required resolution.

Distance Is Only One Part of System Selection

An extender can meet the required cable length and still lack an essential project function. Professional systems may need to carry USB, KVM, IR, RS-232, Ethernet, audio return, or power together with HDMI.

A buyer preparing a technical inquiry should provide:

• Required resolution, refresh rate, and chroma format
• Exact point-to-point cable distance
• Installed or planned category cable
• HDMI and HDCP requirements
• USB, KVM, IR, or RS-232 requirements
• ARC, eARC, or separate audio requirements
• PoC requirements
• Wall-plate or box-type installation preference
• Need for paired units or separately usable devices

These details create a more reliable basis for model comparison and quotation than a request for a “100m 4K extender” without a complete signal specification.

Plan the Required Signal Before Choosing the Distance

The practical answer is clear: a 70m-class extender generally covers 4K up to 40m, selected 100m models carry 4K60 up to 100m, and selected 150m models carry 4K60 up to 120m or 1080p up to 150m. At INFOBIT, we match the distance figure with the complete video, cable, USB, control, audio, and power requirements.

সাধারণ প্রশ্ন

Can a 70m HDBaseT extender transmit 4K for the full 70m?

This is not true in every scenario. The E70N and E70C manage 4K30 up to 40m. They also handle 1080p up to 70m over CAT6. The B70S handles 4K60 4:4:4 up to 40m and 1080p up to 70m. The WP70HBC operates differently. It transports 4K60 4:4:4 up to 40m. Alternatively, it pushes 4K30 4:4:4 up to 70m using CAT6A or better cables.

Which models support 4K60 transmission up to 100m?

The verified range features the E100HC, E100K, E100V3K, E100HCU, and E100TR. Your final model selection must also factor in other needs. Consider your USB, KVM, USB-C, ARC/eARC, Ethernet, control, and PoC requirements.

Is 4K60 possible at 150m with HDBaseT extender?

In regards to the aforementioned 150m products, 4K60 is not available within 150m range for those devices. According to the specifications of the E150CG, E150SK and E150U2, 4K60 4:4.

What information is needed for an accurate quotation?

You must share the target resolution, refresh rate, and chroma format. Also include the cable distance, category cable type, and source or display connections. Mention any USB, KVM, audio, control, or PoC features you need. This specific information helps pinpoint a technically sound transmitter and receiver setup prior to pricing.
