INRIKS EX4076KVM 4K HDMI KVM twisted-pair extender review.

Feature description

The INRIKS EX4076KVM is a transmitter and receiver kit that allows HDMI and USB signals to be transmitted over twisted-pair cables for up to 230 feet.

Specsheet claims the maximum supported video resolution is 4K at 60 Hz.

The transmitter has an HDMI pass-through output port. It can help connect a nearby TV or monitor.

The receiver has a digital S/PDIF output for connecting an audio system.

The manufacturer does not specify the version of the USB standard. We assume this is USB 1.1, intended for connecting low-speed devices like a regular keyboard and mouse. So, the webcam most likely will not work with such an extender, but we will check it anyway.

Let's take a closer look at what's in the box and how everything connects together.

Visual overview

As usual, INRIKS ships out the EX4076KVM kit in a gray cardboard box with a brief description on a sticker.

Inside the box, one finds the transmitter and the receiver neatly tucked in soft-touch plastic baggies. Those are rare for INRIKS packaging, usually saved for a higher-level lineup of extenders.

Under the plastic tray, there are two PSUs, a USB cable, and a set of mounting brackets with a bunch of screws.

So the full kit of the INRIKS EX4076KVM is:

     • Transmitter unit - 1 pc      • Receiver unit - 1 pc      • DC 5V/2A - 2 pcs      • USB Cable - 1 pc      • Mounting brackets - 8 pcs      • Screw - 18 pcs      • User manual - 1 pc

The transmitter and the receiver are both medium-sized, not compact, but feel solid in your hand. It's easy to spot high manufacturing quality right away. The entire case is made with minor grooves for better heat dissipation.

One side of both the transmitter and the receiver has the same set of interfaces, left to right:      • a pair of LED indicators for USB (KVM) signal transmission and reception      • Reset button      • RJ45 port for twisted pair connection      • LED power indicator

On the opposite side of the transmitter, left to right:      • power connector DC 5V-12V      • HDMI output for a local TV      • HDMI input for connecting a video source, PC, or DVR      • USB port for connecting to a video source

The opposite side of the receiver, from left to right:      • DC 5V-12V power input      • digital audio output (S/PDIF)      • HDMI output for a TV      • two USB ports for a keyboard and a mouse

One can call it just a standard set of interfaces, except for the loop-out HDMI on the transmitter and S/PDIF digital audio output on the receiver.

We have already covered the HDMI loop-out function in a separate post. It is basically a 1 to 2 HDMI splitter built into the transmitter.

It can connect a reference monitor, displaying the video identical to that transmitted over a twisted-pair cable to another room. Suppose you want to stream the same video simultaneously to both the remote room and the room with the video source (PC or DVR). In that case, you can do it easily with no external HDMI 1-to-2 splitter or additional cables needed.

As for the S/PDIF audio output of the receiver, this option will be of little use to anyone connecting an HDMI KVM extender to a DVR. Although it might be helpful to someone.

The sides of the housing have mounting holes for screws. The possibility of adding the brackets and the fact that they are included are undeniable advantages of this kit. With them, you can securely fix the transmitter and receiver to horizontal and vertical surfaces.

The holes allow the mounting brackets to be positioned in two planes, as shown:

The first option of bracket placement is used to secure the device to a horizontal or vertical surface by the majority. However, some professionals will be very grateful for the ability to install brackets using the second option.

We've already said that the transmitter and receiver feel substantial and well-made. All ports fit perfectly into the cutouts in the case. Having unscrewed the front panel, the thickness of the case immediately caught one's eye; no expense was spared on it. Most likely, it is made of aluminum alloy. The circuit board is securely seated in its guiding grooves and does not wobble.

The front face of the board is made neatly without any visible flaws. The downside is a downside (pun intended). We've found flux stains around bigger components like connectors. At this time, we can consider this a signature feature of INRIKS equipment. Although it is unlikely that this will somehow affect the operation of the kit, this is the voice of an inner perfectionist in me :)

Wiring up and testing

For the first test, we decided to use the setup from the manual. The only exception was that we did not connect an external speaker system to the S/PDIF port.

We connected the transmitter and the receiver with a 230-foot-long CAT6 twisted pair cable. This is the maximum length, according to the manual.

We've connected the laptop to the transmitter with HDMI and USB cables. Additionally, we've hooked up a reference monitor to the transmitter to test the Loop-Out HDMI function.

We've connected a second remote monitor, keyboard, and mouse to the receiver.

It took a few seconds after the startup for the devices to pair. The laptop began playing video on the local control and the remote displays. We did not encounter any visible delays. Just to be sure, we've repeated the tests with Online Stopwatch. If there even was a delay in video transmission, it was definitely under 1 millisecond.

We had no problems with the quality of the video.

The remote mouse and keyboard also worked without delays or issues.

The point is that we did not feel that the laptop and the monitor, mouse, and keyboard were 230 feet of twisted-pair cable away from each other.

The next stage was connecting a webcam instead of a keyboard and mouse. The camera did not turn on upon connection.

This is predictable; we've already mentioned that there is a difference between an HDMI KVM extender over a twisted pair and an HDMI USB extender over a twisted pair. KVM extenders usually support just the USB 1.1 interface and work only with HID-class devices, the most common of which are keyboards and mice. Therefore, manufacturers often use the abbreviation KVM (keyboard, video, mouse) to emphasize the intended use case and limitations.

Kinda verdict

In our humble opinion, the INRIKS EX4076KVM is an excellent 4K HDMI KVM (keyboard, video, mouse) extender kit over twisted pair cable up to 230 feet. It is perfect for home CCTV applications. For example, your recorder is located in the attic, but you want to access it from a room downstairs; the only thing you have to do in this case is run a single piece of CAT6 twisted pair cable.

Choosing the right KVM switch for your setup can significantly enhance productivity, reduce clutter, and optimize resource utilization. In this comprehensive guide, we'll explore the key factors to consider when selecting a KVM switch to ensure it seamlessly integrates into your unique environment.

Before delving into the selection process, it's essential to grasp the fundamentals of KVM switches. KVM stands for Keyboard, Video, and Mouse – these switches' primary peripherals. KVM switches come in various forms, catering to diverse needs, from small home office setups to sprawling data centers.

Start your journey by understanding the types of KVM switches available. The two main categories are Desktop KVM switches, and Rackmount KVM switches. Desktop switches are compact and suitable for personal or small-scale use, while Rackmount switches are designed for larger setups like data centers, allowing for centralized control.

The number of ports on a KVM switch is a critical factor. Each port represents a connection for a computer or server. Consider your current setup and potential future expansion. It's advisable to choose a switch with more ports than you currently need to accommodate future growth.

Ensure the KVM switch is compatible with the devices you plan to connect. Check for compatibility with operating systems, video resolutions, and peripheral types. Universal compatibility ensures a smooth integration into your existing infrastructure.

The video resolution supported by the KVM switch is crucial, especially if you work with high-definition displays or multiple monitors. Opt for a switch that supports the maximum resolution required by your monitors to maintain optimal visual quality.

Consider the type of connectivity your peripherals use. Most modern KVM switches support USB connections, while older systems may require PS/2 connections. Ensure that the switch accommodates the interface of your keyboard, mouse, and other peripherals.

Evaluate the user interface of the KVM switch. Some switches feature on-screen displays (OSD) that simplify the navigation between connected devices. An intuitive interface can enhance user experience and efficiency.

Hotkey functionality allows users to switch between connected devices quickly. This feature is particularly useful in environments where swift transitions are essential. Check if the KVM switch supports customizable hotkeys to align with your preferences.

Security is paramount, especially in enterprise environments. Look for KVM switches with advanced security features such as password protection, user authentication, and encryption to safeguard sensitive data and prevent unauthorized access.

Ensure that the KVM switch supports audio transmission if audio is integral to your work or entertainment setup. This feature is crucial for multimedia applications and collaborative work environments.

Future-proof your setup by choosing a KVM switch that allows for easy expansion. Some switches support daisy-chaining, enabling the connection of additional switches for scalability.

Remote management capabilities become invaluable in scenarios where physical access to the KVM switch is limited. Look for switches with IP-based or web-based remote management features for convenient control from anywhere.

Invest in a KVM switch from a reputable manufacturer known for reliability and durability. A robust switch ensures stable operation and longevity, minimizing the risk of disruptions to your workflow.

While cost should not be the sole determining factor, finding a balance between features and budget is essential. Evaluate the KVM switch's long-term benefits and cost-effectiveness for your specific requirements.

Boost Your Gameplay with Samsung’s 55-Inch Curved Monitor

The current 55-Inch Curved Monitor Samsung Odyssey Ark monitor will be discontinued in favor of the Odyssey Ark 2nd Gen, which will have an MSRP of $3000 and is referred to as Ark 2 for short. This news was released by Samsung. We are making the assumption, given that this is a refresh, that the first Ark had a satisfactory amount of success to justify a sequel. Because this update is around $500 less than its predecessor, the Ark 2nd Gen may possibly be able to appeal to a larger audience; yet, what exactly sets it apart from its predecessor in the first place?

The 55-Inch Curved Monitor screen size, the 4K resolution, and even the “Multi View” function are all same between the Samsung Odyssey Ark and the Samsung Odyssey Ark 2nd Generation. Both displays use the same underlying VA panel with per-pixel dimming for optimum HDR10 playing. A little bit more on that topic is coming up.

This indicates that if you are not interested in one of Ark 2’s extremely particular enhancements over the original Odyssey Ark, you may be better off looking for a cheaper used or refurbished copy of the original Ark. This applies even if you want one of Ark 2’s unique improvements.

Two HDMI 2.1, one HDMI 2.0, and one DisplayPort 1.4 connections replace the Odyssey Ark’s four HDMI 2.1 connectors. HDCP 2.2 is supported by every port.

The Ark 2 comes with a built-in KVM Switch, which makes it easier to operate numerous PCs that are connected to the same Ark display using the Ark’s Multi View feature.

Overall, the modifications are minor. When suppliers are comfortable with designs like these, revisions may lower prices.

The Odyssey Ark monitor was the precursor of the Ark 2nd Gen, and it has many of the same distinguishing characteristics with the newer version of the monitor. You may also use the same tool to change your aspect ratio from 16:9 to 21:9 or lower your monitor’s output from 55 inches to 27 inches, which is more desktop-friendly. Both choices are accessible.

The 55-Inch Curved Monitor unique size, curved form, and versatility are also essential. You can also rotate the display to any angle, including standing portrait, which is great for people distracted by instant messaging and feeds.

How does one control a single DVR from two remote rooms?

We have already covered the topic of connecting a monitor, mouse, and keyboard to a PC (server, laptop, or DVR) at a great distance. The best option is to use an HDMI KVM extender over a twisted-pair cable.

With its help, one can complete the simple task of installing a DVR in one place, a monitor, keyboard, and mouse in another, and controlling the DVR remotely. In other words, using twisted pair cables, one extends HDMI and USB interfaces by 200–300–400 feet.

But what if the person needs to connect two different remote workstations for CCTV operators so that every one of them can see the image from the DVR and control it?

Let's try to solve this problem in practice using HDMI KVM extenders over twisted pair and see if it works out.

Required digression

First and foremost, I'd like to note that HDMI KVM twisted pair extenders come in two main types: 1. The transmitter and the receiver are connected to each other directly by a single piece of network cable. Such setups guarantee almost perfect image quality without any visible video distortion or transmission delays for HDMI and USB signals. 2. The transmitter and the receiver are connected to the local network. Both units encode and decode video signals, which, although just a smidge, negatively affects the image quality and increases the transmission delay, so one can feel a slight lag when using the mouse.

We think it is always better to try to use the first type of extender. Such devices deliver the best user experience of all.

On the other hand, sometimes, running a single dedicated twisted-pair cable between the transmitter and receiver is not at all possible. In this case, your only option is the second type of extender. Obviously, you'll need a LAN connection available on both ends :)

Therefore, we'll experiment with both types of extenders separately.

Extending the HDMI KVM interface to two different spaces with a one-piece twisted-pair cable

To assemble such a system, we used a pair of INRIKS EX4076KVMs. The kit includes a transmitter and a receiver. The INRIKS EX4076KVM can transmit 4K 60 Hz video with USB KVM up to 230 ft.

Thanks to the HDMI pass-through port on the transmitter, we can connect two transmitters, one after another, to the DVR. This way, we don't have to use a splitter to duplicate the HDMI signal.

As shown in the diagram below, we have connected all of our equipment.

Everything started working after powering on the equipment and a little initial delay. This startup delay is for all the video devices to sync. The video quality on the remote monitors was perfect; both mice worked simultaneously. We consider this test to be passed.

Extending the HDMI KVM interface to two different spaces over the LAN

We took two HDMI KVM extenders for this case over LAN INRIKS EX2073KVM. The kit extends 1080p 60Hz video and USB KVM over a network cable for up to 390 ft

It should be noted that the kit uses an IP network, so we can use LAN switches to increase the transmission distance even further. For example, when using a single network switch, the distance will be "up to 330 ft." — "LAN switch" — "up to 330 ft." 

Another advantage of HDMI extenders over LAN is streaming the signal from a single transmitter to multiple receivers ("one-to-many connection" in the manual). All the receivers will get the same picture from the transmitter.

We'll try to make use of this feature in our scheme. That means we'll need just the receiver from the second INRIKS EX2073KVM kit.

The manufacturer also states that although many EX2073KVM receivers can be present on the LAN, the mouse should be connected to only one of the receivers at any given time; the remaining ones are just there to show the image. We will check whether this claim is valid.

We have connected all of our equipment as shown in the diagram below and, according to the manufacturer's recommendations, just one mouse.

There is a short pause after powering up to sync all the devices, and everything's working as intended.

We've noticed a small drop in image quality on the remote monitors. For a video stream, it is fine. Still, when displaying static text or menus, it is very easy to notice a slight color bleeding around those areas.

The mouse movements are a bit laggy, which should be nothing critical for operating a DVR. Using a mouse is a rare occasion for such systems.

Next, according to the manual, we disconnected the mouse from the first receiver and plugged it into the second one. The mouse initialized and started working almost immediately.

However, we decided to connect the second mouse to the system. Oddly, both mice worked perfectly fine at the same time. It could be due to no USB keyboards connected to our system. Still, keyboards are unnecessary to work with our recorder.

We decided to experiment further and connected the keyboard to one of the receivers. The video continued to be displayed on the monitors, but the keyboard and both mice stopped working completely. To fix this and have at least one mouse working, we had to disconnect all USB devices from the receivers and then reconnect the mouse.

So connecting more than one mouse to the system is a bad idea overall, as the number of receivers could be 2, 3, 5, 10, or more. Connecting two mice can turn out fine, but that's more like an exception.

We also found out that for this second connection scheme, it is better to use wired mice. As one physically disconnects them from the receiver's USB port, they stop sending data. For a wireless mouse, even if it is turned off with the switch, its USB dongle will remain active and send out some data. So, as far as the receiver unit is concerned, the mouse is still connected, so you will have to disconnect the dongle every time and try not to lose it between sessions.

Conclusion

It is better to avoid LAN solutions when connecting two remote workstations for CCTV operators using extenders over twisted-pair cables. If you can put up with the decreased video quality and a slight mouse lag, the inconvenience of remembering to unplug the mouse every time will annoy the s out of you.

Moreover, you'll have to keep an eye on the system just to never end up in a situation where several USB devices are connected simultaneously and should be unplugged to continue working. In our case, it is a test stand, and all the devices are in the same room; reconnecting USB devices is simple and quick. It will be considerably less fun if the receivers are in different rooms or even on different floors...

As opposed to the latter, INRIKS EX4076KVM is easy to recommend for connecting multiple workstations. It is basically flawless for the task and additionally supports 4K, which could be helpful for CCTV applications.
