The HDN-4 Duo from SmartAVI is built for serious multi‑system workflows. It’s a dedicated 4‑port dual HDMI KVM switch that lets you control up to four different computers from a single workstation, using two HDMI displays and one USB keyboard and mouse. This device is engineered to streamline complex setups where space, efficiency, and reliable peripheral sharing matter most. With USB 2.0 compatibility and audio sharing, you can manage multiple machines without the hassle of swapping cables, reconfiguring audio, or juggling multiple keyboard/mouse sets. Whether you’re coordinating a design studio, IT lab, or a busy production desk, the HDN-4 Duo delivers a crisp, responsive, and scalable solution that fits right into your existing hardware ecosystem.

  • Powerful multi‑host control for a streamlined workflow: The HDN-4 Duo enables you to manage up to four distinct computers from a single position, using two HDMI monitors to display separate outputs and a single set of keyboard and mouse for hands‑on control. This setup eliminates the need to physically move between workstations, saving time and reducing desk clutter. With reliable switching in real time, you can triage tasks, compare results side by side, or run cross‑machine testing without breaking concentration or losing momentum.
  • Dual‑display HDMI performance with integrated audio sharing: This SmartAVI KVM switch is engineered to support dual HDMI monitor setups, allowing you to extend or mirror displays as your work dictates. Paired with a shared audio path, you can route stereo sound from whichever connected computer you’re using to a single speaker system, ensuring you hear alerts, system audio, and multimedia seamlessly across your entire workflow. The result is a cohesive, immersive environment ideal for graphic design, video editing, data analysis, and development work that benefits from multiple viewpoints.
  • Flexible USB 2.0 peripheral sharing at your fingertips: The HDN-4 Duo’s USB emulation capabilities allow you to connect up to two USB 2.0 devices in addition to the keyboard and mouse, and access them across any of the connected PCs. This is a true time‑saver in shared environments—plug in a USB drive for quick file transfers, attach a scan/print device for all systems, or connect specialized peripherals once and reuse them across all machines without replugging cables during each switch. The result is a cleaner desk and a smoother operation for teams that rely on common peripherals.
  • Fast, reliable switching with USB emulation technology: A hallmark of the HDN-4 Duo is its emphasis on immediacy when switching between hosts. USB emulation helps prevent peripheral re‑detection delays and minimizes the disruption that can occur when moving from one computer to another. Whether you’re a software engineer debugging across machines, a video editor swapping between render nodes, or a systems administrator testing configurations, you’ll appreciate the quick, predictable transitions that keep your flow intact.
  • Cross‑platform compatibility with plug‑and‑play ease: The HDN-4 Duo is designed to integrate smoothly into mixed OS environments. It supports common operating systems used in professional settings, including Windows, macOS, and Linux. With straightforward setup and no complex configuration required, you can bring together disparate machines into a unified, manageable workspace. This makes it an ideal solution for studios, IT rooms, classrooms, and collaborative labs where different teams rely on different operating systems yet share the same display and peripherals.

zelda‘s “indoor” ⚽️ ball!
Color: Squeaky Green, Size: Medium Size 2 (6")
zelda loves her soccer ball - because of the fabric “tabs”, and the way she treats her toys, we keep it inside. she loves to place all of her toys and bones on our bed, after they’ve been cleaned. this ball is perfect and soft enough to throw it down our steps, where she will run down, retrieve it, and bring it back to the bed. it arrives deflated and comes with the pump and two needles - the pump is not the sturdiest and felt like it was not inflating, but after only having to reflate it once with a bit of air since receiving it ~5-6 months ago, it still holds up!

Small for a medium
Color: Red-Blue, Size: Medium Size 2 (6"), Color: Red-Blue, Size: Medium Size 2 (6")
I got medium.. and it does not look like a medium ball.. it’s rather small. It’s pretty sturdy and my dogs went crazy for it but it’s definitely not the size I thought it was going to be 😂 my dogs chewed one strap within 5 minutes of having it but they’re dogs and that’s what they do lol. I bought this to be an outside ball for them! It’s pretty light but that’s probably because it’s small. Not soft? But feels like a soccer ball. It also had no smell coming out of the box. Also comes with a pump and an extra thing to put in the ball to pump in case you lose one. I like these balls, I expect them to be chewed up because that’s what I bought them for! Fun for my dogs and they are! But the size… it is not medium and that’s the only reason for 3 stars 😂😂😂 Other then that I recommend, your dog will definitely love this! Inside or outside playing! Alone or with another dog!

Great toy for a GSD
Color: Blue Gray, Size: Extra Large Size 5 (9")
My GSD loves to grab the flaps and shake her head with the ball bouncing of the side of her head. This is her favorite toy. I thought she would puncture it but it has held up great since she likes to grab the flaps rather than biting the ball.

My puppy LOVEs this ball
Color: Glow in the dark I, Size: Medium
I saw someone recommend this ball in a facebook group. I ordered the first one and it is now sitting somewhere under my deck and I can't find it. My dog loved it so much I had to order a second one. I think the fact there are so many tabs it makes it easy for him to grab it and run so very functional. He doesn't always like to share. The glow in the dark ability I would rate that good at all. The rest of the ball is good quality and holds up well against my aggressive chewer. Its easy to throw or kick. It isn't super hard but is holds it shape well. My dog is about 8 months old and is a mini goldendoodle. I think he was about 18lbs in the video. Perfect size for him. I would definitely recommend, I think your dog would love it!
