how to install SmartAVI 4-Port HDMI, USB and Audio KVM Switch

Installing the SmartAVI KVM switch is a straightforward process intended to minimize downtime and maximize productivity. Follow these steps to get your multi-computer workspace up and running quickly, with stable video, input, and audio sharing across all connected devices.

  • Power down all computers and the monitor before making connections to prevent any short-circuit or signal issues during setup.
  • Connect each computer’s HDMI output to the corresponding HDMI input on the KVM switch. Then connect the KVM switch’s HDMI output to your monitor or display using a standard HDMI cable.
  • Plug your USB keyboard and USB mouse into the USB ports on the KVM switch to enable shared control across all connected computers. If your setup includes additional USB peripherals, connect them to available USB ports on the switch as well.
  • Route the audio signals by connecting each computer’s audio output to the KVM switch’s audio inputs, and then connect your speakers or headphones to the switch’s audio output. This ensures synchronized audio when you switch between hosts.
  • Appoint the active computer by pressing the front-panel tactile switch or by enabling auto-scan mode. Power on all devices, then verify video, keyboard, mouse, and audio are correctly routed for each machine as you cycle through sources.
  • Fine-tune your setup as needed. If you’re using a high-refresh-rate monitor or multi-monitor array, confirm the HDMI handshake remains stable and that audio output remains synchronized with the video as you switch between computers.

Great Chair! Worth the Price!
Color: Sky Blue, Size: Pack of 1
LOVE my new desk chair! I got the Sky Blue which is a really pretty blue in person. I work from home in tech, and had been getting constant headaches no matter what position I was in. I finally decided to invest in a better desk chair, and I'm SO glad I did! It's much more supportive and comfortable. I really like that I can flip the arms up or down, and the height is easy to adjust. Also, because I can flip the arms up, I can keep the chair out of the way when I'm not working by putting it right up against the desk. Very much worth the price! Assembly was simply and quick. Not even 30 minutes. Also, when I had a question about the chair, their support team was quick to respond and very helpful. Highly recommend!

Great quality chair, regardless of price.
Color: Black+white, Size: Pack of 1, Color: Black+white, Size: Pack of 1
Great quality chair, regardless of the price, period. So well packaged that it took almost as long to unwrap as assemble. Assembly was easy (loved the Allen wrench with sturdy handle). I am 6'2" and the fit and height adjustments work well for my height. Comfort is personal, so I like the semi-firmness of the seat. While the chair is constructed of heavy gauge plastic the base is solid metal with enamel finish: I love the look. The arm rests line up perfectly to my computer keyboard. I expect many, many years of service.
