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 Mixer At A Great Price.
Color: Black, Size: normal
I purchased this mixer over 6 months ago. I use it at least 2 to 3 times a day to mix fiber into a flavored drink. It also gets used for mixing gravy and Chinese sauces. So from light to medium duty and no problems at all. One battery lasted over 4 months. I did try an alternate wand mixer($15 to $20) with variable speed to try and slow the mixing down a bit. It's low speed(fast) was the same as this mixer so I sent it back and kept this one. In addition to being more economical the simplicity of the single speed should give it good reliability. Lastly, if it gets damaged you're only out ~$7.00

Easy and it works
Color: Silver, Size: Compact
It works! It doesn’t have different speed settings, and you have to make sure you have the right kind of milk, but so far it’s been great and easy to use.

Simple upgrade that actually feels worth it
Color: Black, Size: normal
I replaced a cheap milk frother I had from Walmart with this one, and it’s definitely an upgrade. Right out of the box it just feels a bit nicer and more solid, not flimsy like the other one. It’s also noticeably more powerful. It froths milk really quickly and does what it’s supposed to without any effort. I did notice it only has one ring on the whisk compared to the two on my old one, but I honestly don’t notice any difference in how it works. Only small thing was getting the batteries in, which was a little tighter than I expected. Not a big deal, just took a second. Overall, it just works well and feels worth the price. I’ve only had it for a short time, but so far I’m happy with it and hoping it holds up.

Great frother at a good price
Color: Black, Size: normal
Works really well and priced appropriately. Produces rich froth with minimal effort and works MUCH better than other much higher priced frothers. Highly recommended. I hope it lasts a good long time.
