I heard that KVM switches use keyboard/mouse emulation for using the keyboard/mouse connected to it. I'm not sure if USB switches use emulation for using keyboard/mouse functions however. Do USB switches emulate keyboard/mouse for using keyboard/mouse connected to them or is it done directly? Would a KVM switch have more input lag than a USB switch? I right now have a 4-port HDMI switch but I'm not sure if it's better to buy a KVM switch and use the HDMI/USB signals from one box or keep using my HDMI switch and buy a USB switch and take up more desk space and one more power outlet. I'm using a wireless keyboard and wireless mouse via the unifying receiver and my keyboard does not have multidevice functionality but my mouse does. Sure I could buy a keyboard with multidevice functionality but that will limit me only to certain Logitech keyboards and I still wonder if it's just better to use a USB or KVM switch and do the switching via those boxes instead of using the device buttons on those kind of keyboards and mice to do the switching?

I use a a USB switch to switch my mouse and keyboard between my work setup and my gaming setup. I notice no additional latency or any issues with it. I have it held to the back of my desk with Velcro so I just reach over the edge to press the button to switch back and forth. I also didn't have to use supplemental power for it. Seems to run my devices just fine without it.

Here is the one I bought. https://smile.amazon.com/gp/product/B01N6GD9JO/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I was asking if KVM switches have more input latency than dedicated USB switches? That's the only thing holding me from purchasing a KVM switch and I rather have one box for USB and HDMI devices than two separate boxes, which are a USB switch and an HDMI switch as my monitor only has one DVI input.
