Question: Which products do you recommend for a 4-port DVI KVM with audio to switch between Powermac G5, Mac Pro OS X 10.10.5/10.11.2 and Windows 7/10. Peripherals: 24" PA 248 Asus LCD screen, wired USB 2.0 Mac keyboard and mouse. This is for home use.
Answer: Thank you for your inquiry,

Based on your specifications, I would recommend one of the following switches:

Adder AV4PRO-DVI-US - DVI-I (Analog VGA, and digital)
SmartAVI dvn-4pros - DVI-D (digital only)
IOGEAR GCS1204G - Discount KVM - DVI-D (digital only)

All of the previous switches have switchable USB ports, audio, emulated display signal and USB for keyboard and mice (eliminates any lag for regular switching), support at least 1080P resolution, and support MAC and Windows.

There are a couple of other questions that I would ask that might change my recomendation. Please feel free to respond to this message if you have any of the following requirements.

1) How far away are the PCs from each other? How far away are the PCs from the user station where you will be working? - only if further than 15 ft
2) Do you have a minimum resolution you would like to achieve? (i.e. 4K, 2K, 1900 x 1200, etc.)
3) Do you have any more specific requirements such as switching via push buttons, form factor, touch screen support, RS232 control, etc?
4) Would you like to be able to access these computers over the web anywhere in the world via the KVM switch? (KVM Over IP i.e. AV3008)

Question: What is the basic different in the Kvm switches, where one is digital only and another one is Analog, VGA and digital.
Answer: Thank you for your inquiry,

Functionally the main difference for a KVM that supports digital signal is that you can plug in a DVI (DVI-D, DVI-I), a HDMI, or a DisplayPort cable into the KVM without an active converter (passive adapters may still be required). An Analog signal allows for VGA cables.

Signal wise, the main difference is that over longer distances an analog signal slowly degradates in quality, while a digital signal will be full quality until the distance gets too long and the signal fully cuts out. Analog typically allows for longer distances.

Question: What's the best option for a 4-port KVM switch for home use? I have one laptop with SVGA, one laptop with HDMI, a MacBook Pro with Mini DisplayPort and a desktop with DVI. My monitor supports SVGA, HDMI and DVI. I'm using wired Logitech mouse and wired Logitech keyboard. The Mac has a 3-way converter plug that supports SVGA, HDMI and DVI. I'm inclined to go for a switch that supports DVI-I, and presumably using plug converters for the SVGA and HDMI computers. I currently have a Belkin SOHO KVM (all SVGA), although there are problems with the mouse if the KVM is plugged into a USB 3 port on one of the computers. The computer with HDMI is a brand-new Lenovo ThinkPad T580, where all the USB ports are USB 3.1 (one which is Gen 2/Thunderbolt/DisplayPort)
Answer: Thank you for your inquiry,

For a KVM Switch for home that would support 4 devices with VGA, DVI, HDMI, & Mini-DP connectors, you could use one of the KVM switches below. I would recommend standardizing on HDMI or DVI with Video Converters for the other video connector support, or on CatX which often supports all of the above.
  • CyberView U-801 8-Port CatX KVM that supports VGA, DVI, HDMI, & DisplayPort through naitive KVM cables (note, no extra USB peripheral device hub in current form)
  • SmartAVI UHDN-4P 4-Port HDMI KVM Switch
  • Adder AV4PRO-DVI 4-Port DVI-I KVM Switch
Does the Logitech Mouse have any special functionality like macro keys, or something outside regular mouse functionality? USB type (2.0 vs 3.0 vs 3.1) should typically not affect mouse functionality, but most KVM switches emulate USB keyboard and mouse signals, which might affect special features outside the standard USB-HID specification.
