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.
