Linux distro with KVM switch support
Which distro fully supports KVM switch?
FYI: I am switching between a Windows 10 desktop computer (referred as HOST 1) and a laptop rocking Ubuntu MATE 18.04 LTS (referred as HOST 2)- with IOGear GCS1642 ( http://a.co/iDhJKbT ) KVMP switch. The keyboard, mouse and other peripherals are working just fine for both hosts.
The desktop has 2 DVI ports, whereas the laptop has one VGA and one HDMI port, so I am using the respective converters/adapters, as my KVM switch only supports DVI.

I wouldn't expect the distro to matter. I've seen problems when booting a 'puter (various Linux and Windows) connected to a KVM when the 'puter being booted didn't have "focus," but 'twer fixed by rebooting with focus.
I'm currently running Windows 10, CentOS 7.5/Cinnamon, CentOS 5.11/KDE (x2) on my KVM with no problems.
Are you running a GUI? Which desktop? Suggest you concentrate on configuring the display while it has focus on the KVM...I doubt it's a KVM issue (given that the connections are all solid...try switching the video cable, maybe?)

KVM switches operate on a hardware level, not a software level. The OS doesn't even know they are there.

Well, that's what I used to believe, but now after some research, I am starting to develop my doubts.

I did some tinkering and I was able to at least duplicate my screen. The other host computer is running Windows 10 Enterprise without any problem.

'twer == it were
Does the computer work as you want when connected directly...that is, not through the KVM?
If so, it should work through the KVM (or contact IOGear support if not).

It does. My laptop has one VGA and one HDMI port. The switch has DVI cables. I tried a working VGA male to DVI female converter to connect, but that did not work. The monitor wasn't detected.
Now ... The cables coming out of KVM, go to a USB port replicator hub ( Sony VGP-UPR1). This HUB has one DVI & one VGA input. One of the DVI cables connects to this switch directly, whereas A single USB cable connects to my laptop. It does detect one of my 2 screens with 1920x1200, but the maximum resolution I am seeing in the display settings is 1024x768.
Attached is a diagrammatic representation of my current setup ( direct link).
