Simple queries about dual monitor KVM configuration
Simple queries about dual monitor KVM configuration
Hello,
I’m trying to purchase a KVM switch for my home office where I plan to install new dual monitors. I have an Ubuntu desktop and a Windows laptop that I want to connect via the KVM. There’s no need for password protection on any of the devices. All these machines will be within five feet of each other, and also close to the keyboard, mouse, and monitors. Both the keyboard and mouse use USB-A connectors. I don’t require remote access to any of them.
After reviewing many resources on KVM switches, I have a few questions I’d like your advice on:
- My desktop has one HDMI port and one VGA port. Should I use an HDMI cable between the desktop and the KVM switch, or can I connect a VGA cable from the desktop to the KVM and then route HDMI from the KVM to the monitors? Do I need two identical ports on the video card at the desktop to support two monitors, or is it possible to connect just one port on the video card to the KVM and use it for splitting to the monitors?
- The Windows laptop has a single HDMI port. Is it possible to use one HDMI cable from that laptop to the KVM switch so both monitors, keyboard, and mouse can be used simultaneously?
- USB mice and keyboards can connect via their own cables, but could I have the KVM switch connect to the computer using just one USB cable so that both devices work together?
- Would you recommend any specific KVM switches that fit this configuration?
Thank you very much for your help. I really appreciate it!
Best regards,
Jake
The cables used to the KVM switch vary based on its connections, and you might need adapters for your video card. Some models support both HDMI and VGA. KVM switches connect one-to-one, meaning they only link to a single monitor if you have just one video output. It seems you may require an HDMI to VGA converter if you want to use it with a dual HDMI KVM setup. Consider checking the options listed for compatibility.
Thank you for your reply. The need for a VGI to HDMI converter depends on how you want the desktop to display on multiple monitors. If you use an HDMI dual KVM, it’s not strictly necessary for the laptop to have two outputs, but it can help manage connections. Regarding USB devices, they can connect via separate cables, and the KVM switch can link to I/O ports on each computer with a single USB cable, allowing both mouse and keyboard to function properly.
The KVM switch includes HDMI ports, meaning using two monitors requires matching the connection type used by the switch, which is HDMI. If only an HDMI port exists, a converter is necessary for the other port. For the laptop, dual displays are possible only if video outputs are separated from it to the KVM, or a single screen suffices. The mouse and keyboard connector is the core feature of the KVM, allowing all devices to connect through one set to the switch, directing connections to the computers as needed.
