How can I hook up two computers to one monitor effectively?

I’m trying to run my home office setup more efficiently by using one monitor for two different computers. The idea is to avoid the clutter and expense of having two separate monitors. I’m not sure what kind of hardware or cables I need, and whether both computers can be connected simultaneously without constantly swapping cords. I’m also concerned about how to switch between the two computers easily and whether there’s any loss of display quality or response time. Understanding these challenges and having a clear plan before I start could really make a difference.

For those who prefer a more tech-savvy solution, here’s an interesting alternative using DisplayPort for daisy chaining:

  1. Check compatibility: Verify your monitor and both computers support DisplayPort multi-stream transport (MST).
  2. Connect with Daisy Chaining:
  3. Connect the first computer to the DisplayPort input of the monitor.
  4. Use a second DisplayPort cable to connect the DisplayPort output of the monitor to the second computer’s input.

This way, I could switch inputs via my monitor’s interface, and the quality remained intact with minimal lag.

A costlier but more integrated solution would be using docking stations:

  1. Docking Stations: Buy two docking stations, one for each computer.
  2. Connect Docking Stations:
  3. Attach each docking station to a computer.
  4. Use the respective outputs from each docking station to connect to the same monitor.

What I like about this setup is that it also helps manage other peripherals like keyboards and mice through the docking stations.

I tackled this by using a simple HDMI switch with multiple inputs. Here’s what worked for me:

  1. Get an HDMI switch: Purchase an HDMI switch with at least two inputs and one output.
  2. Connect computers and monitor:
  3. Plug each computer into the HDMI switch’s input ports.
  4. Connect the HDMI switch’s output to your monitor.
  5. Use the switch: Manually switch between inputs using the buttons on the HDMI switch.

This method is cost-effective and easy to connect, though it might not support higher resolutions if the HDMI switch is outdated.

When I faced the same issue, I opted for a method that only involved software solutions and my existing setup:

  1. Remote Desktop Software: I installed remote desktop software on both computers (such as TeamViewer or Chrome Remote Desktop).
  2. Single Monitor Setup: Place the two computers side-by-side and use the software to view and control the secondary computer from the primary one.

While this requires both computers to be on the same network, it’s handy because it means I didn’t need to purchase any new equipment.

Using a dual-input monitor can solve your problem. Monitors with multiple video inputs, like HDMI and DisplayPort, let you hook up two computers without additional hardware. Here’s what you need to do:

  1. Check your monitor’s inputs: Confirm your monitor has at least two video inputs.
  2. Connect your computers:
  3. Use an HDMI cable to connect one computer to the HDMI port.
  4. Use a DisplayPort or second HDMI cable for the other computer.
  5. Switch inputs: Use the monitor’s built-in menu to switch between inputs. This method only takes a few seconds.

I appreciate this approach because it doesn’t require purchasing extra hardware, and it’s straightforward to set up.

To hook up two computers to one monitor, a KVM switch is what you need. Here’s how I did it:

  1. Purchase a KVM switch: I bought a reliable KVM switch that supports video inputs and USB connections because I wanted to control both computers with one keyboard and mouse.
  2. Connect the KVM switch:
  3. Plug both computers into the KVM switch using HDMI cables (or whatever video output your computers use).
  4. Connect your monitor to the KVM switch as well.
  5. Switch control: The KVM switch I selected has a physical button to switch between computers. Some devices offer hotkey switching, which you might find more convenient.

This setup helped me reduce clutter and easily switch between two computers without any noticeable degradation in display quality.

One creative approach I used involves using additional software alongside hardware solutions:

  1. Extend Your Display:
  2. Check if your monitor supports multiple display inputs.
  3. Connect each computer to a different display input on the monitor.
  4. Software Solution:
  5. Install software such as Synergy that lets you use a single keyboard and mouse seamlessly across both systems by sharing one set of peripherals over a network.

This method gave me more control and flexibility in managing both computers without switching hardware manually.
