What is the best way to connect 2 computers to this monitor


If you have two separate computers for different purposes, such as personal and work use, you may find it convenient and necessary to connect both to a single monitor. Many monitors have dual inputs, making such a connection simple. However, you might need a keyboard, video and monitor switch to accomplish this task if the monitor lacks a second input. Dual Inputs
Step 1 Examine the back of your monitor for the presence of dual video inputs, such as a single VGA and DVI or HDMI output.
Step 2 Connect the VGA cable to one computer. Plug the other end of the cable to the matching input on the monitor. Rotate the retaining screws until tight at both ends of the cable.
Step 3 Plug the DVI or HDMI cable into the back of the second computer. Insert the other end into the monitor's digital video input. Screw down the retaining screws if you're using DVI.
Using a KVM Switch
Step 1 Ensure both computers are turned off. Place the KVM switch on your desk where it is within convenient reach.
Step 2 Locate the video output port on the back of the KVM switch. Plug a VGA cable into this port. Plug the other end of the VGA cable into the monitor.
Step 3 Plug the VGA monitor outputs from each computer into the inputs on the back of the KVM switch. Tighten the retaining screws down for each connected VGA cable on the computers and the KVM switch.
Step 4 Plug the keyboard and mouse cables into their respective outputs on the KVM switch. Plug each set of keyboard and mouse cables from their ports on each computer into the matching inputs on the KVM switch. Plug each cable in sequentially to avoid mixing them up between machines.
Step 5 Double-check that the mouse, keyboard and monitor cables leading from each computer all correspond to the right machine. Plug the KVM switch's power cord into a nearby AC outlet or power strip.
Step 6 Turn the computers and monitor on to verify the connections are correct.

Required Items

  • VGA cable
  • DVI or HDMI cable
  • KVM switch
  • Power strip (optional)

Hi bpollen,
you will use the computer for {GUI} Graphics User Interface!

If you are not receiving power from a known working wall outlet and if the power cord is removable, replace it with the one connected to the computer and attempt to power on the monitor again. If the monitor still does not get power or it is not removable, it is recommended that the monitor be replaced or serviced at a local TV / Computer repair shop.

If the light is orange or flashing ensure that the monitor is not in a suspend mode by moving the mouse or pressing a key on the keyboard.

Hardware Issue

If you have followed the above recommendations and are still encountering the same issue, it is likely that the computer may have either a bad video card or monitor. The best method of determining this is to do one or both of the following:

  • Disconnect your monitor and attempt to connect it to another computer. This can be a friend or family's computer and/or it can be taken to a service center.
  • Borrow a computer monitor and connect it to your computer. This will not harm the other computer monitor in any way.

If your monitor works on another computer it is safe to assume that the video card or potentially the motherboard within the computer is bad. Steps in troubleshooting a video card can be found on document CH001028.

Hyundai monitor connects two computers .how do i switch between them?


Use a KVM (keyboard,video, mouse) switch to connect your 2 computers to this monitor. Then you can also have only one keyboard and one mouse. Connecting to the VGA header with one computer and the digital with another is probably not a good idea and the only way that can work is if your monitor has a built in video switch that can be controlled with software. If that is the case they would boast about it in the user manual and tell you how to activate the switch. VGA KVM switches are relatively in-expensive. Some high end KVM switches will exceed the cost of your monitor.
