How can I troubleshoot the connection between my Samsung Odyssey G3 monitor and my GPU using HDMI and Display Port cables?

I have a Samsung Odyssey G3 monitor that I purchased in January, along with a second-hand PC from a friend. I was able to set up the PC and fix some issues, but I cannot get the monitor to display anything from the GPU. I have tried both HDMI and Display Port cables, but the monitor keeps showing messages that they are not connected. What steps can I take to resolve this problem?


If you have a Samsung Odyssey G3 monitor and a second-hand PC, you might encounter some issues with the connection between them. This article will guide you through some steps to troubleshoot the problem and get your monitor to display the output from your GPU.

Step 1: Check the power supply and the cables

The first thing you should do is to make sure that both your monitor and your PC are properly plugged in and turned on. Also, check the HDMI and Display Port cables for any damage or loose connections. Try to use different cables or ports if possible, and see if the problem persists.

Step 2: Check the monitor settings and the input source

The next thing you should do is to check the settings of your monitor and make sure that it is configured correctly. You can access the monitor settings by pressing the JOG button at the back of the monitor. Navigate to the System menu and select Input Source. You should see two options: HDMI and Display Port. Choose the one that matches the cable you are using to connect to your PC.

Step 3: Check the PC settings and the GPU drivers

The final thing you should do is to check the settings of your PC and make sure that your GPU is recognized and working properly. You can do this by opening the Device Manager on your PC and looking for the Display adapters section. You should see your GPU listed there. If not, you might need to install or update the drivers for your GPU. You can find the drivers on the official website of your GPU manufacturer, such as NVIDIA or AMD.

If you have followed these steps and still cannot get your monitor to display anything from your GPU, you might have a hardware issue that requires professional assistance. You can contact the customer support of Samsung or your PC vendor for further help.
