To connect your Samsung monitor to a PC with HDMI, plug one end of a high-speed HDMI cable into your PC's HDMI output port and the other end into the monitor's HDMI input port. For optimal performance with higher resolutions and refresh rates, use a high-quality, high-speed HDMI cable that matches the capabilities of both your devices.
Select the correct input source on your Samsung monitor
After making the physical connection, the most common cause of a "No Signal" error is that the monitor is not set to the correct input. To fix this, locate the "Source" or "Input" button on your Samsung monitor, typically on the side or bottom edge. Press it to cycle through the input options until you select the correct HDMI port your PC is connected to. For example, if your cable is plugged into the HDMI 1 port, you may need to switch from HDMI 1 to HDMI 2 if the monitor is currently set to a different input. Alternatively, access the monitor's menu by pressing the "Menu" button, navigate to "Input Source" or "Connected Devices," and then select the corresponding HDMI input. This same input-switching process applies when you later connect PS4 to PC monitor with HDMI, making it easy to share the display between devices.
Adjust display settings in Windows or macOS
Once the monitor is detected, configure the display settings to get the best image. On a Windows PC, right-click on the desktop and select "Display settings" to adjust the display resolution, refresh rate, and orientation. You can also choose how your screens work together, such as extending or mirroring the desktop. On a Mac, navigate to "System Preferences," then "Displays," and select "Detect Displays" to configure the monitor settings. If the monitor does not appear, use the "Detect Displays" function to force the operating system to find it.
Troubleshooting tips and optimal settings
If you encounter a "No Signal" error, first ensure the HDMI cable is firmly seated at both ends. Try a different HDMI cable to rule out a faulty cable. Also, confirm the correct input source is selected on the monitor as described above. For an enhanced gaming experience, enable "Game Mode" on your Samsung monitor through its quick settings or menu to optimize the display. If you find that some monitor settings, such as refresh rate, appear grayed out in the monitor's menu, this is normal because those settings are controlled by your PC when connected via HDMI. You can adjust the refresh rate in your PC's display settings instead. If you notice image degradation or contrast issues, use the "HDMI Black Level" function found in the monitor's On-Screen Display (OSD) to correct it. If your laptop lacks an HDMI port, you can still connect HDMI laptop to DisplayPort monitor with a simple adapter. Monitors generally do not require manual driver installation, as modern operating systems automatically manage this process, so you can expect the connection to work without additional software.
