4. Listen for the Beep Sound from the Monitor
Another thing you can do is to keep listening to the beep sound from the monitor after turning it on because a beep sound might indicate that the monitor is turned on but has some issues with the screen or HDMI connectivity. In case, the LED indicator appears and then disappears again that means the power connectivity becomes loose enough.
5. Check for the HDMI Cable Connection
You should try checking out the HDMI cable connectivity with your PC and the Samsung Odyssey monitor because the physical connection can trigger multiple issues. You can also try using another HDMI cable to cross-check the issue.
Try using the correct display input to the computer as well as the monitor to ensure there is no issue with the input. Sometimes loose connectivity can also trigger monitor not turning on issues.
