JETCORE boots, but my monitor shows no display. Do I need a specific type of monitor?
If you have no display on an HDMI-only monitor, try a monitor that also has a DisplayPort or VGA input, while continuing to connect through HDMI. Those monitor types worked in the reported JETCORE setups, whereas the HDMI-only monitors tested in those cases did not. This is the first compatibility check to try for this symptom.
Connect the display before powering on JETCORE, select the monitor’s HDMI input manually, and use a known-working HDMI cable with the correct board-side connector
If the screen is still blank, check whether the Jetson is reachable over Ethernet or serial. If it is, the issue can be investigated as a display problem rather than assuming the board failed to boot. Share the monitor model, cable or adapter details, Jetson model, JetPack, and whether another display works. Those details help distinguish monitor compatibility from a cable or software issue.
