I used to be able to connect my Inspiron N5110 to my 40-inch TV using the HDMI port, but it has not worked for several months. In that time, I have tried: - purchasing a different HDMI cable

After several troubleshooting attempts when the issue is not fixed then we attempt to check the system details using the System Service Tag Number. As the System Service Tag Number is confidential information, it is requested by the Dell Employees in a private message.
