Thanks for posting your question on Justanswer.com, a global paid independent support site.My Name is ***** ***** I will be assisting you today. Can you tell me, if your laptop is able to detect the TV or not ?
Can you tell me, which version of Windows is installed in your PC ?
OK, did you selected the correct input source in TV ?
Did you restarted the laptop after connecting the cable ?
Please open the link below and follow the steps then, let me know how it goes for you.
Then, it seems either the cable or the port on the laptop is defective. The cable can be defective because this type of cables is very cheap and low quality. You can replace the cable and check once more. As there is no other way to connect the laptop with the TV. One more thing, you can check your TV, if there is any VGA port present on it or not ?
No! do not try that, because the VGA port and the HDMI ports on both the laptop are output port.
OK, it is confirmed that the VGA port is working. Then, it can be the cable which is defective.
Then, it means the video card on your laptop do not support digital signal output, you will need two more things to complete the connection, please watch the video from the link below to have some idea about how to connect a nondigital VGA port to HDMI.
Yes, as it is very difficult to know if the card support digital signal or not and I do not want you to spend too much money on the converter and other cables, but now as the cable is not working it is confirmed that the video card do not support digital signal.
If the laptop is too old then, there is no need to spend any more money on the other cable or converter.
