I bought a 10 meter HDMI cable of average quality to connect my laptop (HP probook 4530s - windows 10 pro) to my LG digital TV. But although Windows and TV detect the connection via cable, it seems both cannot use the signal.
Further investigation led to these:
- Connecting the same TV via the same cable to a satellite receiver: OK; (so cable is fine)
- Connecting the laptop to the TV via 1.5 meter HDMI cable: OK; (so there's no problem for laptop to send signal)
So what is the problem here? Is it the case that laptop outputs a weaker signal compared to say satellite receiver on HDMI port?
