    Will my hdmi wire be ok?


    I have a tv. I am connecting my laptop to hdmi 4 on the tv and I am connecting a tv channel receiver to hdmi 2 on the tv. I regularly switch between hdmi 2 and hdmi 4 on the tv. I am duplicating the laptop screen on the tv.

    Today I restarted the laptop while the tv was on hdmi 2. After that I switched the tv to hdmi 4. Normally when I switch the tv to hdmi 4 the laptop screen shows on the tv. This time it didn't happen and the tv stayed black. I unplugged the hdmi wire from the laptop and I plugged it back. The laptop screen showed on the tv.

    I wasn't sure why the tv stayed black when I switched the tv to hdmi 4. After that I thought that maybe restarting the laptop while the tv was on hdmi 2 could have messed up something. I restarted the laptop again while the tv was on hdmi 2 and then I switched the tv to hdmi 4. The same thing happened again and the tv was black. This time I closed the laptop lid so the laptop went to sleep and then I opened the laptop lid and the laptop woke up and then the laptop screen showed on the tv.

    In the end I figured it out. If I restart the laptop while the tv is on hdmi 2 then there is no active hdmi connection when windows starts so the laptop ignored the hdmi cable and that's why the tv stayed black when I switched to hdmi 4 and I have to restart the hdmi connection by either unplugging the wire and plugging it back on or putting the laptop to sleep and waking it up. Am I correct? Is that safe and it won't spoil the hdmi wire?

    Hello,

    Disconnecting and reconnecting the cable often risks damaging the female hdmi socket of the computer or the TV. Prefer to put the computer to sleep. And have you tried from the start menu to choose to disconnect from Windows and reconnect?

    You can, if it has not already been done, in the screen choice menu where there is duplicate-extend etc. select only the computer screen and then reselect duplicate.
