Is it safe to leave an HDMI cable plugged in from GPU to TV while using a different monitor with the TV powered off?

[BroadSTBeast]

I have my GPU plugged into both a monitor at my desk and an OLED TV across the room which I alternate back and forth between depending on whether I'm working or playing a game. I'm wondering if there is any risk to keeping my GPU plugged into the TV even when I'm just using a monitor (and the TV is off). I normally wouldn't have thought twice about this but a few months ago I had an LG CX TV which died out of warranty due to a mainboard issue; while researching what could of caused this, I saw a Reddit post of someone who said that leaving the TV plugged into a GPU when not in use could wear out the mainboard. I'm not sure if there is any validity to what that post said but it's made me a little afraid to keep my GPU plugged into my new TV all the time to where I unplug the HDMI cable every time I'm just using the monitor. 

 

I'm wondering if it's okay to just leave the HDMI cord plugged in all the time or if anyone has some insight to whether this setup can cause issues with OLED TV's. Any help on this would be greatly appreciated!

Nope, there isn't. You just have to be mindful if Windows is outputting to the TV needlessly when it's off. 

 

That Redditor's logic doesn't make sense. So leaving an unused display plugged in will wear out the motherboard but actually utilizing that display out doesn't? Even if there is additional wear (which there certainly wouldn't be any), it'll be a negligible amount.

I don't really see how the motherboard of a turned off monitor would wear out from that.

 

If anything, I'd be worried about constantly plugging and unplugging the monitor to wear out the plug's contacts.

@Eigenvektor @BlueChinchillaEatingDorito Thanks for the advice guys. I'm gonna leave it plugged in and not worry about it.

You're more likely to break the connector from constantly unplugging, and plugging it back in, than you are to wear out any components on the motherboard while the display is off.

solved already but there is no issue with having more than 1 monitor plugged in and switching back and forth. i have my computer, a couple of gaming consoles and my TV box all plugged into my TV and i have had no issues at all for the past several years i have been using this used when i go it TV and i swap to different inputs all the time.
