I have that model of TV connected from a computer to the HDMI 2.1 port (HDMI IN 4) of the TV and until yesterday it worked without problems, but I disconnected the cable, I reconnected it and it stopped recognizing the PC. The cable is also 2.1 although I do not have a graphics card with 2.1 output, so for all intents and purposes it works as a 2.0, even so it worked as 2.0 connected to the HDMI 2.1 port (HDMI IN 4) of the TV. Until yesterday. It is not a problem of the cable because connected to the other 3 HDMI ports of the TV (which are 2.0) it works without problems. I also tried another HDMI cable (this time a 2.0) and it works on all HDMI ports on the TV except HDMI 2.1 (HDMI IN 4).

Hi, as I said my graphics card does not have an HDMI 2.1 output, but until yesterday it worked fine (although working as 2.0) connected to the HDMI 2.1 port (HDMI IN 4) on the TV.

 

I want to make sure that the HDMI 2.1 port on the TV works well for when I decide to buy a graphics card with HDMI 2.1 output.
