HDMI port split?

I would like to know the following: if I have a laptop with an HDMI port and would like to know whether there are any adapters that I want to connect, for example, 5 more screens (my exaggerated wish) and would like to use the Extend screen function and so all 6 screens are perfect want to use and now I want to know if there are adapters that can.

Yes, of course, but then every monitor shows the same thing

So you can't expand? Are there GraKas that can do this (i.e. Have so many ports)

Modern GPUs usually have at least 4 ports

Ok thanks for the quick and helpful answer 👌

Simply does not work with HDMI. Does the notebook have other display connections?

Several monitors controlled separately on one connection is only possible via the display port, some notebooks have that, some of them implemented via USB-C with DP.

The only thing I could imagine would be if a 4k picture was broken down into 4 full HD pictures (quarters), that you would then arrange 4 full hd monitors so that a 4k picture would come out again.

I know something from the professional field in the area of video tapes or large screen led walls…

this of course assumes that the hdmi port of your device outputs 4k.
