How can I adapt this cable to an HDMI cable?

Recently my laptop broke down, whereupon I bought a new PC. Now I've removed the screen from my old laptop and now I want to use it as a second screen. But I have no idea how I could connect the cable (so make HDMI). Does anyone have an idea or can I just solder it to an HDMI cable?

All cables are connected

You have only removed the display, that is not connectable.

There's more than one display in a monitor. This "more" of electronics makes e.g. From a Hdmi signal the impulses that the display understands.

This explanation is for laymen.

That does not work like this. You need a control mainboard which converts the signals.

In your case, this was installed in the motherboard (otherwise this "motherboard" is in the monitor).

Your TFT is for the ton or you can sell it. It is just a pane of glass with a little electronics without further function.

The monitor is not controlled via an HDMI signal.

Furthermore, you need a power supply.

Maybe such a set will help you: https://www.pollin.de/p/7-17-78-cm-display-set-mit-touchscreen-hdmi-vga-video-810841

The problem is that my screen has a different connection
