The other solution is adding a graphics card to your laptop externally.
How can you add an external graphics card to your laptop?

This way, you can add an external monitor to your laptop’s built-in screen. You are not limited to two screens with this external graphic card. It allows you to gain an external graphic output. Using this external graphics card, you can connect your USB A laptop to your VGA monitor i.e., your desktop PC using this external graphics card.
So basically, this is a portable case for a graphics card?
Yes. It houses a separate graphics card that improves the graphics processing speed of an ultraportable laptop when it is connected. Usually for games and CAD programs that need a lot of graphics. You can use any third-party graphics card with the core, which makes it somewhat future-proof because you can always upgrade by swapping in a new card. Plus, since it’s a Razer product, it works best with Razer laptops, but it can be used with any laptop that has a Thunderbolt 3 port.
This lets you connect your desktop’s graphics card to your laptop and gain a better GPU performance without replacing your upgrading your graphics card.
The connector does not cost much and helps you add an external video card. This is not for gaming purposes, however.
