If your laptop and projector both have VGA ports, you can connect them with a VGA cable and no adapter.

VGA: This is an older video connector that is limited to a resolution of 640x480.

Some projectors do support USB-C video input, though, in which case you can connect your laptop directly to the projector via a USB-C cable.

USB-C: If your laptop uses USB-C to output video, you’ll typically need to buy a dock that includes an HDMI port or a USB-C to HDMI adapter.

If it does, then you can either use an HDMI-to-DisplayPort cable or an HDMI-to-DisplayPort adapter.

DisplayPort: These are more commonly on desktop video cards, but your laptop may have one.

You can use a cable with HDMI on one end and HDMI type-c on the other or an adapter.

Mini HDMI Port: Also known as HDMI type-c, these are functionally identical to HDMI, just much smaller.

HDMI is the easiest way to connect a projector to your laptop. HDMI Port: If your laptop has a full-sized HDMI port and your projector has the same type of port, you won’t need an adapter.
