Do you need an adapter to connect a laptop to a projector?
Most projectors include an HDMI input port, so you probably won’t need an adapter if your laptop has a full-size HDMI port. The same is true if your projector has a VGA input and your computer includes a VGA port. Depending on the ports available on your laptop, you may or may not need an adapter. In other cases, you need an adapter.
The following are some common connectors for projector-made projectors. Here are the types of ports your laptop has and an explanation of the adapter if you need it:
The main reason for using HDMI is convenience. HDMI is the easiest way to connect a projector to your laptop. If your laptop has a full-size HDMI port and your projector has the same type of port, you won’t need an adapter. You can find this connection on a wide range of A / V and electronic devices, including projectors, laptops, and gaming consoles. The biggest advantage of HDMI when displaying the first view is that it reduces the number of cables you use. HDMI also has an advantage in terms of video quality.

If both your laptop and projector have VGA ports, you can connect them to a VGA cable and an adapter. Most modern video cards today do not have VGA, but they were available until the end of 2010. However, you also need to use an alternative method to transmit sound from your laptop to the projector, as VGA does not transmit HDMI audio signals.
The DVI connection is newer than VGA, and it provides a more intense image. It can be used with any projector but it is not used on TV. It is only available on desktop computers for use with monitors. As a result, projectors with DVI inputs can only use one desktop computer.
Display Port to Connect a Laptop to a Projector:
DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip makers and standardized by the Video Electronics Standards Association. The interface is primarily used as a computer source to connect a video source to a display device and can carry data in audio, USB, and other forms. The interface is backward compatible with other interfaces such as HDMI and DVI using active or passive adapters. These are more commonly used on desktop video cards but maybe on your laptop. If so, you can use an HDMI-to-DisplayPort port cable or an HDMI-to-display-port adapter.
Universal Serial Bus (USB) lets you connect a flash drive or external hard disk drive (HDD) to play movies. These can be connected or disconnected because the movie has been reheated to run. If your laptop uses USB-C to provide video output, you’ll usually need to buy a dock that includes an HDMI port or a USB-C to HDMI adapter. Some projectors support USB-C video input, although in this case, you can connect your laptop directly to the projector via USB-C cable. While all computers have USB, it is not used to connect to projectors or TVs without USB-C. This technology is very new and probably not available on projectors or TVs.
