How to Connect Projector to Laptop without VGA Port

VGA port might seem like an outdated port, but it still serves as a practical option for many projectors. There are various institutions that still use projectors that run on VGA ports, and that too without compromising on the quality.  However, you might get into situations where you will have to connect a projector to a laptop that doesn’t come with a VGA port, especially Apple laptops.

Most modern laptops don’t include a VGA port as it is old and bites a decent amount of space in the body. If you get into a situation while providing a classroom or office where you have to utilize an old projector having a VGA, what would you do? How to connect a projector to a laptop without a VGA adapter? Well, it might seem tricky, but an HDMI to VGA adapter or converter can solve the issue.

You might think that a user should have a laptop with a VGA port in those situations, but what if the user doesn’t have one? The adapter serves as a great tool that you can use to provide presentation without having a VGA port laptop.

HDMI to VGA Adapter

HDMI to VGA adapter is a highly useful device that assists users with no VGA port on a laptop and wants to connect it to a VGA port-based device. HDMI is a digital signal, while VGA is based on analog signals. In HDMI, the data is transferred in the binary format, whereas in VGA, the information goes in the form of waves through electric pulses.

The main job of the adapter is to convert those digital signals carrying information in binary form and convert them into analog signals so that the projector can project the visuals. However, you should remember that these signals are not multi-directional, and they can only convert incoming video information coming from one direction. So you should avoid going for projector VGA to HDMI adapters as they won’t get the job done.

These adapters come in various price ranges, and they are readily available in the market so that you won’t have a problem owning them. However, you should always go for high-quality adapters as they ensure smooth transfer without any loss and that too with high bandwidth.

HDMI to VGA Converter

Like HDMI to VGA adapters, the converter counterpart also does the same job and also offers conversion in one direction. The conversion of video signals in these converters is also the same. However, what makes them different from adapters is that they also send audio signals along with the video signal.

When you want to use a laptop without a VGA port, an HDMI to VGA converter will help you to connect your laptop to the projector.  However, you should remember since these converters are not bidirectional so you should avoid using VGA to HDMI. Most of the time, these converters get an additional DC or USB jack for powering the converter. However, if your converter lacks a power jack, then you have to power them using a separate USB cable separately.

The bandwidth and signal loss percentage is essential for this converter type, and it is recommended to get good quality models. Like adapters, they also come with different price ranges, but cheap models tend to face a lot of signal loss and also have low bandwidth. If you are eyeing for professional-level conversion, then you might have to shell out more than $100 to own them.

Now, without beating around the bush, let’s start with how you can projector a laptop without a VGA port.

How to Connect Projector to Laptop without VGA

Here we will discuss how you can connect a projector having VGA port to a laptop with no VGA cable;

  • To begin with the process, it would be safe to turn off both the projector and laptop before hooking the cables.
  • Now take one HDMI cable and connect its one end to the external port, which is primarily located on the left side. In a similar way, take one VGA cable and hook it to the intended port in the projector. Remember, while connecting the VGA cable, you should adequately tighten the screw or else you won’t get any visual.
  • Since you don’t have a VGA port on the laptop, you can use an HDMI to VGA converter for a smooth connection. You just have to hook one end of the HDMI cable from your laptop to the HDMI port and the other end of the VGA cable to the converter. You will get a smooth video quality around full HD without any fuss (depends upon the converter quality). Most importantly, you won’t be needing any external audio input from your laptop to transmit the audio. The converter comes with an inbuilt audio transmission, but you will have to power the converter separately.
  • For HDMI to VGA adapters, the connection process is similar where you have to put the HDMI cable to the HDMI side and VGA cable to the VGA side. But the problem with the adapter is that they will only transmit video from your laptop to the projector. To get audio while playing content in the projector, you will have to use a separate audio cable like an aux cable. However, like a converter, you won’t have to power the adapter to use it.
  • Once you have connected the cable, now you will have to turn on the projector and check whether the projector is connected. If you face any flickering or black screen after playing any content, then you should check the connection. A loose cable can often lead to a blacked-out screen.

Problem Associated With HDMI to VGA Conversion

As we all know, VGA is outdated technology and a projector using this port as the primary option is limited to a specific resolution. The main problem is that you can’t opt for high-resolution projection with a projector port having VGA. Whether you go for an adapter or converter, they will transfer the video information, but they won’t be able to support the incoming resolution. VGA is only limited to 800 X 600p, while HDMI can transfer resolution up to 3820 X 2160p so that you won’t get the incoming quality on the big screen.

Similarly, the audio quality isn’t that great that you might get with an HDMI cable. Another problem with converters and adapters is that low-end models tend to ruin the quality by a large margin. You will find a loss of quality in visuals when your project any presentation or video on the big screen. Check out our detailed guide on how to transfer sound from laptop to projector.


When dealing with an old projector, the query of “how to connect the laptop to a projector without VGA port” often arises. Through our article, we have provided you with all the detailed steps that will assist you in establishing a connection with your new HDMI laptop to an old projector with VGA. You can’t simply use a VGA cable for projector to a laptop as you will need an adapter or converter for support.

Importantly, getting an adapter or converter won’t be expensive, and they are readily available at an affordable rate. However, it would be best to opt for high-quality converters as they don’t compromise on transmission.
