Many laptop models available in the market nowadays come with extraordinary features. Such features include wireless connectivity, HD display, and a clear image display, among other interactive capabilities. You might have come across specific projectors that are capable of presenting in quadrants. A different message is usually displayed on each quadrant.
Most projectors are portable and can be connected to a laptop. Various laptop versions are modified with either HDMI or VGA ports. These ports allow one to connect the projector to his/her computer using a VGA cable. However, your laptop may lack these ports; hence you need to acquire a VGA adapter to complete the connection.
Connecting a VGA projector to an HDMI port
Video Graphic Arrays have been long in use in most projection experiences. Due to technological advancements, the VGAs are gradually being replaced by different digital connection methods, including HDMI. The new advances have resulted in the thickness reduction of devices such as laptops and television sets. They offer better signal transfer between various gadgets, hence gradually being adopted by many manufacturers.
There are several circumstances that one will have to connect a VGA projector to an HDMI port to run a presentation. Thus, VGA connection is still applicable in most devices. Some VGA-compatible televisions and various video display units use a VGA interface when connecting to laptops. One can thus watch streamed events or videos from a projection done by a VGA interface connection.
Ways of connecting a VGA projector to an HDMI port
To attach a VGA projector to an HDMI port, there are several ways that one can go by for a successful connection;
a) Use of an HDMI to VGA adapter
This is a cheaply available accessory that allows one to send signals from your laptop to a VGA interface-enabled projector. However, it can have some limitations. Before attempting to make the connection, always ensure that your computer is off. The next step is to connect the video cable from your device, which for this case will be a laptop or a computer, to the projector.
Ensure you fix the cable to the external video port of your computer. Get your adapter. It is helpful because it is compact and provides a clear resolution (up to 1080p), hence creating a link for a VGA HD display. An advantage of the VGA adapter is that it is operational even without an external power supply.
It is important to note that you can connect one end of your cable to the system jack if the VGA and HDMI cables lack a connection to the system. Pug in the projector’s cable to a power source and turn it on. After your computer or desktop has loaded, please turn it on. To the audio port in the computer, connect a cable to the projector or any other sound system. This allows your presentation to be audible.
On following these steps, your presentation should start. An image should project to the bright surface. If you are using a desktop computer, you might need to upgrade the video card on your computer if it has a VGA connection.
b) Use of an HDMI to VGA converter
An HDMI to VGA converter is different from the HDMI adapter in that the converter can send both video and audio signals to the projector. Converters are also referred to as ‘Scaler.’ It usually has an attached USB or audio cable, allowing audio signals to be sent to the projector or a monitor.
The HDMI to VGA converters are generally more costly than adapters but are affordable in the market today. If your converter lacks a DC jack, you can use the attached USB as an alternative to power them.
HDMI to VGA converter and Adapter limitations
Having these connection methods allows one to send audio and video signals between the laptop and the projector. However, these accessories are limited to some capabilities, as explained below;
- The original quality of the video is lost when one opts to use a substandard cable. One should thus consult or ask for guidance on the type of cable to purchase for their connection.
- Both the adapter and converter do not support video resolution conversion in that they can only allow HDMI and VGA interface video format conversions. VGA resolution can go up to 800 * 600 pixels. HDMI, on the other hand, supports a resolution of up to 3820 * 2160 pixels.
If video signals sent to a VGA input originate from an HDMI source, there are more chances that the quality of the video is scaled down. The rate is lowered to the VGA’s maximum resolution.
VGA to HDMI conversion does not improve the resolution or quality of the original output signal but instead lowers its quality.
However, these accessories are the most convenient in projecting certain information to a more prominent display that supports the VGA interface as input.
Frequently asked questions on projectors:
- Can a projector be used for watching everyday TV programs?
The answer to this question is as simple as yes. Projectors can be used for everyday TV watching from our homes. Projectors can offer a large screen projection of even more than 100 inches at their price point. Their display as well does not affect your eyes.
Acquiring a projector will thus be cost-effective for a case of an extensive display experience. This is in that one will purchase the projector under the price of a lesser inch TV. Large TV sets are very expensive. Instead, one can opt to buy a projector for a more extensive and better-watching experience.
As of late, video technology is gradually shifting from the analog technological era for digital inventions, including Display port and DVI. VGA interface is rarely being used. However, many are cases where one will be needed to use this connection format. As discussed, one can use an adapter or An HDMI to VGA converter for his or her connection.
In summary, acquiring an HDMI to VGA converter will allow your device to send both audio and video signals. The adapter will only send video signals. The two connections are readily available in the market. One can choose which of the two to purchase to run their connection. Ensure you have a clear guide on the method you will need for your connection.
