So, let’s consider connecting a projector to an AV receiver. To connect a projector to an AV receiver, you need the following:
- A projector
- An AV receiver with the projecting capability
- Projector cable (VGA cable or HDMI cable)
- Audio cable
- Video cable
- Turn ON your AV receiver and projector
First, connect the projector to the AV receiver using a cable (e.g., HDMI cable, VGA cable, or an audio cable).
Then connect the AV receiver to the power supply and turn it ON. Next, turn ON your projector and press the “Source” button on your remote control and select the “AV Receiver” option where you have connected the cable. Using a VGA cable, use your remote controller to set the source to “Computer 1”. If you are using an HDMI cable, use your remote control to set the source to “HDMI 1”.
When you have completed all these connections, project what is seen on your computer screen.
It does not matter which projector input is selected as long as it corresponds with the connection used. It is unnecessary to switch between the AV receiver and TV/Monitor inputs on your TV/Monitor as this can be done via remote control of your projection device instead.
Why do people use a projector?
A projector provides a big-screen experience on a wall or a table. A projector will turn any image into a huge 100-inch display. It means that everyone can enjoy movies in their own homes like in the cinema. You can also connect your laptop, smartphone, or tablet to the projector and watch movies from it on the projection screen. Projectors are also helpful for playing games on a big screen.
Projectors are handy tools for projecting an image onto a bigger surface than the source. For instance, if you have a PowerPoint presentation that you want to show, projecting it with a projector will be far more effective than just showing it on your laptop’s screen.
A projector is recommended to use in darker environments or where the image is viewed from a distance.
How to choose a good projector for a home cinema?
When choosing a projector for a home cinema, you have to pay attention to your budget and think about what is more essential for you: image quality or size of the projected image. Assuming that there is quite a lot of space in your room, the most important parameter is the maximal resolution which allows you to project a big-sized picture from even close distance. There are two types of resolution in projectors: horizontal and vertical. The horizontal resolution is the number of visible lines on an outstretched image (for example, when you’re standing several meters away from the screen). Vertical resolution is the number of pixels displayed on each line.
Another important parameter when choosing a projector is light output or brightness. This parameter is responsible for the quality of the projected picture in a darker environment. Another, less important parameter is contrast ratio – the difference between the brightest and darkest colors that a projector can display at one time.
If you need a projector for home cinema use which will be used mainly in daylight or a bright room, there’s no need to buy an expensive model with effective resolution.
