The steps to help connect your Discovery Wonderwall Projector to a computer will be discussed in the next section of this article.

How to Connect Discovery Wonderwall Projector to Your Computer

As stated earlier, connecting your Discovery Wonderwall Projector to your computer can be challenging. This is because the projector comes with RCA inputs, which are uncommon on most computers.

However, following the steps below, you can manage to connect the projector to your computer.

Step 1

Ascertain the computer’s video output format. The most popular ones are S-video, DVI, and VGA. You need to buy a cable or adapter that enables you to connect an RCA cable to the type of video-out connector your computer has after you know what kind it has. One ought should be available online for a few dollars.

Step 2

Switch off the projector and computer. Doing this whenever you attach gadgets to your computer is a brilliant idea. If the projector has recently been used, give it time to cool down. This safeguards both you and the internal workings of the projector.

Step 3

Using the proper connection and adapter, connect the computer to the projector. You must also connect an audio link to the computer’s headphone or audio line-out jack if you want to use the projector’s speakers. You’ll need an adaptor if you want to connect a conventional 3.5mm dual male audio cable to the projector’s RCA connection.

Step 4

 Start the projector and computer. Your computer’s video output should be set to the external monitor mirror mode. The image on your computer screen will appear on the projector as a result. The “Fn” key and one of the “F” keys at the top of the keyboard are typically used in combination to cycle between the video options.

The particular key changes depending on the type of computer, but it should have an icon of a monitor on it. The video output option is also available in the video settings menu when you access the control panel.

Below are some alternatives to the Discovery Wonderwall Projector:

BenQ HT2050A

The BenQ HT2050A is not cheap, but it is the best alternative to the Discovery Wonderwall Projector.

This modern projector creates a vivid image with excellent contrast and true-to-life color accuracy. In addition, it has a vertical lens shift, which simplifies the setup compared to the other equivalent models.

The majority of media players, PCs, gaming consoles, Macs, and mobile devices are supported, and it has a variety of input choices, including HDMI and USB. Additionally, the projector has a 16ms input lag that is low enough for immersive gameplay.


The diminutive P8 performs far larger than its size would imply. To be honest, the hand-held size can imply that it could even display a picture. However, it only costs $250, has a built-in speaker, and is moderately bright. Impressive.

Both battery and streaming apps are absent from it. You must therefore take that into account. It does, though, contain a USB port and an HDMI input, allowing you to connect a streaming stick and access any streaming programs you might need.
