RCA projectors can offer you a real theatre experience in your home theatre. RCA is notable for multimedia projectors, and people enjoy using them for their home theatre.
Regardless of the quality, you may purchase one, set it up at home, and realize that the projection appears blurred. If you notice something like this, do not be alarmed. It would be silly to think that you have purchased a faulty projector. Although this could be true, most projector users encounter problems like this which usually requires a simple fix.
How to focus RCA projector. RCA projectors have a focus knob on the projector that can be adjusted to change the device’s focus. You can adjust the keystone correction to focus near the edges of the screen. Adjusting the projection distance can also help adjust your RCA projector’s focus.
The image of your RCA projector will appear blurred for several reasons. In this article, we will look at why your RCA projector is out of focus and possible ways to focus them on getting a clear picture.
Why is My RCA Projector out of Focus?
When you notice that your projector is out of focus, it could be due to the following reasons:
A Wide Projection Distance
If you mount your projector beyond the required distance based on your screen’s size, your image will appear blurred. RCA has given a recommended projection distance users are supposed to use. Anything more than this will make your projection very blurry.
You can fix this by adjusting the projection distance to get a clear and focused image.
A Distorted Image
Distorted images can sometimes make your image appear blurred at the edge of the screen. The image becomes distorted when you mount the projector at a certain angle, making one side of the projection appear longer than the others.
The stretching of the image at one side can make it appear blurred. You can fix this by adjusting the keystone correction.
A Dirty Projector Lens
When your projector lens is smeared with moisture or has debris like dust on the screen, it will interfere with the focus of the image. Simply wiping the smear off the lens will fix this issue.
How Do I Fix a Blurry RCA Projector?
Adjusting the Focus on an RCA projector is no difficult task. If you have figured out what caused your projector to be out of focus, the next thing is to find a solution to it. Here is how to adjust the focus of your RCA projector:
Change the projection distance
The projection distance is very important, and most of the time, projector users ignore it. Ignoring the distance between your projector and the screen can blur your image.
RCA has provided the required distance that should be used when mounting your projector. The distance and the screen size are provided in the table below:
| Distance (m) | Screen Size (inch) |
| 1.16 | 37 |
| 1.35 | 45 |
| 1.51 | 50 |
| 1.81 | 60 |
| 2.15 | 72 |
The distance is a rough estimate and does not necessarily need to be the same. If your screen’s size is not in the list, adjust the distance at the distance that corresponds to the size that is close to your screen’s size.
Keystone correction on RCA projector
Use the Keystone correction to correct any distorted image. As I said in the previous section, a distorted image will appear blurred at the side of distortion. Any distortion will be corrected with the keystone correction, and the projected image will appear as a perfect square or rectangle.
You can correct the image distortion by adjusting the vertical dimension and then later the horizontal dimension by turning the projector left or right to get a perfect rectangle or square.
The vertical dimension can be adjusted by turning the projector’s stand knob to tilt the device up or down. You can release the front leg by pressing the “Push” button under the device.
Most RCA projectors, like the RPJ129 model, come with a keystone correction knob behind the device that can be used to adjust the keystone.
Using the Focus knob to focus the device
Depending on the model of RCA projector you are using, the location of the focus adjustment knob will differ. With the RPJ129 model, you can adjust the focus by turning the lens. Other models have an adjustment knob on top of the projector.
Turn the knobs while looking at the screen until the pixels appear finer. This method can come in handy when you cannot adjust the projection distance, especially when using the device in your room or it has been mounted to the ceiling.
Clean the Projector’s Lens
If your projector is still out of focus after trying out the previously listed solutions, your projector lens might be dirty and needs cleaning. Cleaning the lens is no difficult task, but caution must be taken to avoid damaging or scratching the screen.
Preferably, use cotton to swab to clean the lens. RCA projector lenses usually come with a cover that is supposed to be in place when not in use. Make sure to cover the lens anytime you finish using it to prevent foreign materials from smearing the screen.
What If None of the Solutions Did Resolve the Problem?
If none of the solutions work for you, try out these alternative fixes:
- Change the projector’s lens as it may be scratched. If your warranty has not expired, take it back to RCA for servicing, otherwise, take it to a technician and get it changed.
- Change your projection surface or projector screen. Make sure to use a crease-free and smooth screen.
- If the connected device is a computer, change the resolution settings to match that of the projectors. Scaling can reduce image quality and make them appear blurred.
If none of these work, contact a technician to conduct further troubleshooting on the device to know what is wrong.
Final Thoughts
RCA projectors are one of the projector brands that are a great fit for home theatre. However, getting an adequate projection distance could be an issue due to the small size of a viewing room at home.
When facing this issue, adjust the focus knob on the projector to get a clear and sharp image. If you are sure of the projection distance according to your screen size, other causes could be a dirty projector lens or a distorted image.
