How to Make a Projector Brighter- Best guide in 2023

Unlike physical screens like LED and LCD displays, projectors tend to work a little differently as their mechanism works by projecting countless rays of RGB colors which are calibrated to portray an image from a lamp source.

But there are many elements that come into play by hindering this mechanism during the initiation of the process of light projection. These factors affect the image quality depending on how you tweak it. 

Although if you are an individual who is negatively impacted by these factors then you might be wondering why your projector isn’t as bright as it is supposed to be.

But worry not because this guide will show you all the culprits that you can counter and how to make a projector brighter so you can enjoy your life with brighter colors.

How to Make a Projector Brighter

1: Increasing your lumen brightness.

Depending on the brand of your projector, each multimedia device comes with its Lumen brightness ratio which you can tweak to gain brighter intensity, these brightness can range from 2500 to 10000 Lux to deliver better and brighter results.

By default, your projector must have it tuned down the notch, and all you have to do is dial it back to the highest option in the brightness settings and increase it depending on your requirements. 

Note: setting a higher brightness option can also shorten the life span of your bulb and is also harsh on your electrical bills due to more energy consumption

2: Adjusting the ambient lightning

Although this is pretty much a common sense thing, still if it’s your first time or hasn’t had the experience dealing with a projector, it is highly advised to choose a room where external stimuli like sunlight aren’t affecting your image projections and canceling out its brightness to make it look dull. 

If that is the case and your projector is struggling with low lumen brightness issue, all you have to do is turn on the blinds of your room by covering the windows and other possible places that might give a path to ambient lighting.

Moreover, it is also advised to turn off any lighting like bulbs, lamps, and other such things that might compromise the projector lighting. 

3: Lamp running out of life spans

A projector cannot work without a light source which is usually an LED, Metal Hallid, Halogen, Laser, or a hybrid one. Every projector needs some sort of illumination source to throw light across the room and with the generation of light, there is also some sort of kinetic energy that takes a toll on the life span of the bulb.

As every bulb comes with designated hours ranging from 3000 hours to 10000 hours depending on its quality and design. After a bulb has hit its expiry date, it will result in low brightness production which will make the imagery look dull.

To fix this problem all you have to do is invest in another bulb and your projector will be back on its feet in no time.

4: Changing the power conservative modes

This one is a little tricky and is easy to miss especially if you are a rookie, as many projectors depending on the brand and quality tend to come with Eco mode or quiet mode by default.

This mode ensures you get the best life span, and less energy consumption all at the expense of lower brightness by default. 

Moreover, these  Modes also prevent from the projector working overtime by underclocking it which limits the heat generation and makes the fans turn at a slower rate resulting in quiet mode.

The solution is simple, just go into economy settings which will be listed in your manual and turn off the power saving mode or quiet mode which will automatically fix the low brightness of your projector and you are good to go.

5: Changing the projector screen color

This one impacts the most out of every other solution listed above, as rays hitting the screen tend to either deflect or absorb depending on the color of the screen.

For example, a darker screen color like black will absorb most of the colors which will make your image look dull no matter the brightness intensity you use. 

So it is highly advised to use a whiter screen color that has a ratio of light reflection to give you the best-looking image quality without any absorption of light rays.

6: General cleaning of your hardware

Last but not least is a problem pretty much about common sense, as dust things build up and clog your machinery like a projector lens, the light rays are blocked in their path which makes the image look dull.

The fix is a brainer and all you have to turn off your home theater and take a nice piece of microfiber cloth to clean the innards of your projector lens from the dirt and debris stuck on it coming from the intake fans.

I think that’s pretty much all there is to it, either of these adjustments will result in a brighter light source, so long as you follow the instructions listed above carefully. 


I have collected some questions and answered them to help you clear your remaining doubts.

Q: How to Increase Projector Lumens?

A: The answer to this question is quite simple, all you have to do to increase the lumens of your projector is simply change the bulb.

Q: Can I Use A Different Bulb Type For My Projector?

A: Yes, you can use different types of bulbs for your projector, however, you should keep in mind that the type of bulb you choose must match the wattage rating of your projector.

Q: How Many Lumens Outdoor Portable Projectors Need?

 A: There are various factors that determine the number of lumens required by your outdoor portable projector. These include the size of the screen and the distance between the projector and the screen. But the ideal number of lumens to expect is around 1000 to 2000 lumens.

Q: What Is An Optimum Screen Size For My Projector? Do I Need To Get One?

A: Well, it depends on the size of your room and the distance between the projection surface and the screen. If you want to get the best possible picture quality, then you should get a bigger screen, as the closer the screen gets to the projection surface, the smaller the angle of view becomes. For a more detailed explanation.

Q: How Bright Should My Projector Be?

A: As mentioned earlier, the more lumens you want to project onto your wall, the better the picture quality will be. However, if you are planning to watch movies on your projector then you don’t really need too many lumens, as you would be watching it in dark rooms anyway.

Q: Does a projector screen make it brighter?

A: No, they won’t make it brighter, however, they may affect the overall appearance of the projected image.

Q: Will Using A Wall Mounted Projector Help Me Get Better Picture Quality?

A: Yes! It will definitely help you get better picture quality.
