In this Guide you will get actual differences and similarities between 720p vs 1080p projector, also you will know the purpose of buying.

We have been listening to lots of myths about 720p is better than 1080p or 1080p is better than 720p for HDTV, gaming, blue-ray DVDs, etc. Without knowing the fact we can’t make a buying decision.

After some practical experiments, we are come up with the actual data to distinguish between 720p and 1080p.

720p vs 1080p Projector-The Major Differences.


Pixels Difference in 1080 and 720p projector

Pixels play a vital role to provide you sharp and detailed picture quality on a big screen. As 1080p comes with 1080 horizontal pixels and 1920 vertical pixels, if we multiply both we will get 2.073 Million pixels.

However, 720p has 720 horizontal and 1270 vertical pixels if we do multiplication we will get 0.914 million pixels.

Greater the pixels, greater the sharpness, and details you will get in a bigger picture, as 1080p has more than twice pixels as compared to 720p, defiantly the difference will be visible on a larger screen of 100 or 120 inches, however, on a small screen of 40 to 50 inches, you may not find a visible difference.

The difference is obvious 1080p performs way better than 720p in terms of sharpness, details, and sometimes in brightness, still your projector adjustments, screen size matters a lot, I have a 720p projector which performs amazingly on a smaller screen.

Picture Quality:

Picture Quality of 720p and 1080p projector

1080p utilizes more than twice pixels as compared to 720p you will found a noticeable difference in sharpness if you are watching on a bigger screen, however in the medium or smaller picture you may not found a huge difference.

Other than that, in some experiments, we have found that the contrast ratio and blacks of the 1080p home projector perform well in the bigger picture just because of more pixels.

Screen Size:

We can’t find a noticeable difference between 1080p and 720p in a 40-50 inches screen, however, when we increase the screen size the sharpness and details of 720p drastically decreasing, however in 1080p the details remain the same even in 100 inches screen.

720p contains fewer overall pixels defiantly you will not get that sharper picture quality on a bigger screen, if you want to enjoy in smaller screen you are good to go with even you can’t differentiate between 1080p and 720p on a smaller screen.


Since gaming needs a bigger picture, you will get all ingredients in 1080p to skyrocket your gaming experience, however, you can do gaming in 720p but we recommend you to go for 1080p. as newer consoles also encourage gamers to go for at least 1080p to explore the real sharpness, details, and brightness of games.

Blue-ray performances:

Most of the blue-ray DVDs come with a 1080p resolution; you should go for a 1080p projector to enjoy the actual blue-ray experience.

HDTV and Streamings:

According to our experience most of the streaming’s and HDTV provider uses 720p or 1080i resolution, even premium streaming providers are struggling to provide 1080p support. Though you can found a few which provide 1080p full HD support they will be expensive.

It is wise to use a 1080p projector with 1080p full HD steaming, but if you have 720p or 1080i you may not notice a huge difference between a 1080p and a 720p projector. Though 1080i will perform slightly better in 1080p, still not worth spending more money on.

Getting a 720p projector will be a good choice to operate 720p or 1080i streaming.

DVDs performances:

Like streaming provider, DVD’s mostly comes with 720p or 480p resolution; however, you may get a few with full HD 1080p resolutions.

Definitely, a 1080p projector performs way better than 720p with a 1080p DVD but don’t expect to get that much quality even in 480p or 720p DVDs because 1080p projectors try to scale 720p to 1080p which will ruin the picture quality.

Better to go for a 720p projector if you want to operate only 720p or 480p.


Defiantly the more the quality the more you will have to pay, 1080p projectors are costly as compared to 720p.

Which Is Better For You?

It depends, you have to identify the purpose of use, if you are going to watch your serials, play games and other kinds of stuff on 720p resolutions with the average screen size of 40-50 inches from 8-10 ft. away you are good to go with 720p.

On the other hand, if you are going to play games and watch whole things in full HD 1080p with a 100-120 inches big screen from 15-20 ft. away, you should go for a 1080p projector. Make sure that you should have proper 1080p HDTV streaming, blue-ray DVDs or 1080p supported consoles to explore real HD otherwise you will get scaled picture quality.

Over To You

During some experiments we have found some 720p projector performs pretty awesome on a smaller screen, in terms of bright colors and contrast, literally, we can’t see any difference between 1080p and 720p.

We have concluded that if someone is willing to use the projector with a 40-50 inches screen it is best to go for 720p because the only major difference is pixels, there is no need to spend more if we can do your work with 720p.

Hope we have provided you a fair comparison between 720p and 1080p.
