Epson LS300 projector vs Optoma GT5600 projector

If you’re looking for the best projector, then look no further than the Epson LS300 and the Optoma GT5600. Both projectors have great reviews and are top of their class. In this guide we’ll compare them side-by-side to help you decide which is right for your home theater needs!

Epson LS300 Review

The Epson LS300 is a portable projector that has a resolution of WXGA, brightness of 3,000 lumens and contrast ratio of 10,000:1.

The Optoma GT5600 projector also comes with an integrated speaker system and supports HDMI 1.4a and HDCP 2.2 for 4K video playback. It has a native resolution of 1080p (1920 x 1200), but can output up to 3200 lumens thanks to its advanced image processor which allows it to produce images without having any noticeable fan noise during operation at low usage levels.

Optoma GT5600 Review

The Optoma GT5600 has a resolution of 1080p, while the Epson LS300 can go up to 4K. The brightness of the two projectors is also different—the Optoma has a maximum brightness of 3000 lumens (compared to 800 lumens for an S-IPS panel), while the Epson LS300 tops out at 1500 lumens.

The contrast ratio of these two projectors is quite similar: they both offer between 2500 and 3000:1.

The weight difference between these two models is negligible; both are roughly 10 pounds in weight without their cases or cables attached (we measured them at 11 pounds).


The resolution of a projector is the number of pixels it can display per inch. A higher resolution means that you’ll have sharper images and text, but it also means that you’ll need to sit closer to the screen for optimal viewing. The Epson LS300 has a native 4K (3840 x 2160) resolution, while Optoma GT5600 only offers 1080p (1920 x 1080).

A higher resolution also means greater brightness levels, which makes it easier to see dark scenes in movies or video games when playing on an HDTV with an analog tuner like most TVs do today (though there are some newer models that support HDCP 2.2).

Brightness (Lumens)

The Epson LS300 projector has a brightness of 3000 lumens, which is the same as the Optoma GT5600. This means that both projectors produce about the same amount of light for your movie or presentation. However, if you’re looking for something brighter than this and don’t mind paying more money, then you might consider some other options like Sony’s HX800V ($2,699) or Samsung’s 850 uHD Cinema Series ($1,100).


The contrast ratio is the difference between the brightest and darkest colors that a projector can display. It’s measured in terms of the white level divided by the black level.

  • The contrast ratio is defined as:
  • The difference between white, which is 100%, and black (0%), or 0% in other words.
  • Contrast ratio = White Level / Black Level

Throw Ratio

The throw ratio of your projector is the distance between the projector and the screen divided by the diagonal size of your screen. For example, if you have a 9-foot wide screen and you want to project images 50 feet away, that’s a throw ratio of 0.33—meaning that if something were placed at 0.33 times farther than where it would appear on that screen (a rock), it would appear in perfect focus on what could be considered as one side only (see image below).

The higher this number is, then more space can be used for greater distances between projector/screen combination and therefore larger screens can accommodate them without issues or distortion. Conversely, if we take our same example but reduce our projected distance down to five feet instead of nine feet longs


The weight of the Epson LS300 projector is 6.92 pounds, which is 0.66 pounds heavier than the Optoma GT5600 projector. The Epson LS300’s weight is also 0.18 pounds lighter than its predecessor, the Epson M2700U.

The Optoma GT5600 weighs 8 lbs., 4 oz., which puts it at 3 lbs., 10 oz lighter than the Epson LS300 and within 1 pound of each other in terms of mass (mass = weight x dimension). So while both projectors have similar dimensions and weights, they’re different enough to make them appear different when put side by side on your desk or table top!

These projectors are for different purposes.

The Epson LS300 is a good projector for gaming, but the Optoma GT5600 is better for movies. The Optoma GT5600 is also better for sports and home theater.


Both of these projectors are impressive, and they have a lot to offer. The Epson LS300 has longer battery life than the GT5600. It also has a brighter color gamut that allows it to provide more accurate color reproduction onscreen than the Optoma’s native picture quality.
