Home Theater Projector Specs
A home theater projector gives you an immersive experience for watching movies, sports or gaming. But with so many different models, you can easily get lost in a sea of specifications.
Some are lamp-based and some use laser technology. Both have advantages. Lamp-based projectors typically have lower contrast and black levels, while solid-state units offer longer life and a brighter picture.
Picture Quality
Depending on where you plan to use your projector, image quality is one of the most important factors. If you plan to use it primarily in a dark room, look for a projector with high enough brightness to stand up to ambient light at your desired image size. Brightness specs can be exaggerated, so we recommend relying on measured results from trusted reviewers.
We also look for a projector with good contrast. The higher the contrast, the better the projector will be at displaying black levels and showing details in shadow areas.
Many home theater projectors boost color brightness at the expense of accuracy, but top-rated models like BenQ’s HT3560 deliver spot-on colors along with excellent contrast and HDR support. This model’s CinematicColor technology delivers a wide color gamut, while its new HDR10+ feature automates what’s usually a manual setting for HDR content and dramatically improves shadow detail and image contrast. It also takes into account the screen’s surface gain to maximize dynamic range. Those features, plus its native 4K resolution, make this an excellent choice for a top-rated home theater projector.
Brightness
The brightness of a home theater projector is important because it determines how well the device can project images on a screen. Brightness is measured in ANSI lumens, which is the most accurate and reliable way to compare the performance of projectors. You may also see a projector’s brightness specifications listed in lux, nits, or watts, but ANSI lumens is the most common and is considered to be the gold standard.
The highest quality projectors in a price class typically offer a maximum of 2,500 ANSI lumens. This brightness level is ideal for dedicated home theaters lcd projector for classroom in rooms with very dark ambient light and good control of lighting.
However, if you have a family room with ambient light or larger screens, then consider models that offer 3,000 or more ANSI lumens. They will work best in those environments and provide more flexibility for use with different types of content. Some of these models will even automatically optimize brightness for SDR, HDR, and HLG content to improve contrast and shadow detail. BenQ’s 4K HT3560 is an example of this and is one of our top-rated projectors for home theater in its price range.
Color Accuracy
The color accuracy of a projector refers to how well it displays the colors that appear on the screen as they should. The best projectors meet certain standards and can show you the colors the filmmaker intended you to see. Lots of budget models, on the other hand, serve up oversaturated and unrealistic colors that pop off the screen but aren’t true to the original footage.
The majority of home theater projectors are Digital Light Processing (DMD) models that use tiny mirrors to reflect light onto the screen and a spinning color wheel to display different colors. Some DLP models can cause a rainbow effect in some viewers; we only recommend models that don’t suffer from this issue.
We test every model we review for contrast ratio, image uniformity, color accuracy and brightness. In our labs, we place each projector in a dark Home LCD video projector room with a 100-inch screen to assess these qualities objectively. We watch movies and TV shows, comparing the models to each other and side-by-side against their direct competitors. We also look for a wide range of features, including easy setup tools and advanced settings to tweak the image and audio for your own preferences.
Reliability
When shopping for a projector, look for one that provides good contrast ratio, high brightness and excellent color. A good quality projector will also have an onboard audio system that produces sound that’s clear and crisp enough to use for movies, TV shows and presentations.
A home theater projector can be wall- or ceiling-mounted. Some models are small enough to be portable, while others offer HDMI inputs for connecting Blu-ray players, satellite or cable boxes, video game consoles and media streamers such as Apple TV and Roku. Many offer built-in Wi-Fi, although it’s best to use a separate router to get the most speed and range.
Most projectors use LCD, or digital light processing, technology, while higher-end ones use LCOS, or liquid crystal on silicon, designs. Some have a dynamic iris that adjusts the amount of light being projected to improve contrast scene by scene. Other models feature three LCD chips that are guaranteed not to show rainbow artifacts, the red/green/blue flashes some single-chip DLP projectors can produce.
Portability
With their smaller dimensions and light weight, portable projectors are easy to move between rooms or even take outdoors. Some also include batteries or USB-C ports for running off a power bank. This versatility allows you to create a home theater at work, school, or a friend’s house without having to worry about access to a power outlet.
When looking for a portable projector, be sure to check its contrast ratio, which measures the difference between the brightest and darkest areas of an image. A higher contrast ratio produces more vivid and realistic images.
The JVC DLA-NZ8 is a great example of a high-quality, portable projector that offers both HDR support and powerful contrast ratio. Its three-chip D-ILA design prevents the rainbow artifacts that plague many single-LCD models and its 8K e-shift processing delivers a sharp, lifelike picture.
