Projectors deliver a true theater experience at home. Enjoy movies, TV shows, sports, and video games on a screen measuring up to 10 feet or more.
In a Nutshell
You can place a projector on a coffee table or out of view on a bookcase or shelf in the back of your room. Or you can ceiling mount it.
Projector screens can be free-standing, wall-mounted, or retractable. You can skip the screen and project movies directly onto a wall. That generally looks OK, but a screen delivers a smoother, more consistent image.
Most projectors also have no way of producing sound. To watch a Blu-ray movie, connect your player's video output to the projector, and run the audio to an A/V receiver.
If you want to avoid running cables from your video source(s) to a projector, consider a projector with wireless HDMI.
To give yourself more placement options, look for a projector with lens shift. Lens shift allows you to move the projected image up or down, left or right, while keeping the projector body stationary.
Projectors provide the ultimate home theater experience. Nothing else comes as close to truly re-creating the viewing experience of a movie theater. We often talk about how a bigger screen is the most impactful upgrade for TVs. Projectors make it possible to enjoy images that are much larger than even the biggest TVs offer.
A projector is really a two-piece system: the projector and the screen. Today's digital projectors are a snap to set up and use. Many models are compact and lightweight enough to be considered portable.
You can place a movie projector on a coffee table or out of view on a bookcase or shelf in the back of your room. Or you can ceiling-mount your projector (we have mounts for most of the models we carry).
Projector screens come in a variety of sizes, and can be fixed-frame or retractable (manual or motorized). If your budget is really tight you can skip the screen and project movies directly onto a wall. That generally looks OK, but a screen delivers a smoother, more consistent image, and helps any projector perform at its best.
This is especially true for the HD and 4K home theater projectors we carry, which provide picture quality that's far superior to that of typical business-oriented projectors.
A home theater projector is a practical, cost-effective way to enjoy cinema-like picture size and quality at home.
Projectors contain only the essentials for creating the most cinema-like picture possible. Typically, a high-resolution LCD or LCoS imaging chip (Sony calls their LCoS technology SXRD), an ultra-high-intensity lamp, superb video processing and scaling circuitry, top-grade lenses with versatile zoom capabilities, and several video inputs.
What you won't find is any type of built-in TV tuner or web streaming apps. Popular video sources include Blu-ray players, satellite receivers or cable boxes, video game consoles, and media streamers like Apple TV® and Roku.
Projector vs. TV
Aside from producing spectacular images, projectors are often a better value than enormous flat-panel TVs if you figure the cost per inch of screen. And because you're projecting the image onto a wall or separate screen, there's no glass involved. You'll see no reflection or glare from the screen.
Even large flat-screen TVs appear small compared to the huge images you can get with a projector system.
That said, most projector owners also have at least one TV. The projector experience is unbeatable for movies, sports, or any other viewing where you're really focused on what's happening on the screen. But if you just want to catch a few minutes of news before bedtime, firing up a projector rig can be a little inconvenient.
Is a projector for you?
There are a couple of key things to be aware of if you're considering a projector. First, your room lighting: for the best projector performance in a home theater, try to reduce or eliminate light in the room, whether it's daylight or room lights.
Rooms with few windows are good candidates, especially if your viewing is heavy on movies. If you plan to use a projector in a room that gets a lot of sunlight, you may decide to limit your viewing to after dark. Or consider installing blackout shades on the windows.
Thanks to today's brighter projectors, and special screens that reject ambient light, you can enjoy a crisp, colorful projected picture even in rooms with some lights on.
Many LCD projectors, like the Epson models we sell, can produce very bright images that look good even in rooms with some ambient light. And there are special projector screens designed for use with the lights on. These screens have optical coatings that reject ambient room light and only respond to the light produced by the projector. Screen Innovations' Slate® and Black Diamond® models are great examples of this technology.
Second, your viewing habits and the life of your projector's lamp: today's projectors have a typical lamp life of 2000-5000 hours. The hour rating actually represents the lamp's "half-life" — the point where its brightness has diminished by half. A lamp will still work past its half-life, but it will continue to gradually lose brightness.
When you replace the lamp (it's easily user-replaceable), picture quality returns to like-new brightness. But you won't be able to simply run to the hardware store for a lamp. These projectors use special high-pressure lamps that cost between $200 and $500.
Projector owners who mostly watch movies and special events run their projectors an average of about 8 hours a week. For a projector with a 2000-hour lamp, that translates to 4-5 years of use. But if you use a projector as your main TV, logging say, 4 hours per day, you'll be looking at lamp replacement in under a year and a half.
Projectors have the same video inputs you find on TVs, including HDMI for high-def video sources like a Blu-ray player.
How to choose the best projector for your room and viewing habits
These days, the projectors from major manufacturers all look impressive. But each has its own unique strengths and weaknesses, and no single model will be the best choice for all rooms and signal sources. You can get a general idea about how a projector will perform by comparing these three key specifications.
Resolution: The number of pixels on the imaging chip measured from side to side and top to bottom. Nearly all high-definition projectors made for home theater use are full HD 1080p — 1920 x 1080 pixels. We now carry some 4K Ultra HD projectors with 4096 x 2160-pixel resolution — over four times the detail of full HD.
As the resolution gets higher, the size of each pixel gets smaller, so that images look more seamless, with less noticeable "pixel structure." A projector's built-in scaler will upconvert or downconvert all incoming signals to precisely match its "native resolution."
A few manufacturers make "pixel-shifting" 1080p projectors that provide compatibility with 4K video sources. The picture doesn't have the same quality as a native 4K projector, but definitely looks sharper than 1080p.
The increased picture detail, clarity, and depth of 4K is easy to see on projector-sized images.
Picture contrast: Contrast is arguably the most important factor of picture quality. The contrast ratio spec measures the difference between the whitest whites and the blackest blacks a projector can show. A higher contrast ratio can result in a picture with deeper blacks and more subtle color detail.
Good contrast is critical for home theater projectors. Many models have several lamp settings that let you reduce brightness and boost contrast for the best viewing in a darkened room. Some 4K projectors include HDR (High Dynamic Range) capability. They can decode HDR-enhanced video sources like Ultra HD Blu-ray and provide exceptional picture contrast.
Light output (brightness): Home theater projectors typically have brightness ratings of 700-2500 lumens. All projectors have plenty of brightness for watching movies in a dimly-lit or darkened room. A higher brightness rating will come in handy for viewing when there's more ambient room light. Higher brightness also helps if you're projecting onto a wall (it's less reflective than a screen), or if you're displaying an extra-large image (110" or bigger).
3D: If you've seen a well-made 3D movie in a theater you know that 3D works well with projected images, and that's true for home theater projectors, too. Bright projectors improve 3D because the 3D glasses dim the picture noticeably. You don't need a special screen for 3D, although a more reflective surface — indicated by a higher "screen gain" spec — will help 3D images look bright and crisp.
A few of Epson's projectors include wireless HDMI technology so you can avoid long cable runs. You plug your video sources into the transmitter module, which sends the signal to the wireless receiver built into the projector.
Wireless HDMI: Some movie fans who want to upgrade from a TV to a projector may hesitate because of installation issues. Mainly, how to connect their components to the projector without running cables across the floor. Epson has the answer with their projectors with wireless HDMI.
Epson's wireless receiver is built into the projector chassis, while the small transmitter module is placed near your video sources. Just connect an HDMI cable between your component and the transmitter and you're done. The transmitter sends a flawless picture wirelessly between the transmitter and the projector. Both must be in the same room, and the range is about 32 feet.
Lens shift: Another feature that makes installing a projector easier is lens shift. It allows you to move the projected image up or down, left or right, while keeping the projector stationary. This opens up more placement options because you can position the projector off-center in relation to your screen and still get a perfectly true image.
Shop for projectors with lens shift.
Projector placement tips
Most folks use their projectors mainly for "event viewing" — movies at night, and the occasional sports broadcast. If that's your plan, the simplest option is to set up the projector on a table or other flat surface. You can keep it stowed away in a closet or cupboard when you're not using it.
Remember: most projectors have no sound capability. So, to watch a Blu-ray movie, you'll need to connect your player's video output to the projector, and run the audio to your A/V receiver. And speaking of sound, if the projector will be located near you, look for a model with a quiet cooling fan.
If you have more of a dedicated home theater in mind (or if you want to keep your projector out of the reach of small children), you can ceiling-mount it. This makes for a neat, uncluttered look, but it does call for some DIY skills.
We carry ceiling mounts for most of our projectors, so that part is straightforward. But, the projector also needs AC power, plus a video connection from any source you want to feed to it. It's not a problem for new construction, or if you're remodeling, but trickier in a finished room (especially if there's not an attic overhead).
Check out our guide to in-wall wiring for installation tips, or consider a projector with wireless HDMI.
A projector's image doesn't follow the lens precisely, like a flashlight. The image is offset a bit to allow placement on a table or ceiling mounting. The image is raised somewhat for table placement, and similarly lowered for ceiling mounting. Note that for ceiling mounting, you typically flip the projector upside-down.
A quick look at installation considerations
As you compare projector features and performance, it's also a good idea to keep a few installation issues in mind. First, try to have at least a rough idea of how large an image you want to project. That will affect the distance between the projector and your screen.
With any projector, the further you position it from your screen, the bigger the image will be. But different projectors have different "throw ratios." The throw ratio is the relationship between a projector's distance from the screen and the width of the image.
A projector with a "short-throw" lens projects a larger image for a given distance from the screen. That's a smart choice for smaller rooms where the projector will be relatively close to the screen. Long-throw projectors are best for ceiling-mount situations where the projector will be placed further back in the room, behind the viewing position.
If your projector will be ceiling-mounted, it's important to make sure the lens is parallel to the screen. That helps ensure that your image will be true, with straight edges on all sides. If the projector and screen aren't correctly aligned, the image will look like a trapezoid instead of a rectangle. The top of the image will be wider than the bottom, or the left side will be taller than the right side, for example.
Fortunately, there are two ways to fix picture shape: lens shift and keystone correction. Lens shift lets you tweak the position of the lens inside the projector, so you can compensate for your projector being slightly off-axis.
Keystone correction adjusts the image's shape using internal processing that can slightly degrade the quality of the image. Nearly all projectors offer keystone correction, but only some offer lens shift.
Finally, consider the fact that the high-output lamps in projectors generate a lot of heat. Wherever you end up placing your projector, be sure to leave plenty of space around it to ensure proper ventilation.

Ultra Short Throw projectors like Epson's Home Cinema LS100 can be placed directly under the screen. There are no hassles with ceiling mounting or long cable runs between your components and the projector.
Ultra Short Throw projectors
Ultra Short Throw (UST) projectors can help you enjoy the big-screen projector experience in rooms where it might not otherwise be possible. The design of a UST projector simplifies installation because you can place it directly under the screen, on a low table or credenza.
A UST projector can actually sit on top of your A/V equipment cabinet, right next to your video sources. So you don't have to worry about long cable runs between your components and your projector. Plus, it's just about impossible for anyone to walk in front of the projector.
It's a good idea to use a screen with any projector, but it's absolutely essential for a UST projector. A UST's lens design and steep projection angle will magnify even minor surface imperfections, so projecting onto a wall is going to look pretty rough. A high-quality fixed-frame screen with white or gray fabric should work well in most rooms.
Don't forget the screen!
To get the best picture quality from any projector, you should get a screen that is a good match for your projector and room. Read our projector screen buying guide and then shop for a projector screen.
