Why do the size and layout of the home cinema room matter?

Room size and layout are major factors to consider before buying your projection system. A projector is different from a Blu-Ray or DVD player.

In a front projection system, the projector casts (or “throws”—see below) the image onto the screen from a distance, either via a bulb or laser system. And because its job is to project the image, it must be placed a certain distance away from that screen to ensure a clear picture. Too close or too far away, the picture is unwatchable.

With rear projection, the projector sits behind the screen and casts the image forward onto the viewing surface. A significant issue with rear projection is the loss of brightness because so much of the light output reflects off the actual screen, back toward the projector. This will necessitate the purchase of a more expensive projector with an even higher brightness rating, plus you need to have the space behind the screen for the projector to throw the correct image size and a decent ventilation system installed to keep your equipment from overheating.

The only “throwing” here should be from your projector

In projector speak, manufacturers use the word “throw.” This is the distance a projector needs to be away from the screen onto which it will project the images. A short-throw projector can project a clear image onto a 120” screen from just a few feet away; an ultra-short-throw projector can do this from just a few inches away. Some people prefer short-throw and ultra-short-throw projectors when they don’t want to deal with ceiling or rear-mounted projection systems or when portability or accessibility is an issue.

The trade-off with a short- or ultra-short-throw projector? They can be expensive, and some just aren’t as sharp as their non-short-throw counterparts.

Let there be less light

Assess how much ambient light spills into your theater space. If the home theater has windows (as is common in a living or family room), your projection needs will be different than a custom home theater built in a windowless space, such as in a basement. The more ambient light, the brighter the projector will need to be (your projector will need to have a higher lumen count) and more modifications will need to be made to the space to close out that light for optimal viewing.

What projector is best for my theater?

In terms of projection technology, the market offers four major types of projectors for home theater:

1. DLP, or digital light processing projectors

The basics:

DLP projectors are typically the least expensive option for people looking for a budget projector. Cheaper DLP models have been known to create what’s called a “rainbow effect,” flashes of color across the screen. Some people seem to have problems watching movies played on most modern projectors that use DLP because of their brain’s interpretation of the RGB (red-green-blue) color sets. This inexpensive screen can still be a good option for budget-conscious home cinema lovers. A more expensive DLP projector can greatly minimize the rainbow effect.

The nerd-out:

A DLP projector produces its picture when light reflects off a chip that has millions of tiny mirrors affixed to it. Less expensive home and portable DLP projectors use only one DLP chip, which processes red, green, and blue—or RGB—light sequentially, one after the other, via a “color wheel.” (For context, most commercial movie theaters use three-chip DLP projectors as these higher-end machines can simultaneously process individual beams of RGB light, thereby producing bright, high-quality images.)

Highly reviewed and rated models:

  1. Optoma HD39HDR 1080p great for gamers and cinephiles alike- $799+
  2. Optoma 4K UHD, 1080p GT1080HDR - $799+
  3. BenQ CinePrime 4K HT3550 (2019) - $1499
  4. Optoma UHD60 True 4K DLP - $1679+
  5. Sony VPL-VW350ES 4K Ultra HD (their entry-level 4K projector) - $9,999

In terms of DLP brands, you can’t go wrong with Optoma, BenQ, Epson, JVC, and ViewSonic.

2. 3LCD, or 3 liquid crystal display chips 

The basics:

The 3LCD projectors offer a sharper image, a three-times-wider color gamut, and superior picture quality to their DLP counterparts. The 3LCD tech means no rainbow effect, plus it delivers a short lag time, which will keep your gamers happy. The brightness of the colors projected by a 3LCD system is vibrant and rich, which means you don’t have to worry as much about the ambient light spilling into your theater space. The 3LCD models are often the go-to choice for classroom and corporate environments (Panasonic is a leader in this category).

The nerd-out:

3LCD projectors have three separate LCD imaging chips. White light is split into three separate colors—red, blue, and green beams—and then each of these colors is filtered through its own LCD chip. These chips then work with a prism and dichroic mirror system to produce complete, clear colorful images. 3LCD projectors do not suffer from the rainbow effect as we see with single-chip DLP projectors. Further, they are more energy-efficient, offer better color reproduction, and better white and color brightness.

Highly reviewed and rated models:

As the industry evolves toward developing laser-based projectors, it would seem that Epson has cornered the market on these 3LCD projectors. Here are a few Epson projectors to consider:

  1. Epson Home Cinema 4010 4K PRO-UHD - $1999
  2. Epson Pro Cinema 4050 3LCD projector - $2399
  3. Epson Home Cinema 5050UB 4K PRO-UHD - $2999
  4. Epson Home Cinema 5050UBe Wireless HDMI 4K PRO-UHD Projector with Advanced 3-Chip Design and HDR10  - $3299

Also, make sure to check out the BenQ’s CinePro CinematicColor™ and HDR-PRO™ series for incredible 4K ultra-high def imagery.

3. LCoS, or liquid crystal on silicon

The basics:

Usually, the most expensive models are available to the consumer market, an LCoS projector also offers excellent image quality, superior high-resolution output, and deep black levels, which makes it a favorite among cinephiles. They’re a bit heavier than their counterparts, weighing in at 10-12 lbs. You’re also not going to have to deal with the rainbow effect mentioned above, though some motion blur is possible (not great if you’re using it for gaming).

If money is no object, an LCoS projector is a serious option for your custom home theater.

The nerd-out:

LCoS projectors are considered a hybrid between the DLP and 3LCD technologies. These projectors use reflective technology but instead of mirrors (as with the DLP), it uses liquid crystals. It doesn’t have a color wheel, and LCoS-based projectors typically employ three LCoS chips, like the 3LCD, to modulate and deliver the distinct color channels (red, green, and blue).

Highly reviewed and rated models:

  1. Sony has a gorgeous array of LCoS 4K HDR projectors in the SXRD line, arguably among the best projectors in the business.
  2. Another leader in this category is JVC with their D-ILA line. The entry-level LCoS home theater projector is the DLX-X35, but JVC has recently introduced the world’s first e-shift 8K projector with the DLX-NX9.

4. Laser

The basics:

The home theater projectors listed above use lamps as the light source for their image projection. High brightness can be a concern, so look for projectors with a high enough lumen output to satisfy your needs on the big screen. Remember too that lamps use bulbs—and bulbs burn out.

The nerd-out:

To address the short bulb lifespan, the projection industry has developed laser technology to replace the bulb-lamp system. Laser technology provides fantastic image quality (some say even better than an LCoS projector). While the laser projectors still use the DLP or LCoS chip system, the laser is the light source for the projection tech. This will not only give rich color for the viewer but also accurate colors.

Instead of using the RGB lighting system to project colors onto the screen, a laser projector generates the exact colors it needs to build the picture. This translates to a brighter on-screen image and impressive color accuracy and black levels, and it’s remarkably energy efficient when compared to its bulb-using counterparts. A laser projector will last about 20,000 hours whereas a traditional bulb will usually last around 2000 hours.

Again, laser projectors can be pricey, but if a bright image, and color accuracy is really important to you, the technology is superior here.

Highly reviewed and rated models:

  1. Optoma Cinemax P1 Smart 4K UDH laser cinema ultra-short-throw projector with integrated soundbar  - $3299
  2. LG CineBeam HU80KA 4K UHD laser projector - $2696+
  3. Optoma UHZ65 HDR XPR Laser DLP - $3999
  4. Epson LS100 Full HD 3LCD Ultra Short-throw Laser Projector - $2999

As with the other projectors noted above, top brands continue to be Optoma, BenQ, Epson, JVC, Sony, LG, and ViewSonic.

What is the best home theater projector for the gamers?

Video games are a different beast from films. When you’re choosing a projector, it’s imperative to consider input lag. Input lag is a hot-button issue for serious gamers as it describes the lag time that happens between the gaming system sending the frame to the monitor (or projector, in this case) and the monitor/projector displaying that frame. A lag time of fewer than 15 milliseconds for your projection screen is preferred.

To combat excessive lag times for your gamers, industry experts recommend DLP projectors. Here are a few:

  1. Optoma GT1080Darbee
  2. BenQ HT2050A

Both these Optoma and BenQ models offer low input lag times of less than 20 milliseconds, which is right in that sweet spot, and a lot better compared to a traditional projector. It bears noting that most 4K modern projectors have an input lag of higher than 40 milliseconds, which might drive your gamer up a wall when in the heat of battle.

A quality custom home theater should be built to last. Sure, the technology is changing quickly—every new year will bring beautiful new home theater projectors to market, especially with the 8K tech about to explode—but choosing a projector from trusted brands and working with a top-notch designer who relies on skilled, talented installers will bring years of unrivaled home theater enjoyment, without the sticky floors or chatty seatmates! That is one of the most important requirements when choosing the right projector.
