The dilemma of choosing between a television and a projector has long been a topic of debate among many consumers. When it comes to screen size, projectors clearly outshine TVs, offering larger displays in just seconds. Additionally, projectors often boast superior contrast ratios, placing them ahead of TVs in this aspect. However, when we talk about resolution, TVs take the lead. Today, TVs have fully embraced the 4K revolution, with affordable 4K LCD models now priced around 2,000 yuan. No other 4K devices come close to this affordability. Meanwhile, home projectors have been slower to adopt 4K, mostly sticking to 1080p. But there's good news on the horizon—later this year, we’ll see a surge in new 4K home projectors, not only increasing in quantity but also becoming more accessible in terms of pricing. As a result, 4K is set to become the norm for home projectors.
If we look back at the inception of 4K home projectors, Sony’s VPL-VW1000ES was a game-changer. At CES 2012, Sony introduced the world’s first 4K ultra-high-definition 3D home projector, unveiling the potential of 4K projectors to the public and marking the beginning of the high-end home projector's transition into the 4K era. This was similar to the introduction of 4K TVs. It’s remarkable how Sony managed to achieve such groundbreaking innovation, making it a pioneer in the field.
The Sony VPL-VW1000ES features Sony’s proprietary 4K SXRD panel, offering a resolution of 4096×2160, support for 3D functionality, a brightness of 2000 lumens, an ultra-high dynamic contrast ratio of 1,000,000:1, and the ability to project screens larger than 150 inches. Even today, five years later, these specs remain competitive.
Sony’s 4K projection prowess stems from its exclusive development of SXRD technology, an advanced reflective technology first introduced in the QUALIA004 projector in 2003. Subsequent iterations of SXRD projectors have been upgraded to 4K resolution. For instance, the recently released VPL-VW558 boasts 1800 lumens of brightness, a dynamic contrast ratio of up to 350,000:1, and a remarkably long-lasting lamp life of 6000 hours at low power. Features like HDR and wide color gamuts are also becoming standard across Sony’s projector lineup.
Sony’s early investments and extensive development time have allowed it to accumulate deep technical expertise, establishing itself as a benchmark for high-end home projectors and maintaining its leadership in the 4K projector space.
When it comes to the ongoing debate over 4K projection technology, both LCD and DLP camps are vying for dominance. Sony’s SXRD technology, which is an evolution of mainstream 3LCD technology, leads the LCD camp, while Texas Instruments’ DLP technology dominates the DLP camp.
From a technical perspective, LCD projectors emit bright white light that is split into RGB components. These colors are then precisely projected onto the screen through liquid crystals, resulting in vibrant and consistent images. LCD projectors are known for their excellent color reproduction and brightness uniformity.
On the other hand, DLP projectors use Digital Light Processing (DLP) technology, which relies on a digital micromirror device (DMD) developed by Texas Instruments. Light is homogenized and split into RGB colors via a color wheel before being projected onto the DMD chip and ultimately displayed on the screen. DLP projectors are celebrated for their compact size, smooth visuals, and high contrast ratios.
Although DLP 4K projectors entered the market later, Texas Instruments' recent introduction of a DLP 4K display chip has spurred advancements. Brands like Optoma have even brought 4K projectors down to prices below 20,000 yuan, making 4K projectors more accessible to consumers.
In addition to traditional front projectors, ultra-short-throw projectors are gaining traction in the home market due to their convenience. These projectors can be placed like a TV on a cabinet, eliminating the need for extensive wiring. For instance, Sony’s VPL-VZ1000ES, showcased at CES 2017, can project screens ranging from 80 to 120 inches, requiring minimal distance from the wall. It offers electric zoom and focus adjustments, supporting vertical and horizontal adjustments, 3D projection, and HDR compatibility.
If you’re considering purchasing a home projector, prioritizing 4K is advisable, especially given the growing popularity of 4K content. As 4K continues to dominate the market, investing in a 4K projector ensures longevity and future-proofing your viewing experience.
