Projectors have become increasingly popular thanks to technological advancements, offering crisp image quality, high brightness, and affordability. Modern projectors are compact, portable, and versatile, allowing connections to various devices such as computers, phones, or gaming consoles.
Beyond their traditional use in offices and schools, projectors are also gaining traction in home entertainment, delivering impressive viewing experiences with large and flexible images. Their portability and versatility make them a popular choice for diverse needs, with many families opting for projectors instead of televisions.
I also chose to set up a projector at home instead of buying a TV, but I wasn’t sure how to make the right choice. It took me three tries to realize that buying a projector should follow these eight rules:
1. Opt for a projector with a 1080p resolution
When it comes to resolution, 1080p is the sweet spot and the most common standard that meets most users’ needs. If your budget allows, consider a 4K projector for even sharper images.
However, it’s worth noting that finding a quality 4K projector under $10,000,000 VND is challenging. So, for this price range, a 1080p projector is more than sufficient.
2. Choose a projector with a 0.47DMD chip size
For 1080p resolution, the ideal chip size is 0.47DMD. If you come across a 4K projector with the same chip size, it may be using a shaking technique to achieve that resolution, but this won’t affect your viewing experience.
On the other hand, avoid projectors with a 1080p resolution paired with smaller chip sizes like 0.23DMD or 0.33DMD, as they won’t perform optimally.
3. Pay attention to brightness
Lumens are the standard measure of light intensity for projectors, and there are three types: ANSI lumens, CVIA lumens, and ISO lumens. For the best image quality, look for a projector with ANSI lumens above 3,000, CVIA lumens above 1,800, and ISO lumens above 2,500.
4. Steer clear of single-panel LCD technology
Among the available display technologies, DLP (Digital Light Processing) is the top choice thanks to its high contrast ratios and vibrant colors. Alternatively, you can consider 3LCD (three-panel LCD), although it tends to be more expensive.
The advantage of 3LCD is its ability to reproduce natural colors and deliver bright images. On the other hand, single-panel LCD technology is not recommended.
5. Avoid side projection
There are two projection methods: front projection and side projection. Front projection is the recommended method, as it provides stable and clearer images, and makes alignment more accurate since the projector faces the screen directly.
Side projection, on the other hand, can affect image accuracy and brightness. Additionally, aim for an aspect ratio between 1.2:1 and 1.3:1 for optimal results.
6. Go for projectors with Dolby Audio technology
When choosing audio equipment for your projector, prioritize those with Dolby Audio technology. This renowned surround sound technology enhances audio realism. In contrast, while HiFi stereo offers high fidelity, it can’t match the cinematic audio experience provided by Dolby Audio.
7. Opt for laser-based projectors
When selecting a projector, consider those that use LED or laser light sources. Although they produce similar image effects, laser projectors tend to deliver sharper images than LED projectors during the day.
Traditional lamp-based projectors, on the other hand, require periodic bulb replacements to maintain image quality. Laser projectors provide continuous lighting and superior color accuracy.
8. Choose a projector with automatic keystone correction
Look for a projector with automatic keystone correction, which adjusts trapezoidal distortions for more geometrically accurate images. Avoid projectors with only vertical correction, as they restrict adjustments to up and down movements, making usage more complicated and less effective.
