When choosing a projector, it's easy to feel overwhelmed due to the wide variety of models and features available on the market. Each projector comes with different specifications, and selecting the right one based on your specific needs is essential. Below are some helpful tips to guide you in making an informed decision.
(1) **Portability** – If you plan to use the projector frequently outside of your office, such as for presentations on the go, portability becomes a key factor. A lightweight and compact design will make it easier to carry and set up in different locations.
(2) **Scan Range** – Check the horizontal scan frequency range specified in the technical specs. Test the projector at high, medium, and low frequencies to ensure it can display images clearly at those resolutions. Poor scan tracking may result in distorted or flickering images.
(3) **Focus Performance** – Use a test pattern from the projector or a computer to adjust the focus. Ensure that the lines on the test image remain sharp and do not blur or spread out when adjusting contrast. A good focusing system ensures clear and precise visuals.
(4) **Video Bandwidth** – Video bandwidth determines how well the projector handles fine details. Test it by displaying small text or intricate graphics. If the image appears blurry or lacks clarity, the video bandwidth may be insufficient.
(5) **Image Quality** – High-quality image output is crucial. A good projector should produce deep blacks, accurate colors, and sharp text. This is especially important when displaying detailed content like hair or fine textures.
(6) **Installation Method** – Consider the installation type: front projection (projector placed in front of the screen), rear projection (projector behind the screen), or ceiling mounting. For temporary use, front projection is convenient, while ceiling mounting is ideal for permanent setups.
(7) **Resolution** – The resolution of your projector should match the output of your computer or other devices. While SVGA is sufficient for most general uses, higher resolutions like XGA or WXGA may be necessary for more demanding applications.
(8) **Brightness** – Brightness is measured in lumens. For small rooms (15–30 sq.m), 2500 lumens is usually enough. In larger spaces (30–60 sq.m), 3000–3500 lumens is recommended. For very large areas, 4000 lumens or more is ideal.
(9) **Lamp Life** – Projector lamps are consumables and vary in lifespan and cost. Common types include metal halide, UHE, and UHP bulbs. UHE bulbs offer good value, while UHP bulbs are used in high-end models for better performance.
(10) **Brand Choice** – Popular brands like Sony, BenQ, Epson, and others are known for their reliability and quality. Choosing a trusted brand ensures better support and long-term performance.
