Hello everyone, I'm your tech guru. Today, we won't talk about empty talk. Let's directly take off the fancy exterior of the projector and examine the core parameters inside to see which ones are really worth your money. The marketing slogans like "cinema-level experience" and "100-inch screen" that are seen in the market today, I'm going to cut through the verbiage and expose their true essence.
- Flaw: The merchant is vigorously promoting "light source lumen 3000" and "brightness 10000", which is pure nonsense and a form of cheating.
- The truth: Identify ANSI lumens, as this is an internationally recognized brightness standard.
- A straightforward conclusion: For nighttime use, 1000 ANSI is the minimum; for the main area of the living room, 1500 ANSI is the starting point; if you want to compete with direct sunlight, 2000 ANSI or above is the threshold.
- Actual test suggestion: Check the actual test results from third-party evaluation agencies instead of believing the promotional materials.
II. Resolution: Native 1080P is always amazing!
-
Weakness: "Compatible with 4K" ≠ "Native 4K". The "jitter 4K" achieved through pixel jittering, although it performs better than 1080P, still has a fundamental difference from the native 4K chip.
- The truth: With a limited budget, stick to the native 1080P (DMD chip size ≥ 0.47 inches), as this is the most cost-effective option. If your budget is sufficient, go for native 4K. Be wary of those 1080P images produced by using a 0.33-inch DMD chip, as their actual physical resolution is actually lower.
III. Contrast: The Soul in a Completely Dark Environment
-
Weakness: The figure of dynamic contrast ratio (several million to 1) is just a number game. Just take a look at it.
- The truth: Focus on FOFO contrast or ANSI contrast. This metric determines whether you can clearly see the details when viewing dark scenes (such as the Battle of Winterfell in "Game of Thrones"), or if everything becomes a blur. Generally, 3LCD technology has an inherent advantage in this regard.
IIV. Intelligent Function: It's an enhancement, not a timely solution.
-
Viewpoint: Features such as auto focus, gradient correction, and intelligent obstacle avoidance have significantly enhanced usability, providing an experience that is "once you use it, you won't want to go back".
- However: Always prioritize the basic image quality (brightness, resolution, contrast). A projector with perfect correction functions but a grayish image is completely upside down.
Remember this formula: High ANSI lumens + Native high resolution + Reliable contrast = The cornerstone of a good projector. Based on this, consider smart functions and audio according to your budget and room conditions. Don't pay for flashy marketing concepts. The parameters won't lie, but the person interpreting them might.
