The Ultimate 1LCD Projector Encyclopedia: From Specs to Expert Buying Tips

Are you confused by projector jargon? Between ANSI lumens, native resolution, and throw ratios, choosing the right device can feel overwhelming. At ByteSense, we believe in transparency. This guide is designed to pull back the curtain on projector specifications, helping you choose the perfect setup like a pro.

I. Display Technology: Why 1LCD?

Q1: What is 1LCD, and how does it differ from DLP, 3LCD, or LCoS?

• 1LCD (Single-panel LCD): Uses a single liquid crystal panel. It’s known for true color reproduction, zero "rainbow effect," and incredible value for money.

•  3LCD: Uses three separate panels (RGB). Great color, but bulky and expensive.

• DLP (Digital Light Processing): Uses tiny mirrors. It has high contrast but often suffers from the "rainbow effect" (color strobing) which can cause eye strain.

•  LCoS: A high-end hybrid of LCD and DLP, found in premium home theaters costing thousands of dollars.

Q2: Is it true that 1LCD projectors get "dust spots"?

Traditional 1LCD projectors have an open optical path, meaning dust can enter and settle on the lens, creating permanent black spots. 

ByteSense developed G3/G3S model with our Fully Sealed Optical Engine. By sealing the core components, we eliminate dust entry, 

ensuring a clear image and a significantly longer lifespan.

II. Brightness & Color: Don't Get Fooled by the Numbers

Q3: What is the difference between ANSI, ISO, CVIA, and Lumens?

•  ANSI Lumens: The most universally accepted projection brightness standard with the highest reference value.

•  ISO Lumens: A standard promoted by brands like Epson, similar to ANSI but with stricter testing criteria.

•  CVIA Lumens: China's latest industry standard that takes factors such as color temperature into account, usually with higher numerical values than ANSI.

•  Light Source Lumens: This refers to the brightness of the bulb inside the projector, not the brightness projected onto the wall.

Q4: Deep Dive: Why is Contrast Ratio the "Soul" of the Image?

Contrast is the ratio between the brightest white and the darkest black.

• Static Contrast: The ratio within a single frame (e.g., 1000:1). This is the "real" contrast you see.

• Dynamic Contrast: A marketing number (e.g., 1,000,000:1) achieved by dimming the light source. It doesn't reflect real-world performance.

III. Resolution & Projection: Is it Sharp Enough?

Q5: Is "Native 1080P" the same as "4K Support"?

         No.

• Native Resolution: The actual physical pixels. Native 1080P (1920 *1080) is true High Definition.

• 4K Support: This only means the chip can read a 4K file, but it will still output it in 1080P.

Q6: What is Throw Ratio?

It determines how far the projector needs to be from the wall to hit a certain size.

• Long Throw (1.2:1 and above): Most projectors require approximately 2.7-3 meters to project a 100-inch screen.
• Short Throw (0.6:1 - 1.0:1): For example, ByteSense P2 (0.65:1) only needs about 1.5 meters to project a 100-inch large screen, making it ideal for small bedrooms.
• Ultra Short Throw (below 0.4:1): Usually laser TVs, designed to be placed close to the wall.

IV. Smart Adjustments: Focus & Keystone

Q7: Focus Methods: Manual vs. Electric vs. Auto

• Manual: Turning a ring by hand. Cheap but tedious.

• Electric: Adjusted via remote. Great for precision and edge-to-edge clarity.

• Auto: Uses cameras to focus instantly. Convenient but adds to the cost.

Q8: What is Keystone Correction?

• Vertical Keystone Correction: Adjusts only the vertical direction.
• 4-Point/6-Point Keystone Correction: Allows manual or automatic adjustment of the four corners, supporting side projection.

V. Connectivity & Audio: The Modern Experience

Q9: WiFi 6 vs. WiFi 5?

WiFi 6 offers higher bandwidth and lower latency. If you stream 4K content or play games, WiFi 6 ensures a buffer-free experience.

Q10: Why is "Dolby Audio" a Dealbreaker?

Ever played a movie on Netflix and had no sound? That’s usually because the projector lacks Dolby Decoding.

Most streaming services use Dolby Digital (AC3/E-AC3). 

ByteSense developed G2N model with licensed Dolby Audio hardware decoding, ensuring 100% compatibility and rich, cinematic sound.

VI. Systems: From Basic to Certified

Q11: What is the difference between Android and Certified Google TV (GTV)?

• RTOS / Linux (Lightweight Systems): Only supports screen mirroring, does not allow app downloads. It responds quickly but has limited features.
• AOSP (Open Source Android): Enables app downloads, but Netflix content is usually limited to 480P resolution.
• GTV / Certified Netflix (Officially Licensed): Equipped with genuine Netflix/YouTube, supporting high-definition content playback. It offers the smoothest and most secure system experience.

VII. Accessories: Screens & Casting

Q12: Which Screen should I choose?

• White Fabric: Great for dark rooms; wide viewing angles.

• Fiberglass: Flatter and more durable.

• ALR (Ambient Light Rejection): Reflects overhead light. Essential if you plan to use the projector with the lights on.

Q13: Casting vs. Mirroring

• Casting: You send a link (YouTube/Netflix) to the projector. Your phone is free to use for other things.

• Mirroring: Your projector shows exactly what is on your phone screen. Best for photos or gaming.

Final Pro Tip:

Don't just buy a projector based on the highest numbers. Focus on Sealed Optical Engines for longevity, Native Resolution for clarity, and Dolby Support for compatibility.
