BenQ W2710i vs W4000i: Which One Should You Buy in India?

Key Differences at a Glance

• Light source: W2710i is lamp-based; W4000i uses a long-life 4LED source (20,000 hours)
• Brightness: 2,200 ANSI lumens versus 3,200 ANSI lumens
• DMD chip: 0.47-inch on the W2710i; a larger 0.65-inch on the W4000i
• Colour: 95% DCI-P3 versus 100% DCI-P3
• Contrast: 50,000:1 versus 2,000,000:1 dynamic
• Lens shift: vertical-only on the W2710i; vertical and horizontal on the W4000i
• Both are True 4K DLP with Android TV, HDR-PRO and factory calibration

Full Specification Comparison

These are the current BenQ specifications. The 4K DLP engine, Android TV, HDR-PRO processing and factory calibration are shared; the W4000i's advantages are its LED light source, brightness, larger DMD, wider colour, higher contrast and more flexible installation.

Where They Differ in Real Use

Light Source: Lamp vs LED

This is the defining difference. The W2710i uses a traditional lamp, which delivers excellent images but has a finite life (rated up to 15,000 hours in its most economical mode) and will eventually need replacing, with brightness and colour gradually shifting over time. The W4000i uses a 4LED light source rated at 20,000 hours, with instant on and off, no lamp to replace, and far more consistent colour and brightness across its life. For anyone who watches often or wants a fit-and-forget projector, the LED engine is a genuine long-term advantage.

Brightness, DMD and Picture

The W4000i is both brighter and built on a larger 0.65-inch DMD compared with the W2710i's 0.47-inch chip, and it widens colour coverage to a full 100% DCI-P3 against the W2710i's 95%. Combined with far higher dynamic contrast, the W4000i produces a punchier, more saturated and more room-tolerant image, better suited to spaces with some ambient light. The W2710i remains a superb performer in a dark room, where its contrast and HDR-PRO processing shine, but the W4000i has more headroom and pop.

Installation Flexibility

The W4000i is much easier to place. It offers both vertical (0-60%) and horizontal (±15%) lens shift, so it can be positioned off-centre and still fill the screen cleanly. The W2710i provides a more limited vertical-only lens shift, which means it needs to be lined up more carefully with the screen. If your room forces an off-axis or shelf placement, the W4000i's lens shift makes setup far less fiddly.

Value for Money

The W2710i is the value champion: it delivers true 4K, HDR-PRO, factory-calibrated 95% DCI-P3 colour and even HDR10+ support at a much lower price, and in a dedicated dark room it gets you most of the cinematic experience for less. The W4000i, as the considerably higher-priced model, justifies its premium through the LED light source, extra brightness, wider colour, larger DMD, higher contrast and flexible installation. If you have a dark room and a tighter budget, the W2710i is the smart buy; if you want the brighter, lower-maintenance, more flexible reference option, the W4000i is worth the step up.

Which One Should You Buy?

For dedicated dark rooms and buyers who want reference 4K HDR at the best price, the BenQ W2710i is the smart pick. For a brighter, wider-colour, LED-lit projector with no lamp maintenance and flexible installation, the BenQ W4000i is the stronger choice.

Choose the BenQ W2710i if:

• You have a dedicated dark room for movie viewing
• You want true 4K, HDR-PRO and factory calibration at the best value
• You can line the projector up fairly centrally with the screen
• HDR10+ support matters to your sources

Choose the BenQ W4000i if:

• You want a long-life 4LED light source with no lamp maintenance
• You want more brightness and full 100% DCI-P3 colour
• You need flexible vertical and horizontal lens shift for placement
• You want the larger 0.65-inch DMD and higher dynamic contrast

FAQ

What is the main difference between the BenQ W2710i and W4000i?

The light source and class. The W2710i is a lamp-based 4K projector with 2,200 ANSI lumens and a 0.47-inch DMD, while the W4000i uses a long-life 4LED light source with 3,200 ANSI lumens, a larger 0.65-inch DMD, 100% DCI-P3 colour and far more flexible lens shift.

Does the W4000i need lamp replacements?

No. The W4000i uses a 4LED light source rated at around 20,000 hours with instant on and off and no lamp to replace, offering more consistent colour and brightness over time. The W2710i uses a lamp, which has a finite life and will eventually need replacing.

Which BenQ projector is better for a room with some ambient light?

The W4000i. Its higher 3,200-lumen brightness, larger DMD and wider colour make it more tolerant of ambient light. The W2710i is at its best in a dedicated dark room, where its contrast and HDR-PRO processing deliver an excellent cinematic image.

Is the W2710i easy to install anywhere?

It needs more careful placement. The W2710i offers vertical-only lens shift, so it should be lined up fairly centrally with the screen. The W4000i adds horizontal lens shift as well, making off-centre and shelf placements much easier.

Which BenQ projector is better value?

The W2710i is the stronger value, delivering true 4K, HDR-PRO, factory-calibrated colour and HDR10+ at a much lower price, ideal for dark rooms. The W4000i costs more and is worth it for its LED light source, extra brightness, wider colour and flexible installation.
