BenQ W5800 vs W5850: Which One Should You Buy in India?

Key Differences at a Glance

• Lens: the W5800 is long-throw; the W5850 uses an all-new short-throw lens
• Distance for a 200-inch image: about 22 feet versus about 14.5 feet
• Throw ratio: roughly 1.5-2.45 versus 1.0-1.6
• HDMI: 2.0b on the W5800; HDMI 2.1 on the W5850
• The W5850 adds out-of-the-box Dynamic HDR Tone Mapping
• Everything else, laser engine, 2,600 lumens, 100% DCI-P3, calibration, is identical
• Both are the same price

Full Specification Comparison

These are the current BenQ specifications. The picture engine, brightness, colour and calibration are shared; the meaningful differences are the lens and throw distance, plus HDMI version and tone mapping.

Where They Differ in Real Use

The Lens Is the Whole Story

It is rare for two projectors to be this identical in performance and differ only in optics, but that is exactly the case here. Both deliver the same reference picture: the same laser engine, the same 2,600 lumens, the same 100% DCI-P3 colour and the same factory-calibrated accuracy. What changes is how far the projector sits from the screen. The W5800's longer-throw lens suits deeper rooms and rear-of-room mounting, while the W5850's all-new short-throw lens achieves the same big image from much closer, using a more complex 16-element aspheric design to do so without sacrificing sharpness.

Which Fits Your Room

This is the decisive question. If your projector will sit well back from the screen, in a deep, dedicated theatre or mounted near the rear wall, the W5800's throw range is the correct optical match, and pushing a short-throw lens into that distance would oversize the image. If your room is medium-sized or space is tight, as in many apartments, the W5850 is transformative: it can fill a 200-inch screen from around 14.5 feet, where the W5800 would need roughly 22 feet. Measure your intended projector-to-screen distance first; that single number points clearly to one model or the other.

Connectivity and Tone Mapping

Beyond the lens, the W5850 brings two modern touches. It upgrades to HDMI 2.1 (the W5800 uses HDMI 2.0b), and it ships with Dynamic HDR Tone Mapping enabled out of the box, a feature BenQ has said will also reach the W5800 through a firmware update. Neither changes the core image quality, which is essentially identical, but they make the newer W5850 a little more future-facing for high-bandwidth sources.

Value for Money

Because both projectors cost the same and produce the same picture, neither is better value in the abstract; the better value is simply the one whose lens fits your room. For most modern living rooms and apartments with limited depth, the W5850's short throw makes a large screen achievable where the W5800 could not fit, which makes it the more practical choice for many buyers. For deep, dedicated theatres with plenty of throw distance, the W5800 remains a superb and fully current option. Check the table above for current pricing.

Which One Should You Buy?

Choose based on throw distance. For deep rooms and rear-of-room mounting, the BenQ W5800's long-throw lens is the right optical match. For medium-sized rooms and space-limited apartments where you want a big screen from a shorter distance, the BenQ W5850's short-throw lens is the smarter fit, and it adds HDMI 2.1 and out-of-the-box Dynamic HDR Tone Mapping.

Choose the BenQ W5800 if:

• Your room is deep or the projector mounts well back
• Your throw distance suits a longer-throw lens (around 22 feet for 200 inches)
• You want the same reference picture in a proven, current model
• You do not need HDMI 2.1 for your sources

Choose the BenQ W5850 if:

• Your room is medium-sized or space is limited
• You want a large image from a shorter distance (200 inches from ~14.5 feet)
• You want HDMI 2.1 and Dynamic HDR Tone Mapping out of the box
• You want the newest lens design for flexible placement

FAQ

What is the main difference between the BenQ W5800 and W5850?

The lens. Both projectors share the same laser engine, 2,600 lumens, 100% DCI-P3 colour and factory calibration, but the W5800 has a longer-throw lens for deeper rooms, while the W5850 uses a short-throw lens that fills the same 200-inch screen from a much shorter distance. The W5850 also adds HDMI 2.1 and Dynamic HDR Tone Mapping out of the box.

Do the two projectors produce the same picture?

Essentially yes. They use the same light engine, brightness, colour gamut, calibration and HDR support, so image quality is effectively identical. The difference is how far each must sit from the screen to produce that image.

How far does each need to sit for a 200-inch screen?

The W5850 can fill a 200-inch screen from around 14.5 feet thanks to its short-throw lens, while the W5800 needs roughly 22 feet with its longer-throw lens. This is the key factor when choosing between them for your room.

Does the W5850 have HDMI 2.1?

Yes. The W5850 uses HDMI 2.1 with eARC, while the W5800 uses HDMI 2.0b with eARC. Both pass through high-resolution multichannel audio; the newer HDMI on the W5850 offers more headroom for high-bandwidth sources.

Which one is better value?

They cost the same and produce the same picture, so the better value is simply the one whose lens fits your room. The W5850's short throw suits most apartments and medium rooms, while the W5800's longer throw suits deep, dedicated theatres.
