Main trade-off
BenQ W4100i
Its shorter maximum throw and manual lens controls can be awkward in a deep fixed theater.
Head-to-head
BenQ W4100i vs Epson Home Cinema 5050UB: BenQ fits closer, Epson changes its lens from the seat
The short answer
Choose W4100i for a shorter room, an included streaming device and an LED light source without scheduled lamp replacements. Choose 5050UB for a deeper theater needing powered lens changes or a viewer sensitive to single-chip DLP rainbows. The lens workflow is often the deciding difference.
Before you choose
The reasoning and the trade-offs
A 10.5-foot shelf and an eighteen-foot shelf produce opposite answers
For a 120-inch 16:9 picture, W4100i covers about 10.0 to 13.1 feet from lens to screen. Epson covers about 11.8 to 24.8 feet. At 10.5 feet, BenQ is the candidate. At eighteen feet, Epson is. Check exact tolerances before fixing a mount at a range endpoint.
What this is based on
BenQ W4100i: Throw ratio 1.15 to 1.50. Epson Home Cinema 5050UB: Throw ratio 1.35 to 2.84. Lens distance = 104.59-inch picture width × throw ratio.

What matters in practice
The differences that matter
A 10.5-foot shelf and an eighteen-foot shelf produce opposite answers
For a 120-inch 16:9 picture, W4100i covers about 10.0 to 13.1 feet from lens to screen. Epson covers about 11.8 to 24.8 feet. At 10.5 feet, BenQ is the candidate. At eighteen feet, Epson is. Check exact tolerances before fixing a mount at a range endpoint.
How we reached this conclusion
BenQ W4100i: Throw ratio 1.15 to 1.50. Epson Home Cinema 5050UB: Throw ratio 1.35 to 2.84. Lens distance = 104.59-inch picture width × throw ratio.
Several sources need not displace the included streamer
W4100i’s QS02 uses its internal connection, leaving three external HDMI inputs. With one external eARC connection and two external video sources, the published port layout can accommodate that simple arrangement. An existing AV receiver reduces the importance of this advantage.
How we reached this conclusion
BenQ W4100i: Three external HDMI inputs, internal QS02 connection and eARC on HDMI 2. Epson Home Cinema 5050UB: External source and sound system required. No included streamer is assumed.
A high inaccessible mount makes maintenance and lens controls pull apart
BenQ’s LED source avoids the replaceable-lamp task, while Epson’s powered lens avoids reaching the projector for lens adjustment. If you rarely change formats, BenQ’s lower lamp-maintenance burden may matter more. Frequent image-position changes give Epson’s powered controls more value.
How we reached this conclusion
BenQ W4100i: LED light source and manual optical adjustment. Epson Home Cinema 5050UB: Replaceable lamp and powered zoom, focus and shift. No service interval or cost saving invented.

Meaningful differences
What changes the fit
| What changes | BenQ W4100i | Epson Home Cinema 5050UB | Why it matters |
|---|---|---|---|
| Optical throw range | 1.15 to 1.50 | 1.35 to 2.84 | A fixed shelf can rule out one before picture preferences enter the decision. |
| Light source | 4LED | Replaceable lamp | Long-term maintenance is different, without enough data here to price lifetime ownership. |
| Lens controls | Manual optical adjustment with horizontal and vertical shift | Powered zoom, focus and horizontal and vertical shift | Changing the picture position repeatedly favors motorized controls. |
| Streaming and inputs | Included QS02 device, three external HDMI inputs | External sources required | Count boxes and cables for the actual theater. |
| Imaging | Single-chip DLP | Three-chip 3LCD | Epson avoids the DLP color-sequencing mechanism. |
What you give up
Every choice has a cost
If you choose BenQ W4100i
- HDMI 3 accepts 4K/120 input but displays it at 1080p/120. It is not a 4K/120 projector.
If you choose Epson Home Cinema 5050UB
- There is no smart platform, built-in audio or high-refresh 4K gaming support.
Recommendation switch
The decision flips if...
A 120-inch picture must fit from 10.5 feet
Choose BenQ W4100i. You want included streaming and several external HDMI sources
A deep room needs a rear shelf beyond thirteen feet
Choose Epson Home Cinema 5050UB. Powered lens adjustment is valuable for the installation
