Main trade-off
BenQ TK710
It does not provide horizontal lens shift for an off-center shelf.
Head-to-head
BenQ TK710 vs Epson Home Cinema 3800: BenQ fits closer, Epson shifts sideways from a rear mount
The short answer
Choose TK710 when a shorter lens-to-screen distance or high-refresh 1080p gaming defines the room. Choose Home Cinema 3800 when the projector must sit farther back or needs horizontal lens shift. Both need a realistic light-control plan for films. Their headline brightness figures do not tell you which produces the better calibrated picture in your room.
Before you choose
The reasoning and the trade-offs
The fixed shelf can choose the projector before brightness does
For a 120-inch 16:9 image, the screen is about 2.66m wide. TK710's optical range puts the lens around 3.05 to 3.98m away.
What this is based on
Width = 120 × 16 / √337 × 0.0254 = 2.6566m. Multiply by the documented throw endpoints. Distances are lens-to-screen, not cabinet-to-wall.
Main trade-off
Epson Home Cinema 3800
It cannot fill the stated 120-inch image from a 3.2m lens position.

- It does not provide horizontal lens shift for an off-center shelf.
Epson Home Cinema 3800
- Choose it for
- Keep a 120-inch screen with a lens position around 5.2m

About this comparison
Compare BenQ TK710 and Epson 3800 for a fixed shelf, a 120-inch screen, off-center installation and a console in a light-controlled room.
Choose TK710 when a shorter lens-to-screen distance or high-refresh 1080p gaming defines the room. Choose Home Cinema 3800 when the projector must sit farther back or needs horizontal lens shift. Both need a realistic light-control plan for films. Their headline brightness figures do not tell you which produces the better calibrated picture in your room.

What matters in practice
The differences that matter
The fixed shelf can choose the projector before brightness does
For a 120-inch 16:9 image, the screen is about 2.66m wide. TK710's optical range puts the lens around 3.05 to 3.98m away.
How we reached this conclusion
Width = 120 × 16 / √337 × 0.0254 = 2.6566m. Multiply by the documented throw endpoints. Distances are lens-to-screen, not cabinet-to-wall.
An off-center shelf needs optical adjustment, not a brighter mode
If furniture forces the projector to one side, Epson's horizontal lens shift can preserve a square image without relying on angled placement. TK710's vertical adjustment does not supply horizontal shift.
How we reached this conclusion
Epson provides horizontal and vertical optical shift. TK710's documented lens shift is vertical. Maximum shift extremes must not be assumed simultaneously available.
High refresh trades away 4K in this pair
TK710's 1080p240 timing is useful only when the source can supply that mode. For a console running 4K60, the high-refresh number alone does not distinguish the supported signal path.
How we reached this conclusion
TK710 documents 4K60 and 1080p240. Epson documents 4K60 input.

The result checks hard limits only. Preferences stay out of the calculation.
BenQ TK710
Does not fit these inputsFor a 120-inch 16:9 picture, the calculated lens range is about 10.02 to 13.07 ft. Your input is 9.50 ft.
Epson Home Cinema 3800
Does not fit these inputsFor a 120-inch 16:9 picture, the calculated lens range is about 11.50 to 18.74 ft. Your input is 9.50 ft. Optical estimate only: rounded throw ratios do not replace the manual’s 16:9 placement table. Check optical zoom, combined lens-shift limits, body/cables and ventilation before mounting. Digital correction adds no optical range.
Distance is measured from the lens to the screen. The calculation uses a 16:9 image and the verified optical throw range for each exact model.

Meaningful differences
What changes the fit
| What changes | BenQ TK710 | Epson Home Cinema 3800 | Why it matters |
|---|---|---|---|
| Optical throw range | 1.15 to 1.50 | 1.32 to 2.15 | The same screen size needs different physical lens positions. |
| Lens shift | Vertical adjustment | Vertical and horizontal adjustment | Horizontal shift can matter when the shelf cannot sit on the screen centerline. |
| Light source | Laser | Replaceable lamp | Their ownership and service plans differ without establishing a picture-quality winner. |
| Supported gaming input | 4K60 or up to 1080p240 | 4K60 input | TK710's high-refresh option requires a compatible lower-resolution source. |
What you give up
Every choice has a cost
If you choose BenQ TK710
- Its 240Hz mode is 1080p rather than 4K.
If you choose Epson Home Cinema 3800
- Lamp replacement belongs in the ownership plan.
Recommendation switch
The decision flips if...
My 120-inch screen must work from a 3.2m lens position
Choose BenQ TK710. That distance falls inside TK710's optical range.
My shelf is around 5.2m back or needs horizontal lens shift
Choose Epson Home Cinema 3800. Epson provides the longer throw range and horizontal optical adjustment.
What matters in practice
How to make the call
Choose TK710 when a shorter lens-to-screen distance or high-refresh 1080p gaming defines the room.
The fixed shelf can choose the projector before brightness does
For a 120-inch 16:9 image, the screen is about 2.66m wide. TK710's optical range puts the lens around 3.05 to 3.98m away. Epson 3800 needs about 3.51 to 5.71m. A fixed 3.2m lens position favors TK710, while a 5.2m rear shelf favors Epson. Choose the model that fits the actual lens position, then check chassis clearance and the screen's height.
An off-center shelf needs optical adjustment, not a brighter mode
If furniture forces the projector to one side, Epson's horizontal lens shift can preserve a square image without relying on angled placement. TK710's vertical adjustment does not supply horizontal shift. Choose Epson when that lateral placement requirement fits its documented adjustment envelope. Choose TK710 when you can center it and prefer its source options. Epson's maximum horizontal and vertical shift are separate limits, so check their combined-position diagram before mounting.
