XGIMI HORIZON S Max vs BenQ X3100i
XGIMI and BenQ approach premium home projection from different directions. HORIZON S Max is an integrated smart projector with automatic setup and a fixed throw. X3100i is a gaming-focused 4LED projector with optical zoom and vertical lens shift.
The better physical fit depends heavily on where the projector can sit in your room.
| Specification / decision | Option A | Option B |
|---|---|---|
| Resolution | 4K UHD | 4K UHD |
| Brightness | 3100 ISO lumens | 3300 ANSI lumens |
| Light source | Dual Light 2.0 | 4LED |
| Throw ratio | 1.2:1 fixed | 1.15–1.50:1 |
| Optical zoom | No | 1.3x |
| Lens shift | No listed optical lens shift | Vertical 40%–60% |
| Gaming | ≤20 ms game mode (auto keystone off) | 16.7 ms @4K/60; 8.3 ms @1080p/120; 4.2 ms @1080p/240 |
| Smart platform | Android TV 11 | QS02 Android TV dongle |

Do not compare 3100 ISO and 3300 ANSI as one ranking
The brightness numbers use different named standards. Keep the labels attached and avoid concluding that the BenQ is automatically brighter because 3300 is numerically larger than 3100. Screen size and room light also matter.
BenQ has the more flexible lens system
X3100i’s 1.15–1.50 throw range, 1.3x optical zoom and vertical lens shift give a permanent installation more adjustment options. HORIZON S Max uses a fixed 1.2:1 throw with digital zoom and automated geometry tools.
For a 120-inch 16:9 image, XGIMI needs roughly 10.5 feet lens-to-image. BenQ can cover approximately 10.0–13.1 feet across its throw range.
XGIMI reduces setup friction
Automatic focus, screen alignment, obstacle avoidance and an integrated stand make XGIMI convenient when the projector moves or the room changes. BenQ rewards more deliberate placement but gives the installer more optical control.
Gaming favors BenQ’s documented mode table
BenQ publishes latency by resolution and refresh rate, including 16.7 ms at 4K/60 and 4.2 ms at 1080p/240. XGIMI publishes ≤20 ms in game mode with automatic keystone off.
For a PS5-style 4K/60 workflow, both are within the low-tens-of-milliseconds class on their manufacturer specifications. Competitive high-refresh PC use gives BenQ a clearer documented advantage.
Decision shortcut
The XGIMI is easier to treat like a movable smart appliance. The BenQ is easier to treat like a dedicated projector installation.
- Choose XGIMI if fixed 1.2:1 geometry fits and automatic setup is a priority.
- Choose BenQ if optical zoom, lens shift or documented high-refresh gaming modes matter.
- Do not make the decision from the mixed ANSI/ISO brightness numbers alone.
