The catch
BenQ TK710
Premium RGB-laser models cover the wider cinema gamuts, while this model's color coverage peaks at roughly Rec.709.
Side by side
BenQ TK710 vs ViewSonic PX749-4K compared: BenQ brings vertical shift and leaves the room class as it is
Quick verdict
Pick the TK710 if you want a laser light source and vertical lens shift. The PX749-4K fits a lamp-based gaming setup, and its throw range is closely similar.
Before you buy
Why, and what it costs you
Confirm a 120-inch picture fits first
With the BenQ TK710, a 120-inch 16:9 picture needs 10 to 13.1 ft from lens to screen. With the ViewSonic PX749-4K it needs 9.8 to 12.8 ft.
Where this comes from
Width = diagonal × 16 / √337, which is 104.6 inches at 120 inches. Times each documented throw endpoint, divided by 12, that gives feet. Digital zoom, keystone, cabinet offset and lens-shift limits are not included.
The catch
ViewSonic PX749-4K
A replaceable lamp provides the light. There is no solid-state source.

Pick the situations that sound like you
Regular use, minus lamp replacements
A laser light source powers the TK710, while the PX749-4K uses a replaceable lamp. With frequent use, that lamp-maintenance difference counts for more than the throw ranges, which largely overlap.
- BenQ TK710
- Better fit
- ViewSonic PX749-4K

A lamp-based setup suits the budget
A laser powers the TK710 and a lamp the PX749. For a projector used several evenings a week, that maintenance choice can outweigh a brightness headline.

Measuring from the lens, plan on 10 to 13.1 ft for the BenQ TK710 or 9.8 to 12.8 ft for the ViewSonic PX749-4K. Cabinet and mounting clearances should be checked separately.

I don't want to buy the wrong edition for streaming
The documented platform for the BenQ TK710 is None, and so it is for the ViewSonic PX749-4K. Verify the exact US model and the apps you need, rather than a similar name or older generation.

In practice
Differences you will notice
Confirm a 120-inch picture fits first
With the BenQ TK710, a 120-inch 16:9 picture needs 10 to 13.1 ft from lens to screen. With the ViewSonic PX749-4K it needs 9.8 to 12.8 ft.
How we worked this out
Width = diagonal × 16 / √337, which is 104.6 inches at 120 inches. Times each documented throw endpoint, divided by 12, that gives feet. Digital zoom, keystone, cabinet offset and lens-shift limits are not included.
Treat the light ratings with their limits in mind
The BenQ TK710 is listed at 3200 ANSI lumens and the ViewSonic PX749-4K at 4000. That puts the higher headline about 25% above the lower one, though both are manufacturer ratings and not matched measurements.
How we worked this out
The exact inputs are 3200 ANSI for BenQ TK710 and 4000 ANSI for ViewSonic PX749-4K, as published. A percentage is shown only within a single labeled standard. Manufacturer methods, calibration and picture modes can still differ.
Similar mounts, different maintenance purchases
The throw ranges of the TK710 and PX749-4K overlap closely. In this pair, though, only the TK710 has a laser light source and vertical lens shift.
How we worked this out
Laser, +10% vertical shift and a 1.15 to 1.5 throw are what BenQ documents. The ViewSonic PX749-4K is lamp-based, with a 1.13 to 1.47 throw.

Spec by spec
Where they really differ
| Spec | BenQ TK710 | ViewSonic PX749-4K | In practice |
|---|---|---|---|
| Optical throw ratio | 1.15 to 1.5 | 1.13 to 1.47 | Distance runs from the lens to the screen and is calculated from the image width. |
| Lens distance for 120 inches | 10 to 13.1 ft | 9.8 to 12.8 ft | The calculation assumes 16:9 and optical adjustment alone. Cabinet depth and cable clearance come on top. |
| Published image-size range | 30 to 300 in | 30 to 300 in | A supported maximum is no guarantee of a bright picture in your room. |
| Published light output | 3200 ANSI lumens | 4000 ANSI lumens | You cannot swap one measurement standard or picture mode for another. |
| Display architecture | single-chip-dlp | single-chip-dlp | Viewers who are sensitive to rainbow flashes may care about single-chip sequential color. |
| Streaming platform | None | None | Before you add a separate streamer, confirm the exact US edition and the apps you need. |
Trade-offs
What each pick costs you
With BenQ TK710
- No smart platform is built in. Independent testing also found black levels that were merely average and out-of-box color that wasn't perfect.
With ViewSonic PX749-4K
- The lens zooms optically but doesn't have true lens shift, and there is no smart OS.
Decision guide
How to decide
TK710 is for a laser light source and vertical lens shift. PX749-4K is for a lamp-based gaming setup with a closely similar throw range.
The gap in room fit is small
BenQ's throw range is 1.15 to 1.5 and ViewSonic's is 1.13 to 1.47. For most ordinary positions inside the overlap, the decision shouldn't hinge on this.
Light-source upkeep adds up over the years
A laser powers the TK710 and a lamp the PX749. For a projector used several evenings a week, that maintenance choice can outweigh a brightness headline.
High-refresh compatibility depends on resolution as well
1440p120 support is documented by ViewSonic, while BenQ lists 2K120 downscaled to 1080p. Confirm which output mode matters to you before treating both as equivalent gaming choices.
What this page can’t tell you
- These throw calculations take published optical ranges and a 16:9 picture as given, and they can't replace the exact installation diagram.
- Published lumens, contrast and latency stop short of establishing a matched real-room picture-quality result.
