Head-to-head

BenQ TK710 vs ViewSonic PX749-4K: BenQ adds vertical shift without changing the room class

The short answer

Choose TK710 for a laser light source and vertical lens shift. PX749-4K suits a lamp-based gaming setup with a closely similar throw range.

Before you choose

The reasoning and the trade-offs

Fit a 120-inch picture before choosing

BenQ TK710 needs 10 to 13.1 ft from lens to screen for a 120-inch 16:9 picture. ViewSonic PX749-4K needs 9.8 to 12.8 ft.

What this is based on

Width = diagonal × 16 / √337. At 120 inches the width is 104.6 inches. Multiply by each documented throw endpoint and divide by 12 for feet. This excludes digital zoom, keystone, cabinet offset and lens-shift limits.

Main trade-off

BenQ TK710

Its color coverage tops out around Rec.709 rather than the wider cinema gamuts of premium RGB-laser models.

Main trade-off

ViewSonic PX749-4K

It uses a replaceable lamp instead of a solid-state light source.

About this comparison

Choose TK710 for a laser light source and vertical lens shift. PX749-4K suits a lamp-based gaming setup with a closely similar throw range.

The room-fit difference is small

Winner by situation

Start with what you need it to do

  • Avoid lamp replacements in regular use

    TK710 uses a laser light source and PX749-4K uses a replaceable lamp. Frequent use gives the lamp-maintenance difference more weight than their largely overlapping throw ranges.

  • The lamp-based setup fits the budget

    TK710 uses a laser and PX749 a lamp. The maintenance choice can outweigh a brightness headline for a projector used several evenings a week.

  • I have chosen a 120-inch 16:9 screen

    Use 10 to 13.1 ft for BenQ TK710 or 9.8 to 12.8 ft for ViewSonic PX749-4K, measured from the lens. Check the cabinet and mounting clearances separately.

What matters in practice

The differences that matter

Fit a 120-inch picture before choosing

BenQ TK710 needs 10 to 13.1 ft from lens to screen for a 120-inch 16:9 picture. ViewSonic PX749-4K needs 9.8 to 12.8 ft.

How we reached this conclusion

Width = diagonal × 16 / √337. At 120 inches the width is 104.6 inches. Multiply by each documented throw endpoint and divide by 12 for feet. This excludes digital zoom, keystone, cabinet offset and lens-shift limits.

Read the light ratings with their limits

BenQ TK710 lists 3200 ANSI lumens and ViewSonic PX749-4K 4000. The higher headline is about 25% above the lower one. These are manufacturer ratings, not matched measurements.

How we reached this conclusion

Exact published inputs are 3200 ANSI for BenQ TK710 and 4000 ANSI for ViewSonic PX749-4K. A percentage is shown only within the same labeled standard. Manufacturer methods, calibration and picture modes can still differ.

A similar mount can hide a different maintenance purchase

TK710 and PX749-4K have closely overlapping throw ranges, but only TK710 uses a laser light source and offers vertical lens shift in this pair.

How we reached this conclusion

BenQ documents laser, +10% vertical shift and 1.15 to 1.5 throw. ViewSonic PX749-4K is lamp-based with 1.13 to 1.47 throw.

Try your real numbers

Will either projector fit your room?

The result checks hard limits only. Preferences stay out of the calculation.

BenQ TK710

Does not fit these inputs

For a 120-inch 16:9 picture, the calculated lens range is about 10.02 to 13.07 ft. Your input is 9.50 ft.

ViewSonic PX749-4K

Does not fit these inputs

For a 120-inch 16:9 picture, the calculated lens range is about 9.85 to 12.81 ft. Your input is 9.50 ft.

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.

What you give up

Every choice has a cost

If you choose BenQ TK710

  • It lacks a built-in smart platform, and independent testing found only average black levels and imperfect out-of-box color.

If you choose ViewSonic PX749-4K

  • There is no smart OS, and the lens has optical zoom but no true lens shift.

What matters in practice

How to make the call

01

The room-fit difference is small

Throw ranges are 1.15 to 1.5 for BenQ and 1.13 to 1.47 for ViewSonic. Most ordinary positions inside the overlap should not force the decision.

02

Light-source upkeep matters over years

TK710 uses a laser and PX749 a lamp. The maintenance choice can outweigh a brightness headline for a projector used several evenings a week.

03

High-refresh compatibility needs the resolution too

ViewSonic documents 1440p120 support. BenQ lists 2K120 downscaled to 1080p, so confirm which output mode is important before treating both as equivalent gaming choices.

Check these before buying

  • Measure the image width and the distance from the lens, not from the back of the projector.
  • Confirm the exact US model, included streamer and power accessories on Amazon.

What this comparison cannot tell you

  • Throw calculations use published optical ranges and a 16:9 picture. They are not a substitute for the exact installation diagram.
  • Published lumens, contrast and latency do not establish a matched real-room picture-quality result.
