ViewSonic PX749-4K vs PX701-4K: PX749 allows a closer mount and gives more zoom freedom

Quick verdict

If a 1.5 to 1.65 throw fits your room and price matters most, the PX701-4K is the right pick. The PX749-4K is for when the projector has to sit closer, some lights stay on, or the extra zoom range gets an existing mount to work.

Before you buy

Why, and what it costs you

Published ANSI brightness: how big the gap is

The published “ANSI brightness” figure is 25% higher on ViewSonic PX749-4K: 4,000 ANSI lumens, against 3,200 ANSI lumens on ViewSonic PX701-4K.

Where this comes from

Higher published output is useful only if your room, surface or workload calls for the extra headroom. It does not, by itself, prove better results. The percentage comes from the lower published figure.

The catch

ViewSonic PX701-4K

No smart platform, and the light is a replaceable lamp.

The catch

ViewSonic PX749-4K

What this page compares

A long-throw gaming model meets a brighter alternative that focuses closer and has more optical zoom.

This one comes down to published ansi brightness and throw ratio first, then to the limits of your own setup.

Which one fits

Pick the situations that sound like you

  • I will keep some lights on while I watch

    Moderate room light is a better match for its documented light output. A suitable screen and controlled daylight still matter.

  • I cannot move the position of my shelf or ceiling mount

    ViewSonic PX701-4K lists “1.1x” for optical zoom, while ViewSonic PX749-4K lists “1.3x”. This affects image compatibility, placement or picture quality. Compare matching standards before you call either label the winner.

  • Published ANSI brightness is non-negotiable

    ViewSonic PX701-4K lists “3,200 ANSI lumens” for published ansi brightness, while ViewSonic PX749-4K lists “4,000 ANSI lumens”. Extra published output only helps when your room, surface or workload needs the headroom. On its own, it does not prove better results.

  • Throw ratio is non-negotiable

    ViewSonic PX701-4K lists “1.5–1.65:1” for throw ratio, while ViewSonic PX749-4K lists “1.13–1.47:1”. Measure your space and mounting points first. This can be a hard limit on fit.

Where these two really part ways

ViewSonic PX749-4K is the better match for “I will keep some lights on while I watch” and “I cannot move the position of my shelf or ceiling mount”.

How we worked this out

This lines up the current strong and useful fit ratings for the exact products. It does not roll them into one overall score.

One of them covers more of your list

ViewSonic PX749-4K meets 3 of the 3 needs this comparison is built around. ViewSonic PX701-4K meets 2 and misses “I cannot move the position of my shelf or ceiling mount”.

Trade-offs

What each pick costs you

With ViewSonic PX701-4K

  • A fixed shelf or mount position can't be corrected much with a 1.1x zoom.

With ViewSonic PX749-4K

  • The lens zooms optically but doesn't have true lens shift, and there is no smart OS.
