The catch
Dangbei Atom
The gimbal stand is optional and costs extra, and there's no battery.
Side by side
BenQ GV50 vs Dangbei Atom: GV50 has a battery and ceiling stand, Atom needs power
Quick verdict
For a slim plugged-in projector, go with the Atom. If an internal battery and a ceiling-friendly stand are essential, the GV50 is the better fit.
Before you buy
Why, and what it costs you
Confirm a 120-inch picture fits first
In a 120-inch 16:9 setup, the Dangbei Atom needs 10.5 ft from lens to screen, and the BenQ GV50 needs 10.5 ft as well.
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
BenQ GV50
Even with a 4K source, the native image stays 1080p. With a 500 ANSI-lumen spec, plan on controlling room light.

What this page compares
Atom is the choice for a slim plugged-in projector, and GV50 fits better when an internal battery and ceiling-friendly stand are essential.

Which one fits
Pick the situations that sound like you
You care about a slim cabinet on the shelf
On a shelf, the advantage of the Atom is its slim cabinet. A thinner body does not shorten the lens distance, though, since both need the same fixed 1.2 throw.

An internal battery is on your list
Whether the projector can run without an outlet or separate power supply comes down to this. The GV50 has an internal battery, and the Atom needs external power.

From the lens, allow 10.5 ft for the Dangbei Atom and 10.5 ft for the BenQ GV50. Cabinet and mounting clearances get checked separately.

The Dangbei Atom and the BenQ GV50 are both documented with Google TV. Confirm the exact US model and the apps you need, rather than relying on a similar name or older generation.

In practice
Differences you will notice
Confirm a 120-inch picture fits first
In a 120-inch 16:9 setup, the Dangbei Atom needs 10.5 ft from lens to screen, and the BenQ GV50 needs 10.5 ft as well.
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 Dangbei Atom is listed at 1200 ISO lumens and the BenQ GV50 at 500 ANSI. Those are different labeled standards, so they are not turned into a brightness multiplier.
How we worked this out
The published inputs, exactly, are 1200 ISO for Dangbei Atom and 500 ANSI for BenQ GV50. Percentages are only shown within the same labeled standard. Manufacturer methods, calibration and picture modes can still differ.
A slim body is no stand-in for a battery or a ceiling stand
Both the Atom and the GV50 have a fixed 1.2 throw. For a self-contained bedside setup, only the GV50 supplies the documented internal battery and rotating stand.
How we worked this out
A fixed 1.2 throw is specified in both records. The Atom needs external power, while the GV50 includes a battery plus a 360-degree base with 135-degree vertical adjustment.
Plug in your numbers

This checks hard limits only. Personal preferences are left out of the math.

Does not work with your numbersFor a 120-inch 16:9 picture, the calculated lens position is about 10.46 ft. You entered 9.50 ft.

Measure distance from the lens to the screen. The math assumes a 16:9 picture and uses the verified throw range for each exact model.

Spec by spec
Where they really differ
| Spec | Dangbei Atom | BenQ GV50 | In practice |
|---|---|---|---|
| Optical throw ratio | 1.2 to 1.2 | 1.2 to 1.2 | Distance runs from the lens to the screen and is calculated from the image width. |
| Lens distance for 120 inches | 10.5 ft | 10.5 ft | The calculation assumes 16:9 and optical adjustment alone. Cabinet depth and cable clearance come on top. |
| Published image-size range | 40 to 180 in | 30 to 120 in | A supported maximum is no guarantee of a bright picture in your room. |
| Published light output | 1200 ISO lumens | 500 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 | Google TV | Google TV | Before you add a separate streamer, confirm the exact US edition and the apps you need. |
Trade-offs
What each pick costs you
With Dangbei Atom
- Neither detail nor placement matches 4K optical-zoom models, given the 1080p image and fixed throw.
With BenQ GV50
- Running on battery can lower brightness, and with no optical zoom you can't resize the picture from a fixed position.
Decision guide
How to decide
A slim plugged-in projector points to Atom. GV50 is the better fit if an internal battery and ceiling-friendly stand are essential.
With the same throw, the power plan decides
Each has a fixed 1.2 throw, so the Atom doesn't get a closer installation just because its chassis is thinner.
The stand addresses a different problem than cabinet size
A rotating base and vertical adjustment on the GV50 serve bedside and ceiling viewing. The Atom is slim but needs a suitable surface or mount, plus external power.
Be careful with brightness labels
The Atom lists 1,200 ISO lumens and the GV50 500 ANSI. Because the figures follow different labeled standards, don't turn them into a precise head-to-head multiplier.
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.
