## At a glance

- The listing describes a 1.1:1 short-throw ratio and approximately 100-inch projection from about 7.9 feet.
- Native resolution is listed as 1920 x 1080. The manufacturer describes 4K content support, not native 4K resolution.
- Automatic focus, 6D keystone correction, screen alignment, obstacle avoidance, and 50–100% digital zoom are claimed.
- Built-in apps are claimed to include Netflix, YouTube, and Prime Video, among others.
- The feature description claims dual 20W speakers, while another section describes Dolby-certified stereo speakers without specifying their wattage.

## Pros

- Short-throw design is intended to produce a large image in a relatively compact room.
- Built-in streaming apps may avoid needing a separate streaming device for supported services.
- Autofocus and keystone correction can reduce manual image setup when repositioning the projector.
- The portable form and listed 1.93 kg weight support moving it between rooms.

## Cons

- The listed native resolution is 1080p, so it is not a native 4K projector despite 4K support claims.

## Before you buy

- The listing has inconsistent image-size and distance details: it gives 100 inches at about 7.9 feet, but also lists a minimum image size of 100 inches and a minimum throw distance of 1.15 meters. It also describes a maximum 200-inch image and a maximum throw distance of 5.35 meters. Brightness is presented as both 500ANSI and 500 ansi\_lumens. Confirm the intended room distance and image size, and treat the brightness and 4K wording as listing claims.

## A good fit for

- People setting up a large image in a bedroom, apartment, dorm, or other compact room.
- Viewers who want listed built-in streaming apps and automatic image adjustment.
- Buyers looking for a portable projector for home cinema or gaming.

## Less suited to

- Buyers who require native 4K resolution.
- Viewers needing consistently bright projection in a well-lit room, given mixed brightness feedback and the listed 500 brightness claims.

## Customer feedback

Customer feedback describes positive experiences with performance, image quality, autofocus, sound, built-in apps, and portability. Brightness is a clear point of disagreement, with some finding it adequate and others wanting more. That matters for buyers choosing where to use it: the listed brightness is 500ANSI, but customer impressions vary, so a darker room may be a safer fit than relying on it for bright ambient conditions.
- Positive themes: Customers report positive experiences with sound, autofocus, keystone correction, built-in apps, and portability.
- Mixed feedback: Brightness feedback is mixed, with some customers finding it sufficient and others saying it needs improvement.

## Frequently asked questions

### Is the AC311 a native 4K projector?
No. The listing gives native resolution as 1920 x 1080 and describes 4K support or decoding. That indicates 4K content support with a 1080p native display, not native 4K.
### How far away does it need to be for a 100-inch image?
The listing claims about 7.9 feet for a 100-inch image, but its technical details also give a 1.15-meter minimum throw distance and a 100-inch minimum image size. Confirm the distance and screen-size information for your setup.
### Does it include built-in streaming apps?
The manufacturer claims compatibility with apps including Netflix, YouTube, and Prime Video, plus additional downloadable apps. App availability can depend on the service and software.
### What is included in the listed package?
The package list names the projector, an HDMI cable, a power cord, and a user manual. The listing says the remote does not include batteries, so AAA batteries are not listed as included.

## Offer details
