What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

Third-party reviews

What customers like about Acer H6518STi

  • 3500 lumens keeps the picture bright with the lights on.
  • A picture up to 303 inch makes a large screen possible.
  • A minimum throw of 0.5 m lets it sit close to the wall.
  • Eco mode cuts the noise from 36 dB to 27 dB.
  • Two HDMI ports can take a console and a streaming box at once.
  • The lamp lasts 5000 hours, or 10000 hours in eco mode.

What customers don't like about Acer H6518STi

  • Noise of 36 dB in normal mode is easy to hear in a quiet room.
  • The 3 W speaker is only good for quick clips.
  • At 2.95 kg it is heavy to carry between rooms.
  • There is no motorized zoom, so setup takes more hands-on adjustment.
  • The 255 mm body needs a deep shelf or a ceiling mount.

Verdict

Rooms with the lights on suit the Acer H6518STi, a 1080p projector with 3500 lumens and a minimum throw distance of 0.5 m. It fills a screen up to 303 inch, so you can place it close to the wall and still get a big picture. It also works on a ceiling mount. Auto keystone correction helps when the projector sits at an angle. The trade-offs are noise and sound. Noise is rated at 36 dB in normal mode, and eco mode brings it down to 27 dB. The built-in 3 W speaker is only good for quick clips. At 255 mm thick, it needs a bit of shelf space. It suits a family movie room or a gaming setup where people will add a soundbar.
