While the ViewSonic LS711HD looks conventional in all respects, from its white case to its large central lens, it takes short-throw projector packaging to new levels. At 5.1x11.3x8.5 inches and 6.9 pounds, the LS711HD is one-third smaller and three pounds lighter than its predecessor, the capable LS710HD. That said, it's 45 percent smaller than, for example, Epson's L210SF, which offers a couple hundred fewer lumens and costs a couple hundred dollars more.The LS711HD was able to slim down from its predecesor without resorting to Wegovy injections in part by removing the LS710HD's internal power supply and resorting to an external power adapter. This power brick is about the size and weight of one for a mid-sized notebook computer, so it may be a little hard to hide in tabletop use and will require some creativity for inverse ceiling mounts. ViewSonic engineers suggest that ceiling-mounted projectors can hide the power supply by using Velcro tape to attach it to the projector's underside where it won't be easily visible from the ground. That said, ViewSonic says this approach has a number of key benefits besides the obvious reduction in size, weight, and noise, including easy replacement in the event of a failed power supply and a 10% to 30% savings in energy that is important for high-use applications like schools and signage.

Viewing Experience | The LS711HD projector offers a range of color modes, with five options available to cater to different viewing needs. The Bright mode provides high brightness at 4,220 ANSI lumens but suffers from a noticeable yellow-green tint, limiting its effectiveness for accurate color representation. Presentation mode improves color balance, making it suitable for displaying spreadsheets and images in well-lit environments, though it sacrifices some brightness at 3,269 ANSI lumens. While the Cinema mode approaches a warmer, more accurate color profile suitable for darkened rooms, the absence of dedicated sRGB or Rec. 709 modes may disappoint users seeking precise HD content matching. The projector includes user-configurable settings that allow for significant customization, including adjustments for color temperature and gamma settings. Overall, the LS711HD is a versatile projector with strong brightness capabilities, but its color accuracy could be a concern for critical viewing applications. |

Its sealed optical components, rated at IP6X for dust protection, eliminate the need for a dust filter, although regular cleaning of the intake vent is advisable. This projector is versatile enough to handle continuous operation for applications such as airport displays and advertising, making it suitable for demanding environments. However, potential buyers should be aware that heavy usage may affect the warranty duration, reducing it from three years to one year for average use exceeding 14 hours daily. Overall, the LS711HD stands out for its robust design and adaptability for both everyday and continuous use. |
