Wanted a normal throw laser projector for my golf sim space. Was surprised by the size of the unit but the picture is great. Got it mounted up and it was tough to get it aligned due to its weight but I was able to do it. Very happy with this unit.

The item arrived and would turn off. Turns out one of the fans is not working. Impossible to return on find help so far.

The media could not be loaded.

YOU’LL HAVE TO TALK OVER IT. If you don’t see a db rating, assume the worst. Focus ring is hard to dial in (not settle).

OK, point one. This projector was packaged so well that the delivery guy could have kicked it up the 12 flights of stairs to my door without a scratch, and based on my experience he probably did. The unit was held within a cool looking foam mesh that offered just as much cushioning as a solid foam block but without wasting materials. It’s clever, and I appreciate the thought that went into it.Now I’m categorically not in the target audience for this projector. I live in a small apartment with very few blank walls on which to project an image. I absolutely don’t have to room to find a permanent home for this frickin’ enormous unit, and in any case I don’t have the patience to set up a projector just to watch a movie (and I make very few PowerPoint presentations to my wife. Almost none, in fact). I got this purely because I was curious. My most expensive projector thus far cost around $250 and offered more than enough for me, so I wanted to see what many times that price would get me (and as a Vine member I get to test this thing for free - I’m not opening my wallet for a novelty).My first thought on opening the LH710 was that it’s much, much larger than I was expecting. A projector this size wouldn’t be just a little inconvenient to move around, but unwise. It’s heavy, and what’s more it doesn’t have a cap to protect the lens, though the lens is very deeply recessed in the unit so you’d very unlucky to hit it directly if you dropped this thing. No, this projector needs a permanent home, preferably ceiling mounted so it’s out of the way.Now onto the performance, which is quite impressive. I know this thing is designed for professional use, boring spreadsheets and the like, but since I didn’t have a spreadsheet handy I instead loaded up the Dwayne Johnson big budget stupidfest San Andreas and watched some skyscrapers collapse, and lemme tell you they collapsed real nice on a screen that took up an entire wall of my apartment. Crisp as anything. The focus ring above the lens is easy to smoothly manipulate in small increments, so you can dial it in perfectly. I duplicated my desktop screen, which is near perfectly calibrated for accurate colour, and the image cast by the projector was indistinguishable from it. Maybe the blacks weren’t quite as deep, but to be fair the room wasn’t pitch black so the BenQ was fighting against environmental light. Anyhoo, if you want to watch a movie on this you won’t be disappointed. It’s pretty spectacular.My favourite feature here by far is the zoom function. Every other projector I’ve owned had a fixed lens, so the size of the screen was determined only by the distance from the lamp. With the LH710 at a distance of something like 20 feet I could use the zoom to expand the screen by what looks like at least 50%. I didn’t measure it, but the range was very impressive. I also liked the keystone adjustment function, which seems to offer a much wider range of angle adjustments than any projector I’ve tried in the past (I’m guessing it takes a mixture of physical and digital manipulation to achieve, but I’m not sure). I threw the image to my ceiling, and with a few clicks I restored a skewed mess to a perfect 16:9 rectangle.Now onto the negatives, and I’m afraid there are a few.1. The sound quality really isn’t up to scratch for a projector of this pedigree. I know, I know, this isn’t designed for entertainment. It doesn’t needs cinema quality sound that it will never use, but at this price the sound quality should be at least passable. This is *bad*. It’s tinny and thin, with no bass to speak of at all, and there are no options to adjust the sound beyond volume. The built-in speakers on my $250 BOSNAS projector are significantly better. Fortunately the physical connection options in the LH710 are plentiful, so it was the work of a moment to hook up a soundbar through the audio out.2. Which brings us onto the second negative, and the worst in my opinion. While the physical connection options here are great, that’s all you get. There’s no wi-fi and no Bluetooth. If you want to use this thing without blowing money on peripherals to open up wireless options you’re stuck with a wired connection. I’m sure that’s fine for most situations, but at this price it seems needlessly limiting. A couple of months ago I tested a $100 off-brand projector that offered wi-fi connectivity, so there doesn’t seem to be a solid budgetary reason to omit the feature here. Hell, my doorbell connects to wi-fi. This is no longer a premium feature, and including it would have made this a much more attractive proposition.3. Finally, back to the physical connections. There’s a USB port on the back, and I assumed that - like many much cheaper projectors - I could hook up a portable hard drive and play media directly from it. Nope. I’m not entirely sure what this USB port is for and the manual is silent on the subject, but it doesn’t appear to be usable as an input. Again, a real shame.All in all this is a very solid piece of kit. If you’re using it in a conference room and you’re happy to hook up your laptop you’ll be blown away by the picture quality. Seriously, those bar graphs describing the sales growth of your widgets will frickin’ shine, man. Your CEO will be moved to tears. You’ll be carried out on the shoulders of your colleagues. Mwah. Bellissimo.It’s just... I dunno. I can make my peace with the poor sound quality because that’s not what this thing is for, but with a couple more connectivity options this could be a world beater. If I could park this projector on the other side of the room, connect it to my iPad at the touch of a button and a speaker system with the touch of another I’d already be worshipping the LH710 as my new god. Seems like a bit of a missed opportunity, you know?

I've owned a number of projectors over the years and this is probably my favorite. It isn't just the image quality or functionality but it is the easiest projector I have ever owned.What do I mean by "easy?" Well, projectors usually require regular maintenance and bulb changes ever few years. Sometimes you get annoy dust that needs to be vacuumed out or any other number of things you need to do to your projector to keep it running optimally. BenQ has changed all of that. Their design is outstanding and means that this is truly a "set it and forget it" projector. The lamp-free laser projection means there is no bulb to change every 2000 hours and instead will give you over 20,000 hours of optimal image quality before needing to do a thing. The sealed imaging array means no dust. Let me repeat that: NO DUST. I can't tell you how amazing that is. This makes it perfect if it needs to be mounted in a space that is challenging to regularly maintain. This is one of the reasons it is a great option for auditoriums or large conference rooms but is also perfect for the home theater experience.The image quality is outstanding. The 4000 Lumen rating is very good and it gets to around 3000 lumens in it's most accurate modes. It is okay in a well lit room but really shins in conditions of moderate light. In a fully light controlled room, the image quality is stunning. We use it in our living room that has simple blinds and it can be used at any time during the day. The image quality is natural with excellent contrast and very good black levels.If I had one complaint it would really be the lack of wifi. That offsets a bit of the functionality since you need to drag a network cable to it in order to do updates but it isn't a real deal breaker.This is a great projector!!!
