Review: In a light controlled room, this is hard to beat. - I have been an installer and enthusiast for over 20 years. My first install was a giant Barco RGB projector which put out a whopping 800 lumens. Projectors have come along way in every aspect. I chose this projector because I have a room that I can control all the lighting. I am able to make the room almost 100% black. This projector is absolutely stunning considering both the size and price point. It handles 4K material flawlessly. I must note that I installed the projector and used a fiber optic HDMI cable so I do not lose any signal along the path. I am shooting this onto a 100" fixed screen with a gain of 1.1, and it looks absolutely amazing. The lens shift is very helpful but note it is only vertical. There are multiple reviews out there with "preferred" settings to use to achieve maximum picture quality. So I will add mine. Lighting controlled room: Dynamic Iris: High Light Mode: Eco Picture: Cinema (If you set the 4K to Auto this will auto switch to H10 when 4K material is detected) Brilliant Color: On Wide Color Gamut: Off (I know I will get dinged for this, but my family enjoys a slightly brighter picture) Silence: Off We have viewed several movies from DVDs, to Streaming, to 4K Blu-Rays, and this projector will bring out the best in all of them. With that said, please keep in mind that a DVD at best is only 480p, which means it will look the worst on the projector, or any other 4K display. The only gaming I have done is on a regular PS4. I did not notice any lag, but I am not a competitive gamer. Finally, I must address lag from an audio perspective. The video is stunning and the visuals will blow you away when this is set up correctly and you are viewing good source material. There is inherent audio lag/delay when using a projection system depending how far away your projector is from your receiver. In my case, I purchased a 50' fiber optic HDMI cable so I could run it through the walls. Although fiber optic cables have more bandwidth to transport the entire unaltered signal, they are not any faster than a copper cable. Physics still apply here and the signal still has to travel the length of the cable. Not to mention the conversion to and from light at both ends. For my system, the magic number was 50ms of delay on the audio. This syncs up perfectly with the image. I would assume there is a calculation that can be found online for this, but I simply used a little logic and some trial and error. There is roughly 10ms delay for every 10' of cable. You may never notice it if you are running cable directly to a TV, but it's there. When your image is 100+ inches, it is hard to ignore. Finally, I have viewed an installed several projectors that where 10 - 20 times more expensive than this projector. This is the happiest I have been with a small format projector, and I do not feel as though I am losing any performance. I know there are bigger and better projectors out there, but I challenge you to find one for less than double the cost. As with all reviews, please take this with a grain of salt as this is just my experience. I would recommend this projector to anyone who asks.
Review: Excellent Projector at this price point - This is my first time purchasing a projector, but I have experience with buying other high-res TVs and computer monitors in the past. I think for the price point ($1499.99 at the time of writing this review), this projector is well worth the money. For the past week, I have been testing out the capabilities of the projector on 4k movies and games (native and streamed). I thought that the colors on the unit out of the box were superb, similar to what you would find on an IPS computer monitor that has been properly calibrated. BenQ even includes a color calibration report in the box. The sound coming from the 2 5W speakers on the projector is respectable for what they are. They won't get very loud but the quality is definitely good enough for a small outdoor venue or room. I would recommend separate speakers to pair with this projector overall, though. In comparison to the ViewSonic PX-747 4K projector ($899 at the time of writing this), which I initially purchased along with this projector to see which I preferred, you will definitely benefit a lot from sticking with the BenQ. While the sharpness of the two projectors for 1080p and 4K content does not differ vastly, the contrast on the BenQ makes a world of difference. When watching darker scenes in Stranger Things and playing darker levels in Gears of War 4 on Xbox One S it was very hard to make out the finer details and certain objects in frame on the ViewSonic. I tried to adjust the brightness and contrast to fix this but colors ended up just looking too washed out. On the BenQ, however, I immediately noticed an improvement in contrast and HDR quality and had no issues with these darker scenarios. Moreover, the BenQ was much faster when powering on or switching inputs, which doesn't sound like a huge factor but definitely helps if you use it a lot. The $600 jump between projectors, if you have the money for it, is definitely worth it if you want to have a projector that you'll be happy with for long term. I will say that if you are expecting this projector to be "movie theater quality" then you may be slightly disappointed, however. The overall dynamic range is still not as good as a 4K TV at a similar price point, the projector is not bright enough for a well lit room, and the sharpness could be a little better. For something with improvements to those qualities, you'll have to upgrade even further to a better BenQ, Epson, Sony, etc projector that has native 4K. I think for most people you'd be better off spending that money on a good projector screen, projector ceiling mount, speakers, AV receiver, HDMI 2.0 HDCP 2.2 cables, 4K Bluray movies, etc to accompany this projector. You'll get rapidly diminishing returns upgrading to more expensive projectors, while this projector definitely hits the sweet spot in value (at it's very portable weighing only 9 lbs). I'd definitely recommend it!

### ⭐ Good at first but then malfunctioning issues and shoddy support
*by J***N on November 13, 2019*

Disclaimer: This is my first projector but I am very impressed overall. I was at one time planning on shelling out close to 3k for the Epsom 5050 (which does look amazing) but then I realized I had planned my home theater room without a huge throw distance from projector to screen (just under 9 feet) and I was hoping to use a 110" screen. My fears that the Epsom might not quite have the throw ratio I needed led me to look at this BenQ and I'm glad I did. This BenQ isn't what they call a short throw projector but it does have a more generous throw ratio than most other regular home cinema projectors. I'm pleased to say that the picture is stunning and the price saving enabled me to invest in a better amp and speakers for the room. I bought a Panasonic 4K Blu-ray player (UB 420) and it looks stunning in both 4k and 3D. It will make you want to stock up on 3D movies. I have a dark dedicated home theater in a basement and I can imagine this could struggle in a room with natural light. They also say this isn't a great projector for gaming but I have hooked up my PS4 to it and had a great experience. To be fair, I'm not an online gamer where I suppose the input lag could be detrimental. However, for "local" gaming (1 player campaign/story or multiplayer split-screen) I don't notice any lag at all, just a big beautiful image. It has a very nice backlit remote too. I have had a few moments where I have had some glitches from the 4K Blu Ray signal and had to restart the projector but that has been my only negative. This issue might be unique to my individual unit though. Overall, I love it and I know you will too if you have a dark room, especially for the price. Update: I have since had several problems, first with my original unit and then with a replacement. Now Benq aren't answering support calls or responding to emails. I know we are in the midst of a pandemic but this still isn't good enough for such a big company. I've lost all faith in the brand. Stay away!
