So here is the story I am waiting for a replacement from Amazon because I believe it was manhandled during shipping and screwed up the fan(s). happens.Now about this excellent projector. First thing first the black levels are very good on this projector for a projector. You need to run it in smart eco mode and you get great contrast and it's quiet. I know because I had the epson 5050UB and I ran gravity on both in 4k and 3D and they looked almost the same. Maybe the 5050 had slightly better blacks but the 4550i still has great blacks and better highlights and color. I have an oled E6 so i know black levels and 3D. It is also very good at intermittent black detail. Motion is super smooth on this projector and 3D is very good. Sharpness is a standout and it is noticeably sharper then the epson 5050Ub. It is a bright projector and in bright cinema mode it still looks great with some lights on. Now I must say the epson 5050UB is a great projector but unlike the benq, which uses led rated at 20,000 hours, the epson used a bulb rated at 3000 hours and must be changed. This is a very modern projector and you can see it in design,lighting system, and menu system. It is relatively compact and will Def fit into my blacked out cinema room.

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: HighLight Mode: EcoPicture: Cinema (If you set the 4K to Auto this will auto switch to H10 when 4K material is detected)Brilliant Color: OnWide Color Gamut: Off (I know I will get dinged for this, but my family enjoys a slightly brighter picture)Silence: OffWe 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.

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!
