Firstly, wow. Until picking up the Optoma HD141X on Black Friday, I had no idea you could get such bang for your buck!The Good:It's easy to see why this is the Number 1 Top Seller in Projectors (As of Jan '16). For a few hundred pounds you can turn any light-coloured wall in your home into a huge, high definition screen.The image is great, straight out of the box. After carefully placing it to ensure it's level and a decent sized image, a simple twist of the lens to focus and you've got yourself a 1080p Full HD movie, in monster proportions.My current setup gives me a 100" Screen, on a regular painted white wall. Colours are vibrant, brightness is high and the image is sharp.The menu is easy to use. You can choose to run the projector in normal or 'Eco' mode (the latter of which essentially reduces the brightness of the lamp in exchange for longer life and lower power consumption). I have found that 'Eco' mode is more than adequate brightness at 100". Perhaps with a larger image, or in a brighter room, you may be better suited for 'normal' mode.The Bad:Blacks levels leave something to be desired. I was under the impression, being new to projectors, that the black bars at the top and bottom of a widescreen movie wouldn't be 'projected' e.g. would be completely dark. Unfortunately this is not the case, and as such the closest you can get to black is a dark grey. Fortunately this is offset by the 'wow' factor of having a huge, vibrant projected image. It's not something that the average person would pick up on. Apparently the BenQ W1070 has better Black Levels and Colour, albeit you're looking at a more expensive projector.Rainbow Effect. I had read a few blogs and reviews, curious as to what this was. I'm sad to report that I am susceptible to this effect and it can be distracting once you notice it for the first time. It's more noticeable in high-contrast, fast-moving scenes, or if you scan your eyes quickly around the image. Again, apparently the BenQ W1070 doesn't suffer as much from this.It's also a fairly noisy device. I'm fortunate enough to have a budget 5.1 Home Surround setup, so as long as there's something going on you won't notice it. When the action stops and there's some regular, quiet conversation happening, you will hear the whir of the fans. It personally doesn't bother me too much, as I find it no louder than the Xbox One that I use as a BluRay player. Ideally you'd want it quieter, but for the price it's not a huge con.There is no lens shift. You will need to place the projector in precisely the right spot, as there's no flexibility to shift the image further up or down the wall. the BenQ does have a small amount of lens shift, so if you know you can't position this in exactly the right spot, perhaps continue shopping around.The Noteworthy:As expected, the on-board speaker doesn't offer much in terms of a theatrical experience. I've not put this as a con, and it hasn't affected my rating as I don't think anybody expects or plans to use the built-in speaker as the primary means of sound. It's absolutely fine and loud enough to take to a friends house to watch some Football, however if you're even half serious about creating a decent movie/game watching experience you'll use a decent sound system to compliment your visual setup.The remote control has very brightly back-lit buttons. This can be a little jarring half way through watching a movie in the dark.Although the projector is advertised as being 3D, it's important to note that you will need 'active' glasses (the ones with batteries) and a transmitter to sync them to. The glasses alone won't allow you to watch 3D content with the HD141X.It's also worth using a projector-distance calculator to determine how big of an image this will produce given the constraints of your home. There is some (though very little) zoom so you can change the size of the projected image, however you want to go into this informed so you don't have any unpleasant surprises, such as an image too big for your wall. (Google Projector Central for a brilliant calculator that shows min/max distances and projected image sizes)I absolutely recommend this projector if this is as far as your budget can stretch - you're getting a lot for your money. If you're seriously into top quality visuals, and know your LCD's from your OLED's then perhaps save a little more and go for something like the BenQ W1070 or better, to get the deeper blacks and better contrast.Please find attached a picture from my phone showing a frame from Disney/Pixar's Inside Out as displayed on my HD141X.
