XGIMIAura 2 UHD 4K Ultra Short Throw Projector for Home Theater, Dolby Vision & IMAX Enhanced, 2300 ISO Lumens, 1,000,000:1 Dynamic Contrast Ratio, 60W Harman Kardon Speaker

It really is a feature packed projector - which I suppose you would expect given the value! Very impressively, it has a mechanized shutter which opens and closes when the device is powered on and off, which reveals within the array of lasers which project your picture. Built in to the device is a fully fledged Android (TV) OS with play store and all bells and whistles, so one can install Netflix, Amazon TV, or even third party / streaming - anything on the Android store... All standard apps (browser, youtube) work flawlessly and Youtube will play beautifully at 4K HDR. We have tested it with various devices (a TV streaming box, the built in android, a PC and a laptop) and all worked perfectly at 4K with HDR support too.The settings are particularly impressive, as you can completely customise screen length/width completely and absolutely, it also has auto focus and auto keystone (these can be disabled, if you so wish). The projector remote is pretty simple and works perfectly, as one would expect. I bought a separate, and rather expensive (trust me, you don't want to skimp on a screen I did the research...) projector screen which has sunk a sizable hole in my credit card, definitely worth investing in a decent screen for a projector of this outstanding quality. Being an UST (ultra short throw) projector, it can get up quite close to the screen (or wall) of choice, which makes it incredibly versatile. You don't need to worry about mounting it like other types of projectors, but there is absolutely no sacrifice in any regard for this technology.Built in sound is from the high end Karman audio speakers at 60 watts of power, which has the bells and whistles (Dolby Atmos & DTS support) and it can get really, really loud if you so wish. The audio quality is brilliant, we can hear all of the lows and highs, making out the detail from the smallest to the loudest parts of films and tv shows. You would not expect to hear spatial audio from a device this size (not that it's very small, but typically when you think of surround you think of speakers around the room) but it does project the sound outwards too so it is room filling and cinematic in audio experience too, I would say. Brightness level of the picture is great, ideally you want a dark room but this projector excels nonetheless in various lighting conditions, we have observed.It really shines when playing 4K HDR content, of course normal HD and SD content looks decent. We use the HDMI eARC port to get the highest quality sound and video, although it also has This projector, being a laser UHD one, has a million to one contrast ratio which exceeds the very best current OLED TV's, but you would not get a 120 inch OLED with this picture quality at this value, indeed some of them are 10 times as much as this projector, so it represents OUTSTANDING value too to the point where, objectively, I would say it is the best projector you can buy, not only at this price bracket but even in the higher ones.
