ViewSonic X100-4K 4K UHD Projector with 1200 ANSI Lumens, Harman Kardon Speakers, HDMI, USB, 125% Rec 709, and Frame Interpolation Technology for Home Theater

This is an absolutely stellar product. The picture quality is phenomenal. The onboard speaker system is surprisingly robust. The auto-focus feature works flawlessly. The system is extremely portable and fast to set up. I've used this for client presentations in a conference room, at client meetings I've had outdoors during COVID (even looks decent in daylight), and we've used it for family movie night as well. Performed great in all settings. My biggest word of advice, however, is DON'T CHEAP OUT ON THE SCREEN. You're paying a decent chunk of change for the projector, so make sure you're getting a "4K screen" to match. I've tried this using a low-quality outdoor screen setup and the quality drops off when using outside during the daytime.

I've been looking FOREVER to find a 4k short throw projector to replace my EPSON 1060 and this was the only one with the throw distance that could fit in my room and match the size of the screen we had.I loved the color with the 3 LCD chip on the Epson and was hoping to get one of theirs but ALL the dang projectors were bulky and too long of a throw.As this was literally the only one that worked that wasn't a ultra short throw ( I have family with small children that come by ) that plays 4K it was technically my only choice if I wanted to play on the ps5 in all its glory. Luckily I have the ps4 Pro and could at least test its 4k capability AND HDR . The results were at times good, and other times...ok. Particularly for the HDR, more on that later.Pros:-Very sharp 4k image, good colors, deep reds-Decent brightness for some situations, would still recommend a darker room but can preform well with some ambient light-Short throw is super short (0.8 for 100in screen)-Speakers are the BEST speakers I have heard on a projector, though I listen through a surround sound set up myself-Wireless dongle it comes with works, has some apps that are useful for on the go viewing. (youtube, pandora, web browser) but not a whole lot of app choices. No google or apple store.-ability to use as a bluetooth speaker with the option to turn off the light element, very nifty.-LED light with DLP has almost completely gotten rid of the rainbow effect that I would see with other DLP projectors-DOES have screw mounts on bottom to hang from ceiling ( that's how I have it )-App that lets you mirror your phone, for both ios and android, on the projector. It's a bit too janky to watch videos from your phone on it, but fun for slideshows and memes or whatever.-aux output for aux speakers or bluetooth if you wish-Usb C input for phones or charging but mine didn't work for video (Samsung s10)CONS-THE CONTROLLER SUCKS! I did not receive the cool wheel controller, I got a simple black crappy buttons controller that only registers half the dam time. Just turning the thing on is a freakin chore, almost negating all the positivity given for the few apps it do have. You have to point it at a particular part of the projector and even then sometimes it won't work.-Eco mode ironically keeps overheating the projector and forcing it to shut down. It does consume less energy and dim the screen which is fine, but I think it also underpowers the fans too much.-The HDR on this sucks. It's too blown out and the colors are all wrong. I tried to recalibrate but no go. I don't know if an update could fix but I would at least hope so. Benq did a better job with their HDR solutions, though still not perfect.-The controller is freaking garbage, seriously-The app it comes with is bare bones and only allows you to make a few selections. If it allowed me to be able to use the app instead of the dumb controller I'd be nicer, but it doesn't allow you to even TURN ON the freaking projector, only turn off and use arrows to make a choice. Why can't it just mirror the projector app? Dunno.-It has an automatic focus and keystone, both digital and can only be controlled with the controller or the wheel button on the projector. This is a con because the Keystone is ONLY vertical, and the Focus needs to be done a number of times as it seems to randomly go out of focus, or at least miss the focus while it is apparently warming up.-The frame interpolation deal sometimes wrecks the signal. I'll get static around the edges that only go away if I restart the projector and turn of the setting. I just keep it off now.-There is some Lag, it's not that bad really, about as much as the Epson I had am still able to enjoy rocket league on it, but if you're sensitive to lag the Benq TK850 is a decent 4k gaming option but a longer throw :/So it's pretty good, if you need a short throw 4k projector it is as of today basically your only choice unless you want to go ultra short throw.But don't get for HDR, still needs work.

If you're looking for a ceiling-mounted projector, this one is an excellent choice. The picture quality is outstanding for the price, and the lamp life of 30,000 hours is unparalleled. You can easily use a Google Chromecast plugged into the projector or a receiver to stream apps without any issues. As long as the size and weight are not a concern for you, this projector stands out as a top option in its class, in my opinion.

Not good. Advertised as android and aptoide based app store. But cannot install disney+, hotstar, prime video, hulu, HBO. Pathetic app store. Need to add additional roku device just to add streaming. Very bad. Not a single wire device. Need to attach external device.Otherwise picture quality is very good in very bright room. No need of white projector paint or screen. Just plain wall and enjoy. Speaker is not that good. But can work for non audiophile. Light weight and can move it easily. Setup is easy. But manual keystone is not that great as well auto does not help to make screen size go straight.

I bought this projector for watching movies on a screen in my backyard. The main reason I chose this projector was the built-in sound. For this purpose, it's a good projector with the following caveats:- the built-in speakers are really good, but the size of your audience is limited because you need to be fairly close to them to hear them well (I'd say within 12 feet); unsurprisingly, there is also the usual problem of overpowered sound effects and hard-to-hear dialogue (tough to find a happy medium volume level); outside, the fan noise some mention is not a factor- the picture—once it's totally dark outside—is fantastic; you will not see much without total darkness- the interface is clumsy, but you can use some streaming services (e.g., Netflix, Amazon) and connect smartphones to play things; I have had no success connecting a hard drive and...- if you want to use a 4K player or regular Blu-Ray player make sure it is brand new, with HDCP 2.2; I tried to use two different Sony players with an earlier version of the HDCP copy-protection nonsense and they would NOT transmit sound at all (picture was fine); I used an LG 4K player with HDCP 2.2 and it worked beautifully with sound and picture over HDMI. I tested this issue every which way from Sunday with no change in result.If you're planning to use this with a physical blu-ray player, even one that is only a few years old, you may be out of luck. I went several rounds with Viewsonic tech support on this problem, but the end result was to tell me to contact Sony. I *suspect* that the copy protection scheme is what caused this, but I don't know that for sure (it was the only variable different between the three players I tried, all of which worked just fine when plugged into other screens).Great for the extremely tech savvy or the lucky who happen to plug in a thing that works right away.
