Good,excelent

The ViewSonic PX748-4K UHD Projector is a game-changer! I purchased it as a replacement for my TV, and it has completely transformed my viewing experience. The 4K resolution is stunning, with sharp details and vibrant colors that make movies, shows, and games look absolutely incredible.The 4000 lumens brightness ensures a clear picture even during the day, and it works beautifully in my living room without needing blackout curtains. Setting it up was quick and easy, and the range of connectivity options means I can plug in all my devices without hassle.The size and clarity of the image make it feel like I’m in a theater every time I use it. Whether you’re watching a blockbuster or just streaming your favorite show, this projector delivers. If you're looking to ditch your TV and upgrade to something truly cinematic, this is the way to go!

I've had this for about a month now. I've installed many projectors and have some experience here.Overall it's a good projector, the throw distance was perfect for what I needed.Projecting onto a 110" screen from about 10' away. - Hanging from ceiling.I'm using this for daily use. Audio for my setup goes to a soundbar from the 3.5mm jack for normal viewing. When I turn on the receiver, it interrupts the audio from the HDMI and the audio only comes from the surround speakers at that point. Works well and sounds great when needed.Pros:Excellent throw distance for small rooms. - Very forgiving throw distances. - For my screen size, anywhere from 108"-140" throw distance will work for 110" screen.Plenty bright - However it is not powerful enough to overcome the room lights I have. You still want to use this in a space you have good control over the light.It's 4KIt's 3D - Yes, this works well, but I did find myself inverting the images on a couple movies. - Used DLP Active shutter glasses. - https://www.amazon.com/gp/product/B08C9SWQKMIt's small - This is good because I have a low ceiling where this is installed and need people to be able to walk under it.Cons:Can't get this to power up or down with the Xfinity remote (Volume does work after trying a dozen codes). - Still working on a remote config for my system.No optical out. (Would be nice to have for added connection flexibility.)When viewing in 3D, it puts the lamp from Eco mode, back to "normal", and does not put it back when 3D viewing is over. This is the highest brightness setting and uses up lamp hours quicker. - Use one of the Eco modes for longer lamp life.Adjusting the screen is a little cumbersome, but doable. Focus and zoom are stiff, making it hard to really fine tune it.Fans can be a bit loud. They are worse when lamp is set to "Normal".Overall, not bad.The price point for being a 4K projector is good. It's far from perfect, but given the cost and what it can do, I'm happy with it so far.

I love the Key Stone on this projector. Ok, that sounds like a strange thing to start with, but have you ever wanted to try to project on a curved screen? Ya, like I said a strange want... It's very cool!!! Now on to the things you want to hear... It is a very bright projector, and it has a very crisp image. Yes, it works well for 3D using Blue-Ray. Streaming 3D is hit or miss (I'm not sure that is the fault of the projector). I find the colors to look good and HDR10 seems fine. For the price point this can not be beat. I have no review on the auto keystone, I’ve never tried it. Lol

I got this Used - Like New (sold through Viewsonic themselves), but after only about 1,700 hours, the bulb started to go out. So I called Viewsonic and they said that with only a 90 days warranty they can't cover anything, but I could buy a new bulb at their price of $150.00.To me, that resulting limited bulb time indicates the bulb was around maybe half way used already, so LIKE NEW doesn't really come across too well in the use I got out of it. Not the end of the world though, as you can't expect full NEW warranty for used price.So, just be aware that you may buy it Used-LIKE NEW but you'll get a minimal warranty and probably also an already pretty well used bulb by a significant amount of time. I was able to find a new bulb for a fraction of the cost and it's back up and running solid, so at least I didn't have to sink $150 into Viewsonic again for already cutting my experience pretty short.What I do love about the projector though is it's very crisp and bright. Beautiful colors and sharp picture at 4K (I highly recommend you checking it out with 4K content to see it's true ability because it's truly stunning for a projector in this price range). Contrast is pretty good, but as you can expect with this projector type, blacks are dark grey and don't contrast too highly, but you may not really notice, as I am also often stunned at how it looks with the right content, when you don't pay attention to the dark areas...it's a little rough at time with very dark scenes, but not a deal breaker.I have had another Viewsonic 1080p projector for about 10 years and have always loved it, and got that at a great deal NEW (also on Amazon). It has really done a great job for thousands of hours of movie time and games, and productivity that I've used it for, and it is also a beautiful picture even though only 1080p and 60hz. I used it recently when this projector bulb went out and I needed a backup with that 1080p one, and I was still impressed with it. It's a model PJ7820HD and has 3000 lumens, whereas this 4k model has 4000 lumens. There's a noticeable difference with the lumen increase, but 3000 is still great when using in dark or fairly darkened out room.So Viewsonic has been a good, all around company for the 2 projectors now that I've bought through them, just the main hitches being the short bulb life and 90 day basic warranty on this 4k one as well as the following that exists along with my details on resolution and refresh rates offered with it:For resolution and refresh rate: It can only do 4k at 60hz. Or otherwise, to go to higher refresh rates, you have to drop resolution down to 1080p so you can get 120hz or 240hz.I do wish though that they would have implemented/offered at least up to a 1440p resolution at 120hz, but again, 1080p max resolution for up to 120hz or 240hz is what Viewsonic has given this projector to be capable of. 1440p seems should have been doable, so I don't know why they limited that refresh. 60hz at 4k is pretty great overall, but when you game like I do, it's 120hz and up that really shines through for smooth gaming experience at 1440p and up. Movies can even looks quite a bit more smooth if at 120hz or higher, and I do like that effect. Some people don't though (as some compare it to a "soap opera effect" like motion smoothing, when it's much smoother overall, but at higher refresh rate, doesn't have a smeary smoothing affect, so I like it on TVs at least. Not too solid on this projector though). Also, the projector display just doesn't look as good when switched to 1080p for the 120hz or 240hz either, so I've rarely played at that lower resolution just to get the higher refresh rates. HDR seems to stop working, and the colors seem very washed out and low contrast for that. It just doesn't look good and I can't figure out how to make it look and bright and contrast-y and it is when it's at 4k/60hz. Maybe it's messing with color settings and all that do get it to look right, but it automatically goes washed out and feels like HDR doesn't work right when switching to anything above 60hz refresh at 1080p. It's an unfortunate tradeoff, and left me pretty disappointed in the projector for that use case of trying to get any higher refresh and actually enjoy it.Overall, I do recommend this projector, but probably would say when on a sale, so you can feel like you get your money's worth. The tradeoffs I mentioned may make you change your mind if you're picky like me. At least I guess getting it at nearly half price by buying Used "Like New" instead of new makes me feel better about having the downsides.
