ViewSonic PX748-4K UHD 4K Projector with 4000 Lumens, 240 Hz, 4.2ms, HDR Support, Auto Keystone, Dual HDMI, and USB C for Home Theater, Stream Netflix with Dongle

Very good, even with sunlight. Does take a while to turn on but that’s normal. I do wish it had Bluetooth for exterior speakers as the speakers are not very good.

I have to say I am thoroughly impressed. Pretty much a WOW experience from the second I turned it on. Bright and vivid colors, even in a lit room. 4000 lumens in 4k is pretty hard to beat at this price point. Believe me when I say that you get way more than you pay for with the PX748-4K. I had an Epson home cinema and this blows anything out of the water in the $2k and under category. Don’t hesitate to buy if you are looking. My Xbox looks amazing and on screen play is smooth with low latency enabled on the projector. I bought a tv tuner box and this thing is amazing for watching any sports game on the big screen. I project onto a 110” screen and have a semi lit basement unless it’s night time. Beautiful picture night or day!

I bought this projector for a set up in the backyard for movies and while it is great crisp in color and projects. Well it is missing some of the adjustability to smaller screen sizes on further distance quality and contrasts are amazing. Would definitely recommend to anybody that needs a projector within this price range.

I put a lot of work into picking this projector. I wanted a very high quality projector, not just one that works. This projector filled that function perfectly. It is incredibly bright, there is no lag, it is quiet, and very easy to use. The image quality is exceptional. As with all projectors I have used, it can be difficult to use in daylight.

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 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.

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

Possibly the most impressive piece of tech I've ever ended up buying from Amazon. The picture quality has to be seen to be believed. I tried taking a few shots with my phone, but the image quality of the photos were so misleading in comparison to how it is to actually watch something on the projector that I've ended up not including them. The fan is almost whisper quiet too. The only niggle, if anything, is that the onboard speaker really isn't fit for purpose, but there's plenty of options to connect your own sound system so that doesn't detract much.

Perfect for what I was looking for

Llevo año y medio con el producto, usandolo alrededor de 4 horas diarias, imagen perfecta, nunca se ha calentado o apagado, pienso que la compra fue excelente.

My 5 year old pX727-4k had a more vibrant and sharper picture, i replaced it because it kept overheating maybe it was just this particular device but the image did not focus well and text had a clear separation of colours and the picture was slightly washed out

En remplacement d’un appareil bien plus cher : qualité d’image de même niveau, c’est à dire très correcte ! En revanche, la qualité sonore des ho n’est pas au top mais, comme nous utilisons la sortie audio vers un ampli hi-fi : aucun problème. Le ventilateur est présent mais sans être gênant ni plus bruyant que notre ancien appareil. Je recommande.
