ViewSonic PX701-4K 4K UHD 3200 Lumens 240Hz 4.2ms Home Theater Projector with HDR, Auto Keystone, Dual HDMI, Sports and Netflix Streaming with Dongle on up to 300 Screen

Upgraded to 4k and delighted with this. Picture quality is great and really easy to use. Tried a 4k Epsom but this is far quieter and has a greater range for adjustment. Really recommend this

After trying an LED and laser projector, the winner by far is the ViewSonic PX748 4K, in price and quality.

My family uses it as a projector hooked to a PC. It works great for family movie night. It can be daytime with a bright window nearby and the picture still looks good.

Works great and picture looks great, but it is not 4000 lumens and it is not 250ghz.

I purchased this (and a screen) to be able to take on the road for demonstrations and presentations. I dont know anything about projectors, so take this review with a grain of salt. The positives: First, it fits in my (moderately large) backpack with room for my laptop and associated cords and cables. Big plus. Secondly, it doesnt have to be used so that the angle of projection is perpendicular to the screen surface: the projection can be warped somewhat so that the image appears to have been projected along a perpendicular axis even at an angle. Thirdly, you can make out colours quite well in a normally-lit office. Finally, it accepts USB-c input, so if your laptop doesnt have HDMI out, you dont need to faff about with adaptors (which helps avoid looking unprepared). The negatives: First, you do need quite a big backpack - its not portable in a strict sense (nor is it advertised as such, so its not a criticism of the device, just its suitability to my use case). Secondly, the mechanism by which you adjust the image is tricky (at least I found it to be: this is the first time Ive used a projector rather than having the AV guy at hand to compensate for my incompetence): Id allow 10 minutes after positioning the projector and before presenting to get this adjustment right. Thirdly, the focus is hard to get exactly right--for me this is not a big issue, as I dont have text-heavy presentations (mostly charts), but if you plan on people being able to read smallish text, give yourself a good couple of minutes extra to fiddle with it. It has a whole bunch of functionality I havent used, and about which I cant comment, but I imagine its quite good.

Hands down this is one of the best projectors I have ever used, it blows the water out of the Optoma 4K gaming competitor. The input lag is very, very low and definitely meets or exceeds the advertised 4.5ms. I use this projector primarily for lab research in 1080P mode where latency is a major concern and we are extremely happy with the brightness, response speed, and image quality. The response time in 4k is great as well, but not quite as fast as lower resolutions. Our previous Viewsonic 1080P projector lasted us 10 years, and we still use it today! Happy to have finally found the high quality product we needed, we will definitely continue buying Viewsonic in the future.

Exelente producto lastima que la lampara se daño luego de 10 días y toco devolverlo, pero Amazon se hizo cargo de todo

I purchased this projector refurbished and I received it in fantastic condition, it looks bran new. The picture quality is fantastic very crisp and clear and it looks way better than my 4k tv.. I haven’t had a chance to bring it outside yet for move night I’m really looking forward to that.. I watched a movie in my living room the first day I got it to test it out , it was in the day time and the room wasn’t dark at all and I could see the movie perfectly without any fading.. This was a great purchase, and I’m really happy with it..

Ive been using it for 6 months now and Im very happy with it.

Images is really colourless in a day-time :(
