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

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.

Clear bright nice upgrade from 1080p benq

Great picture and price. Can be a little loud, I definitely would only use in a windowless room.

Excellent. Easy to use and setup. UHD resolution.

pour le prix cest assez surprenant, je lenvoie présentement sur un mur noir et cest déja tres bon , limage prend tout le mur ou presque, on se croirais au ciné :)

I ordered the px748-4k for gaming and occasional movies. The input lag is negligible, so thats good. Color accuracy is okay, but in HDR mode, there is A LOT of banding. Black levels are the worst I have ever seen on any projector EVER. this is my 5th projector. I use a .8 gain matte grey screen, and blacks are light grey at best. I am not surprised as its to ve expected with DLP projectors, but this is especially bad. Anyway, all in all, i dock a star for terrible black levels, but otherwise decent value for the money. For daytime with lots of ambient light, good option. For dedicated theatre with light control, not so much.

Only qualms are I wish the volume had more range (I have it hooked up to separate aux speakers and have to change those - which dont have a remote - if i want a meaningful change in volume) and same with brightness (its bright enough but i wish it could go darker!). also its not Smart so if you want to connect it to the internet (which almost everyone does) you need a separate smart device like a Roku or Chromecast

This projector is bright but it does lack color greatly. It is 4k and gaming in this is flawless. I also have a viewsonic 1080 projector and it has a double rgb color wheel that produces way better colors. Difference is this can be used during daylight hours. Speakers are better on my 1080 projector these are very weak you will need a sound bar. The shipping upset me the most. No padding or support other than Saran wrapped in plastic. I hope it lasts.

The project was bright and playback of video was incredibly smooth. With USB-C port, I was able to connect my iPad and MacBook with ease as well as charge my devices at the same time. The image is huge and perfect for my needs when considering a short throw projector.
