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

Attention effets arc en ciel

I had this product for almost 2 months before it started having a heating issue but was able to contact ViewSonic through Amazon and get it repaired, without any issues, under warranty. Other than that I love this product. It is a solid projector and Im currently projecting at 155in with a very good picture.

I mostly bought this because of the USB C port but this only has a USB port, major waste of time

I purchased the artlii projector energon 2 And this product as well. (In short) The artlii projector energon 2 will do everything the ViewSonic will do except play Gaming Systems in 4k. Movies on the artlii projector energon 2 have the same nearly image as ViewSonic px 701. The artlii projector energon 2 is advertised as an outdoor projector but looks awesome indoors as well. The ViewSonic has a 3D section however information in not IN THE MANUAL. (In Short) if you want to just watch movies in 4k you should buy the artlii projector energon 2(cost apx under $300 compared to the $800 ViewSonic). Biggest Cons : ViewSonic support. ViewSonic support team have very limited knowledge and it is almost impossible to reach a technical support agent. Pros: will play all video gaming system in 4k with awesome pictures. Finally (artlii projector energon 2 is the Winner Here and will play PS5 in 1080p and it delivers and great image quality as well. Once again it looks great indoor and outdoor with 4k movies) ViewSonic has 3d capabilities/ But good luck trying to figure out how to set it up or what glasses to buy for this system. I purchased three sets of active 3d shutters Glasses none of them connected to the ViewSonic) Honestly if it were not for the PS5 showing up in 4k I would return the ViewSonic) Movie Watchers**** save you some money and go with the artlii projector energon 2 looks good INDOOR as well as Outdoor with an Amazing 4k Quality the ViewSonic is indeed slightly better but only a super pro can tell the difference.

After looking around for many bright projectors, I found that for 4000 ANSI lumens, the price was right. I am not disappointed. It’s the best projector I’ve ever had.

I dont have much to say about the brightness or picture quality. The built-in speaker has a very high pitched whine until it has been running for 2+ hours. I would not buy this product again.

I wanted to add a review for using this as a computer monitor in case others were thinking of the same. The unit is very bright. I dont have to close my windows if Im looking at high contrast things like text. Color isnt maybe as good as more expensive projectors, but I found it to be fine. I found that using 1080p resolution for desktop use was better than 4k as the pixels are a bit fuzzy at that resolution which makes text not look as good. This is due to the pixel shifting tech used (any 4k projector sub $1600-2000 will use this). The screen is very detailed at 4k showing movies and games, however, and the pixel shifting kind of adds a bit of an anti-aliasing effect. I dare say I might actually prefer a pixel shifting projector for computer use as it lets you decide between 4k 60hz and 240hz 1080p with both modes having their own strengths. I feel I have two monitors I like for different reasons which is cool. There is just a slight perceptible lag on 4k, but its really not bad. I dont notice any at 1080p 240hz. And it really does go that high, the difference between 120 and 240hz is noticeable, and it looks really good at the high refresh rate. I actually prefer it over my 144hz 1440p monitor. I dont think this would be good enough for esports compared to a 240hz monitor, but its very close. Remember to use the game mode. Overall it works better than I expected as a computer monitor and Im happy with it and feel it was a good value for the money. Other thoughts -I wish the power plug was longer. Im not going to install this in ceiling, and I had to use an extension cord for it to reach down to a plug that is only a few feet horizontally away. -The remote is a bit old fashioned looking. Not a big deal to me but I think ViewSonic should update the design. -Sometimes the unit makes a strange whirling sound that is annoying. Usually it doesnt and it has done it less as I have used it. Its not the fan, it sounds like something is spinning that is not lubricated. When this isnt happening I found the fan noise to be fairly low and constant. -Its very easy to switch between modes like normal and eco, needing only one button to be hit. This is really nice since the bulb has a lifespan. If I know Im going to step away from the computer for a few minutes or am going to just be looking at text I can switch it to super eco in two seconds. -SuperEco at 240hz flickers, changing to a different refresh rate fixes this. Some tips: -Dynamic Eco is basically as good as normal in terms of color and brightness at least when its showing a bright image. Thats my main setting. I think it just dims when the screen is dark. It is better than eco (but not super eco) in terms of bulb life according to the manual. -Make sure your resolution is 1920 by 1080 if you want 240hz. If its 1920 by 1200 if will default to 120hz. -if the projector is located above you, make sure you turn the projector upside down. It will need next to no keystone correction that way which keeps the image at native.

Beautiful picture quality despite is not a native 4K, but after one month of using this projector one white dot appears on the screen :(, then after 8 months and 1000 hours the projector shutting down in less of a minute, so at this point is useless, no response back from the customer service.

It worked for three movies, then died on the fourth. It was 77 degrees out and 25% humidity which is not bad so the unit was not being subject to extreme conditions. Had it all setup, kids were gathered around and ready to watch a movie outside at night. Ridiculous that a company like ViewSonic would produce such garbage. Things happen, i know but I am in Tech for a living and this sort of thing should not happen. Thankfully it was within the return window with Amazon otherwise I would have been out $600

The brightness is sufficient for use in the living room without fully darkening curtains. The top-down side way keystone correction and the zoom function make it more flexible to place the projector. Perfect for movies and playing exercise games.
