ViewSonicPX701-4K UHD 4K Projector with 3200 Lumens, 240Hz, 4.2ms, HDR, Auto Keystone, Dual HDMI for Home Theater

Awesome projector at this price point - bright, clear, low noise. No issues so far with daily use in bright or dark timeframes. Be sure to adjust the custom settings to fine tune color and other levels.

First things first, because there is no mention anywhere of 3D support in the specs or product description there are a lot of comments out there stating that the PX701-4K isn’t capable of 3D. This is incorrect. It does in fact support 3D and it looks great! The older versions that were initially shipped did not support 3D. However, since then ViewSonic has made the necessary hardware & firmware upgrades to correct this. Now that the 3D speculation is out of the way let me talk about the projector. It’s a great 4K projector considering the price tag. True, it’s not native 4K but it does produce 3840x2160 pixels when inputting a 4K signal into the projector. The projector does this. by what’s called “Pixel Shifting “. This is done to expand the native 1080p resolution to produce an effective 4K image on the screen. So, basically, you’re still getting 4K resolution without the much higher price tag you would pay for a native 4K projector. When you play 4K content the projector also displays 3840x2160 on it’s display on the screen. Another nice thing is that it supports HDR & HLG. However, it does not support Dolby Vision which is not a dealbreaker for me. The 3200 ANSI lumens produce a nice bright and vivid picture. I also really like the auto keystone feature. I have the projector sitting on a coffee table which is much lower than my screen and I didn’t have to adjust anything. The projector automatically adjusted the image perfectly. The fan is pretty quiet as well and If you have a surround system you won’t hear it at all. I haven’t tried gaming on it yet but if the specs are correct this should be great for gaming too! Overall I’m satisfied with the projector.

This would have been a 5 Stars projector if the first one I received was not defective.I was really impressed with the picture quality of this projector once I got it working. Which makes it a worthy replacement of my previous Mitsubishi DLP HD projector.Unfortunately, it was clear that I received a defective unit !!!!!!!!! This was clear to me within minutes of plugging in a 4K Apple TV unit as the source. I immediately heard a loud grinding sound. stopped everything unplugged everything and restarted... The same grinding started again. It was so loud and actually louder than my coffee beans grinder-No kidding!I removed the HDMI and connected a brand new 4K Apple TV that I had intended for this projector. It seemed to work fine and allowed me to adjust the image to my taste. A lot of control over color, picture quality. Overall excellent picture quality in 4k bright and detailed.On the first unit that was defective, there was somewhat a loud flickering sound -similar to an old 16mm projector running a film that was not as loud as the grinding sound I experienced with the first Apple TV I connected. It seemed really strange. When I pause the show, the sound stops, when I resume playing the show, the sound returns. I had to send it back and repurchase it again. I will update this review once I receive the replacement.Pros:-Super bright picture - that you can watch even with some daylight or soft dim light in the room.-High Quality picture-Beautiful colors-Smooth gradients and grayscales-Good on screen menu-Responsive remote (if you want the backlit version of this remote, it comes only with the PX 748 model)-Smooth zoom and focus ring for easy adjustment-Very Sharp picture from corner to corner-Auto Keystone feature - saves a lot of time and effort.-3 years warranty.Cons:Defective unit - makes ne worry about quality control***Update 12/15/22I received my PX-701 4K replacement! Very quiet fan which confirmed that the first one I received was defective! Stunning picture quality on a good quality 100" screen ! I attached several photos from Apple TV as the source with 100" electric motorized screen by Elite ScreensI do recommend this projector! It is a bargain for a 4K projector under $1000.***Update 12/28/2022. I'm truly in love with this projector, specially after testing 5 different projectors from different brands. In that $900 range, I haven't seen a single 4K capable projector that comes even close to this 3200 lumens brightness and picture quality. I highly recommend it!

DISCLAIMER: This review comes following just one evening's use of the projector - more specifically, one two-hour soccer match plus the 30 minute pregame show.The colors are brilliant and the screen detail is magnificent. We replaced a dead 1080 i/p projector in which the bulb exploded and brought it to a saddening death. We were completely satisfied with the 1080 Epson. This ViewSonic machine is in a totally different class.Going from 1080 to 4K with such bright and brilliant colors was actually unsettling. The detail was astonishing. I'd swear I could see the ribbing on the soccer players' socks. Even the faces of fans in the stands, the vibrant color of the soccer kits, the texture of the grass on the pitch, all of it was just astonishing.Then you really see the difference when you see commercials, or just standard scenes from studio shots. I even took a quick break to look at the news. All of it was just overwhelmingly crisp, bright, and colorul.When my wife came into the room for the first time, mumbling "Okay, I gotta see this..." she exclaimed, "Oh, wow!! That's amazing! It's so bright that it is almost painful." We're just not used to it.The only drawback came because of my own configuration. The control center is at the front of the room. We have a 30' run of high-end HDMI from the control center to the projector mounted on the back wall. The predecessor projector needed a signal booster to make it work. I had completely forgotten that unit was in place. I burned three hours trying to figure out why the ViewSonic would not detect our Roku device or the DVD/BlueRay. Just a black screen. I eventually traced the problem to this signal booster. Removed it and "voila!" Everything worked. The projector auto-detects what is the maximum resolution it can display with the attached device.Really - no complaints at this time. I believe this was a solid buy.
