PX701-4K 3200 Lumens 4K Projector, 240Hz and HDR Support for Smooth Home Entertainment, 1.1x Optical Zoom, Auto V-Keystone, and H/V Keystone for Flexible Setup, and Dual HDMI Inputs

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 don't have to close my windows if I'm looking at high contrast things like text. Color isn't 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 don't 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 don't 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 I'm happy with it and feel it was a good value for the money. Other thoughts -I wish the power plug was longer. I'm 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 doesn't 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 isn't 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 I'm 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. That's 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.

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 me worry about quality control ***Update 12/15/22 I 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 Screens I 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! **** NEW Update: October 22, 2025 Almost 3 years later and the projector is still working good. Picture quality is still impressive from an Apple TV 4K especially with good quality programs! Brightness and clarity on some new movies and programs still look amazing!

1/30/23 Projector stopped working after a year and a half. Contacted Viewsonic and was approved for RMA and was informed that the bulb went bad. It’s a pretty good projector, but the bulb didn't last 20,000 hours in SuperEco mode as advertised. The bulb warranty is only for 1 year and cost ~$200 if you purchase a bulb through them. I decided to purchase a lamp from a third party and just had them return the projector without a working lamp. 3/7/23 Projector came in, i replaced the lamp and after turning it on I noticed that the image was warped in the middle and had to send it back to them for another RMA. 3/23/23 Projector came back and projected a perfect rectangle image out of the box. However, I noticed that the zoom knob was turned all the way to the left(when facing the projector upright) which projected a smaller image. After testing the zoom setting, I noticed that the device was only able to project a perfect rectangle shaped image when the zoom knob is adjusted to show the smallest image up to right dead in the middle. Shifting the zoom knob beyond the middle showed warping at the top center of projected image. I contacted Customer support to report my findings and was issued a replacement. And it comes with a bulb! 4/7/23 Projector came in and is running great again. Projected image is a perfect rectangle from the lowest to the highest settings using the zoom knob. It did come with a new lamp, hopefully this one lasts 20,000 hrs as advertised. Overall, it’s a solid projector from a solid company. The projector is bright, has low latency and high fresh rate. Perfect for gaming, watching movies or even using it as a PC monitor. Only downside was the bulb that came with my projector did not last as long as it was advertised. Customer support was great and responded in a timely fashion.

The picture quality its pretty dang amazing. I understand its not native 4k but still pretty good to me. The brightness is pretty good too. I had a couple of projectors in the recent past, which I have returned, and quality not even close to this one. Obviously this projector was much more. But its kinda, you get what you pay for. Only unfortunate side is that the screen is definitely much smaller than the other ones. At 8.75 ft it projecting approx a 70 in tv. Previous ones were doing about 100 in. But all in all. Im happy with this one. Yes the lamp light is not as long as the led ones but the replacement lamps and the ease of replacement seems simple enough. The price of a replacement is definitely tolerable as well. Would definitely recommend.

I purchased a ViewSonic PX701-4k projector from Amazon last week, it was shipped by Provantage LLC and received by me two days ago. I purchased this projector when my Samsung 3DTV died, so I could continued to watch my large library of classic 3D movies on 3D bluray disks. 3DTV sets are no longer made and the only reason why I purchased this projector was to watch my 3D bluray disks. I believed this projector was 3D capable, because in the question and answer section on Amazon, a customer asked if this projector was able to display 3D and the answer from Viewsonic was that it could show 3D. Also, a number of other customers on Amazon who were verified customers also stated that they have this projector and have used it to show 3D bluray disks. When I received the projector it worked normally in 2D mode except that it had no sound. I went to the 3D menu on the projector and enabled 3D, however, when I put A 3D disk in my Samsung 3D bluray player, I got a message saying a 3D display device is not present. 2D bluray disks in this player play normally in 2D through the PX701 projector except for the lack of sound from the audio out jack on the back. I don't know if this projector has internal speakers, but if it does, then they don't work. I have had no other problem with the PX701 projector other than the fact that I can't get the internal speakers or audio output jack to work. The specifications for the projector I found on one web site do say it has internal speakers. I contacted the seller Provantage LLC and they said I would have to contact ViewSonic directly, which I have done, but I haven't heard back from them yet. I have seen reference to a firmware uprgade on youtube which said the firmware has to be upgraded to use the projector in 3D mode, but there is no such firmware upgrade on the ViewSonic web site. If this is a case of a firmware update, then I'm willing to do that. I don't want to return this projector, because I have no other complaints about it, so I hope Viewsonic will come through with some solution to the problems. I will update this review as I go through the process of trying to get the problem resolved. THIS IS AN UPDATE ADDED ON NOVEMBER 5, 2022. When I contacted Provantage LLC and told them about the problem I was having, they told me there was nothing they could do and I would have to contact Viewsonic directly. I did contact ViewSonic on October 16, 2022 and they opened ticket number 248423 on my complaint. I worked with ViewSonic representatives Juan and Jerry for ten days and tried everything they suggested with no success. We went through all the menus on the projector looking for some setting that would turn off the 3D and sound and found no settings that would account for the problems. I replaced the HDMI cable with a new one that meets the latest specifications, and I tested both my 3D Blu-ray player and home theater sound system with different equipment and there was no problem with either one. I should also point out that the PX-701 projector worked fine as a 2D projector when connected to my Blu-ray player and I played a 2D disk (except there was no sound). On October 27, I contacted Provantage LLC and told them that I worked with ViewSonic for ten days, Juan at ViewSonic insisted that the PX-701 is capable of 3D projection with the version of firmware my projector came with. After working on both problems for ten days, Jerry, at ViewSonic Technical support, concluded that my projector is defective and should be returned. That same day I contacted Provantage LLC and told them ViewSonic recommended that I return the projector. Provantage LLC immediately emailed me a FedEx shipping label and a return authorization number. I returned the projector to Provantage LLC on October 29, 2022. That was a week ago and I'm waiting to hear what Provantage LLC is going to do. I'll update this review again when I find out how and when this issue will be resolved.

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.

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.

Overall, this is a really good projector. The frame rate is surprisingly smooth for a projector, and performance-wise, I’ve been very happy with it. That said, the buying experience was frustrating. I bought the projector, and literally the next day the price dropped by $200. Instead of offering a price adjustment, I was told I had to repurchase it. The second unit I received had black and white dots all over the screen—clearly defective. I had to return it and go through the hassle of ordering a third one. Thankfully, the third projector worked just as well as the first. So while I’m happy with the final product, the process to get there was way more complicated than it should’ve been.

I bought this about 5 months ago. I wanted a projector for a medium sized space, which I could play games at 4k, and watch movies, whilst also being able to switch between my PC and Nintendo Switch 2 (once it was released). I am more than happy with my purchase! Pros - - Can play 4k games - Large screen area (roughly 1.8x1.5m) - Can be mounted upside down. Cons - - Expensive - Fan noise is a little loud, but not overly so - 4k movies are not good to watch - the low Hz (60) makes them jittery Overall though, a fantastic buy! I would buy again if I was to relive the moment with my knowledge!

Hasta ahora, todo muy bien con este proyector. Relamente no necesita estar completamente oscuro para observar una imagen decente. La resolucion es muy buena y el contraste con los tonos oscuros es realmente bueno.

Outstanding product for the price. Excellent for my golf simulator.

Basta settarlo e non spostarlo più.

Dieser Beamer ist Extraklasse. Um unter 1000€ sehr empfehlenswert. Derzeit nutze ich ihn noch ohne Leinwand, da ich aktuell auf eine Entfernung von 3 Metern schaue. Projiziert 110 cm Höhe und 200 cm Breite Habe euch ein Video und Foto dazu Hochgeladen. Superhell und auch bei Tageslicht zu gebrauchen. Es empfiehlt sich eine Kontrastleinwand im Dunkeln, da er auf Weise Wände sehr abstrahlt. Sobald ich die passende Leinwand dazu besorgt habe, füge ich dies hier hinzu. 4k pixelshift ist für mich auf jeden Fall mehr wie ausreichend. Macht Fußball, Kinofilme in einem sauberen Bild. Fire tv stick angeschlossen und ab geht's. Was man beachten sollte ist die Positionierung. Höhe zur Wanddecke, da ich ihn nicht hängend von der Decke, sondern von einem Verbau strahlen lasse. Fazit: Wollte zuerst Retournieren, da kein W-lan, Apps, 3D etc. aber nun doch behalten und sehr zufrieden! Nachtrag heute: ich liebe ihn noch immer! So ein tolles Gerät! Alles funktioniert reibungslos!
