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 upgraded my projector for this one as I wanted to be able to watch NHL games with more clarity and smoothness for the speed of the game. It will never match the sharpness of a TV but I have to say that I am pleasantly surprised at how good a job it does. I am happily watching NHL games using this new projector.

We had problems with this projector from the beginning. The picture is clear but it freezes every 10 to 15 minutes. Originally we thought it was the transmitter we connected to the machine but when we connected directly to the machine with a quality hdmi chord it still froze. I would not purchase this machine again. Very disappointing.

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 dont know if this projector has internal speakers, but if it does, then they dont work. I have had no other problem with the PX701 projector other than the fact that I cant 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 havent 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 Im willing to do that. I dont 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 Im waiting to hear what Provantage LLC is going to do. Ill update this review again when I find out how and when this issue will be resolved.

I really wanted to love this projector but I am so disappointed in the shadows on each side of the projection. There is nothing in the way and no matter the setting adjustments, the shadows are always there. Viewsonic is my go to in projection but they have failed to reply to my concern with this projector.

Its was great

Great projector. Plenty bright Unfortunately, my HP Laptop with UHD video card is outside the range of what it accepts. Need to create a firmware update so the projector can process the signal. The projector works fine with older HP laptops, Microsoft Surface and Samsung tablet.

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

Upgraded from a 720 projector. Image is a huge improvement. Did not realize it would require an upgrade on my amplifier so that it would relay the upgraded video signal. Sometimes the image looks slightly distorted but it could be from the signal. Overall satisfied.

Projector funktioniert nicht mit Chromecast. Keine Video - nur schwartz bild - aber mit audio. Für uns das ist ein Dealbreaker unf für diese Prise das kann nicht passiert.

Comme quoi, il ne faut jamais répondre trop vite. Le vidéo projecteur fonctionne avec le son pendant 21 minutes, après il y a comme une surchauffe et il ny a plus de son en sortie du vidéo projecteur!!!!! Jinvite le fabricant ou le distributeur de ce produit à entrer en contact avec moi, car je risque de devenir rapidement désagréable! 21 minutes cest peu pour un produit que jai reçu le 23 novembre 2022.
