ViewSonic 4K Projector with 3500 Lumens HDR Support and Dual HDMI for Home Theater Day and Night (PX747-4K)

Comment

Ive had this projector for almost an year, Ive always had issues with the projector going out then immediately coming back on, I finally had enough and decided to send it back to take advantage of the 1 year expedited warranty. I sent the projector back and view sonic sent a refurbished unit to use while they fix mine. The refurbished unit was DOA (Dead on Arrival)-- So Im still stuck without a projector. I sent an email to customer service telling them about the dead projector and they asked me what kind of HDMI cables I were using. Every email to customer service took 2 days to get a response, so I finally called them and asked for a shipping label to send back my paper weight projector, and Im still waiting-- The picture quality is ok, but this projector is loud spend a few more $$ and get something better

Picked this projector up on a $999 woot deal - seemed too good to be true....and unfortunately was. I have an Epson 5030UB projector in the theater now and I have had zero complaints..great projector, but also 3x the price of this projector. When I unboxed the ViewSonic I was skeptical that a 4K projector 1/3 the price and size could match the quality of the 1080p epson. The pictures attached show my side by side comparison of the two. I tried adjusting many settings and while the image is definitely more crisp, the colors are just completely washed out. Lowering the brightness just made all the whites yellow. The Epson image on the right is even projecting in THX movie mode where the colors are more muted. Needless to say, the ViewSonic is going back. For a budget 4K projector in a very lit area, it might be fine. For a dedicated media/theater, it’s too bright and washed out.

I want to love this projector, but I’ve been plagued with problems. First one I received had a grounding issue and buzzed incredibly loudly whenever it was turned on. Sent it to get repaired on my own dime ($60) because i didn’t install it immediately and it had been more than 30 days. Yep, had it up for all of one day before I shipped it out for 2 weeks. Got it back and guess what, they didn’t fix it. Got in touch again and they agreed to replace it, but not until they received mine back. They did pay for shipping the 2nd time. But I was without the projector again for 2 more weeks. So I finally get a new projector and I can finally hear the normal noise of the projector and it’s pretty loud. I can hear it during almost any scene that is on the quieter side. It’s not just a fan noise either, there is a slight humming that starts a few seconds after startup. The picture quality is great, but it gets to be very distracting during quiet movies and tv shows. Update 3 months in: The quality of this projector is starting to be questionable. I get intermittent sharpness and contrast anomalies when content is anything less than stellar 4K. It will draw a distinct white like around light objects that is very distracting. Strange thing is, I can change to a different picture setting and then back and the anomalies go away. That’s not the worst of it though. Now the left corner of the image is noticeably blurry compared to the rest of the image. Looks like the lens may be dirty, but I’ve cleaned it several times and it is spotless. I know this is a lower cost projector, but it is still $1300 and I definitely expected more.

I originally was undecided between the px727 and px747 because they have similar specs but are slightly different in price, with the px747 being cheaper by ~$200 when I bought this item. I ultimately decided to get the px747 because I would be using the projector in a dimly lit environment that has some light leaking into the room. Because the px747 has higher lumens, I figured this would be the better option for me between the px747 and px727. Overall, the quality of the projector is good. The unit offers the basic features and is the cheapest of the 4k projectors in the market right now. You definitely get what you pay for with this unit. I use it as the focal point of my entertainment center, with a Roku and PS4. I also have a receiver that allows 4k pass-through, so the 4k content from roku/ps4 is actually being shown in 4k on the projector. If you are passing audio to a unit that isnt 4k compatible, you will not be able to see 4k quality. Pros: - Basic standard features - 4k content - Cheap price - Ease of usability - Internal speakers (albeit speakers are mediocre) Cons: - No Ethernet port for direct internet access - No Bluetooth capability - Color quality could be better After 4 months with this projector, I do somewhat regret my purchase. A few reasons for this. Firstly, I think the color on this projector could be improved greatly. I am in a fairly dim room and still the colors dont pop as vibrantly and accurately as the px727 models I have seen. Also, I had issues with the px747. I have noticed the light/lamp flickering on screen. Every so often, the projector glitches out and there is noise in the picture on screen. Additionally, the units speakers stopped working not even 6 months after purchasing the projector. The speakers are currently not producing any sound but the sound will work if connected to external speakers like a soundbar.

Pros: very bright. 4k uhd using xrp pixel shift. the difference between xrp and a 4k dlp chip is NOT significant --- You will never notice the difference in resolution unless you can see both projectors side by side viewing the screen very close. Excellent focus. Cons: absolutely horrible black levels. Washed out color. No lens shift. Very bright gray boarder around picture. (ALL 4K XRP based projectors have this boarder. This PJ just has a very bright one! See my upcoming review on the optima UHD 50 ) Summary: I "downgraded" to this projector from an infocus X10 which is a 1080p projector. Yes, the 747 resolution is much better, and the projector is significantly brighter. But the overall picture quality is not based solely on the resolution nor brightness. The X10 was simply years ahead of those in the picture quality, particularly black levels, color, and apparent contrast. If you’re looking for a presentation projector, this is a good one! If you’re looking for home theater use I would suggest considering the optima UHD 50 or another projector that uses an RGBRGB color wheel. If budget is of the upmost importance and you’re looking to watch movies in a home theater type environment, I would suggest purchasing a high-end 1080 P instead of this projector and less you can afford to move to the optima UHD 50 or better. Again, this would be an excellent projector for presentation use, or daytime use of TV in a living room with lots of ambient light or a similar type environment.

I returned this. It’s not bad, it just doesn’t rival the competition. Get the Optoma UHD50 instead. Same DLP chip, better color, controls, and hardware. It’s also much, much quieter.

Pros - Visually, great value for the money - Bright enough for daytime use without needing to close shades - 2 HDMI slots - USB port able to power a Chromecast Ultra - Useful backlit remote Cons - Audio options lacking (Bluetooth or optical out would be nice) - Loud fan - Gets really hot (can heat up a small room) - VGA? RS232 port? I would have preferred another HDMI port.

I got this about 3 months ago and so far an pretty happy. This has an amazing picture. Leaps and bounds better than my previous Optoma HD26 projector which was 1080p and non hdr with a 100 inch screen in a totally dark room with a 1.0 gain matte white screen at about 8 feet. The HDR looks pretty good. I ordered the factory certified refurbished unit for 1000$. I do have two problems so far. First is the focus nob is a little tricky to get set just right. Not a huge deal, but annoying. Second, when the unit is plugged in, but off for a few days when I start it up again the screen just displays an image with lots of noise and no real image. I have to unplug it and wait for a minute and plug it back in. Hope this isnt a sign that I got a bad unit with limited life. So far I am pretty satisfied with the value of getting a 4k projector for 1000$. Even though technically the projector uses a trick to make it 4k, it is still displaying the same amount of pixels a 4k one would, just some of the pixels are "faked" I think you would be hard pressed to tell the difference between this and "true 4k." Thats pretty amazing to me. It was definitely a worthy upgrade over 1080p.

1. Picture quality out of box was very good 2. No operation Manuel or calibration sheet Include in box . 3. HDMI cable was to short to achieve a 84 inch or greater picture . 4. Overall this prjector is the best value on the market. And is Easley a better value than buying an 75. Inch or larger.

First I must say that this is a pretty good projector. But the various standard default mode settings are grossly over-saturated. So much so that I almost sent the projector back. Fortunately the unit has "User 1 & 2" Mode options for general picture quality settings. Once you de-saturate the picture as opposed to things like its "Cinema" mode, the picture is quite good. It took a lot of playing around to find this out and get the settings down to acceptable levels. Then I do think the optical zoom is a little limited. This allows custom tweaking of picture size vs. available screen size at any given distance and was almost a fatal problem for me (vs the larger zoom on my old BenQ projector.. Another very important thing to know is that with DirectTV you must enable the HD picture resolutions in the DirectTV, Settings, Display, area in both TV Resolution and Video. Turning "Native" on (under Display, Video) will make the presentation of higher resolutions automatic. Without doing that everything will remain at 480i. Brightness is good in my dark theater and any "so-called" light border is not even noticeable. Further the unit for me is quite quiet. But if you are NOT going to need or use 4K, I would probably go with a much cheaper BenQ unit like I had before it quit working. There is not a whole lot of difference when at or below 1080i. I switched over from BenQ simply because it stopped working after the second bulb was needed. Many other BenQ people have had that happen too. That is too short of a life expectancy to keep my business.
