I decided to review the ViewSonic PJD7720HD Lightstream 1080p 3D DLP Home Theater Projector because I’d liked previous ViewSonic models and I wanted to see how this one measured up. Instead of throwing numbers at you, I’m going to be telling you about actual performance. Instead of just listing the special features you’d find on the box, I’ll also be digging deep into what it does and how it does it. This way you’ll get a true picture of what it offers and you can decide based on that, whether the PJD7720HD is right Projector for you.
- Full HD 1080p
- Easy set-up
- Excellent Speakers
- Amazing DLP Technology
- 22000-1 Contrast Ratio
- PC 3D Ready
Size and Design:
Like all Projectors in the ViewSonic range, the PJD7720HD is not that great to look at, with a rather minimalist design that doesn’t leap out at you as something beautiful to behold. But, it’s also small so will fit into any space you have available and this makes it portable too. Portability is one of the main reasons people buy Projectors over Televisions because it’s very advantageous to own something that produces a great picture but can also be taken to friends houses or out in the backgarden. The measurements are 9 inches by 12.4 inches by 4.1 inches meaning you’ll be able to put it in any suitcase or bag and with the weight being only 5.3 pounds, it’s not going to be a burden to walk around with.
The set-up is easy and can be done in 15 minutes but be careful because without Manual Lens Shift you’ll be using the Keystone and this can import distortions.
Upon completing the set-up the first thing you’ll notice is that the sound on the PJD7720HD is much better than on most projectors in this price range. In fact, the sound is incredible giving a cinema-like feel to movies and an arcade-like experience with games. If you’ve read other reviews you’ll no doubt have heard that this is due to the inclusion of 10W speakers. While it’s true that 10W speakers are excellent, it’s not the full story and digging deeper into the sound system I found enlarged speaker chambers. These help filter out sound waves better with less distortions, and there’s also some great amplifiers that deliver sound between the 20HZ and 20KHZ range they use in cinemas.
Further good news comes in the form of the Native Resolution which is 1920 by 1080p, and so the PJD7720HD does offer Full HD viewing. Not all Full HD is the same though, and this is something buyers find confusing. 1920 by 1080p refers to the number of pixels a projector is capable of displaying horizontally and vertically on screen. These numbers are specifics manufacturers constantly try to get you to focus on, but again they only tell part of the story because the quality of those pixels is decided by Contrast Ratio and technology used inside. Fortunately with the PJD7720HD, as well as a full HD pixel count you also get a 22000-1 Contrast Ratio meaning white and blacks will appear deep and vibrant. And, the SuperColor Technology inside produces over a billion colors from a 6 Segment Wheel. All this combines to create some of the best visual experiences you’re ever likely to find on a projector or TV Set.
It’s not all good news though, because you may have looked up the manufacturers description which contains the term ‘PC 3D Ready’. This term is highly misleading and many buyers think they have a 3D Ready device when they see it. The reality is that you won’t be able to view 3D Blu-Ray Disks or any 3D at all, unless you have a PC that has 3D Broadcasting technology inside. This is because the PJD7720HD only reads Frame Sequential 3D, which is a 3D capability limited to the 1280 by 720p resolution common in computers but not currently offered by projector manufacturers. So while you get an amazing Full HD picture on the PJD7720HD, you’ll never view 3D on it unless you have a computer capable of Broadcasting 3D. If you do, there are good connections provided by ViewSonic so it should be easy to hook up it up to the PJD7720HD for 3D viewing up to 300 inches.
The Lumen count is 3200, and the Lumens perform well so you’ll be able to view up to 100 inches in ambient light, which is very good, but it’s not really what people will buy this for. With the 22000-1 Contrast Ratio, movies outdoors will be a special experience so I think the majority of buyers will want to take it into the back garden with some Popcorn. There are some distortions as you enlarge the screen, but no more so than any other good quality DLP Projector, and you certainly won’t find distortions bothersome. They’ve included an MHL connection too, so you could even hook up your Tablet and download a movie from the internet for large screen viewing outside. If you get a dongle you can do that wirelessly so there’s less clutter around the house.
While 3D is rather limited, the HD viewing capability’s of this projector are insanely good and are definately worth a purchase. It’s in the top 10% of all Projectors I’ve tested so if quality cinema is what you need, then this is the Projector for you. The Speakers are wonderful, with large chambers, and 10W of sound. The Lumens perform well too so viewing in ambient light is very easy and clear. So it all comes down to how important 3D viewing is to you. If it’s not that important then you’ll be in heaven with the PJD7720HD, but if it is important then you should purchase one of the many 3D Projectors available on the market.
