Pros
Pro Very low input lag for gaming
This Sony is great for gaming, since the input lag is measured at 22ms, which is pretty much as low as it gets.
Pro Amazing picture
This Sony has a contrast ratio of 120 000:1 which produces very deep blacks. The dark colors are unusually dark even in ambient light. This also helps with the colors, which are very realistic and deep, creating a bit of a three-dimensional picture feeling. It has 1800 lumens of white brightness and the same amount of color brightness. This balance means that the colors are stunningly precise at every level of brightness.
Pro Very quiet fans
The fans are very quiet, making 22 dB of noise. This is one of the quietest projectors overall.
Pro Long-lasting lamp
It has a lamp-life of 6000 hours, which will last for 6-7 years if you watch a movie a day. Though all lamps lose brightness over time so you might want to replace it earlier. Replacements are available for around $300.
Pro Good for 3D content
The VPL-HW45ES has 3D support. Image quality in both 3D and 2D are the same. Though, just as any other 3D projector, the image brightness suffers in 3D mode due to dark glasses. In addition, it has a built in RF 3D Sync transmitter, providing a wider viewing angle and flexible sitting positioning.
Pro No rainbow artifacts
Like LCD projectors, it barely shows any rainbow artifacts thanks to its three-chip SXRD (brand name for LCoS - liquid crystal on silicon) technology.
Pro Convenient set-up
It has a 1.6x manual zoom lens plus vertical and horizontal lens shift. This makes the projector very versatile when setting it up.
Pro Customization options
It has 8 color presets and one User mode, which are all customizable to your taste.
Pro Very good picture quality
BenQ TH670 has a resolution of 1920x1080, producing a detailed Full HD picture. It has a white brightness of 3000 lumens so it's bright enough to deal with ambient light in a family room.
Compared to other inexpensive HD projectors, the TH670 has the best contrast. A contrast ratio of 10 000:1 means there is a reasonably large difference between the blacks and whites this BenQ projects on the screen. This helps create a life-like picture. The contrast ratio (as for TH670’s competitors) is boosted by BrilliantColor technology. Unlike its competitors, the BrilliantColor can be disabled. This lets you choose between a high contrast or better colors, depending on the content.
Pro Quiet fans
The fans produce 29 dB of sound in Eco-Mode. In normal mode the noise-level is 31 dB. From a few feet away, you can not even hear it.
Pro A fairly long-lasting lamp
It has a lamp life of 4000 hours in Performance Mode. If you use it in Eco-Mode only, it will last up to 10 000 hours. In case the lamp dies or you want it to be as bright as new again, a replacement lamp costs $199.
Pro Works as a business projector
Though the TH670 is a great home cinema, it also does well as a business projector. It delivers a very detailed picture with clear content. Even very small black text (5-6 points) on a white background does not get blurry and can be read easily.
Pro Light and small
The projector weighs only 6.6 lbs, so it is easy to transport. It measures at 5.4 x 12.8 x 9.2 inches, making it is easy to store when you are not using the projector.
Pro 3D support
The projector has 3D support, though you will need to purchase suitable 3D glasses since they are not included.
Pro Back-lighting on the remote
The remote has back-lighting on its buttons. Since projectors are used in a dark room, this comes in handy.
Pro Low input lag for gaming
The input lag is 33.1 in game mode, 33.9 in cinema mode, and 35.2 if you turn on Brilliant Color. In other words, the projector is suitable for competitive gaming.
Pro Great built-in speakers
It has a 10W built-in speaker with clear and loud audio, so external speakers might not even be necessary in a small room.
Cons
Con No built-in speakers
It does not have built-in speakers. Though, it’s a home cinema, so external speakers will create a better movie experience anyways.
Con Complicated setup
There is no lens-shift for easier setup, so you have to be careful when first installing it in the room. Though it does have zoom-lens of 1.20:1.
Con Not great for 3D
If you want a great 3D experience, an inexpensive HD projector is not the best option. You will need a large picture size for a good 3D effect. TH670 will have a dim picture if you make the screen large and view it in 3D.
