Multimedia projectors produced by Vivitek generally have good reviews compared to other manufacturers.
Has a Built-In Speaker(s)
Like most of the other 15000:1 contrast ratio data projectors that have been available for around the same time as the DX977, the Vivitek DX977 has a built-in speaker(s).
We compared all the other projectors with a built-in speaker(s) to this multimedia projector and we think a cheaper projector such as the Optoma DU400[plb_3419204_price] or you might consider a better rated projector such as the Benq HT2150ST[plb_4013908_price] are also worth considering.
There are a number of other projectors which also have a built-in speaker(s) that you might also want to consider including the Infocus IN2128HDX[plb_3899230_price].
Very Bright Projector Brightness
The projector brightnesss of 15000:1 contrast ratio data projectors that have been around for a similar time to the DX977 range from 2,000 ANSI lumens to 6,000 ANSI lumens, and the average projector brightness is 3,600 ANSI lumens. At 6,000 ANSI lumens, the Vivitek DX977 has a very bright projector brightness compared to most of the other 15000:1 contrast ratio data projectors that are a similar age to the DX977.
Very Big Matrix Size
The matrix sizes of 15000:1 contrast ratio data projectors that were released around the same time as the DX977 range from 0.55" to 0.7". When compared to other recently released comparable spec projectors, the Vivitek DX977's matrix size of 0.7 inches is one of the biggest.
Three VGA (D-Sub) Ports Quantitys
Most of the other recently released projectors only have between one and two VGA (D-Sub) ports quantitys, however the Vivitek DX977 has three VGA (D-Sub) ports quantitys.
5 Reasons Against
Does Not Support 3D
Most of the other new 15000:1 contrast ratio data projectors support 3D, however the Vivitek DX977 does not support 3D.
We think you might also be interested in other multimedia projectors which also support 3D including the Optoma DU400[plb_3419204_price] or the Benq HT2150ST[plb_4013908_price].
Does Not Support Full HD
Most of the other similar spec data projectors that have been on the market for a comparable time to the DX977 support full HD, however the Vivitek DX977 does not support full HD.
We compared this multimedia projector to all the other data projectors with a full HD and we think the Benq HT2150ST[plb_4013908_price] or the Optoma DU400[plb_3419204_price] are also worth considering.
Does Not Support Wi-Fi
The Vivitek DX977 does not support wi-Fi. Most of the other new data projectors also do not support wi-Fi.
Only One USB 2.0 Ports Quantity
The Vivitek DX977 is a one USB 2.0 ports quantity data projector.
+2 More reasons against
15000:1 contrast ratio data projectors that came out in the last year have weights of between 2.3kg and 4.6kg. At 4 kilograms, the Vivitek DX977 is quite heavy compared to most of the other comparable spec data projectors that were released around the same time as the DX977.
3 Other reasons to consider the Vivitek DX977
Released Nine Months Ago
It was nine months ago when Vivitek released the DX977.
Average Noise Level
The Vivitek DX977 has a relatively average noise level (36 decibels) compared to most of the other 15000:1 contrast ratio data projectors that came out in the last 12 months.
If you would consider a projector with a louder noise level then you might want to look at the Infocus IN128HDSTX[plb_3451178_price] (34dB and cheaper), or the Vivitek DW832[plb_3704544_price] (38dB and cheaper).
XGA (1024x768) Projector Native Resolution
This multimedia projector has a projector native resolution of XGA (1024x768), which is the most frequently found projector native resolution on data projectors that were released around the same time as it.
