Infocus is one of the better rated multimedia projector brands according to average user and expert review score data that we have collected for all projectors.
Unlike most of the other projectors of a similar age and spec to the IN3924 which do not support 3D, the Infocus IN3924 supports 3D.
Has a Built-In Speaker(s)
The Infocus IN3924 has a built-in speaker(s), as do most of the other data projectors that were launched more than two years ago.
We compared all the other multimedia projectors with a built-in speaker(s) to this projector and we think the DELL 1430x[plb_1406483_price] which has better reviews is also worth considering.
1920 X 1200 (WUXGA) Supported Graphics Resolutions
The highest resolution supported by the Infocus IN3924 is 1920 x 1200 (WUXGA). That's 20% more resolution than a 1600 x 1200 (UXGA) projector, which is the most common resolution supported by projectors that are a comparable age to the IN3924. Across all data projectors that have been available for around the same time as the IN3924 the resolution ranges from 640 x 400 to 4096 x 2160.
Very Quiet Noise Level
At only 33 decibels, the Infocus IN3924 has a fairly quiet noise level compared to most of the other 2400:1 contrast ratio projectors that have been on the market for a similar time to the IN3924. The quietest noise level of 2400:1 contrast ratio projectors that were released more than two years ago is 33dB and the loudest is 43dB.
If you would consider a data projector with a louder noise level then you might want to look at the DELL 1430x[plb_1406483_price] (39dB) which also has a higher rating.
Fairly High RMS Rated Power
The average RMS rated power of data projectors that have been around for a similar time to the IN3924 is 7.3W. At 20 Watts, the Infocus IN3924 has a quite high RMS rated power compared to most of the other projectors that were released more than two years ago.
+2 More reasons for
Quite High Number of Colours
With a number of colours of 1,070 million, the Infocus IN3924 has one of the higher numbers of colours amongst data projectors of this age. Multimedia projectors that have been around for a comparable time to the IN3924 have numbers of colours of between 1M and 1,100M, and the average number of colours is 380M.
5 Reasons Against
Does Not Support Full HD
Like most of the other similar spec projectors that have been available for more than two years, the Infocus IN3924 does not support full HD.
Does Not Support Wi-Fi
The Infocus IN3924 does not support wi-Fi, although it is worth noting that most of the other 2400:1 contrast ratio projectors that were launched more than two years ago also do not support wi-Fi.
Very Dim Projector Brightness
The dimmest projector brightness of projectors of this spec and age is 2,600 ANSI lumens and the brightest is 8,300 ANSI lumens. At only 3,000 ANSI lumens, the Infocus IN3924 has a quite dim projector brightness compared to most of the other 2400:1 contrast ratio projectors that were released more than two years ago.
Very Low Horizontal Synchronization (max)
The average horizontal synchronization (max) of projectors of a comparable spec and age to the IN3924 is 100kHz. With a horizontal synchronization (max) of only 91.1 kilohertz, the Infocus IN3924 has a quite low horizontal synchronization (max) compared to most of the other 2400:1 contrast ratio projectors that were released more than two years ago.
+2 More reasons against
Very Dim Projector Brightness (economic Mode)
The projector brightness (economic mode)s of 2400:1 contrast ratio projectors that have been on the market for a similar time to the IN3924 range from 2,400 ANSI lumens to 6,800 ANSI lumens. With a projector brightness (economic mode) of only 2,400 ANSI lumens, the Infocus IN3924 has a quite dim projector brightness (economic mode) compared to most of the other 2400:1 contrast ratio projectors that have been around for around the same time as the IN3924.
