Based on 1,734 expert and user reviews, Optoma has good ratings for its projectors. Optoma also has good ratings specifically for its 20000:1 contrast ratio multimedia projectors.
Supports Full HD
The Optoma DS347 supports full HD, which is unusual. Most of the other 20000:1 contrast ratio multimedia projectors that were released in the last 12 months do not support full HD.
The Optoma DS347 supports 3D. Most of the other 20000:1 contrast ratio multimedia projectors that were launched in the last 12 months also support 3D.
Fairly Long Service Life of Lamp (economic Mode)
The Optoma DS347 has one of the longer service life of lamp (economic mode)s (8,000 hours) amongst 20000:1 contrast ratio multimedia projectors of this age. Data projectors that have been on the market for around the same time as the DS347 have service life of lamp (economic mode)s of between 4,000h and 24,000h, and the average service life of lamp (economic mode) is 6,300h.
Fairly Big Offset
The offsets of 20000:1 contrast ratio multimedia projectors that were launched in the last 12 months range from 30% to 120%, and the average offset is 90%. With an offset of 115 percent, the Optoma DS347 has a fairly big offset compared to most of the other similar spec projectors that are a comparable age to the DS347.
Quite Quiet Noise Level
The Optoma DS347 has a quite quiet noise level (only 29 decibels) compared to most of the other projectors that have been around for around the same time as the DS347. Across all the new comparable spec projectors the noise levels range from 22dB to 35dB, and the average noise level is 31dB.
It may also be worth considering one of the other 29dB noise level projectors currently available including because of it's better review score, the Optoma EH341[plb_3108586_price].
Alternative multimedia projectors with a louder noise level that you might want to look at include the W331[pl_3372582_price] (29dB), or the DS348[pl_3381925_price] (29dB) both from Optoma.
+3 More reasons for
Across all the comparable spec projectors that came out in the last 12 months the weights range from 110g to 40kg, and the average weight is 3.9kg. At only 2.2 kilograms, the Optoma DS347 is fairly light compared to most of the other recently released comparable spec data projectors.
Very Low Power Consumption (economy Mode)
The lowest power consumption (economy mode) of projectors that have been around for a similar time to the DS347 is 170W, the highest is 370W, and the average power consumption (economy mode) is 230W. With a power consumption (economy mode) of only 187 Watts, the Optoma DS347 has a quite low power consumption (economy mode) compared to most of the other recently released 20000:1 contrast ratio multimedia projectors.
7 Reasons Against
Does Not Have a Built-In Speaker(s)
The Optoma DS347 does not have a built-in speaker(s). Most of the other comparable spec projectors that have been available for around the same time as the DS347 do have a built-in speaker(s).
Does Not Support Wi-Fi
The Optoma DS347 does not support wi-Fi, although it is worth keeping in mind that most of the other latest 20000:1 contrast ratio multimedia projectors also do not support wi-Fi.
Only SVGA (800x600) Projector Native Resolution
The Optoma DS347 has a maximum resolution of SVGA (800x600). That's 53% less resolution than a WXGA (1280x800) data projector, which is the most common resolution.
A SVGA (800x600) projector native resolution is in fact the worst resolution amongst all comparable spec data projectors that came out around the same time as the DS347.
A WUXGA (1920x1200) projector native resolution is the best resolution amongst comparable types of multimedia projector.
Only 800 X 600 (SVGA) Supported Graphics Resolutions
The Optoma DS347 supports a maximum resolution of 800 x 600 (SVGA). That's 79% less resolution than a 1920 x 1200 (WUXGA) projector, which is the most common resolution supported by 20000:1 contrast ratio multimedia projectors that were released around the same time as the DS347. Across all recently released projectors the best resolution is 1920 x 1200 (WUXGA) and the worst is 640 x 480 (VGA).
+4 More reasons against
Quite Dim Projector Brightness
With a projector brightness of only 3,000 ANSI lumens, the Optoma DS347 has a quite dim projector brightness compared to most of the other comparable spec projectors that were launched in the last 12 months. Recently released comparable spec multimedia projectors have projector brightnesss of between 300 ANSI lumens and 5,400 ANSI lumens, and the average projector brightness is 3,400 ANSI lumens.
Projectors with a brighter projector brightness that might also be worth considering include the Acer H6502BD[plb_3826679_price] (3,200 ANSI lumens) which also has a higher rating.
Quite Loud Noise Level (economic Mode)
The noise level (economic mode)s of latest 20000:1 contrast ratio multimedia projectors range from 26dB to 35dB. The Optoma DS347 has a fairly loud noise level (economic mode) (29 decibels) compared to most of the other data projectors that have been on the market for a comparable time to the DS347.
Quite Small Matrix Size
The smallest matrix size of 20000:1 contrast ratio multimedia projectors that have been available for around the same time as the DS347 is 0.45", the biggest is 0.67", and the average matrix size is 0.62". With a matrix size of only 0.55 inches, the Optoma DS347 has one of the smaller matrix sizes amongst 20000:1 contrast ratio multimedia projectors of this age.

Total running cost over 5 years
Running costs for this projector have been estimated based on other similar projectors. If you know how much electricity and water the Optoma DS347uses then please let us know by entering those figures in the boxes above.
Running this projector over 5 years will generate 0.38 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 10 tree seedlings and grow them for 10 years.
