We checked 1,734 user and expert reviews for Optoma projectors and found that on average Optoma has good reviews. We also found that Optoma has good reviews specifically within its 18000:1 contrast ratio data projectors range.
Supports Full HD
Unlike most of the other projectors of this spec and age which do not support full HD, the Optoma DS346I supports full HD.
The Optoma DS346I supports 3D, as do most of the other comparable spec projectors that were launched around the same time as the DS346I.
We compared all the other projectors which support 3D to this data projector and we think because of it's better review score, the Optoma DX342 is also worth considering.
Has a Built-In Speaker(s)
The Optoma DS346I has a built-in speaker(s). Most of the other 18000:1 contrast ratio data projectors that were released more than a year ago also have a built-in speaker(s).
It may also be worth also looking at one of the alternative multimedia projectors with a built-in speaker(s) currently available including because of it's better review score, the Optoma DX342.
Very Long Service Life of Lamp
Across all the projectors of a similar spec and age to the DS346I the service life of lamps range from 4,000h to 7,000h. The Optoma DS346I has a very long service life of lamp (7,000 hours) compared to most of the other 18000:1 contrast ratio data projectors that are a similar age to the DS346I.
The weights of 18000:1 contrast ratio data projectors that came out around the same time as the DS346I range from 2.3kg to 4.9kg. With a weight of only 2.4 kilograms, the Optoma DS346I is quite light compared to most of the other data projectors of this spec and age.

6 Reasons Against
Does Not Support Wi-Fi
The Optoma DS346I does not support wi-Fi, although it is worth keeping in mind that most of the other 18000:1 contrast ratio data projectors that were launched around the same time as the DS346I also do not support wi-Fi.
Only SVGA (800x600) Projector Native Resolution
The highest resolution of the Optoma DS346I is SVGA (800x600). That's 77% less resolution than a 1080p (1920x1080) multimedia projector, which is the most common resolution. The best resolution of all similar spec projectors that are a comparable age to the DS346I is DCI 4K (4096 x 2160) and the worst is nHD (640x360).
Very Dim Projector Brightness
Multimedia projectors of a similar age and spec to the DS346I have projector brightnesss of between 3,000 ANSI lumens and 3,500 ANSI lumens. With a projector brightness of only 3,000 ANSI lumens, the Optoma DS346I has a quite dim projector brightness compared to most of the other 18000:1 contrast ratio data projectors that have been around for around the same time as the DS346I.
It may also be worth considering one of the alternative 3,000 ANSI lumens brightness projectors currently available including the Optoma DX342 which has better reviews.
Very Low Horizontal Synchronization (max)
The average horizontal synchronization (max) of projectors of this spec and age is 97kHz. At only 91.1 kilohertz, the Optoma DS346I has a quite low horizontal synchronization (max) compared to most of the other data projectors of a similar type and age to the DS346I.
+3 More reasons against
Very Low RMS Rated Power
The Optoma DS346I has a fairly low RMS rated power (only 2 Watts) compared to most of the other data projectors that were launched around the same time as the DS346I. Comparable spec projectors that were released one year ago have RMS rated powers of between 2W and 16W, and the average RMS rated power is 13W.
Very Low Vertical Synchronization (max)
The lowest vertical synchronization (max) of projectors that have been around for around the same time as the DS346I is 0.085kHz, the highest is 120kHz, and the average vertical synchronization (max) is 57kHz. At only 0.085 kilohertz, the Optoma DS346I has a fairly low vertical synchronization (max) compared to most of the other projectors of a comparable spec and age to the DS346I.

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 DS346Iuses 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.
