7 Reasons For
Running Costs Are Low
The DS346I is one of the more economic to run multimedia projectors of a comparable age and type that we have assessed for running costs. Based on typical energy prices and usage levels, we estimate the DS346I will cost only £76 over 1 year to run.
Optoma Has Good Projector Reviews
Optoma 18000:1 contrast ratio data projectors have good ratings on average and across all multimedia projectors Optoma is one of the better rated brands.
Supports Full HD
Unlike most of the other multimedia projectors of this age and spec which do not support full HD, the Optoma DS346I supports full HD.
The Optoma DS346I supports 3D. Most of the other comparable spec data projectors that have been available for more than a year also support 3D.
We compared this data projector to all the other data projectors which support 3D and we think the Optoma DX342[plb_2985138_price] which has better reviews is also worth considering.
Has a Built-In Speaker(s)
The Optoma DS346I has a built-in speaker(s), as do most of the other 18000:1 contrast ratio data projectors that were launched around the same time as the DS346I.
There are a number of alternative projectors with a built-in speaker(s) currently available that you might also want to look at including the Optoma DX342[plb_2985138_price] which has better reviews.
Very Long Service Life of Lamp
When compared to other 18000:1 contrast ratio data projectors that were launched around the same time as the DS346I that we have assessed, the Optoma DS346I's service life of lamp of 7,000 hours is one of the longest. Projectors that were launched around the same time as the DS346I have service life of lamps of between 4,000h and 7,000h, and the average service life of lamp is 5,000h.
+2 More reasons for
Across all the similar spec projectors that are a comparable age to the DS346I the weights range from 2.3kg to 4.9kg, and the average weight is 3.6kg. The Optoma DS346I is fairly light (only 2.4 kilograms) compared to most of the other 18000:1 contrast ratio data projectors that were released around the same time as the DS346I.
5 Reasons Against
Does Not Support Wi-Fi
The Optoma DS346I does not support wi-Fi. Most of the other similar spec 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 53% less resolution than the most common projector native resolution of WXGA (1280x800). Across all projectors of this spec and age the resolution ranges from nHD (640x360) (worst) to DCI 4K (4096 x 2160) (best).
Quite Low Horizontal Synchronization (max)
The average horizontal synchronization (max) of similar spec projectors that have been on the market for a comparable time to the DS346I is 91kHz. The Optoma DS346I has a quite low horizontal synchronization (max) (only 91.1 kilohertz) compared to most of the other comparable spec projectors that have been on the market for around the same time as the DS346I.
Very Low RMS Rated Power
With an RMS rated power of only 2 Watts, the Optoma DS346I has one of the lower RMS rated powers amongst 18000:1 contrast ratio data projectors of this age. The RMS rated powers of 18000:1 contrast ratio data projectors that have been around for a similar time to the DS346I range from 2W to 16W.
+2 More reasons against
Very Low Vertical Synchronization (max)
The Optoma DS346I has one of the lower vertical synchronization (max)s (only 0.085 kilohertz) amongst projectors of this age. The vertical synchronization (max)s of projectors that have been available for a similar time to the DS346I range from 0.085kHz to 120kHz, and the average vertical synchronization (max) is 50kHz.
2 Other reasons to consider the Optoma DS346I
Released Over a Year Ago
Optoma released the DS346I over a year ago.
Average Projector Brightness
The Optoma DS346I has a pretty average projector brightness (3,000 ANSI lumens) compared to most of the other multimedia projectors of a comparable type and age to the DS346I.
It may also be worth considering one of the alternative 3,000 ANSI lumens brightness projectors currently available including the Optoma DX342[plb_2985138_price] which has better reviews.

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.
