13 Reasons For
Low Running Costs
The average 1 year running cost of the W331 is only £74 based on average energy prices, which makes it one of the cheaper to run recently released similar spec multimedia projectors.
Optoma Data Projectors Have Good Reviews
Optoma is one of the superior projector manufacturers according to average user and expert review score data that we have collected for all projectors.
Supports Full HD Projection
The Optoma W331 supports Full HD projection. Most of the other recently released data projectors do not support Full HD projection.
We compared all the other projectors which also support Full HD projection to this projector and we think the X115H[pl_3762955_price], or the P1285[pl_2934472_price] both from Acer or the Optoma DX349[plb_3434769_price] is also worth considering.
Supports 3D Image Projection
Like most of the other 20000:1 contrast ratio multimedia projectors that are a similar age to the W331, the Optoma W331 supports 3D image projection.
We compared all the other data projectors which also support 3D image projection to this data projector and we think the X115H[pl_3762955_price], or the P1285[pl_2934472_price] both from Acer or the Optoma DX349[plb_3434769_price] is also worth considering.
Has a Built-In Speaker
Like most of the other similar spec projectors that were launched in the last year, the Optoma W331 has a built-in speaker.
We think you might also be interested in alternative multimedia projectors which also have a built-in speaker including the X115H[pl_3762955_price], or the P1285[pl_2934472_price] both from Acer or the Optoma DX349[plb_3434769_price].
1600 X 1200 (UXGA) Graphics Resolution
The Optoma W331 supports a maximum resolution of 1600 x 1200 (UXGA). That's 17% less resolution than the most common graphics resolution of 1920 x 1200 (WUXGA). In addition, this Optoma projector support graphics resolutions of 640 x 480 (VGA), 800 x 600 (SVGA), 1024 x 768 (XGA), 1280 x 1024 (SXGA), 1280 x 768 (WXGA) and 1280 x 800 (WXGA) and 1360 x 768 (WXGA). The best resolution of all comparable spec data projectors that were released in the last year is 1920 x 1200 (WUXGA) and the worst is 640 x 480 (VGA).
+8 More reasons for
Two HDMI Ports
The Optoma W331 is a two HDMI port projector.
Fairly Long Lamp Service Life
At 6,000 hours, the Optoma W331 has a quite long lamp service life compared to most of the other recently released 20000:1 contrast ratio multimedia projectors. The lamp service lives of new 20000:1 contrast ratio multimedia projectors range from 3,000h to 20,000h.
Two VGA (D-Sub) Ports
The Optoma W331 is a two VGA (D-Sub) port projector. Most of the other 20000:1 contrast ratio multimedia projectors that have been available for the last year have between one and three VGA (D-Sub) ports.
Quite Quiet Noise Level
The noise levels of 20000:1 contrast ratio multimedia projectors that have been available for a comparable time to the W331 range from 22dB to 37dB. The Optoma W331 has one of the quieter noise levels (only 29 decibels) amongst 20000:1 contrast ratio multimedia projectors of this age.
If you would consider a projector with a louder noise level then you might want to look at the Acer P1285[plb_2934472_price] (26dB).
Quite Low Power Consumption During PowerSave
The lowest power consumption during PowerSave of 20000:1 contrast ratio multimedia projectors that were launched around the same time as the W331 is 80W and the highest is 370W. At only 187 Watts, the Optoma W331 has a fairly low power consumption during PowerSave compared to most of the other 20000:1 contrast ratio multimedia projectors that are a comparable age to the W331.
Very Low Power Consumption in Economy Mode
The power consumption in economy mode of comparable spec projectors that were released in the last 12 months range from 170W to 370W, and the average power consumption in economy mode is 230W. With a power consumption in economy mode of only 190 Watts, the Optoma W331 has one of the lower power consumption in economy mode amongst similar spec data projectors of this age.
With a weight of only 2.2 kilograms, the Optoma W331 is one of the lighter similar spec multimedia projectors that are a comparable age to the W331 amongst multimedia projectors of this age. Across all the recently released 20000:1 contrast ratio multimedia projectors the weights range from 110g to 40kg, and the average weight is 3.7kg.
3 Reasons Against
Does Not Support WiFi Connectivity
Most multimedia projectors that were released in the last 12 months do not support WiFi connectivity. The Optoma W331 is no exception to this as it too does not support WiFi connectivity.
Very Small Lamp Power
Across all the 20000:1 contrast ratio multimedia projectors that are a similar age to the W331 the lamp power range from 190W to 370W, and the average lamp power is 220W. With a lamp power of only 195 Watts, the Optoma W331 has a fairly small lamp power compared to most of the other new similar spec multimedia projectors.
Very Low RMS Rated Power
The Optoma W331 has one of the lower RMS rated power (only 2 Watts) amongst 20000:1 contrast ratio multimedia projectors of this age. The average RMS rated power of comparable spec projectors that are a similar age to the W331 is 7.6W.

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 W331uses then please let us know by entering those figures in the boxes above.
Running this projector over 5 years will generate 0.37 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 10 tree seedlings and grow them for 10 years.
