16 Reasons For
One Industry Award
This 3000:1 contrast ratio projector was given an "Editor's Choice" award by PC Mag who said that this multimedia projector was terrific.
Good Expert Reviews
Two experts from sites including PC Mag and hardwarezone.com.sg have rated this multimedia projector on average 83 out of 100.
Running Costs Are Low
The M311 has an average running cost of only £79 over 1 year based on average usage levels and energy prices, which is in the cheapest 14% of all 92 3000:1 contrast ratio projectors that were released more than two years ago.
On average NEC 3000:1 contrast ratio projectors have good ratings as do all data projectors produced by NEC.
Good Product Quality
One NEC M311 owner reckoned that the product was good quality. Pcmag.com said in their review of the NEC M311 on expert website PC Mag “Better video quality than most data projectors”.
Easy to Use
One NEC M311 reviewer reckoned that it was easy to use. Three years ago Hardwarezone.com.sg said “It's neither possible nor practical to have a darkened room” in their review.
+11 More reasons for
One customer who reviewed this projector reckoned that it was good in terms of connectivity. Three years ago Projectorreviews.com mentioned “Plenty of connectivity options, including dual VGA” in their review.
Good Picture Quality
One NEC M311 owner who reviewed it considered that it had good picture quality. Projectorreviews.com said “Good data and video image quality”.
Has a Built-In Speaker
The NEC M311 has a built-in speaker. Most of the other projectors of this age and spec also have a built-in speaker.
It may also be worth also looking at one of the other projectors with a built-in speaker currently available including cheaper projectors such as the NEC VE281[plb_1473677_price], or the Sony VPL-DW127[plb_2512334_price].
1920 X 1080 (HD 1080) Graphics Resolution
The NEC M311 supports a maximum resolution of 1920 x 1080 (HD 1080). That's 8% more resolution than a 1600 x 1200 (UXGA) multimedia projector, which is the most common resolution supported by comparable spec projectors that have been on the market for more than two years. 1600 x 1200 (UXGA) is also supported by this projector. In addition, this data projector support graphics resolutions of 720 x 480, 720 x 576, 832 x 624, 1152 x 870, 1280 x 960, 1600 x 900, 1280 x 720 (HD 720), 1280 x 768 (WXGA), 1280 x 800 (WXGA), 1366 Ñ 768, 1400 x 1050 (SXGA+), 1440 x 900 (WXGA+), 1680 x 1050 (WSXGA+) and 640 x 480 (VGA) and 800 x 600 (SVGA). Across all 3000:1 contrast ratio projectors that were released around the same time as the M311 the resolution ranges from 640 x 480 (VGA) (worst) to 1920 x 1200 (WUXGA) (best).
WXGA (1280x800) Native Projector Resolution
This projector has a native projector resolution of WXGA (1280x800), which is the most commonly found native projector resolution on projectors of a comparable spec and age to it.
Three USB 2.0 Ports
The NEC M311 has more USB 2.0 ports than most of the projectors of a similar age and type to the M311. This data projector is a three USB 2.0 port data projector compared to most of the projectors that have been on the market for around the same time as the M311 which only have between one and two USB 2.0 ports.
Quite Long Service Life of Lamp in Economic Mode
The service life of lamp in economic mode of similar spec projectors that are a comparable age to the M311 range from 230h to 20,000h, and the average service life of lamp in economic mode is 5,800h. The NEC M311 has one of the longer service life of lamp in economic mode (8,000 hours) amongst projectors of this age.
Quite Long Lamp Service Life
Projectors of a similar age and type to the M311 have lamp service lives of between 1,500h and 30,000h, and the average lamp service life is 4,400h. At 5,000 hours, the NEC M311 has a fairly long lamp service life compared to most of the other 3000:1 contrast ratio projectors that have been around for around the same time as the M311.
100V AC Input Voltage
This data projector has a 100 - 240V AC input voltage, which is typical of many data projectors that are a comparable age to it.
Quite Quiet Noise Level
The average noise level of comparable spec projectors that have been available for a similar time to the M311 is 35dB. With a noise level of only 28 decibels, the NEC M311's noise level is one of the quietest amongst 3000:1 contrast ratio projectors that were released more than two years ago.
If you are not worried about having a louder noise level then you might want to look at the NEC VE281[plb_1473677_price] (35dB) which is also cheaper.
4 Reasons Against
Does Not Support 3D Image Projection
The NEC M311 does not support 3D image projection, although it is worth noting that most of the other 3000:1 contrast ratio projectors that are a similar age to the M311 also do not support 3D image projection.
Does Not Support Full HD Projection
Most projectors that have been on the market for around the same time as the M311 do not support Full HD projection. The NEC M311 is no exception to this as it too does not support Full HD projection.
Does Not Support WiFi Connectivity
Most similar spec data projectors that have been available for more than two years do not support WiFi connectivity. The NEC M311 is no exception to this as it too does not support WiFi connectivity.
Quite Dim Projector Brightness
The dimmest projector brightness of multimedia projectors of a comparable spec and age to the M311 is 100 ANSI lumens, the brightest is 8,000 ANSI lumens, and the average projector brightness is 3,500 ANSI lumens. With a projector brightness of only 2,325 ANSI lumens, the NEC M311's projector brightness is one of the dimmest amongst 3000:1 contrast ratio projectors that have been available for a similar time to the M311.
If this data projector projector brightness is too dim for you then you might want to look at the Sony VPL-DW127[plb_2512334_price] (2,600 ANSI lumens and cheaper).

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 NEC M311uses then please let us know by entering those figures in the boxes above.
Running this projector over 5 years will generate 0.39 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 11 tree seedlings and grow them for 10 years.
