11 Reasons For
Running Costs Are Very Low
The CP-CX251N is in the cheapest 8% of all 13 2000:1 contrast ratio multimedia projectors that have been around for the last year that we have analysed for running costs. Based on typical energy prices and usage levels, we estimate the CP-CX251N will cost only £97 over 1 year to run.
Just Released Eight Months Ago
Being released just eight months ago, this data projector is likely to use better technology.
Price Drop of £41.41
The CP-CX251N has dropped in price by £41.41 in the last 8 days.
Supports Full HD Projection
Like most of the other latest similar spec projectors, the CP-CX251N supports Full HD projection.
Has a Built-In Speaker
The CP-CX251N has a built-in speaker. Most of the other 2000:1 contrast ratio multimedia projectors that were released in the last year also have a built-in speaker.
1400 X 1050 (SXGA+) Graphics Resolution
The CP-CX251N supports a maximum resolution of 1400 x 1050 (SXGA+). That's over four times the resolution of a 640 x 480 (VGA) projector, which is the most common resolution supported by data projectors that came out in the last 12 months. Across all multimedia projectors that have been available for around the same time as the CP-CX251N the worst resolution is 640 x 480 (VGA) and the best is 1920 x 1200 (WUXGA).
If the resolution of this data projector is too low for you then you might also want to look at the Epson EH-TW570 (£429.99) (1280 x 720 (HD 720 and higher rated) and higher rated), or the Vivitek Qumi Q6 (£326.72) (1280 x 800|1600 x 1200 (UXGA and higher rated) and higher rated).

Three VGA (D-Sub) Ports
The CP-CX251N is a three VGA (D-Sub) port data projector.
Quite Long Service Life of Lamp in Economic Mode
2000:1 contrast ratio multimedia projectors that have been available for around the same time as the CP-CX251N have service life of lamp in economic mode of between 3,500h and 20,000h, and the average service life of lamp in economic mode is 6,700h. With a service life of lamp in economic mode of 10,000 hours, the CP-CX251N has a quite long service life of lamp in economic mode compared to most of the other comparable spec multimedia projectors that have been available for a similar time to the CP-CX251N.
Very Long Lamp Service Life
At 5,000 hours, the Hitachi CP-CX251N has a very long lamp service life compared to most of the other similar spec projectors that came out in the last year. The shortest lamp service life of recently released similar spec data projectors is 1,500h, the longest is 5,000h, and the average lamp service life is 3,500h.
Very Quiet Noise Level in Economy Mode
At only 29 decibels, the CP-CX251N has a fairly quiet noise level in economy mode compared to most of the other 2000:1 contrast ratio multimedia projectors that have been available for a comparable time to the CP-CX251N. The average noise level in economy mode of 2000:1 contrast ratio multimedia projectors that were released around the same time as the CP-CX251N is 32dB, and the noise levels in economy mode range from 29dB to 37dB.
With a weight of only 3.4 kilograms, the CP-CX251N is one of the lighter new 2000:1 contrast ratio multimedia projectors amongst 2000:1 contrast ratio multimedia projectors of this age. New data projectors have weights of between 2.8kg and 13kg.
8 Reasons Against
Does Not Support WiFi Connectivity
Like most of the other latest 2000:1 contrast ratio multimedia projectors, the Hitachi CP-CX251N does not support WiFi connectivity.
Does Not Support 3D Image Projection
The CP-CX251N does not support 3D image projection. Most of the other data projectors that were launched in the last year also do not support 3D image projection.
Very Dim Projector Brightness
The dimmest projector brightness of 2000:1 contrast ratio multimedia projectors that were released in the last year is 2,500 ANSI lumens and the brightest is 8,000 ANSI lumens. The Hitachi CP-CX251N has one of the dimmer projector brightness (only 2,500 ANSI lumens) amongst comparable spec data projectors of this age.
Very Low RMS Rated Power
The RMS rated power of new comparable spec projectors range from 1W to 10W, and the average RMS rated power is 5.8W. At only 1 Watt, the CP-CX251N has a fairly low RMS rated power compared to most of the other new comparable spec projectors.
+5 More reasons against
Very Dim Brightness in Economy Mode
At only 1,675 ANSI lumen, the CP-CX251N has a quite dim brightness in economy mode compared to most of the other data projectors that were released in the last 12 months. The brightness in economy mode of newly released 2000:1 contrast ratio multimedia projectors range from 1,600 ANSI lumens to 6,400 ANSI lumens, and the average brightness in economy mode is 4,400 ANSI lumens.
Only 525i Video Mode
This multimedia projector supports a 480i|480p|525i|576i|625i|720p|1080i|1080p video mode, which is typical of many projectors that have been available for the last year.
Very Small Lamp Power
The Hitachi CP-CX251N has a quite small lamp power (only 225 Watts) compared to most of the other projectors that have been around for a comparable time to the CP-CX251N. The lamp power of 2000:1 contrast ratio multimedia projectors that have been available for a similar time to the CP-CX251N range from 220W to 400W, and the average lamp power is 320W.
Very Small Matrix Size
At only 0.63 inches, the CP-CX251N has a quite small matrix size compared to most of the other 2000:1 contrast ratio multimedia projectors that were released in the last year. The average matrix size of new 2000:1 contrast ratio multimedia projectors is 0.71", and the matrix sizes range from 0.63" to 0.79".

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 Hitachi CP-CX251Nuses then please let us know by entering those figures in the boxes above.
Running this projector over 5 years will generate 0.48 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 13 tree seedlings and grow them for 10 years.
