8 Reasons For
Acer Projectors Have Good Reviews
We checked the reviews from users and experts of hundreds of multimedia projectors to determine an average rating for each multimedia projector brand. On average Acer multimedia projectors have good ratings from owners and experts.
The Acer K137i supports 3D. Most of the other data projectors of this type and age do not support 3D.
Supports Full HD
The Acer K137i supports full HD. Most of the other battery powered projectors that have been on the market for more than a year do not support full HD.
Has a Built-In Speaker(s)
The Acer K137i has a built-in speaker(s), as do most of the other multimedia projectors of a comparable type and age to the K137i.
It may also be worth considering one of the other projectors with a built-in speaker(s) currently available including the Asus P3B[plb_3130845_price] which has better reviews; or the Panasonic PT-LW362[plb_3399991_price], or the Philips PPX4935[plb_3021717_price] which is cheaper.
Fairly Long Service Life of Lamp (economic Mode)
The Acer K137i has one of the longer service life of lamp (economic mode)s (30,000 hours) amongst multimedia projectors of this age. Multimedia projectors of this spec and age have service life of lamp (economic mode)s of between 800h and 75,000h.
Two Number of Built-In Speakerss
The Acer K137i has more number of built-in speakerss than most of the projectors that were launched more than a year ago. Most of the multimedia projectors that are a comparable age to the K137i only have one number of built-in speakers, however this projector has two number of built-in speakerss.
+3 More reasons for
Supports One Image Formats Supported
The Acer K137i has a greater number of supported image formats than most data projectors that are a comparable age to it. The most commonly supported image formats supported is JPG, but this image formats supported is not supported by this data projector. The image formats supporteds BMP,JPG,BMP,JPG are also supported by this Acer projector.
Very Quiet Noise Level (economic Mode)
Across all the projectors that were launched more than a year ago the noise level (economic mode)s range from 26dB to 40dB, and the average noise level (economic mode) is 32dB. With a noise level (economic mode) of only 29 decibels, the Acer K137i has a fairly quiet noise level (economic mode) compared to most of the other projectors that are a comparable age to the K137i.
2 Reasons Against
Does Not Support Wi-Fi
Like most of the other battery powered projectors that have been available for a comparable time to the K137i, the Acer K137i does not support wi-Fi.
We compared this data projector to all the other multimedia projectors with a wi-Fi and we think the Philips PPX4935[plb_3021717_price] is also worth considering.
Very Low Vertical Synchronization (max)
With a vertical synchronization (max) of only 0.12 kilohertz, the Acer K137i has a fairly low vertical synchronization (max) compared to most of the other multimedia projectors that were released more than a year ago. The lowest vertical synchronization (max) of multimedia projectors that have been on the market for a similar time to the K137i is 0.085kHz, the highest is 120kHz, and the average vertical synchronization (max) is 58kHz.
5 Other reasons to consider the Acer K137i
OK Running Costs
The K137i is typical compared to the other 6 projectors of this spec and age that we have looked at for running costs. Based on average energy prices, we estimate the K137i will cost £25 over 1 year to run.
Released Over a Year Ago
It was over a year ago when Acer released the K137i.
WXGA (1280x800) Projector Native Resolution
This multimedia projector has a projector native resolution of WXGA (1280x800), which is the most commonly found projector native resolution on similar spec projectors that are a comparable age to it.
