9 Reasons For
Easy to Use
One customer who reviewed the Acer K138ST thought it was comfortable and easy to hold. Liveatpc.com mentioned “So, when Acer placed this short throw projector in my hands, I was excited to watch all my backlogged” .
Good Technical Features
One Acer K138ST owner reckoned that the product had good features. Amazon Customer mentioned in their Acer K138ST review on Amazon “Also, there are many fake features like Bluetooth”.
Acer Projectors Have Good Reviews
Projectors manufactured by Acer are some of the better projectors according to average user and expert reviews.
The Acer K138ST supports 3D, as do most of the other projectors of a similar age and spec to the K138ST.
Has a Built-In Speaker(s)
Like most of the other comparable spec projectors that are a similar age to the K138ST, the Acer K138ST has a built-in speaker(s).
We compared all the other projectors with a built-in speaker(s) to this multimedia projector and we think because of it's better review score, the LG PW600[plb_2860339_price] is also worth considering.
1920 X 1080 (HD 1080) Supported Graphics Resolutions
The highest resolution supported by the Acer K138ST is 1920 x 1080 (HD 1080). That's over six times the resolution of a 640 x 480 (VGA) multimedia projector, which is the most frequently found resolution supported by comparable spec projectors that are a similar age to the K138ST. Across all projectors of a comparable type and age to the K138ST the resolution ranges from 640 x 480 (VGA) to 4096 x 2160.
+4 More reasons for
Quite Long Service Life of Lamp (economic Mode)
The Acer K138ST has a very long service life of lamp (economic mode) (30,000 hours) compared to most of the other projectors that were released more than a year ago. The shortest service life of lamp (economic mode) of comparable spec multimedia projectors that are a similar age to the K138ST is 800h and the longest is 75,000h.
Very Quiet Noise Level (economic Mode)
The noise level (economic mode)s of projectors that came out more than a year ago range from 26dB to 40dB. At only 29 decibels, the Acer K138ST has a quite quiet noise level (economic mode) compared to most of the other comparable spec projectors that have been available for a similar time to the K138ST.
Quite Low Power Consumption (economy Mode)
With a power consumption (economy mode) of only 38 Watts, the Acer K138ST has one of the lowest power consumption (economy mode)s amongst similar spec projectors of this age. Across all the projectors of this age and type the power consumption (economy mode)s range from 38W to 890W, and the average power consumption (economy mode) is 360W.
7 Reasons Against
A Bit Expensive
One customer who reviewed this projector considered that it was not good value for money. Amazon Customer gave the product a score of 20 out of 100 and said on Amazon “The qualty of the picture is not really good regarding its high price” in their Acer K138ST review.
Only 100V AC Input Voltage
This projector has a 100 - 240V AC input voltage, which is the most commonly found AC input voltage on projectors that are a similar age to it.
Does Not Support Wi-Fi
Like most of the other data projectors of a comparable age and type to the K138ST, the Acer K138ST does not support wi-Fi.
Very Dim Projector Brightness
At only 800 ANSI lumens, the Acer K138ST has a fairly dim projector brightness compared to most of the other comparable spec projectors that have been on the market for a similar time to the K138ST. The dimmest projector brightness of projectors that came out around the same time as the K138ST is 300 ANSI lumens, the brightest is 11,000 ANSI lumens, and the average projector brightness is 3,900 ANSI lumens.
If this projector projector brightness is too dim for you then you might want to look at the Epson EH-TW5350[plb_3024662_price] (2,200 ANSI lumens), or the Acer H7550[plb_2821607_price] (3,000 ANSI lumens) which also has a higher rating.
+4 More reasons against
Very Low Horizontal Synchronization (max)
With a horizontal synchronization (max) of only 0.1 kilohertz, the Acer K138ST has a quite low horizontal synchronization (max) compared to most of the other projectors of this type and age. The lowest horizontal synchronization (max) of similar spec data projectors that have been around for around the same time as the K138ST is 0.1kHz, the highest is 110kHz, and the average horizontal synchronization (max) is 91kHz.
Quite Small Optical Zoom
The average optical zoom of multimedia projectors that came out around the same time as the K138ST is 1.3x, and the optical zooms range from 1x to 2x. The Acer K138ST has one of the smallest optical zooms (only 1 times zoom factor) amongst projectors of this age.
Very Short Service Life of Lamp
The service life of lamps of 100000:1 contrast ratio projectors that were released more than a year ago range from 20,000h to 30,000h, and the average service life of lamp is 28,000h. At only 20,000 hours, the Acer K138ST has a fairly short service life of lamp compared to most of the other data projectors that were released one year ago.
