Cheap design and noise monitor: Disappointment ACER AL2623W experience
 
From this March, I start to research LCD monitors and want to have a new
one,
I have the impressive experienced with INX 19JS LCD which is SHARP OEM
version 3 more years ago.
Same shapes with different logo, the other design and functions are all the
same, purchased price is about 780USD.
Unfortunately this company change their warranty from 3 years become 1
year in private without any notice.
When this serious problem exploded on forums, many Taiwan retail shops
start to decline their products, this brand suddenly disappeared within 2~3
months.
The only lucky thing I had is the LCD made by SHARP with great lifetime
quality even I lost the warranty.
That LCD also have great display quality with SHARP ASV panel, I had never
seen any better LCD got same true color and gray level in the normal LCD
market.
After my researched, the first one I bought is DELL 2407WFP.
Comes with SAMSUNG S-PVA panel, the industrial design and function is
outstanding, the color is also good after I corrected it.
Below is the non-corrected INX 19JS LCD compare with corrected bright and
RGB parameter DELL2407 (The difference will become smaller after use the
color correct tools)


After few days, Iím not satisfied with DELL 2407WFP default quality and try
to have other batter IPS panel LCD.
So I start to study other products and panels info, the MITUBISHI RDT261WH
did have great recommend and very popular in Japan with 1000USD street
price.
NEC also have same 25.5 inch IPS panel LCD but higher price about 1150USD.
Because Taiwan market size is smaller, most popular LCD is about 22 inch
with cheap TN panel. The better choice besides TN panel was few brands on
24 inch and DELL 27 inch with SAMSUNG PVA panel LCD.


I wait for more then a month, just want to have FEELER 25.5 inch LCD with
IPS panel.
There were demo machine on retail shop in March, the same shape with the
MITUBISHI one, only reduce 1 DVI become 1 D-SUB and 1 DVI design, also
change the OSD style.
But the bad news in April, that FEELER LCD still not sure the launch time in
Taiwan, and I saw someone posted the ACER AL2623W LCD in forum.
Than I sold out the DELL 2407WFP and purchase one ACER AL2623W with 800
USD.
The price is good, I got them in mid April, heard that this is the first lot with
few quantity.
Take the first look with packing, the BOX is huge because the stand base
connected with LCD.


LCD connects cables. The slimmest cable Iíve ever seen in my life, not even
close to catch up old 19 inch LCD cable quality.


The ACER AL2623W.


Plastic based design.


Look the back side, full of the holes with full plastic quality.



DVI/D-Sub/Audio input
This LCD have internal speaker.


Power input and bottom.


All the bottoms are under the panel, the speaker out put is also under the
panel.


Plastic shell base comes with metal.


The heat spread holes above the panel.
Too big hole size, we can even seen the internal IC part numbers.
You may also see the back light if lucky.
That will cause the dust problem that failure the circuits.



Very small up and down angle, thatís also the only movable part.



Syper2express color corrected.


Panel info
The first lot seems use LPL IPS panel.


Letís take a look on pros and cons on ACER AL2623W
Pros:
1.Cheaper then same level Japan LCD with 200USD more. But only few gape
with FEELER.
2.Use IPS panel, got better recommends compare with SAMSUNG PVA panel.
3.Many OSD adjust functions, contrast, bright and RGB adjust.

Cons:
1.All solid plastic design with metal spray paint only.
2.Built-In speaker with only volume adjust, can not turn off.
3.Too many big heat spread holes to let you see through the IC parts, when
the monitor power on, there is some electricity noise from above holes of the
LCD.
4.Power on too slow, that may take 4~5 seconds, jump out ACER and turn to
the display status.
5.OSD function is below the panel, inconvenience, bottom tag is not clear
enough, no one bottom switch the input.
6.3 year warranty but no delivering service.
7.Same cheap plastic design with low cost 19 inch to 22 inch. Far from high
value shapes.

Letís discuss about the noise problem,
I did use many LCD monitors in my career, include many type of
17/19/22/24/27 inch, this is the first time I heard about some electric noise,
there were some ACER AL2623W users also heard about the noise on forums
in Japan, and they called that exhaust noise.
As I know, LCD monitors should not have noise inside, am I right?
The shopping forum in Japan
There also had some users bought this LCD and share their experience,
some one also mentioned their ACER AL2623W have same noise too.

Can you really go back to cheap plastic after having expierenced the 2707 or does it increase the risk of beinng depressed every minute you look at the plastic :-p?

jmke 26th June 2007 17:33

I couldn't care less how of what housing is made of, if the screen has high definition, clear colors, no ghosting and is good for movies, I won't complain:)

Sidney 26th June 2007 17:35

I thought LCD Color analyser costs a lot more.

A grat screen needs a great housing.

jmke 26th June 2007 18:29

not at all; there is no "need" for that at all; sure it looks look when the screen is turned off, but when on, the housing should be designed to be not noticeable.
