Sometimes back, I bought a 22" Samsung wide screen
LCD monitor & eventually had a full refund from the
shop shortly after. Reason was the 1st panel has
a semi-bright dot & the replacement also has a semi-
So, it seemed until now, even reputed manufacturer
like Samsung does not offer zero bright dot warranty.
Phillips & LG does for restricted models but at a
huge price premium. So, I was looking at second hand
LCD monitors which I have the option of checking for
bright dot or dead pixel before payment. After a long
time of searching for good offer & the slow & draggy
bidding process... I finally gotten my second LCD
monitor, a Samsung 940T.
I was lucky enough, the seller sold me a 8bits LCD panel
for S$250 & he wasn't even interested in bargaining &
just want to get rid of his LCD at a price. Reason? He
has another 22" & 27" Samsung LCD monitor that he has yet
to open up & start using. And after checking thoroughly
for about 10~15 minutes, no bright dot or dead pixel.
The LCD is 1 year old & still has about 2 years warranty
Why I go back from 22" to 19" was that, 22" aspect ratio
is 16:10, when I watch TV series on my LCD (which is what
I do mostly), there is a bar on both side of the video.
If I force the video to 4:3, then all the characters will
look fatter. So, going back to 19" 4:3, I can watch TV
series in fullscreen without any black bars again.
Advantage of 19" over 17" LCD, both 19" & 17" LCD has the
same native resolution of 1280x1024. For any LCD, text
will appear the sharpest when it's displayed at it's native
resolution. For a 17" LCD, text will appear too small on a
1280x1024 resolution. I use my 17" at 1024x768 resolution,
which the text will be bigger, but it will not be as sharp
as 19". Of course, we all know 19" is bigger in size & will
be better for watching movies or TV series.
Something I think only LCD experts with sharp eyes can tell
about such 8 bits LCD panels. Accordingly, 8 bits LCD panels
produce true color or 16.7 million color. Normal 6 bits panels
uses software algorith to produce true color & the result is
16.2 million color. Due to that, 8 bits panels normal only can
do 20ms response time while 6 bits panels can do less than 10ms
easily. Personally, I can't tell yet how the color of this 8 bits
panel is nicer than my older 17" 6 bits panel, both from Samsung.
May be next time will have some of my LCD experts friend to show
I shall get second hand LCD panels only. Just to avoid the hassle
of getting bright dots or dark pixels in a brand new LCD monitor.
