CRT & LCD Monitors
My very first monitor, in my computing world, was a 15 inch TV. Course, at that time
my mass storage facility was a cassette tape. Those were the days... At any rate, my most recent previous monitor was a
ViewSonic A90 CRT. I had it for a number of years and it went thru a couple of systems with me. Unfortunately, it
died. I was working on a database problem and I left my 'puter on 24hrs a day. I do this a lot so I won't forget, or
at least have a better chance of remembering, what I was doing. Even though the screen was
blanked, the monitor still had power. Well... it did. That's what died... no power. Some quick checks were made for
any obvious problems but nothing was found. I do not have the neccessary equipment
to trouble shoot it so, I called around about repairs. Out of the question. For the amount they were asking to
fix it, I could buy a brand new one ... which is what I did.
Now then, my 'intermediate' display was/is a 15 inch ViewSonic VA520 LCD. This was originally
purchased for my wife but she complained that it was to blurry. At the time I was only sitting at it for short time
periods and I didn't think it was that bad. At any rate, it has been my shop display
for some time now. It was ok for that. I never could find the response time for it,
but I'm sure that it was 25ms or greater. Quite a difference between the A90 and the VA520, besides the size. The LCD
picture was not as clear as the CRT. So, before I invested anything in a new display ... we needed to research.
For CRT's the selection would be easy, just get another ViewSonic A90 or whatever their,
ViewSonic's, newest comparable model is. However, for the LCD screens it is a little more involved. In order to
get a good screen you need to have a fast response time. It seems that 25ms or better is the magic number. At least
for the response time. The other number of importance is the dot pitch. The response time concerns blurriness and
the dot pitch concerns graininess... at least as far as I can see.
The CRT's win in the picture quality hands down. At least at this point in time, 30 Mar 05.
So, the two main reasons to move to an LCD display would be less Power Consumption and Smaller Footprint. Course, I
wonder a little on that last one. The main thing to decide on is which LCD monitor to get.
I have purchased a Sony SDM-HS95P/B. The Lord was with me on this one. He directed me to a very
good LCD. I stopped by the local 'puter store with my wife and whilst we were looking, one of the clerks pointed out this
monitor. My wife liked it right away. Not sure how much of that was cause of the sales person and how much was cause of
what was displayed. With the 0.294mm dot pitch, it is a little grainy. But it is not blurry, cause it is fast, 12ms response
time. Or am I just telling myself that cause of the speed. ViewSonic has a monitor that I was interested in also. It has
a 0.26mm dot pitch at 16ms response time. Now then, what is going to make the biggest difference, response time or pitch??
I'll have to go back to the store to figure that one out.
Whilst I am figuring out which way to go, you can look at some monitor information on the following
A. CRT Comparisons -
B. LCD Dot Pitch Selections
Alllrighty now. I went back to the 'puter store and the Lord was with me again. They had moved
the monitors around and there was only one, a Samsung, in between the Sony and ViewSonic monitors. My neighbor was with
me and he also was impressed with the Sony. With it mixed in among the other monitors it looked the clearest and the
best. I think it is mainly cause of the rich vibrant colors that it produces. On closer inspection I could not see a big
difference in the 'graininess' of the screens. I'm not sure where I got the 0.26mm figure for the ViewSonic cause I can't
find it again.?! So, if you are needing a new monitor and can afford it, I am recommending this Sony HS95P. I, and all my
relatives and friends like the colors. This is one of the best screens I have had, or seen. I have an R/C simulator (Real Flight G2) on this
PC and it performed well and looks great. Matter of fact, I was noticing how much realer the trees looked. I thank the Lord
for pointing this one out to me ... and for making me wait. This was a recent addition to my local Computer Store.
One closing comment: I have read some reviews that were rather detremental to this display device.
Their biggest complaints dealt with the frame and adjustability. Contrary to the complaints of others, there is some adjustability.
The 'case' has a tail that folds out for stability, just like a picture frame. It is not real loose and you can adjust the
straightness, or angle, of view. At least for proper ergonomic positioning. You can not tilt it down. So, if you are the type
of person who lays down while you are typing, this will not work for you. The height is another question. I think it is a little
on the low side. However, I have a power box and I set my monitor on top of it. The extra one and a half to two inches makes it
better for me. (And I just got a new one that is higher, over 4 and a half inches. A Logisys Extention Station described down
below at the end.)
As for rotatability, I don't see a problem. I can twist this 19 inch monitor just as easy, if not easier, as I
could my big 19 inch CRT. Just like a large picture, you can twist it for better viewing to someone else. And you don't have to
worry about the back end hitting something.
This Sony LCD monitor is just like everything else in this world. Some are gona love it and some are gona
hate it. However, I do believe that those who buy it and take time to get used to it will love it. Don't make the mistake that
I made and just look at all the specs. Just look at the monitor 'quality'... and enjoy.

Dead Pixel Policy
Please take note that all retail LCD monitors are governed by an international
standard regarding the fault tolerance of the pixels on the screen.
Due to the technology used it is known for LCD TFT monitors to develop
They can be in the form of pixels always being white “lit”(type 1),
always black “unlit”(type 2) or sub “red/blue/green” (type 3).
Under ISO 13406-2 the following types listed above are explained below and list
how many are required before the manufacturer is obliged to replace the item.
Please note these are cumulative so 2 dead type 2 pixel and 1 dead type 1 pixel would class as 3 dead pixels and be replaced.
- Type 1 - 3 faulty pixels
- Type 2 - 3 faulty pixels
- Type 3 - 6 faulty pixels
However some manufacturers use their own standards. For details of major manufacturers pixel polices please contact the manufacturer for details.

July 25th, 2016 Well, this 'was' my wife's monitor and because
I was claiming that I needed a wider monitor -and- she was tired of looking around hers to see the TV,
we swapped. I am, however, wondering IF it was such a good idea. Takes a little getting used to... but I think
in the long run I will be happier. A lot of the newer programs are almost requiring a Wide Screen. I suspect that
she may want hers back and then I will get one of my own. Till then...

Logisys PC extension station
For lack of a better place, at the moment, I am placing this here, since my
Monitor sits on top of it anyway,
has a good write-up on it. I will only repeat some of the info here.(
As it turns out ... none.)
They have a lot of pics so you might want to drop over to their site. Now then, I had some minor problems
with mine when I recieved it. Plugged it in, plugged in my System Components, hit the Master switch annnddd...
nothing. So, I disconnected everything, scoped out the wiring, found nothing, and then hooked it back up.
This time it worked!! And has been ever since. There have been a couple other minor probs. Once when I turned
off the Master Switch, the rest stayed on! I had had my System on for days. I actually don't remember what
was done to correct it, but it is working properly now. Well, I think so. May be producing a Motor Boat in
my speakers. Haven't done all the checking yet, but I will and hopefully will remember to put the results here.
I do need to say that it is a nice setup -but- even though it looks good, it seems like it was made in
someone's garage. The outlets on the back are not secure. You wouldn't want to plug and uplug into them
very much. Then there is the USB panel on the front. It is to be held in by two screws. One was missing and
the other is really to short and keeps falling out. -But- even with these, I still like it and I think it
is a good base for a tinkerer. A normal person may want to think twice.
I did make one modification to it. I drilled holes and installed to small
screws at the back for my monitor. I was worried about it sliding off. If you look at the Sony Monitors,
and some others that have the fold out stand, they can get jarred or accidentally pushed back and there
is nothing to stop them from crashing to the desk, UNLESS you are close to a wall, -OR- you put in stopper
screws like I did. These were little number 2 screws but they do the Job. JFYI.

Cleaning an LCD and an LCD Touch Screen
The following was borrowed/stolen from:
How to Clean Touch Screen Monitors at eHow.com
- Well, I must change the first step slightly since we may not be dealing with a monitor. These steps would
also apply to an LCD TV and a Touch Screen Remote and an iPod and... and... etc. In otherwords all LCD
screens. Now most, if not all, TV and Monitor screens have an On/Off button. However, most of the Remotes
do not have an On/Off button... for themselves. Therefore, we need to turn them over and remove the
battery. Afterwards you will be able to safely clean the screen. Just properly remove the power on whatever
device you are cleaning.
- Next, wet a soft, lint-free or microfiber cloth with distilled water. Wring out as much water as you can.
Make sure the cloth is damp but not wet. Wipe the screen in a gentle motion to remove dust, oil, or
fingerprint smudges off.
- Another option is to use a screen cleaner kit that includes antistatic wipes. You can buy this at
various electronic or online stores. Spray a little solution on a wipe then rub it gently across the
screen.(Wal-Mart sells it. I work there.)
- Finish cleaning the touch screen with a dry lint-free cloth to wipe away any excess moisture, then turn it
back on... or re-install the battery.
