! Do I need a different video card?
Posted by Gabriel Rapture on August 27th, 2006


I'm going to purchase this monitor in a few days. It is a Viewsonic
VX2025.

Right now i'm using a Dell XPS T 600 mhz with an LG Studioworks 995E
CRT monitor. The monitor worked fine for seven years. Then last week
it popped and then lost some of it's brightness. It is also doing some
other weird things. So I figured that was my hint that it is time to
buy another.

My question is will my current video card power this new flat panel
LCD monitor? Or will I need to buy a brand new video card?

If I need to buy, which is the best?

I'm pretty sure I am the only person in the world who will say
this, but IMO CRT monitors will continue to be better than ANY
LCD monitor for *some* time, not to mention a lot cheaper. Also,
if anything goes wrong with a single LCD pixel, you're fucked.
And most manufacturers warranties allow up to 30 or so dead
pixels as "normal". HAH.

Also, the "less power used" is a VAST exaggeration. They just
look cool - if that's what matters to you.

I don't know if you can even get a Sony CRT monitor anymore. I
have one that's 9 years old and it looks as good as the day I
got it. Judging by Sony TV's I've owned, it may work fine for
another ten years.

If it dies, I will look for a used Sony CRT that has less years
on it than mine. Otherwise, Samsung SyncMasters and certain
Philips models are pretty good. Hopefully, SOME brand of CRT
monitors will still be on the market whenever I am faced with
this problem.

Also, if the image on your LG was good until it just started
screwing up, it may simply be a minor component or board (there
are a bunch of small PC boards in every CRT) that just died. It
may be quite simple to repair. If the tube is gone, that's
another matter.

(I realize that I not only did not come even close to answering
your question and also that I MAY have confused you with what I
said. Sorry.)

You will have to verify if the card can meet the standard for the new LCD
monitor. LCD monitors must work in their native mode to give optimum quality
of image. Most LCD monitors work in 1024 X 768 in the smaller sizes. In the
medium sizes they work in the 1080 X 1024. Most descent display cards going
back about 3 to 5 years can handle these resolutions.

Another thing to check in to about your display card, is that it can handle
16 bits colour at the minimum in the resolution you require.

There are many rumours and speculations about LCD monitor dead pixel
policies. The different manufactures each have their own policies. There is
a standard set by the ISO committee that the manufactures must follow at the
very minimum. ISO 13406-2.

The link below explains the criteria for dead pixels. Most manufactures will
exchange the monitor if there are more than 5 defective pixels in total, or
if there are more than one dead pixel located closer than 10% distance from
each other in relation of the monitor screen size.

http://www.fujitsu-siemens.co.uk/rl/...PixelError.htm

With LCD monitors, there is no UV radiation, or flicker which causes eye
sore, and may cause headaches for some people. There is no strong
electromagnetic or any detectable X-Ray radiation emissions. Power
consumption is reduced by 60% to 80% in the operation mode. The lifespan of
the LCD monitor is greater than the CRT type.

In business environments where LCD displays are used, they found that the
frequency of sick leave was reduced. They found that people were feeling
less tired and stressed when working on their computers. In businesses where
they are using many computer terminals and changed over to LCD displays,
they found a sizeable reduction in their cost of power usage.

As for CRT monitors, the parts that go in to the tubes are no longer being
manufactured. The discounted monitors that you see on the market today, are
being built with parts inventories that are left. Many of the distributors
and stores are no longer handling CRT monitors.

Consumer LCD panels are Class II. If you want to pay out for an expensive
professional type LCD panel, you can go to a Class I, which is a zero dead
pixel monitor. There are some manufactures who are offering a zero dead
pixel policy, but there are other defects that they do not specify, such as
shading and contrast errors.

__________________________________________________ ______________________
To regulate the acceptability of defects and to protect the end user, ISO
have created a standard for manufacturers to follow. ISO 13406-2 recommends
how many defaults are acceptable in a display before it should be replaced,
within the terms & conditions of warranty.
All reputable manufacturers conform to and support the ISO 13406-2
standard.

The table below shows the allowable number of malfunctioning pixels that
are acceptable, depending on the native resolution of the LCD and allowing
for 2 malfunctioning pixels per million pixels.
Native resolution No. of pixels No. of million pixels Acceptable
defects
1024 x 768 786,432 0.8 2
1280 x 1024 1,310,720 1.3 3
1600 x 1200 1,920,200 1.9 4
2048 x 1536 3,145,728 3.1 6

The table below shows the allowable number of malfunctioning sub-pixels
that are acceptable, depending on the native resolution of the LCD and
allowing for 5 malfunctioning sub-pixels per million pixels.
Native resolution No. of pixels No. of million pixels Acceptable
defects
1024 x768 786,432 0.8 4
1280 x 1024 1,310,720 1.3 7
1600 x 1200 1,920,200 1.9 10
2048 x 1536 3,145,728 3.1 16

The table below shows the allowable number of malfunctioning sub-pixels
that are acceptable within a 5 x 5 block of pixels, depending on the native
resolution and allowing for 2 malfunctioning sub-pixels within a 5 x 5
block, per million pixels.
Native resolution No. of pixels No. of million pixels Acceptable
defects
1024 x 768 786,432 0.8 2
1280 x 1024 1,310,720 1.3 3
1600 x 1200 1,920,200 1.9 4
2048 x 1536 3,145,728 3.1 6

The above is relevant to Class II LCD panels.

I think that before answering, you should have done some research in to LCD
displays. A typical CRT monitor uses about 140 to 170 Watts. A typical LCD
monitor uses about 30 to 50 Watts. This is dramatic, especially when a
company is using hundreds of computers. They can almost save the cost of the
LCD monitor purchases over the first year just on power consumption alone!

In companies where they changed over to LCD displays, there was a noticeable
decrease of sick leave. There is less eye sore, stress, and fatigue. There
are also many improved environmental issues with the disposal of LCD
displays compared to CRT displays when it comes time to change them.
Eventually, everything will wear out and have to be replaced.

As for the defective pixel policy, reputable manufactures will exchange the
monitor if there are more than 4 or 5 defective pixels in total. Each of the
manufactures have their own defective pixel policies, which usually exceed
the required ISO standards.

Many of the manufactures will without question, unofficially exchange the
monitor for any amount of dead pixels just to keep the customer happy.

Right. Even if that was actually the case, it would be a 60 W
lighbulb versus 2 or 3 60W lightbulbs. BIG difference. It's not
like using three 1500 W floodlights to light your room, you
know.

As is the individual who OP'd. Sigh.

Yes, and companies who use hundreds (or 1000's of monitors)
REALLY need to watch every penny, especially lest it go to a
pension for a worker whose job is now being done by someone in
Asia for 1/10 the cost.

Anyway, the "savings" kick in after 3-5 years by which half the
LCD's will be garbage.

Only ONE manufacturer (the most expensive one) allows for
consumer replacement of the backlight. Ever check into how much
those cost? And the labor?

This may be true, although my experience is exactly the
opposite. But it also depends on how important image quality is
to you. I see you have not mentioned how it is IMPOSSIBLE for an
LCD to produce a pure black.

Yes, THAT will save the world from going to hell in a
handbasket.

First 100% true statement.

Ever tried to have this done?

You know, I got that Dell 24 inch LCD last year and I immediately
noticed within the first hour of using it that my eyes were going cross
eyed trying to focus on it. I would get tired eyes very easily.
Fortunately, for a long time I was only using it for short periods,
while at work I had a pretty old Sony Triniton 20" at 75hz that though
was not anywhere near as "crisp" as my new LCD at home...didn't really
seem to bother my eyes at all...even after long hours of working.

Well for the past 8 months I've been working from home every day, long
hours on the LCD. And now I'm having severe eye problems..it has
effected my distance vision as well as everything is blurry, but eye
tests show very little official problems with my eyes according to the
eye doctor. Yet everything is blurry and hard to focus. he says I
have eye fatique and need reading glasses (I just turned 40). Ok. But
I don't read except on computers which reading glasses are not really
designed for (wrong distance).

In any case, I actually think there is some combination of LCD and
aging eyes at play here for me. I never had any eye problems before
getting this monitor. My vision has always been better than 20/20.
Since getting the monitor my vision has been getting blurrier and
blurrier. Yes, the display lucks totally amazing. Crystal clear.
And yes, I use DVI Matrox P650 in 1920x1600 mode. The native timing is
60hz and can't change it. I guess this is normal for LCD's.

In any case, does anyone have any better theories for why these LCD's
are causing eye strain for some of us and not for others...even though
they do look amazingly sharp and even though the refresh rate is
supposedly inconsequential? I noticed this eye strain immediately the
first time I used this monitor, but now my eyes are getting severely
strained (I hope no permanently) and i'm thinking about going back to a
fuzzy CRT just for this reason alone.

Any other thoughts?
