What is the maximum display resolution or the dot pixel of the LCD

I'm not sure how this is relevant, but at the moment I'm using
a laptop PC since I'm on a business trip (in Taiwan currently,
and oddly enough visiting LCD manufacturers, which is part
of what I do for a living). This one happens to be a 12.1"
XGA (1024 x 768), which would mean a resolution of
approx. 106 ppi. When in the office, I'm currently using a
19" SXGA (1280 x 1024) monitor, which would be about
86 ppi. I'm happy with it.

By "dot pixel," do you mean "dot pitch"?

Very interesting. I also use a 19" SXGA 1280x1024 LCD (a Dell
1907FP by Samsung) in my office and it is just horrible. The LCD I use
at home is a 17" SXGA 1280x1024 (Viewsonics VX700) and it is zillion
times better, none of the grainy look of the former. The difference
should be less than 19/17, but it is like night and day. One is silky
smooth and the other grainy. I start to think that it is not just the
..25mm vs .294 mm dot pitch difference, it may be due to the physical
structure of the pitch itself of different makes. One of those days I
will post pictures of comparison on the net to show the dramatic
difference (especially the visible grid) that might cause some grief
like mine.

In the mean time I probably will switch to a Viewsonics VX2025WM
20" LCD that has .26 mm dot pitch. The user rating on cnet.com is 8.8
for this monitor, comparing to a low 6.4 for the 1907FP. So that's a
good sign. I hope this one is as good as the VX700 I have at home.
Sorry to be so specific. After getting bit by something I have taken
for granted in the past, I need to be more specific to get a good
solution this time.

Thanks!

I just received a Dell 1907FP 19 inch LCD monitor. It has a very
visible grid matrix on the screen like a layer of nets that turns lines
into fuzzy dots. After a few hours of using it, my eyes is killing me.

I checked my previous Viewsonics VX700 17 inch LCD and there is no
such visible grid matrix on the screen. There are several possible
explanations:

1. The Dell 1907FP is using a grid matrix wire to provide current to
the pixels, the VX700 is using different technology which has less
visible grid matrix.

2. The VX700's dot pixel is only .25 mm and thus is less visible than
the 1907FP which has .294 mm dot pixel.

3. All of the above.

Anyone knows the reason why these two LCDs look so different?

(Most 19" LCD uses .294 mm dot pixels. Will a genric 20.1" LCD with
.255 mm dot pixel solve this problem?)

Are you certain ClearType is enabled for font smoothing? You should not
use ClearType on a CRT, but it can be almost mandatory to remove the
grittiness of fonts on an LCD. You can then optimize the settings of
ClearType with a little freeware program, ClearTweak. Highly recommended.

I've found that ClearType can be useful in rendering text on CRT
displays up to a point, though the effect is more subtle than on a
LCD. Another factor I've found annoying in LCD displays, especially
in the last few years, is the grainy anti-glare coating so often
used. It looks like I'm viewing the display through a sandstorm and
it's very hard to tune out.
