I long ago adopted this Acer X223W monitor for use in my shop.
It ran on my main computer for a year, My main computer is:
Motherboard - Intel DP55KG
CPU - Intel Core i7 K 875 @ 2.93Ghz
Memory - 8 Gb (3.49 Gb in XP)
Video - NVidia GeForce 210 (512)
Dual-boot Windows 7 Premium 64 bit, XP Pro SP3.
I got something better and retired the Acer to my shop. My problem now is
that I am occassionly running into situations where I get an "input not
supported" message. Some of them will work in safe mode but not in normal
mode. Right now I have a Sony Vaio that will work in normal mode but will
fail in safe mode.. In XP when you run safe mode and get all that text, it
gets down to mup.sys the screen goes black and up pops "input not
supported". So I have an old crt Viewsonic that measures 16" diagonally and
weighs about a ton that has never failed to handle any kind of resolution.
However it doesn't do DVI,
I want to buy me a reasonable sized flat screen monitor that will handle
anything you throw at it. I'm sure I'll be able to sell the Acer to someone
who it works for,
So does anyone have a monitor to recommend that is very versatile and will
handle most any kind of resolution?, This Acer is 22" but I would settle
for less if that's what it takes.
That tonner has got to go. A high school senior carried it up my steps to
trade on a flat screen. I'd happily give it to Good Will if I could get
anyone to get it there for me... :-)

There is a suggestion in this thread, to use some "VGA Mode" option
in Safe Mode.
I think in general, it's pretty hard to guarantee a monitor
will take any old crap thrown at it. For example, if the video
adapter is outputting a signal with a 150Hz refresh rate,
I doubt there is any monitor which will be really happy about
that.
I tried looking for a device which could measure the signal
parameters on the VGA connector (so you can tell how the signal
is broken), but haven't found a device yet to do that. You
can check with an oscilloscope, look at HSYNC and VSYNC,
but it would be nicer to have a dedicated box to do it.
You could look for a popular model on Newegg, to get some
idea how good or bad they can be.
VGA output can go up to 2048, so it's still possible to put out
a signal past the range of that monitor. The refresh could be
set to 150Hz, which would be past any monitor I've heard of.
(Some of the 3D capable ones, go to 120Hz.) And some people may
have set their computer to put out 1360 or 1368 (attempting to reach
1366 native), and I don't know how that monitor would respond to
such an input. So all I know for sure, is that Asus monitor has 1440x900
(which I use on my other computer), whereas your Acer didn't have that.
*******
As for the CRT, see if your city has a "Take It Back" program, for
recycling electronics. See what pickup options they offer. I doubt
you'll get anyone to lift it out of the house for you, but you never
know. Old CRTs really shouldn't go to the dump - they're supposed to
be deflected to recyclers first. And preferably, not end up on a
container ship, sent to India or China, to be "cooked down" for the
metals.

I am going with a Viewsonic VA2231wm-LED 22" Class Widescreen LED Backlit
Monitor - 1920 x 1080, 16:9, 10000000:1 Dynamic, 1000:1 Native, 5ms, DVI,
VGA, Energy Star. (more information than I understand)
All I have now are three Acers, all 22" but with different model numbers.
1680 X 1050 is the high resolution on all of them. The Viewsonic supports
1920 X 1080 so I will probably use that one for my personal computer and
try this one (Acer AL2216W) in the shop.
I don't seem to be able to find a list of supported resolutions for *any*
of the Acers or even the Viewsonic. All the specs I can find just show the
maximum resolution. Like you did for that Asus.
As I pointed out in my original post, the Sony Vaio will display its preset
resolution of 1280 X 1024 in normal mode. The max allowable setting is 1600
X 1200. It also displays the BIOS setup screen OK. But Safe Mode gives me
the "input not supported" message. You would think that safe mode
resolutions would be supported by most any monitor. The Acer actually
supports 1680 X 1050 but the Sony's adapter obviously doesn't handle that.
We have a fire department in a neighboring larger community that takes in
old computers and monitors a couple times a year for free. I've used their
services before but if a monitor is still functional I can usually find
someone to give it to.
As always, thanks for your detailed input. Most of the time, you are a bit
over my head, but I use the bits and pieces that I understand!.

Now, would it say "out of range" if you selected 1152x864 on the
video card ? I don't know the answer to that. The other monitor I
was looking at, mentioned it had room for up to nine custom
resolutions, meaning if you send it an oddball, it's supposed to
remember that for next time. The reason the monitor memorizes the
resolution, is so it can record your vertical and horizontal
offset settings. (On my monitor, I can push the image left-right
or up-down, and next time, when presented with the same resolution
and refresh, the monitor is supposed to look up the left-right and
up-down offsets it recorded from the last time. That's handy, if the
computer has a habit of sending an off-center image.)
In Linux land, the default video driver sends an off-center image,
while if you load the custom Nvidia driver, it's spot on perfect
(no offset needed). And those are examples of where some monitor
tuning may be necessary (depending on which video driver you
happen to have loaded). Having the monitor memorize the centering
adjustments, is so you don't have to do it over and over again.
Of course, if the video driver has a good control panel, you can
also fiddle with it there. It's much like audio, where your equipment
can have several volume controls :-) And it's your job to
figure out which one got set to zero :-)
And if you run into situations where you need custom settings,
there is always Powerstrip from entechtaiwan.com . If you wanted
to test how your new monitor responds to oddball resolution settings,
give this program a try in "trial" mode. This is mainly good for desktop
systems, with things like Nvidia or ATI video cards.

No. I got the monitor today. When I read your post, I slid the slider
just to see if 1152x864 would be there. It was. So I tried it and it
worked OK. When I went back to 1920x1080 it had screwed up my icons, of
course, but I had the foresight to save the layout before I experimented.
This one went on my main computer. I love it. Nice crisp resoltion and
bright colors. The Acer I had here before only went up to 1680x1050. The
only thing I *don't* like that the aspect ratio. Both monitors are 22"
monitors. The Acer was 18-3/4" X 11-3/4".
The ViewSonic is only 18-3/4" X 10-1/2".
Come to think of it, that kind of sucks. Higher resolution, smaller
screen.
Oh wait! The more I look at it the worse it gets. There is a line all the
way across the top of the screen. I have called ViewSonic and described
it to them. They agree that it is defective. Tiger Direct has already
sent me a return label and it is packed up ready to go back.
So much for *that* review!

Interesting. Most of the time, when there's a defect, it's a vertical line.
I'll have to keep this in mind, the next time a horizontal "bright line"
report shows up. With the vertical lines, on some brands of (mostly defective)
monitors, you see a couple vertical lines one day, twenty lines the next day,
and then whole patches of vertical lines on the third day. Which is a
fabrication issue of some sort, with the panel, or with the contact
between the panel and whatever holds the driver chips. The driver chips
themselves are unlikely to fail that way.
If you look at this diagram, showing the thin film transistors in the panel,
feeding the pixels, there should tend to be a preferred orientation for
the defects. A bright line, would come from the voltage on one of the
lines staying at a fixed voltage, as the other dimension scans and
charges the pixels. So bright lines should form in one preferred direction.
Compared to a regular monitor, this diagram may have to be rotated
90 degrees, to be consistent with the symptoms seen. (Turned this
way, I think you'd get "bright rows" rather than "bright columns".
A bright pixel, is a problem local to the pixel itself.
There are probably separate pixels for RGB, so one of the squares
in that picture, doesn't do all the colors by itself. They have
another picture on that Wikipedia page, of the separation of colors.
Good pages on how LCDs actually work, are hard to find. There are
plenty of articles about 2x16 displays (for instruments and the like),
but not a lot of good articles for the large panels.

I'm not going to take a time to make a webpage out of it, but the three
images I sent to ViewSonic can be viewed at....
Screen shots wouldn't work as they did NOT show the black line and echoed
image above it. So I did the best I could with my camera. The tech at
ViewSonic immediately recognized it as a defect.
I'll give them credit for that much. The manual that came with the
monitor listed their contact information, both email and phone. They
answered my email to which I had attached the above images and told me to
call them. I did and didn't have to wait over 2 or 3 minutes to talk to
the tech who then reviewed the pictures. Unusually good tech support. And
I could even understand him. :-)

That looks like a sync problem. Marginally more likely with VGA input
(RGBHV, Hsync and Vsync not on coax).
What I can't explain, is where the "mirror" effect is coming from.
That's just weird.

You're not going to believe this.
The replacement monitor came today.
Same damn thing!
The mirror effect? That's *exactly* what it is!
The actual LCD screen sits behind a black frame that protrudes
approximately 1/8 of an inch all the way around. It even had that stupid
film on it that you peel off to keep it shiny. And shine it does... just
like a mirror. I stuck a piece of duct tape about 6 inches long over it
at the top and the problem went away. Well, six inches of it anyway.
I notice that on my Acer screen, that area of the border is curved in
such a way as to prevent that reflection.
Poor design IMHO. Now all I need to do is figure a way to dull that
surface so it doesn't reflect.
I got a couple of second opinions on that thing before I sent it back.
Both agreed that the monitor was defective. Well, it wasn't, I guess, but
it's damn poor design!
