Anyone know of a hack to force monitor resolution and refresh rate to stick after cloning an image?

For me, I have two systems using the one monitor by KVM. I
prefer that they be at the same resolution. My XP system is at what
it is because I like it and it is also standard for an app I maintain.

The way I see it, your single monitor has a single native resolution
and both systems should be running at THAT resolution, but different
strokes for different folks.

Well, older eyes, too. I would rather use a lower resolution and
be comfortable using it even if it shows less than to be squinting at
a higher resolution. A YMMV issue to be sure.

In related news, my taskbar is at the top.

Agreed, but when you use a projector, the driver on your computer should
automagically select the projector's resolution. Leastways, it does
here. ;-)

On a proper computer monitor (display device intended for usage with computers),
there is a serial clock with data interface for reading out the monitor EDID.

Projection devices, have cabling for RGBHV, but lack EDID serial clock and data.
And that means, the computer has no way to "query" the monitor, and get
resolution data as part of Plug and Play. With that info missing, a video
driver may limit resolution choices to 1024x768 or lower.

By using an EDID box with your projector, you can "fake" the Plug and Play
information, and then you no longer run the risk of the computer using
some random (and bad) resolution choice.

This is an example of a box that stores EDID information, for later playback
to a computer. Using this, you can convince the computer, that the projector
has specific characteristics. You connect a regular monitor to the "input"
connector, and the box makes a copy of the EDID. The box is then connected
in-line with the projector, to provide the EDID info missing from the
projector electrical interface. Presumably this particular box, is DVI-I,
and to use it with VGA, you'd need adapters on either end. (A previous version
of the box, was fitted with VGA connectors.) There should be other
companies making these, with various programming options.

That's a good idea. I guess I could script it or something a la
RunOnce. What command do you give it? I've never used NirCmd but I do
use the other tools very regularly.

One good hack I found after some digging was to edit the .inf driver
for the monitor and edit out the modes you don't want (i.e., 70Hz, 72,
Hz, 75Hz, etc.). What I am experiencing is the fuzziness that most
LCDs do on non-native resolution with refresh rate above 60Hz. It
doesn't look bad per se but it just does have the crispness and
sharpness of native res or running non-native @ 60Hz. I've never seen
an LCD look good at anything above 60Hz at my shop. I'll keep the Nir
tool in mind. That site has the best tools for sure. Cheers!

I've not used NirCmd, but it is one I recognized from a Google search.
The URL I included has various commands it supports, one that looks
promising is "nircmd.exe setdisplay 800 600 24" (or in your case,
"nircmd.exe setdisplay 1024 768 24") and from
http://www.nirsoft.net/utils/nircmd2.html#using it appears you can add
"60" to force the refresh rate, and you'd probably want to use "-
updatereg -allusers" to preserve the setting for everyone.

Per Wolf K:

since W7 automatically selects the native resolution and
refresh rate of the monitor, why would you want to change them?

I'm running some PCs headless and I TeamViewer in from a PC that
has multiple monitors - one of which is 1920x1200.

In that case, the headless PC's native rez becomes irrelevant to
me.
