Dear Talented Gurus,

Please help me. I need to read some monitor information, for example, gamma
ramp, color values, and whatever information the monitor have from EDID or
from the display driver?

Anybody knows how? and I hope to find source code which can show how to do
these on Windows XP...

Also, I am doing some interesting stuff. Do
you know how can I get the monitor's physical viewable size(in inches), and
how can I get phosphor type of the monitor(e.g. square LCD, or dot-shaped
CRT, and the layout of the RGBs)? By the way, I am curious about if I can
read projector's viewable size if it is connected to a projector?

Thanks a lot,

-Lucy
 
Hi,

All this information will be provided in the display properties window.

If you have installed one of those special AGP Cards another additional window will appear. to access this do the following

right click on the desktop
choose properties
then go to the last tab which is usually the place where you set the resolution
click on the advanced button.
a dialog box will appear and you will see a tab with that name <depending on your brand>.
Open that tab and you will get all information that you need. Note that the information available will depend on the capabilities of the card and will vary from vendor to vendor.

and this more importantly:
http://msdn.microsoft.com/library/d..._dc0bda84-97c5-49ba-9084-04149f9be157.xml.asp

Doing a little searching on MSDN will net you a lot of answers. The
ability to gather some of this information is done through the drivers
that are loaded. There may be limitations as to what information can be
gathered because of this. Unfortunately, most of this will require you
spend a lot of time learning about driver functions, may even have to
develop your own drivers and software in order to do what you want. As
for the projector, it should have similar information as a monitor so it
will provide information about itself as to its max resolution and such.

Hi Nathan,

There aare really very good. Thank you very much. But a second look shows
that they need DDK. Am I right? And DDK is not obtainable by free, right?

Any more ideas?

Thank you very muhc,

scroll to the bottom, download & install the EDID.EXE utility.

start it, do a "Get EDID" then a "Translate EDID".

Step through the byte values one at a time, the values
and what they mean will show to the right.
