Does anyone have an example of how to get the PHYSICAL monitor size in C#?
In C++ I used to use GetDeviceCaps( dc, HORZSIZE ) which returns the monitor
size in mm, then I
converted it to inches.
When I do this as unmanaged code in C#, I am getting back a value that show
my 19" monitor
has a width of only 12.9", whereas my trusty ruler shows it to be about
15.5".
Is this a driver problem, and if so, what am I to do?
Thanks in advance,
Chris Hough

If it's a driver problem then your C++ program should have the same output.
as your C# program. Does it?

My C++ program does produce the same output.
I should have said in my original post that the monitor is a 21" (not 19")
Hitachi CM801, video card is NVIDIA RIVA TNT 2 Model 64, resolution set to
800x600.

I would be very doubtful you could rely on a function that returns a
monitor size, given that you don't know where windows is getting the
monitor size from. Windows has never asked me how big my monitor is...
There are monitor drivers, but how do you know you have the right one
installed (as you are finding out)?

Exactly. The computer doesn't *know* the physical size of the monitor,
unless the driver *happens* to include that information. The computer
generates pixels, not inches, and without making any change in the computer,
you can plug in a different monitor and get the same picture, a different
size. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I just purchased a Samsung 930B flat-panel monitor. Its *recommended*
resolution is 1280x1024.
I was previously running at 1024x768, but I also work with graphics. Any
images that were square or circle looked about 10% taller than they should
be. Naturally, correcting the screen resolution to the monitor's native of
1280x1024 fixed this and displayed more accurate proportions.
Because this change made all screen elements microscopic,...

Hello to all, and happy new year!
I have this application that someone wrote that I'm

the bottom of almost every form. I haven't figured
out yet if there's a pattern to it. I compared two
forms -- one that looks okay and one that gets cropped,
and aside from the size and the accept button and
the cancel button, their properties are...

I am trying to monitor the process of a file being copied, but I

something like this before? I would rather do this instead of trying

I have a semi-urgent need to solve a problem in Java.
I have three small images that I need to hold to a constant size (e.g., 1 inch) regardless of both monitor size and resolution.
Basically it breaks down to this series of events.
1. Determine the users monitor size.
2. Determine the users screen resolution size.
3. Calculate the height and with to scale the image to for a constant size.
4. Display the image.
