Hi all,

I would like to find a way to only project on a part of my 4:3 format of my projection. I would like to set the aspect ratio/resolution to something custom.

I'm planning to project on a area that has a 20:9 ratio. I could of course do it by creating a powerpoint at make all of the "extra" projection area black. But is there a more fancy way to do it? It would be great if I could set my whole desktop to this aspect ratio in some way.

Is it understandable what I want to do?

MAYBE!

Your projector only handles certain resolution formats. So, no matter what, you have to feed that resolution to your projector.

If you want to adjust your aspect ratio, and the projector does not have a custom aspect ratio setting (most don't do this), then you would need an external video scaler which includes this functionality.

A product like this SHOULD do it:

But, there may be lesser expensive solutions, and if you are using a PC, there may be a way to setup the video card, or to use an external program to adjust the aspect ratio for what you are using ahead of the output stage of the graphics card.

EDIT: I just checked on my laptop which uses an nVidia card. It is in the settings for the video card and only took me a few minutes to figure out. I went into the video card settings and it offered me the ability to 'resize my desktop'. I clicked on it and it gave me some arrows that I could drag and drop until the desktop was resized the way I wanted it. It was very straightforward and would do exactly what you are asking for. My desktop was not as tall anymore, and the applications only filled a part of my monitor.

It seems like my nVidia card/or my projector, don't suppot such a setting. Any idéa of what external program/software that might do the trick?

Are you sure about that? Realistically, this is a discussion you probably should have on some PC forums as I know very little about the different options for PCs in this regard.

What kind of video card is your PC using?
What kind of computer is it? Laptop? Desktop?
What operating system? OS-X, Windows 7, Windows 8?

Do you know how to get to the software which allows for fine tuning of your graphics card?

What is the name of the control panel which you can use to manipulate your graphics card?
