Okay so we're holding an approved event at out school and are planning to display the final match onto a projector. However, the projector only has a VGA input. My GPU has HDMI/display port and DVI. We're looking to use a dvi to vga adapter for this.

What is the max resolution that will be displayed on the projector, on the monitor (HD monitor supports 1920x1080) and what resolution can be recorded in?

We'll be using a dvi cable to connect my gpu to a small adapter thing which connects to the projector input box. So since it's a dvi cable it can handle the resolution? But since it has to be converted to vga at the end for the projecter, what happens?

Thanks,

Since the projector only has a VGA input I wouldn't be concerned so much what resolution VGA can do but what resolution or size the projector actually outputs at. Check the product number and look at all the details, I would read the manual as well.

The VGA cable should be able to support 1080p fine.

The projector seems pretty new, but I will check the model number tomorrow. It's one of those standard classroom -drag down a clean material to display- sort of projectors.

Since you said VGA will be fine for 1080p, how's the suffering of quality?

Ok I will. But just asking, if I have my resolution to display out from the gpu to monitor @ 1920x1080. and the projector only displays up to 680x480, what will happen? Rescaling? or no display at all.

*Edit: And this is through a vga cable afterall, not dvi, sos. it's dvi adapter from my gpu to vga cable and that vga cable to projector input hub.

When you hook up the projector it will be configurable as a second screen. Set the options for it to extend the displays and set the resolution on the projector screen to whatever it will support.

As far as recording anything, you can record at whatever resolution the input is at. The output to the projector does not have anything to do with that part.

ok so from my game I set the resolution to 1920x1080. The monitor connected via 1st vga splitter would be displayed @ 1920x1080 aswell? For the 2nd vga splitter end the projector would convert that 1920x1080 to the highest display output resolution it supports?

You're using SPLITTERS or adapters on different outputs? Those things behave totally different. A video splitter just splits the signal into multiple paths at the same resolution. And at that high resolution, you better get a high end splitter and video cables or you'll have ghosting in the image.

The project won't convert anything, it will either display it at the same resolution if it can, if not, you'll get no signal.

If you are planning to run the same image to several different displays, you need to run all the displays at the lowest common resolution.
