Resolution locked to 1024 x 768 on monitor and projector
can anyone explain a problem we are having. We have a setup where by the projector clones the image on the computer. We have a VGA to wall panel VGA whcih then runs to a projector on the ceiling and then a VGA out on the wall panel which is plugged into the monitor.
The widescreen monitor we use, its native res was 1920 x 1080. If we just plug the monitor straight into the wall panel, we can only set the resolution on the computer to 1024 x 768. To get it to display 1920 x 1080 we had to plug the monitor directly into the computer and set it. Once set, we then plugged everything back in using the wall panel and the projector and monitor were displaying 1920 x 1080 res, albeit quite small on the board which I think would need the projector moving back in order to fill the board. But then once we reboot the computer something forces the resolution on the computer back to 1024 x 768. So by going through the wall panel the res is being forced to 1024 x 768 and not really sure what it is doing this.
Anyone know what causes this?
