I have an older laptop and would like to display a video file on a TV. I have a RCA video out of the laptop and there is a software setting to switch the video output from the monitor to the video out port. When I do this, the video is not the same resolution as the TV so I have to reduce the size to see the whole picture on the TV. Is there any way to change the resolution of the output so that full screen on the monitor is full screen on the TV?
