Computer screen on HD TV quirk

Today I helped a client set up his laptop to send a wireless signal to his brand new Panasonic flat screen TV using a Warpia Stream HD. I’ve set these up before, and I love them.

This time, though, no matter how we played with the resolution, the outer edge of the screen was being cut off, which makes it very difficult to, say, close a window, or use the start menu.

After some playing with the TV settings, it turns out that the TV’s default setting for HDMI input is to trim the outer 5% of the screen off, to try to reduce any potential digital noise around the edges. Maybe that’s fine for a TV signal, but for the computer, that clearly doesn’t work very well. The hardest part was finding the setting. It was in Picture -> Advanced -> HD Settings, and the HD mode was set to HD mode 1. I had to change it to HD mode 2. The only way to know about the whole 5% thing was to read the description of each HD mode.

Now I know where to look if the outer edge is being trimmed off.
