TVs are really stressful. Most everyone has been up there giving a powerpoint presentation. And the screen won't come on. Seriously, why haven't we fixed this problem yet? This is the classical user experience for me. I want my screen to be smart enough to automatically switch to the computer that I just plugged in. Same with TVs when I plug in an xbox or a presentation.

Here's two ways I'd do this.

1. Have an autoscan feature that looks for input signals and only skips to plugs that actually have a signal coming out.

2. When you are selecting your "mode" show each tv screen as a small picture and allow the person to select which screen he wants visually. They don't even have to be updated often in real time.
