In the office, I keep the Surface closed, connected to two 21 inch monitors, both landscape, one of which is a touchscreen to get around the aforementioned mouse issue that presents itself when I use the 42 inch television in my office to stream sports/major news stories. The TV, across the room, is connected to the same Surface via a Microsoft Wireless Display Adapter.
Monitor 1 is mostly Word Processing/Excel with a taskbar across the bottom because I am not a heathen. Monitor 2 is the touchscreen with no taskbar and is essentially only a web browser (a browser is really the only thing touch optimized in Windows 10). And the TV is only a web browser for MLB.TV and YouTube TV. I left the taskbar on that screen but it disappears as I watch most TV in full screen anyway.
