My main TV for console games (PS4, Wii U, PS3), movies and TV shows is a LG47LM615S (47'', 1080p, 3D, LED):
If I want a bigger screen for a game or movie, I switch to my Sony Pearl projector (VPL-VW50, 1080p, 2D, LCOS/SXRD)...the AV receiver has 2 HDMI-outs (and many HDMI-ins), so switching between both setups is easy:
My second TV is a LG42LN5406 (42'', 1080p, 2D, LED). At the moment, my GameCube and Xbox360 are connected... the PS3 will eventually move there, when I need the space for a Xbox One in the other room:
My PC is connected to a Dell 2407WFP (24'', 1200p, 2D, S-PVA) and an Acer GN245HQBMID (24'', 1080p, 3D, TN). The Dell is my main monitor for desktop stuff and slower games (point&click adventures, strategy games, RPGs...), the Acer for racing games and shooters (120 Hz) or stereoscopic games (2 x 60 Hz). Or I use both together, when I need more screen space... switching between the 3 setups via Windows-Hotkey is easy:
