My laptop connects fine to one of my TV's via HDMI, but won't connect to the other one. If I plug the HDMI in on boot up, the display shows only on the TV for a few seconds, but then once I actually get into Windows, it won't let me display on the TV. I've tried updating drivers, tried changing the resolution settings and everything but no luck. Maybe it's the TV that's not working but other HDMI devices, such as my PS3, work fine on it.
