So I just got Half Life 2, Portal and Team Fortress 2 for my laptop. My laptop screen recently broke so I have to connect it to my TV via a HDMI cable. Whenever I click on any of the games absolutely nothing happens, the loading thing on the cursor shows up but that's it. The game does however show up on the Task Manager but not on my screen, does this have anything to do with me having to connect it to a TV? if so please help.
