Some of the games I got won't display on my TV and but I can hear it, on my TV it says change the PC settings but I can't because all I get is a black screen and have to hold down the power button to shut it down. I try to go task manager and again can't see nor pressing the windows button lets me see what's going on. For example Shadow of Mordor and Outlast won't display but games like Skyrim will and Oblivion will. Is it a case of me getting a new TV or I really do need to get a monitor to play them? Thanks for the help!
