Are you able to use extended mode or clone/mirror mode to confirm that your tv works?
When you create a display group with your monitors after you pick whether you want a 2x1 or 1x2 setup it should show two boxes in that window next to eachother with a dashed white line between the boxes with a # 1 in it. If you do have the display group set up check to make sure it is double the native resolution of your smallest monitor and check the refresh rate, it might be possible that your tv is only 30hz while your monitor is at 60hz and CCC is still leaving it at 60.
My TV is full HD whch is at least 60hz, its a samsung series 5, but I will try checking out whether it is 2X1 setup. What I want is just an extention of what IM playing rather than an extended desktop, meaning its like having two monitors, thanks though.
