So I just got a Toshiba 39L1350U 39-Inch 1080p 120Hz LED HDTV, and it says that it can reach 120 hz with "clearscan".

So I plugged it in with an HDMI cable...which apparently can reach 10 hz on that TV, and in the control panel for NVIDIA it still won't go higher than 60 hz..not on 1080p, not on 1080i, nothing. Then I heard that it only works on cinema mode, but that option is greyed out and un selectable. There is no way for me to get higher than 60 fps. I tried on all picture options..like game mode and standard an PC but still nothing.

I heard that clearscan does not require download..what the hell is going on? Anybody wanna help? I dint know where else to post this than here.

That is because your TV cannot accept higher than 60hz of input at 1080p. HDMI, until version 2.0 is used, cannot accept more than 60hz of info at 1080p, and current GPU's aren't compatible with HDMI 2.0 anyway. HDTV's version of 120hz, just takes a 60hz signal, and does some on the monitor processing to create extra frames. This causes latency which is problematic with PC's, and is not usually available if a PC is hooked up to it (it wouldn't allow 120hz input anyways. If it did work, it would still only allow 60hz on the PC side).

Either return the TV and get a monitor that is 120hz or higher, or just accept that 60hz is all you can get with a PC hooked up.

All I want to do is play AC4 without the screen tearing lol. Damn..why is there still screen tearing? It hits 60 fps on a 60 hz TV shouldn't there be no problem? The engine can't even get higher than 63 fps anyway.

Playing on a 120hz monitor does not remove tearing, though it may make it less noticeable. If you don't want tearing, you use v-sync or g-sync. There are no other ways to remove tearing and no, triple buffering does not remove tearing, and tearing does occur when your FPS are lower than your refresh rate and yes, you still get tearing if you have 60 FPS on a 60hz monitor.

Your TV is 60hz as far as your PC is concerned.
