I just got a new laptop and I can't get an image to my TV from it and was wondering if anyone could have a solution for this.
Laptop is Lenovo y510p 2x GT755m and tv is LG.
I can see that that TV is recognized but still I get no signal. Have tried switching the hdmi slot and turning computer on and off but nothing seems to help.
I suspect that SLI is messing something up. I tried playing a game with TV still hooked in with the HDMI cable but the game had 3d visuals all of a sudden. Removed HDMI cable and everything went back to normal.
TV work perfectly fine with another laptop.
Anyone have any ideas?

Yesterday I got it to work by changing my refresh rate from 59 to 60. Got the image to the TV and went to sleep. This morning the refresh rate is back to 59 and now it changes it back to 59 every time and the TV wont get signal.
