[SOLVED] Dodgy colour when connected to TV via HDMI cable

I have an HP Pavilion dv7-6050ea, and I've connected it to my Samsung UE32D6100 HD TV. Unfortunately, the colour looks awful, and I've tried my best to adjust it. I have tried playing with th settings of the TV, but I can't get it to where display well. I tried using the 'calibrate color' option in the display settings of Windows settings, and I found a configuration that works, though it's not perfect. The problem is, every time the screen saver comes on, the settings revert to default.

Any ideas?
