Hi, I'm new here and new to Sony tv's I have just bought a KD-49XG7073 4K TV

And I don't use analogue or digital TV channels I just use the hdmi inputs,the problem is when I use the hdmi inputs I can not get any screen adjustment settings to come up to change brightness, contrast, colour or screen size ie width can anyone tell here is a picture of my remote but I've tried the obvious buttons, home, options and they don't do anything when using hdmi sources. 

Can anyone help please
