Yes. Just make sure it's like I said. Read the OP. Would solve all your problems.

Thanks for that.
After playing with the settings for some time changing everything I can find to PC 0-255 seems to make things look a lot nicer.
Not sure what is going on every\thing I've read says to do the opposite but the 16-235 makes everything very grey to almost maxing out the contrast on the tv to aleviate it. Cheap tv from 2012 with no settings for 'deep colour' or anything like that (although there is some sort of dynamic contrast going on with the internal leds which there is no control over) with a gtx 550 ti going through hdmi

You should not be touching your TV settings to make this work. Research what is the most accurate mode / settings for your TV and go from there.
