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

Are you changing the levels of your GPU when outputting at 16-235? The GPU must be set to 0-255 to allow for passthrough.

The three different scenarios are explained in the set-up guide. You should get proper levels when trying any of them. Unless your TV is fixed at 16-235. In that case, the third option (setting the TV to 0-255) will not work.

So, try option one and two, adjusting all of madVR, Kodi and your GPU. Option one would be my choice. But option two can lead to better picture quality.
