Found out the problem, I did try and change the settings and it did nothing, but I first connected the XBOX to my housemates TV and it worked perfectly first time, so I used his HDMI cable on my monitor and it worked fine! Why is this though, if I can use the HDMI cable to connect up my laptop and PS3 to my monitor fine why does it have issues with the XBOX, I also assumed that all HDMI cables are pretty much the same...
Well the main thing is its working now i guess all HDMI cables are not the same
