What a fecking day,
Decide to bite the bullet and buy a new TV,which I might add he is paying for,after forking out for his Xbox One already,
So trawl through page after page of TV's looking for something that will have the necessary connections to accommodate all his original gear plus the Xbox One,and eventually find this,which is at the top of his non-existent budget,
Buy Samsung UE22ES5000 22 Inch Full HD 1080p Freeview LED TV. at Argos.ie
So off we go to collect,about 10 miles away to the nearest Argos store that had it in stock,and another 10 miles back home,
Unpack it only to find that the afore mentioned DVI connection is actually a HDMI/DVI socket,and no adapter in the box,not to mention it would mean having to plug/unplug every time he switched between PC and Xbox,
Silver lining in the end though as it did have a VGA connection which gives a resolution of 1920 x 1080,didn't realise VGA went that high,so that the PC connection sorted,eventually,
Xbox One into the HDMI and we are rocking,smiles all round
Thanks for all the help and suggestions guys its appreciated
