I just bought a new monitor for my computer. A samsung 21.5" Wide Led Monitor with Full HD 1080p. I believe its called a SyncMaster Ex2220 and its a series 20. It also says its Breakthrough LED picture quality. I usually play my Xbox 360 games on my computer with my VGAHD cable and now that I have a monitor that can display this 1080p resolution I was wondering if there was any way I can play my games in HD. Do I have to buy any extra cables for the Xbox so it can display that resolution? Any help would be greatly appreciated.
