Halo 3 Resolution Explained

Bungie has finally released the reason why the resolution of Halo 3 is not true HD like it was promised. After videophiles relentlessly claimed that the Halo 3 picture was being stretched instead of running in the full 720p, Bungie has now stated that they decided to use the awkward resolution of 1152x640 in order to preserve the "High Dynamic Range" or HDR. I haven't personally felt that Halo 3's visuals have been underwhelming by any means, but I understand the uproar over the matter. They promised HD and in reality there is not true HD. Here is exactly what Bungie said:

"In fact, you could argue we gave you 1280 pixels of vertical resolution, since Halo 3 uses not one, but two frame buffers – both of which render at 1152x640 pixels. The reason we chose this slightly unorthodox resolution and this very complex use of two buffers is simple enough to see – lighting. We wanted to preserve as much dynamic range as possible – so we use one for the high dynamic range and one for the low dynamic range values. Both are combined to create the finished on screen image."
