360的倍頻是由獨立的晶片來處理的
只是由軟體來設定輸出值而已
所以是硬體處理,而非"軟體訊號增強"
簡單來說，就是以下幾個重點:
1.沒有原生1080p的遊戲可以輸出。
2.XBOX360可以透過晶片來做硬體倍頻。
就這樣兩個重點而已...有必要大家這樣吵嗎?

底下是bugie對於halo3的聲明. halo 3在同時跑了兩個640p frame buffer.
單張抓圖不能做準, 按照正常的算法那應該是1280p....
底下是bugie的官方聲明 可於官方網站找到
One item making the interwebs rounds this week was the scandalous revelation that Halo 3 runs at "640p" which isn't even technically a resolution. However, the interweb detectives did notice that Halo 3's vertical resolution, when captured from a frame buffer, is indeed 640 pixels. So what gives? Did we short change you 80 pixels? Naturally it's more complicated than that. 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. This ability to display a full range of HDR, combined with our advanced lighting, material and postprocessing engine, gives our scenes, large and small, a compelling, convincing and ultimately "real" feeling, and at a steady and smooth frame rate, which in the end was far more important to us than the ability to display a few extra pixels. Making this decision simpler still is the fact that the 360 scales the "almost-720p" image effortlessly all the way up to 1080p if you so desire. In fact, if you do a comparison shot between the native 1152x640 image and the scaled 1280x720, it's practically impossible to discern the difference. We would ignore it entirely were it not for the internet's propensity for drama where none exists. In fact the reason we haven't mentioned this before in weekly updates, is the simple fact that it would have distracted conversation away from more important aspects of the game, and given tinfoil hats some new gristle to chew on as they catalogued their toenail clippings.

所以...用色差就夠...(恕刪)
1. 1080p的畫面，的確用色差就夠了！ 但現在大部分電視的色差只支援D4(1080i/720p), 而HDMI反而有支援1080p, 所以HDMI 1080p算是比較方便的方案。
2. Xbox360 的倍頻計算算是不錯了！ 雖然有點模糊，但也算是一種特色！ 而且Xbox 360的焦點外模糊效果的確不錯！ 玩起遊戲有種快感！ 總比PS3的一大堆鋸齒好多了.....(斜線不像斜線，弧線不像弧線)
3. Xbox 360跟 PS3雖然同樣是512MB的記憶體，但OS所佔容量的差異，卻影響到顯示的效果，以及遊戲系統所能使用的記憶體空間。 像刺客教條，PS3版原本會固定在某一場景當機，而Xbox360版的不會，而該場景是需要大量記憶體空間。(本人推測最新的Xbox 360 OS容量約9MB以下，而PS3一直是一百多MB.)
