I recently bought the 360 vga adapter after reading from numerous sources that it was native vga. This is a straight out lie, like last gen's output adapters, 360/ps3 use component signals or simply converts the analog vga outlet. It is analog not vga, which proves my theory right. The Dreamcast vga invented HD tvs. Its signal is not analog it is completly native res, with what seems to be HD-TV perfect resolutions. The 360's horrid component signal(in 480p) is marketed as native except it is not. The port has no vga built signal so no monitor cable will work, except component for which it was built (which is why it looks so bright and blocky). It is just an analog signal, any idiot can see this at 640X480, 480p or watever res with AA and light colors screaming analog. I am sure ps3 is the same way due to its heavy manufacturing costs. Dreamcast is the only true vga signal at 480p. Once more, I recommend Dreamcast, Still thinking.9-9-99 through 9-9-09. Happy missed aniversary as well.
Reccomendations: Upscaling is now a fact. People didnt notice this on PCs (after dvi which imo is much better than direct vga because it doesnt upscale) and now is used on 360 (not to be confused with pixel meshing or bluring, eg scaling textures within textures...no...consoles cant do that unless upscaled or developed that way). Upscaling helps AA problems but thats about it, it is used widely on Dreamcast or PC to HDtv, which is okay if your PC matches the output. Dreamcast, and custom PCs on the other hand will not need it. Dreamcast uses 640 so if the res is upscaled it will appear bland like a component signal. The best solution here is to get an vga-to-HDMI 50 dollar converter or a DVI one if they have it (DVI is tricky, it needs res adjustments to a particular brand of tv eg 480p to the native res signal so PC is the best bet or beware adjustments in res with your device). pc is best when used with a component converter, albeit 360 and ps3 are fit for custom tvs (eg ps3 on sony's hdtv gives 1080p a fuzzy effect, whilst 360 gives it a better effect than 720p somehow? due to darkening the paneling of a large screen, some manufactureres may indeed use different plasma lighting methods, ie dark is better for large environments, and @ the same time shuns effects see tv comparisons and tests). Gamecube and xbox has component-to-hd converters as well. On consoles like Ps2, upscaling is not necessary, because playstation 2 lacks AA (eg vertex shaders, triangles etc) unless with developed but rare 1080p games (here is the trick, they upscale on ps3 to make it 'look' like no AA problems appear on a ps2 game. Stuff we already know like 640p results in 480p res (not really noticable on diamond 'ctr like' bulb screen hdmi tvs). Component upscaling will still show AA, the best bet is S-video for picture quality. Also color bleeding is a common problem on ps2 except for maybe plasma tvs. Ps3, Xbox 360 and PC def lead in HD quality followed by Dreamcast, Xbox and Gamecube and finally ps2 and n64. Most if not all converters except for maybe vga dreamcast will scale just a little or alot depending on the input eg svideo, component than vga, to mach the pixel on your HD. Note: certain games, as mentioned will not work in vga for dc, or have the right colors or do they use svideo-to-component (converters usually can upscale to 720 only or they may need to downscale unlike component-to-hdmi converters sadly eg rgb color conversions vs a cable signal) and this problem still occurs on xbox 360 games (eg too much green, lazy dev lack using AA). There you have it...Sixth and 7th gen reccomendations.
Tip: Here is a pro tip from hardcore gamers on setups. HD-Tv is always perfered at a 720p hi res for xbox 360. Ps3 may be the same deal except most of its games only work at 720p anyways. If a game like Batman AA for example is at 1080p, or some monitor res, its textures diminish and are flattened. No linen will be seen, so it gives the illusion that the game is not made for HD-tv, but any format at any res when that is not truly the case. 480 is an analog signal so dont even touch that! Quality over quantity is waht i always say, the 720 res textures are flattened when scaled to 1080p. Unless the game is built or programmed for it, stay away! Xbox 360 is truly customizable, except sometimes best left untouched. Any gamer will tell you this.
