But, if you are using 480i resolution through your HDMI cable, you’ll see what’s on the right. The HDMI cable preserves all the great color and sharpness of today’s TV and just reduces the resolution.

Majority of non-240p retro games run in 480i so it's the safest bet, especially for PS2. Getting a 480p tv JUST for games will limit you to Xbox+360, Wii, PS3 and a few gamecube/ps2 games to take full advantage of it.

But you can still have 480p at crisp detail, which you would not see on most video streaming websites. With how websites like youtube work, 480p is a fallback quality, used only when the site thinks your internet connection can't support streaming higher quality.

If you are wondering what’s the difference between 480i & 480p, you are reading the right piece. There has been a lot of confusion over component video which is understandable, and whether progressive scan 480p output from a DVD player is better than 480i, interlaced output.
