First off: WOW @ the clarity. I don't know how I've been living in 480i. Even the menu looks sharp and crisp. Can't wait to pop in a game.
But yeah, my Nintendo cables came in just now, and after hooking them up, I've noticed that the massive overscan I used to experience is gone now. I didn't even know that was a symptom of cables, I thought it was my TV (I get some overscan when using my PC via HDMI). This is fantastic! Unexpected bonus value. The only downside is that now I see the notorious black borders in the Opera browser. But I'll take it.
