I finally received the component RCA->HD15 cable for my NEC LT154. When I hooked up my Playstation2 to it for DVDs, I was horrified. I knew that some people used external scalers, but can the internal scaler really be this bad?
I'm seeing very noticeable jaggy pixels, this periodic vertical band pattern (slight coloration changes) with bands ~40 pixels wide, and moire patterns when people wear striped shirts. This is barely watchable, and only if I throw it way out of focus. When I grabbed my laptop and played the same DVD at the native 1024x768, the picture looked perfect.
I thought I had read that NEC's scalers were actually pretty good (and it does scale my computer signals decently). If the scaler really is normally this poor, then what are my options? My budget is already stretched from the new projector, new surround speakers, and an upcoming move... I'd just settle for using my laptop, but then I can't get the digital audio out. What's my cheapest option for getting watchable quality here? Should I return the component cable and not play ps2 games using the projector (that would be unfortunate...)?
