Hello, I've found an old TV ("HD-ready") than can only get component input (no HDMI). Anyway through using old parts I've managed to make an underpowered HTPC to drive that TV. Only problem is that the resolution is locked at 720p. Though nVidia control panel I've managed to enable 1080i but the image quality gets much worse and most of the image is outside the TV's frame. Now, I know that that the TV supports 1080i (it says so on the manual). The HDMI to component adapter supports 1080i too, why then the result is as atrocious? I'm going to use the the TV for light desktop computing and (mostly) videos/movies. Nothing too demanding (no gaming). 720p makes it useless for desktop use though, everything's too big. Any idea why 1080i misbehaves? I've read of this issue quite a lot on the net but most didn't know why it is so. Others were able to output 1080i no problem. My graphics card is a GTX 750 ti, it's the only relatively good part of that HTPC so I'd imagine it should not be culprit. Any ideas? Thanks.
