It's been a little while, but I wanted to post a small update.
I recently acquired an LG L246WP-BN monitor for my computer, and it so happens to have HDMI and Component input.
I "stole" a HDMI cable from downstairs and hooked up my monitor to the HD-DVD player... and let's just say 1080i looks great on it!
Upconversion of DVD's is greatly improved using the HDMI connection.... considering it'll go 1080i instead of my tv's 480i limit (due to component from the HD-A2).
Seth was there.... he liked it
