Depends on your display... try both and decide What You like... Some swear by this brand or that brand a lot are way over priced... (monster)If it came with component try these first...My .02 cents...
With an H10 receiver, if the TV will support this feature, the HDMI cable will allow the box to talk to the TV and automatically adjust the resolution as you tune from channel to channel.
If you like what you see with component connections leave it alone. Opinions vary but there is not much difference at all. ( if any) IMHO, don't waste your money on over priced cables.
