Yeah, but I was expecting that. What I wasn't expecting was the
softening of the image in the plasma. I saw both sets driven
in two ways, direct hdmi, and via a box that scaled down to
480i. The Plasma didn't show a huge difference between the two,
where as on the LED the difference was startling.

Trouble is, it's a bit too late when you've got it home.

Good advice. I've started doing that, and I'm finding a lot now about
Plasmas having a softening effect on the image.  Some people saying it
took them a while to get used to it. Someone suggested it was due to
the dithering that Plasmas have to do. I don't think there was anyone
saying they felt they'd made a mistake getting a Plasma. What bothers
me though is I'd like the option to play high-quality 1080i into a 1080
set on not lose resolution. Softening is in effect throwing away resolution.

I'll do exactly that. I'll grab the manual and return to the shop - see
if I can get sharpness out of the Plasma to equal the LED. In theory,
although it isn't ideal, a sharpening filter should be able to partially
undo any softening effect of the technology.

That's interesting. I'm hearing that a lot in the forums too. Just a
shame about the softening thing, and with the constant improvements
in LCD (particularly LED), it's less easy to rule it out.
