Yes color temp. All I as saying is that doing an ISF can 1.) greatly correct the picture overall, and 2) reduce burn in, so it's a worthwhile thing to do.

As far as the color bars, some displays have color bleed, and that maked it more difficult to get the color dead on, but it will usually get you closer to perfect than W/O using Avia.

As far as the screen door effect, I can only think it's processing, as was already mentioned.
