Your change to TX1 definitely looks like an improvement.
In order to make a determination on the best course of action regarding the keepout at the connector end and whether to recommend some type of taper I still have a burning question:
What does PADS currently give as the impedance of the HDMI differential lines?
each line is 90 ohms.
Does it give an impedance for a particular trace?
yes. 90 ohms. or... 89.
(That would likely be the single-ended impedance.) Does it offer a differential impedance value for a pair of traces?
no. from what i gather you're expected to read up on diff-pair rules.
