Sony AV receivers: STR-DN840 / DN1040

I purchased the STR-DN1040 to replace my old Sony STR-DE1075. To be fair all reviews agree that the STR-DN840 is a better value at $375 vs the STR-DN1040 at $525 and I tend to agree. What pushed me to the DN1040 was the front HDMI input (very convenient for tablets and phones), and the on-screen GUI. There some other features that I'm still not using but it makes this device more future-proof.

Any STR-DN1040 owners care to share some tips and tricks?
