I've got a 2007-era intel Mac Mini hooked up to my brand spankin' new Pioneer VSX-1120 AVR with a DVI to HDMI adapter + cable. The AVR is then connected to a Sharp 37" LCD (1080p), again, via HDMI. I also have an AppleTV 2 and a Samsung Blu-Ray player connected.
Most of the time the set up works great, but after a while--after switching between the other HDMI inputs, or bringing up the onscreen menu--the Mac Mini display ends up getting "cropped" and sometimes is off-center on the screen.
Once it's in this state, nothing I do (switching resolutions, re-plugging the cable, etc) seems to bring the screen back to its normal 'full' state besides rebooting the Mac.
Once I reboot it's fine, until the next time it decides to not be fine
-- I've been using the mini plugged directly into the TV for years and it "just works" at either 1080p or 720p.
-- I've tried a couple different HDMI cables, but that doesn't make a difference
-- all my other HDMI devices are working fine
-- I've tried enabling and disabling the various HDMI upscaling modes on the VSX-1120, also doesn't seem to make a difference
Any suggestions? Obviously, I could just plug the Mac directly into the TV but, one of the reasons I got the Pioneer was to simplify switching between inputs by consolidating all my connections (its replacing an Onkyo with no HDMI inputs). I'm trying to decide if I should keep this receiver or return it and find something comparable that doesn't exhibit this issue
