Help with HTPC > Dr HDMI 4k > Sony Z9D

[tzr916]

I tried the duplicate display method - ran a second hdmi cable from onboard intel hd 630 graphics through MDK directly to another input on the Sony tv, set windows display to duplicate mode both running 4k. Unfortunately the intel hd 630 doesn't do HDR, which prohibits HDR entirely, ruling this method out as a viable solution. And more importantly, it did not solve the issue when power AVR Off/On, Jriver MC Theater View program resizes / improper blanking when playing video (still shows a box in the top left corner of the screen for a few seconds before video starts).

So I've resorted to a workaround - program extra commands in my harmony remote to change Jriver MC to Standard View and back to Theater View whenever powering the AVR+Tv On. Not as elegant as I would like, but it works without any extra devices.
