Switched Z 10 pro to Amazon's FireTV OMNI(TCL based)-black screen, no signal.

Hi. I was using Z 10 Pro a year with two Samsung TV's and never had problem.
So upgraded to FireTV OMNI(TCL based) 65" and NO SIGNAL FAUND after LOGO shoving up and that's it ! Got brand new 8k cables trough 4k Yamaha Receiver(Home Theater). Tested straight to TV all HDMI inputs but same problem. Was using 3840x2160 60 hz DV on all settings(no HDCP). Looks like TV doesn't like Zidoo's setup but couldn't figured out which.
Any help? Thanks.

 

DV is either 12-bit 4:2:2 or 8-bit RGB depending whether you choose Player Led or TV Led, but in either case, at 4K60, this is full chat for HDMI (594MHz, 17.8Gbps) so this is likely a bandwidth problem.

Press the resolution button on the remote a couple of times (leaving time between presses for HDMI sync) to get an image back and go from there.

Finally fixed it by following your recommended settings, thanks for it. (http://forum.zidoo.tv/index.php?thr...r-useful-stuff-for-rtd-1619bpd-players.95967/)
The only problem is now i got 2-3 sec hold ups before start of movies and file play feels little choppy i guess.
Any idea?
Thanks.
