Hello,
I have some problems detecting the signal with these players : Sony UBP-X800, Oppo UDP-203 EU (in "Auto" mode, the "Direct" is working fine) and Swisscom TV 2.0 UHD Box.
When connecting the players directly to the beamer with the same Monster Premium 27 Gbps cable (no AV Receiver in between) , I get no signal or the signal is instable .
My 3 others sources or players are working perfectly : Apple 4K 5th Generation, Zappiti 4K Mini-player and Pop-Corn Hour A-500 Pro.
Does anyone has the same issues ? 
Is there any special Parameter to set ?
Is there any new Firmware correcting these issues ? C10 (I've read other posts...)
Thanks for your support.
David

    At distances of 4ft, all cables should work even with the new Ultra HD Blu-ray discs. But check out the following link about Monster Premium's '27 gbps' claim:
    http://www.echtek.net/truth-monster-hdmi-cables/

    Here are basic facts about 
    the V7850. It uses the 0.66inch Texas instruments XPR chip that has 4.1 million mirrors that results, after a diagonal pixel shift, in 8.3 million claimed pixels on the screen and a resolution of 3840 x 2160. This faux approach is similar to the JVC and Epson methods of 4K and the V7850 is not a native 4K projector. However thanks to the single chip used in the V7850 compared to the three-chip approach of the competition, the image is sharper on the Acer than the JVC and Epson, where panel alignment issues make things look slightly softer. You will find it hard to pick out the resolution differences between this projector and a JVC compared to a native Sony 4K unit from a normal viewing distance. 

    Now, the V7850 will accept a 4K 60p HDR signal via the HDMI 2 slot and is capable of displaying this in Rec.709 color on screen. It does not support HLG or Dolby Vision HDR. There are modes within the menu which can boost the color response over that of Rec.709 but I would recommend to leave these switched off as they quickly make things look overcooked if not expertly handled.
