Welp, my M65-D0 is going back to Costco.
1. HDMI Handshake Issues
Detailed below. Have to route Comcast STB through XboxOne in order to get consistent power on HDMI handshake. Comcast STB direct to any HDMI port just won't handshake. Tried three different STB boxes, all the same issue.
2. Picture freezing.
Twice on cable, once on movie playing over network, once on movie playing from Xbox disc drive. Picture freezes, audio continues. Power cycling the TV resolves, while source continues to play fine.
I really like this TV, but more issues in 10 days than the last 10 years of Panasonic & Samsung is all the info I need.
Now I'm torn on exchange vs abort. My first Vizio experience, not sure if I got a bad unit, or if it's just bad product.

Just setup a M65-D0, with the Costco discount.
Having issues with HDMI handshake to the Comcast box.
Comcast STB on port 4.
Xbox One on port 5 (all good here, no issues)
When turning on STB & TV, the handshake will not succeed probably 50% of the time. Black screen. Top of screen status recognizes the input as 720p or 1080i. Turning off the STB changes to "No Signal".
Power off/on of the TV and/or STB, or input switching will eventually resolve, then all is fine until powered off.
Have tried STB on other ports, same issue. Have tried other HDMI cables. Have tried 720p option on STB. CEC is off.
Next test is routing Comcast through the Xbox, but not my favorite option.
Any ideas or experience concerning this issue? This is my first run-in with handshake problems.
Thanks in advance.
