The Arris Set top box has a problem working through the AV receiver. Verizon tech support don’t know how to assist in this case.
The STB identifies 720p as the resolution and then if switched off cannot output any image through the receiver. When connected directly to the TV it still does not show a signal. It’s at this point not getting the handshake or the resolution has gone wrong.
If if I keep the STB on then the system works powering the receiver and Tv off and back on but it then goes to 480p.
is there a way to access a service menu? Is there a way to fix the receiver to stop the repeated resolution changes and speed up the handshake.
Solved! Go to Solution.
Clem, many thanks for your reply. As a point for folks who have handshake issues use a hdcp converter.
In in my case the resolution was to use a blackbird converter to make this a hdcp 1.4 output to the TV. Now have a solid connection to all devices!
Also from the Sony manual, look at this:
Press AMP MENU, then select
“<HDMI>” – “SIGNAL FMT.”. Select
the input you want, then press .
STANDARD: Selects this when you do not
use high bandwidth video format.
ENHANCED: Selects this when you use high
bandwidth video formats such as 4K/60p
4:4:4, 4:2:2 and 4K/60p 4:2:0 10 bit.

When “ENHANCED” is selected, we recommend
you to use a Premium High Speed HDMI Cable with

with “ENHANCED” setting. In this case, select
If your TV have similar menu for high bandwidth

Thanks for the reply. I have cec on and off. Enhanced and standard. Thru and no thru signal.
The receiver is identified correctly but when the tv is switched off the handshake does not happen. I am not sure why the handshake can occur initially and then fails. If I can keep the STB in a non handshake setting that would work.
No issues with the blu Ray and Xbox. Actually the vms1100 was also ok too but the 4100 is not.
For or some reason the 4100 won’t recognize the scaler in the TV at 1080i and insists to hold it at 720p. I will try it again.

Have you tried different HDMI cables? Try swapping the VMS cable with one of your other HDMI cables. It's odd that the VMS won't see your TV as more than 720p capable. What TV is it? No chance the receiver is down sampling is there? Did you try manually entering your receiver into the VMS setup under voice control?
Yes on the swapped cables. Used the cables that came with vms4100. Also tried the manual install and can control the tv STB and receiver to control volume and power on and off.
the tv is an older tv, plasma th-42phd6uy. The 1100 worked though out the box but the 4100 is not. The 4100 won’t let me control the unit to 1080i. I think it reads the scaler as 768 pixels so it controls in to 720p which is fine.
Still the handshake fails fails despite the setup. Can only think of trying a hdmi switcher that keeps the signal on. Will update on that.
