One of the 2700's best features is also one of its most confusing. Input Selection and Configuration is actually a multi-step mapping process but has defaults that support most common uses.
Each main user input selection like "DTV", DVD", or "Cab/Sat" can be configured through the on-screen menu interface to use one, several, or none of the numbered rear panel I/O jacks (HDMI, Component, Optical, etc).
For example, the main input selection of "Cab/Sat", by default, is set to use the rear HDMI port "Inp 3" which, as the default, is so labelled on the chassis as "Cab/Sat". However, it could b use for any HDMI input need. It can also be set to NONE meaning "do not look for an HDMI input".
There are several confusing aspect to the mapping process:
- The rear chassis device labels (like "Cab/Sat") printed along side the numbered or lettered port (like "Inp 3" or "Inp A") are only suggestions and not mandatory. It is the numbered/lettered labels (like HDMI Inp 3) that are important and remain unique regardless of how the I/O ports are mapped.
- Each main selected input has separate mappings for each of the supported connection types such as HDMI, Component, Optical, etc. Thus, a single main input selection can be mapped to its default HDMI I/O port while also being mapped to a component I/O port default-labelled on the chassis as being for a different device.
- The mapping of main input selections is really to the numbered/lettered ports, not the labels on the rear chassis. For example, by default, the HDMI port for "Cab/Sat" maps to "HDMI Inp 3" which, only as a OEM suggestion, is labelled on the rear chassis as "Cab/Sat" but could, just as well, accept any other HDMI input.
- Also confusing (at first) is that the on-screen input configuration menu lists the selected rear ports using their unique port number (good) but also lists them with their currently assigned main input selection which cnages as you reconfigure.
For example, if you are configuring main input "Cab/Sat" and set its HDMI input to use "HDMI Inp 1" (labelled "DTV" on the rear chassis) then the configuration menu thereafter lists HDMI Inp 1 as "Cab/Sat". What really confused me, at first, was that I thought the port names shown in the available port list were fixed and matched the rear panel device labels. THEY ARE NOT! The device names in the port list for a given I/O type of a given main input selection are simply their current mapping and will change as soon as you reassign the port. So, only go by the actual port number/letter when figuring out what goes where. To whip a dead horse, if you select "HDMI Inp 1" for your main "Cab/Sat" input, then the HDMI port list for Cab/Sat will then list "HDMI Inp 1" as "Cab/Sat", rather than its OEM default of "DTV".
Once you get past the confusion, the benefit is that when mapping ports to a given main input selection, the menu shows you how the physically numbered ports are currently mapped as an aid to determine how you might re-assign them as needed.
Unfortunately, since all main inputs selections are default mapped to their suggested default rear chassis ports and the receiver cannot tell which are physically and truly being used, it takes a bit of patience to review your input configuration to ensure it hasn't been inadvertantly mangled.
One rule of thumb that helps me better understand and configure my I/O port mapping is to simply ignore the "device" labels on the read chassis like "DTV", "Cab/Sat", or "DVD". Instead, focus only on the letter/number label of the port such as "HDMI Inp 1/2/3", etc, because they NEVER change and always refer to the same physical port on the rear chassis. Some of the ports of other connection types are labeled using letters, "A/B/C".
Because the usage of the ports changes as soon as you do a re-assignment, the chassis labels are ONLY valid if you NEVER re-assign a port. As soon as you do, they are invalid because the chassis labels are just that - fixed printed labels that can't change to reflect your reassignmenrt. .
I am contemplating setting all unused port mappings of main input selections to "NONE" to make the review process easier. That would also eliminate the problem of dealing with multiple connections such as when you have both HDMI and Component cables connected at the same time. To ensure one is used over the other, set the port of the unwanted type to "NONE" rather than depend on the reciever selecting one by whatever priority it might use.
So, to verify one's current input selection port assignments to ensure that all is set as needed, let's use an example HDMI connected Cab/Sat box by doing the following:
- Inspect HDMI connection between Receiver & Cab/Sat box
- Check which HDMI Inp is used on the Receiver. Def = "Inp 3".
- Invoke receiver's on-screen configuration menu
- Ensure it shows "Inp #" where "#" is the port being used on the rear chassis.
- Then review all the other input types for Cab/Sat such as Component, Optical, Coaxial, etc. Although not necessary, if you are not using other input ports for Cab/Sat you could set them to "None" to better reflect the reality of your physical connections. That also makes it easier, in the future, to identify unused ports and also eliminates any confusion as to which port the receiver will end up using. When all are set to defaults, you can't be sure.
It took me several weeks of head scratching to get a feel for how it all works and, in the process, doscivered I had some bad assignments that mysteriously made certain inputs appear as dead. The manual really doesn't cover this stuff very well.
The unknown, once learned, is usually obvious :-)
