Yes, a 2-HDMI output AVR would have the same limitations since there is only one video stream at a time on an HDMI cable. You can't really get around it.

You can bypass the limitation with some of the matrix splitters that can modify the EDID. However, that still means one or the other TV will not get a valid picture (the non-3D will get a 3D picture and not know what to do with it). However, that is an option.

What a 2-HDMI output receiver buys you is less complexity in the handshake which should mean less time. But, there is variability in the capabilities of different HDMI chipsets and how handshaking is done. So, there is no way to guarantee that one set of equipment will have faster handshaking without trying it first.

Hello onse

AVR’s do seem to have become a ‘choose it for the features’ product – no mention of sound quality anywhere!!!

‘what kind of extra delay I would be looking when changing the HDMI inputs?’ – fast switching works well though it’s still not instant if you are flipping between Sources outputting a different signal format, which then requires the Display to reset itself and in that case a projector is much slower than an HDTV.

AVR + 1x2 DA – certainly very possible though as Andy points out you can run into EDID and HDCP issues. If you do hit a problem having the ability to update the DA Firmware with custom code is very handy and usually much more practical/customisable than updating the AVR Firmware.

3D + non-3D Display – can cause you problems. Here again having a DA with user selectable and programmable EDID modes can be handy as it will often enable you to ‘Force’ 3D through to your 3D enabled Display even if the non-3D Display is connected and sitting in standby or even powered on.
