This may be a really dumb question; my only excuse is having recent shoulder/bicep surgery with no tolerance for strong narcotics. Ouch !
I have an rx-v1800 7.1 setup with DTV/BRay/PS3 HDMI inputs and HDMI output to a Sony Bravia KDS-60A3000. Retiring the Bravia because lamp replacement is about every 3 months now. Great TV in its day...
Just bought Sharp Quattron 70" 2D model LC-70LE734U. This set refreshes at 120hz, combined with some backlight scanning, to produce a max of 60fps for fast moving images (not really full 240hz as the 240 AquoMotion ads might suggest).
The bravia can display 60fps primarily because each dot in the RGB pixel grid has its own processing unit.
I think that there is no need to upgrade the yamaha which claims an output HDMI passthrough signal of 60hz because the refresh rate is handled by the monitor and not by the AVR (and isn't part of the HDMI spec anyway).
So, shouldn't I be able to unplug the output HDMI to the Sony, send it to TV heaven and plug into the Sharp despite the monitor refresh rates differences (i.e. the AVR wouldn't be a bandwith bottleneck)?
I don't need stereoscopic 3D or ethernet over HDMI, so I believe the 1.3a HDMI of the Yamaha should be OK. The 1.3a spec includes a wide color space, but I don't think that the extra yellow subpixel would cause a color resolution issue that this spec can't handle....
Any thoughts appreciated--especially those confirming that the rx-v1800 is up to the task of supporting my new Quattron

Thanks and excuse any confusion over refresh and frame rates.
Ouch,
Eric
