First of all when you talk about SBS via PC, HDMI 1.4 is not necessary nor required. That is only for frame packed/sequential 3D. Second when you out a resolution od 1920*1080p on your graphics card the projector will show that no problem. However(I dont say that but current users) the SBS 3D option of the projector is greyed out(deactivated). Other projectors do not do that. Take for instance the Acer H9500BD. The resolutions that it will play SBS taken from the Acer's manual are:
Modes Resolution V.Frequency[Hz] H.Frequency[KHz]
720p (Side by Side (Half)) 1280x720 60 45.0
1080i (Side by Side (Half)) 1920x1080 50(25) 28.1
1080i (Side by Side (Half)) 1920x1080 60(30) 33.8
1080p (Side by Side (Half)) 1920x1080 50 56.3
1080p (Side by Side (Half)) 1920x1080 60 67.5
Clearly states 1080p at 50Hz and 60Hz.
Lets take (again) the resolutions that the Benq W1070 will play SBS(I ignore resolution other than 720p and 1080i/p if you want to see them all please read the manual at Specifications)
Format Resolution Refresh rate (Hz) H. Freq. (KHz) Pixel Freq. (MHz) Aspect
1080/50i*** 1920 x 1080 50 28.13 74.25 16:9
1080/60i*** 1920 x 1080 60 33.75 74.25 16:9
***Supported timing for 3D signal with Side-by-Side format.
Yes there are other resolution including 1080p where the projector can play frame sequential 3D but SBS only 1080 interlaced. So yes the projector is picky and it has nothing to do with the standard of HDMI 1.4. Probably there is a way around this and this is what I am trying to find out before I commit. Hence my questions to the current owners.
