If they are to different display devices running at the same time the one with the reported lowest resolution will be the resolution sent to both display devices, as you cant send independen resolutions to each display @ the same time..

If you have the splitter placed at the HDMI output of the Blu-Ray player and split one to Onkyo and one to Display you will only get
the Audio that the Display device reports so with Moome you will get Standard Lossy Dolby and DTS..

If you Split at the Onkyo HDMI output you will get all the audio codecs but due to pass through in the Onkyo the Picture will be slightly degraded less quality..

Keep in mined that this Discussion has nothing to do with HDCP it is to do with EDID, I was only pointing out HDMI Splitters/Matrix inherent issues ...

So by adding one of these splitters/Matrix won't quere the issues you Discribe, regarding the question you asked about "if adding A HDMI matrix will solve your problem"....

Of course you getting HD codecs because your not splitting 1x2 at the Blu-Player HDMI, your stripping the audio out with the Onkyo first then going to the Display device..

Please re read 2 posts above your post..

Finally, I got a picture with the following connection: PS3/BD30 --> Onkyo905 --> 4x2 switch splitter --> ext V2 box --> Barco 1209s. Interestingly, only one of the output from splitter works but not the other! The HDMI/ HDCP are so difficult to understand.

But now I has a new problem. When HTPC (1080p/60)was connected to the ext V2box, it showed a good image just fit the screen. When I connected BD30/PS3 (1080p/60) to the another input of the ext V2 box, the image shift to right hand side. Then I adjusted the image position to the centre according to the menu (press the select button with SW1 #5 at K side). When I switched back to HTPC, the picture moved to right side! But according to the menu, 'Shift value will store in memory for each factory default resolution when power off, and shift value will be loaded at next power on'. But why do I need to adjust repeatedly? And although both resolutions are 1080p/60, the frequency displayed on my projector is slightly different. Any solution to it?

Congratulations on the picture finally, Sulley.

The HTPC is using computer timing for 1080p, and the BD30 is using video timing for 1080p. The timings are slightly different (1080p/60 timing for computers is exactly 60Hz, while 60 Hz video timing is 59-point-something-or-other), and cause the picture offset. This is why the projector shows a different frequency for each source, and you have to readjust centering.

Try using PowerStrip on your HTPC. It should allow your videocard to output 1080p at video timings, eliminating the need to readjust centering when switching sources. You also might see if your video card's drivers allow custom timings, which will eliminate the need for PowerStrip.

OK, I found these in a posting in the HTPC area of the AVS Forum. They are for 1080i:

"...33.75KHz scan rate and 59.94Hz refresh rate...".

EDIT:

One more set I found later in the same thread. This one is for 1080p, and the poster is describing the 1920X1080p input frequency specs listed in his TV's manual:

............................H-Freq.....V-Freq....PixelClock...H-Sync...V-Sync
Specification...........66.587.....59.934....138.500.......( + )......( - )

Good luck! Very Happy

I thought with power Strip you could move the picture left, right up, down thus Changing the timings while doing so ?...
That way you could center the pic in the raster while leaving the Projectors RGB shift set at nominal 128..

Rolls Royce brings up an interesting & importent point with standard 1080p timmings in that Horizontal is + vertical is -

I think most PC's would use Vesa H+ V+ by defalt, thus the Projector will try and use A different memory block
because of the Projectors pre calibrated 1080p memory block timming not being H+ V- for PC if the projector
was setup using Blu-Ray players input signal ..

Thanks for sharing that Royce Thumbs Up
