Quick question here as I m tired of searching every where with no direct specific answer !!
I built my projector with a MST controller which only have 1 HDMI input.
So I plugged my PS3 with HDMI, and my computer with VGA (I know it support 1080p so ...)

A good friend just bought a Samsung 52" 1080P TV and asked me how to plug his PC to it !
I had a 35" VGA cable unused so I gave it to him letting him know that VGA supports 1080P, so he's gonna be just fine !
Then he had to change his graphic card. I bought him a little geforce with HDMI output!
He bought a 25' HDMI cable and I plugged it into his 52" TV instead of the VGA ..
WAOW !!! that is a completly different league !!
I NEED ME PJ TO BE LIKE THAT !!!!
whites are so clear, everything is soooo clear !

So my question is: Can I use a dvi dual link to HDMI cable, plug it into a cheap HDMI switch that will give signal from my PC and PS3 to the PJ ?

I plugged, a year ago, my cousin's PC to his 20" LCD monitor with a DVI-d dual link cable and it didn't worked.. I had to use a DVI-D single link to have it working proprely !

So I m wondering if I m using a controller to drive my panel (MST), will this work with dual link DVI ?
Or it doesn't matter as it will be converted to HDMI ?

And do I have to check some specific specification for the HDMI switch ? (beside HDMI 1.3).
The one I looking at is This one from Ebay , but it says "Frequency bandwidth: 1.65Gbps(single link)" so maybe a DVI Dual link won't work ?

From what I think, DVI-HDMI will not loose any quality, and no matter if it s a dvi dual or single link, it will do the job as its converted to HDMI !
And the switch is just fine, I will not loose any quality either!
I'll just have to be sure to get some good High Speed HDMI cable from the switch to the PJ, a good quality dvi to hdmi, and everthing will be perfect ! (from monoprice)
I will have perfect white like my friend have on his TV !!

Am I wrong ?
Am I missing something ?

Thanks a Bunch !!!

Alright, here is the test I did !

My friend brought a DVI to HDMI cable, and I plugged my computer (Geforce 8800GTS) to the MST controller.
Now, the only resolution that works is 1280x960 (16x10).
If I try setting the Driver to 1080P, it does not work! (but the PS3 is)
Neither any other HD resolutions.
I really need to be set to 1280x960 to get an image !

My Panel is WUXGA so it is 16x10 native 1920x1200.

Any idea how to setup my PC to a HD format to have the projector working properly ?

Thank you very much !!
