g73sw strage lcd issue

G73sw show only with external monitor
I tried with a video card, not for this model, you see only the external display. I bought a new video card (gtx560 ) , and you still see only the external monitor.
I changed the flat, no change.
Then I tried the video card with another motherboard (new motherboard with bios for gtx460 only ) for this notebook model, you always see only externally.
I purchased a new monitor (50 pin 3d full hd 17 ") but with both motherboards is seen only with an external monitor.
This notebook has two connections for the video cable, one for monitor 50 pin 3d and the other for non-3D monitors. The problem is that the system not detect the monitor used and don't send the correct signals.
Another thing I've noticed: any video card I use, works fine with external monitor
although does not have the correct video driver in bios (the new motherboar has only gtx460 vbios I check with mmtools).
It use a generic driver?
it is possible that what we see with external monitor is the video output from the cpu ?
any ideas ?

Re: g73sw strage lcd issue

There was another problem with new video card:
I purchased this as a GTX560 video card (http://www.ebay.it/itm/ASUS-G53JW-G5...00-A03-TESTED- GOOD- / 301894802875), now as you see in the picture the card is for G53JW model, downloading and extracting the VBIOS from asus website I found that this driver is for 10de, dd1 which corresponds to a GTX460M.
The chip welded on this card is N12E.GS.A1 which corresponds to a GTX560M.
So it seems that they did an upgrade and I have serious doubts that are truly 3G vram because I read that GTX460M support max 1.5G vram.
This card has 12 chip hynix h5g02h24mfr (4 Banks x 2M x 16bits Synchronous DRAM)
I thinking it was a real GTX560, I used the driver for a vbios
asus g73sx
At this point what video driver I have to try?

Re: g73sw strage lcd issue

the ebay link has changed:
http://www.ebay.com/itm/ASUS-G53JW-G...-/292049352391

There is a pm25ld010 with a vbios instead on new GTX560m and on old GTX460M, but there is a vbios also in motherboard bios, which vbios is used by the system ?
