    Are there any owners of d900c/np9260 with possible acess to a dual-link monitor like the 30incher (2560x1600) displays to test out if the DVI port of the clevo is actually dual-link or not...

    Thanks

    Look at the pictures. If you see two DVI ports, then it is.

    Actually, thats not how it works... especially for notebooks.

    You can have a single DVI-port to support Dual-Link.

    [​IMG]

    * DVI-D (digital only)
    * DVI-A (analog only)
    * DVI-I (digital & analog)


    The only notebooks that is confirmed to have Dual-Link DVI are:
    - Apple MacBook Pro
    - HP Compaq 8510p
    - Clevo M570RU (Sager 5790) :D

    My 9260's DVI port looks like the DVI-D(Dual Link) just by looking at the back. How can I test it Gophn? My HDTV doesn't go too high and my desktop LCD is old and cheap :p

    I believe that the Clevo D900C/D901C is not Dual-Link.

    - Supports 2048x1536 external monitor resolution (resolution can not be higher than laptop)
    ... meaning (in real world use) that it tops out at 1920x1200 (WUXGA) or 1920x1080 (HDTV)

    2048x1536 at 85Hz is the standard max resolution support over the analog 400MHz RAMDAC... by reducing the blanking and setting the frequency to 60Hz... the analog RAMDACs can surpass the dual-link dvi in terms of infomatinon bandwidth... however the signal is susceptible to noise.

    The quote refers to both analog signal carries by both the vga and dvi port on the laptop...

    Single-link dvi has the maximum bandwidwidth of 1920x1200@60Hz (with a little extra MHz left)

    Almost all female dvi ports on most monitors will look like the DL-DVI (DVI-D)port but the 6 additional pins will not be connected in non-dual-link monitors...

    Almost all female dvi ports on most graphic card will have holes for DL-DVI and the additional 4 analog signals (DVI-I)...

    so the only way to be sure would be to test on a 2560x1600@60Hz DL-DVI monitor or a specific written statement from the manufacturer...

    p.s. The Eurocom clevo d900c derivative is advert.. as DL-DVI capable... but still no first hand comsumer experience just to be sure....
