    Hello !!

    - I use a Shuttle sn41g2 v2 (it contains a NVIDIA GeForce2 chipset) with a cv22 DVI AGP Card.
    - My OS is XP Pro sp2
    - I have a Sanyo PLV Z2

    I have some problems :?


    I use a Nvidia Driver (66.93, the latest)
    I put "Auto mode selection" for Full Screen playing in settings panel.

    The best mode is to use DualView ... I think.

    I have a lcd (main monitor, 1024x768,60Hz)
    I want to use my PLVZ2 at the maxi resolution (1280x720)


    I did these tests:

    A**** Sanyo is the secondary monitor!
    1/ play a HD 1280x720p file
    ok, Sanyo plays .... but at D-SVGA (800x600)
    If I use the 4:3Normal screen, i just have a little image :(
    I must Zoom to fill my screen :x


    2/ play a DVD
    Seems to be OK ... of course, comparated to HD, DVD is poor format:
    800x600 + zoom is enough

    B**** Sanyo is the main monitor!
    I succeeded in creating a custom settings in NVIDIA but... all darkest parts of picture seems to be "in the matrix ;) " => little green lines are blinking !



    I went to these links:
    - http://www.entechtaiwan.net/forums/viewtopic.php?t=267
    - http://entechtaiwan.net/forums/viewtopic.php?t=459

    Ok, I use powerstrip ; but My Sanyo seems to try D-XGA and .... fall again & again in D-SVGA

    MonInfo gives me a strange result :
    3 Monitors :
    1 Nvidia...GPU
    1 Nvidia...GPU2
    1 Sanyo



    Did someone already see these phenomenon ?
    Did you find a solution ?
    Powerstrip is a layer over Nvidia.
    Which one do I customize ? Powerstrip? Nvidia ? nvidia first ?



    I'm losing my mind ....
    Anyway, I can use my Z2 but I cannot sleep quietly because I know that it can do better ;) ;)

    If someone could guide me ... it should be great :)

    SeeU!

    nb: If I succeed, I write all my settings in a post in order the others could read it and never become craziest than me :!:

    Are you getting your desktop running at full res (ie 1:1 mapping) on the Z2 when its your second monitor?

    My LCD Screen cannot reach this resolution :(

    But no problem
    I used Powerstrip in order to customizes my settings => Ok => Now,I can send 1280x720 to my Sanyo Z2 :clap:
    I configured my Card as "DualView"


    I just only have a last problem :
    I succeeded in creating a custom settings in NVIDIA but... all darkest parts of picture seems to be "in the matrix " => little green lines are blinking ! :eek:

    to be continue...

    Maybe your having the same problem i had.

    Is your projector recieving analog or digital DVI input?

    Nvidia drivers have a problem at the moment when running DVI digital, in which they can only select the EDID resolutions, which all happen to be 4:3. A work around i found was to turn off my machine, use a DVI to VGA adapter with my CRT plugged in. This forces the card to run in analog.
    After windows has loaded, i unplug the crt and adapter, and plug in the projector over DVI, then i can pick whatever resolution i like. 1280x720@60hz works perfectly, no need for powerstrip etc.

    Hopifully that helps some.

    EDIT : now that i think of it, anything using a geforce2 chip is prolly analog anyhow. I guess that would be why powerstrip worked without forcing a virtual desktop.
