hi i m back,

now i had implemented my usb display gadget and it works fine in winxp well.

i have few problems currently

my RGB bytes are swapped one , it always invertes blue and red…i m giving the mask bits for colors but doen’t makes an effect on data… is there any other configuration except the bits in video mode information structure…

another things ,

i had developed this driver using windows 2000 Display driver model , will it work on higher version of windows OS or i need to switch to vista display driver model ???

any guidance is mostly accepted …

Are you setting the GDIINFO ulPrimaryOrder value?

It will work, although you won’t see the “Aero” 3D desktop effects. If
you switch to WDDM, you’ll need Direct3D support.

yes i had given ulPrimaryOrder PRIMARY_ORDER_CBA ( my order is BGR byte 0 is B,1st is G and R is 3rd one…) and also masks accordingly

hi my display driver wokrs well in xp but when i move for vista then i faced following problems:

  1. my adapter came in device manager under display devices branch…and also shows the two installed drivers (gdi display driver and miniport driver) and drivers instlled successfully, its status was working properly.

but when i am opening display settings it doesn’t shows my adapter device in monitors list.

  1. i had seen debug messages and found that my miniport driver was called by kernel but my GDI display driver didn’t get any call from kernel as getting call in XP

what may be the problem ,

my installation file is as follows :

I’m not a specialist in display drivers, but I believe it’s been reported
that WDDM and XPDM display drivers can’t coexist. Since your driver is from
XP, it must be a XPDM driver.

Vista I believe also doesn’t support two WDDM display drivers for different
kinds of display adapters. Windows 7 I believe does support two WDDM (1.1)
display drivers for different hardware, but still not a WDDM and a XPDM
display driver.

I looked into the effort to write a new WDDM driver a little while ago, and
it seemed quite likely to be a VERY large project. I believe both Vista/Win
7 can still use a XPDM driver if it’s the only display adapter, although you
won’t get Aero display, or any of the other WDDM features.

I believe Vista/Win 7 don’t officially support USB display adapters,
although you should do your own research on this.

thanks jan,

you r right in vista and win7 xpdm and wddm can’t live at a time.

so , i tested it by disabling currently wddm in vista and win7 and it works as expected one…

but now i did another test on multipoint OS and can’t figure out how to do same thing ( disabling existing wddm and usb display driver ) to enable our usb monitor … and i also dont know whether it will support xpdm or not???

because my main goal is to make it work on multipoint os…

thanks in advance for any suggestion…
