Screen resolution fix, howto do it at deployment

I discovered that for whatever reason, XP Embedded fails to configure the
desired resolution and refresh rate for some of our LCD monitors (1920 X
1200, 60 hz). I can see the failure in the FBA log.

By observing what happens in regular XP when I clear the "Hide Modes That
The Monitor Cannot Display" checkbox on regular XP, I discovered that if I
go into the registry on my XPE system after it is installed and add a DWORD
entry called "PruningMode" (value of 0) to:

HKLM\SYSTEM\CurrentControlSet\Control\Video\{some guid}\0000

that on the next reboot the XPE system would achieve the proper resolution.

I guess my question is, am I doing this the hard way? If this is indeed a
good solution to the problem, what can I do in a component that will force
this entry to show up in the proper place without me going back and tweaking
it by hand?
 
Gereon,

I see. Then IIRC there is some reg.tweaks available for the RADEON 9x00.

In the component you created out of the driver package, in C2_21277.inf or CX_21277.inf file (I don't recall which one but you can
try both) find [ati2mtag_DEFAULT_SoftwareDeviceSettings] section and add the following line there:
HKR,, PruningMode, %REG_DWORD%, 0

Then redeploy the image. Let us know if it helps.

Btw, are you sure you saw the PruningMode value under [HKLM\SYSTEM\CurrentControlSet\Control\Video\{some guid}\0000] ?
Because I seem to see it under [HKLM\Software\Microsoft\Windows\CurrentVersion\Control Panel\Settings\Video] (getting read by
themeui.dll - "Display Control Panel" component). You can give it a shoot too.

I was able to get this to work by following the spirit of the advice. I'm
using the built- in Windows ATI component for the 9800 Pro, which uses
atiixpag.inf. I force it to install my own copy of the file. It had an
[ati2mtag_DEFAULT_SoftwareDeviceSettings] section, but adding the key to
that one didn't work. But adding it to [ati2mtag_SoftwareDeviceSettings]
did.

Thanks KM!

Gereon,

Ahh.. Sorry for the DEFAULT "bug". I actually meant the [ati2mtag_SoftwareDeviceSettings] section but copied/pasted the DEFAULT one
from the INF file.
I am glad you figured that out :-)

I used INCTRL to detect the change, and that's where it reported it. I
looked in my regular XP install on the target box, and under
[HKLM\Software\Microsoft\Windows\CurrentVersion\Control
Panel\Settings\Video] there is basically only an entry for the monitor.

Just for fun, I'll try it and see if it works too.

Nope, just adding it to the Control Panel\Video key didn't work.
No problem, I have a way to make it happen that doesn't involve hand-
tweaking, so I'm happy. At least, I'm happy about this...

Ok.. Good to know. Then I won't be even thinking about that key from now on. :-)

ATI Radeon Xpress 200 (PruningMode)

[HKLM\Software\Microsoft\Windows\CurrentVersion\Control Panel\Settings\Video]
REGDWORD "PruningMode", 1

Worked for me! ATI Radeon Xpress 200 (was previously detected as a 1100 ???)

Thanx
