Hello!

I'm very new in Windows CE .net and should configure a
CE .net with the Platform Builder to run on a small-PC.
This works well, but only in 640x480 Screen Resolution.

Is it possible to change the screen resolution to
1280x1024? I'm using an VIA Board (on Board Graphic) with
CE .NET 4.2 Drivers for that board.

I haven't found an option in the platform builder.

thank you very much!

change your screen resolution.

Hi!
Thank you for your answer.
In the common.reg there is one Section
"[HKEY_LOCAL_MACHINE\Drivers\Display\MQ200]"

Thats the only position where I can find a field
called: "CxScreen" and "CyScreen". So I changed this to:

;; 1280x1024x24
"CxScreen"=dword:500
"CyScreen"=dword:400
"BPP"=dword:18
"Freq"=dword:3C

I compiled, and installed the nk.bin Image, but the
device only shows 640x480 with 256 colors. :-(
I use the origional VIA Drivers for Win CE .NET 4.2 and
he supports that resolution.
Can you post your part of the commmon.reg with that
section?

Thank you very much!

Hey

I am using another driver form via i think. You can try
this:
[HKEY_LOCAL_MACHINE\Drivers\Display\Via]
"LoadBIOSVGASet": VGA registers initialized by VGA VESA
BIOS.
0: disable (default)
1: enable

NOTE: if this registry key is enabled, The registry
keys "CxScreen","CyScreen", "Bpp" are invalid. The display
mode is determined by the boot arguments specified in the
option /L: of "Loadcepc.exe".
ex. If 800x600x16bpp mode is intended, then run
loadcepc.exe with,"loadcepc /L:800x600x16 NK.BIN"
The display modes supported are described in the before-
mentioned paragraph "4. Feature descriptions".
When this registry key is enabled, all the VGA registers
are set by VGA BIOS, but not by the driver.

Hope it will help

thank you for your help!

I think this device don't love me ;-)
I tried "loadcepc /L:1024x768x16 NK.BIN" but is has still
800x640.
And i tried
--schnipp---
IF BSP_DISPLAY_VIA
[HKEY_LOCAL_MACHINE\System\GDI\Drivers]
"Display"="ddi_via.dll"
"CxScreen"=dword:400
"CyScreen"=dword:300
"BPP"=dword:10
; "Freq"=dword:3C
ENDIF
--schnipp---

in the common.reg

thanks!

What for chip are you using?
I have got 2 different via display driver and they work
different for setting the screen resolution.
I did not found this option in the platform builder too.

It's a VIA CLE266 (north bridge) and a "Integrated
CastleRock graphics with MPEP 2 decoder"

I'm very confused... :-/

thanks!
