No 16:10-Resolution with 4870 on VGA-TFT

[Hessi]

Hello,

 

my system is C2D 2.0 on ASRock ConRoe1333-D677 (BIOS P1.30). iAtkos V7 updated to 10.5.8.

 

For more than a year I used onboard GMA950 without any problems. Several days before, I buyed a Asus EAH4870 (512). It works perfectly on a small DVI-TFT, but doesn't recognize a 22" VGA-TFT. It's connected via DVI2VGA-Adapter and a VGA-Cable. Both are able to handle a DDC-signal.

 

Profiler tells me on the small Monitor:

Chipsatz-Modell: ATI Radeon HD 4870

Typ: Monitor

Bus: PCIe

Steckplatz: Slot-1

PCIe-Lane-Breite: x16

VRAM (gesamt): 512 MB

Hersteller: ATI (0x1002)

Geräte-ID: 0x9440

Versions-ID: 0x0000

ROM-Version: 113-B7710C-176

EFI-Treiberversion: 01.00.318

Monitore:

SyncMaster:

Auflösung: 1440 x 900 @ 60 Hz

Farbtiefe: 32-Bit Farbe

Core Image: Hardware-unterstützt

Hauptmonitor: Ja

Synchronisierung: Aus

Eingeschaltet: Ja

Quartz Extreme: Unterstützt

Rotation: Unterstützt

Monitoranschluss:

Status: Kein Monitor angeschlossen

 

QE and CI are activated.

"A monitor isn't connected" – strange.

 

I've tried several kexts and read most of the threads here and anywhere. Actually I lost track of installed versions.

Kextstat tells me:

...

73 4 0x2e13c000 0x1d000 0x1c000 com.apple.iokit.IOGraphicsFamily (1.7.3) <17 7 6 5 4>

...

84 0 0x345fc000 0xcd000 0xcc000 com.apple.ATIRadeonX2000 (5.4.8) <82 73 17 12 7 6 5 4 2>

...

86 0 0x2e312000 0xb000 0xa000 com.dong.driver.ATY_Init (1.0.0d1) <17 12>

...

88 0 0x3d223000 0xc5000 0xc4000 com.apple.kext.ATY_Motmot (5.4.8) <82 73 18 17 6 5 4 2>

...

 

I've added 1680x1050x32 to boot.plist without effect.

 

I'm going crazy!

Any hints?

 

TIA

Regards

Michael

I've added also a kernel flag for the resolution, but without effect! :(

Now I'm in trouble, cause my son takes back his 19" DVI-Monitor.

Im sitting in front of a 22"-Monitor , starring at 1280x960 and going crazy.

 

Please, give me a hint!

 

TIA

Finaly, I've used netkas 10.5 http://netkas.org/?p=271, set Graphics Enalbler to yes in boot.plist.

Now I've got a 1680-Resolution.

 

Systemprofiler shows a "ATI HD 4800", have no idea if it will cause perfomance-issues. Guess I have to boot with Win to play games.
