[QUOTE="ssebeny, post: 927711, member: 127823"] Hi, I have a PowerMac G4 (933 Mhz, QuickSilver 2002 model). It came with an nVidia GeForce 4 MX graphics card in the AGP slot which has ADC and VGA ports. I have had an Apple 17" LCD attached to the ADC port on it for years, and recently I wanted to attach a second display (HP w2408) using DVI rather than VGA. After investigating various PCI graphics cards with a DVI connector I passed on them since they wouldn't support Quartz Extreme. Therefore, I decided to purchase basically the exact same nVidia GeForce 4 MX card which was already in my G4 except a version which had a ADC & DVI port on the card rather than the ADC and VGA ports that the existing card has. Unfortunately, after installing the new card, only the display connected to the ADC port seems to be working. The card shows up in the Apple System Profiler properly, and it even list both displays attached. However the display attached to the DVI port will only list "No Input Signal" on screen. This is what Apple System Profiler shows: NVIDIA GeForce4 MX: Chipset Model: GeForce4 MX Type: Display Bus: AGP Slot: SLOT-1 VRAM (Total): 32 MB Vendor: nVIDIA (0x10de) Device ID: 0x0172 Revision ID: 0x00a5 ROM Revision: 1121 Displays: Apple Studio Display: Display Type: LCD Resolution: 1280 x 1024 Depth: 32-bit Color Core Image: Not Supported Main Display: Yes Mirror: Off Online: Yes Quartz Extreme: Supported HP w2408: Resolution: 1920 x 1200 @ 60 Hz Depth: 32-bit Color Core Image: Not Supported Mirror: Off Online: Yes Quartz Extreme: Supported Does anyone have any suggestions as to why I might not be getting output to the second display attached via DVI? I've tried various resolutions & refresh rates via System Preferences, etc. Any suggestions are appreciated. Thanks. [/QUOTE]
