reilley Posted July 21, 2008 Share Posted July 21, 2008 Quick specs: HP dv9233cl notebook with 17" LCD at 1440 x 900 Kalyway 10.5.2 From System Profiler: G73 GeForce Go 7600: Chipset Model: G73 GeForce Go 7600 Type: Display Bus: PCIe PCIe Lane Width: x16 VRAM (Total): 256 MB Vendor: NVIDIA (0x10de) Device ID: 0x0398 Revision ID: 0x00a1 ROM Revision: NVinjectGo 0.1.0 Displays: Display: Resolution: 1440 x 900 Depth: 32-bit Color Core Image: Hardware Accelerated Main Display: Yes Mirror: Off Online: Yes Quartz Extreme: Supported Rotation: Supported Display Connector: Status: No display connected I am seeing video "banding" with any gradients in documents, videos, etc. I have searched the forums using "banding", but posts referring to this problem are somewhat dated. Has anyone else experienced this and if you have resolved it, how? I am backing up my system now and plan to run Leopard Graphics Update, but I have doubts that this will resolve my problem. And just in case anyone asks, I do not have this problem when booted in Vista. Gradients are perfect there. Link to comment Share on other sites More sharing options...
reilley Posted August 4, 2008 Author Share Posted August 4, 2008 That's the thing - I never got rid of the video banding and I guess no one else did either. Argh... Link to comment Share on other sites More sharing options...
Krazubu Posted August 4, 2008 Share Posted August 4, 2008 Some thoughts : -Your colors are set to 65536 or below -Your screen doesn't support more colors -Your screen is not detected properly, try to inject the EDID manually -Video driver is not set to dithering mode whereas it should be (a dithering value to set to 1 inside the injecter) Link to comment Share on other sites More sharing options...
reilley Posted August 4, 2008 Author Share Posted August 4, 2008 OK, that's good information, but where do you set these items? I have display colors set to "Millions" in System Profiler. I don't have this problem in Vista, so I'm sure my display will display more than 64K colors. How do I inject EDID manually? Is there a setup or configuration that I don't know about?

stanleycup_ch Posted August 5, 2008 Share Posted August 5, 2008 Hey I got the same card as you(Go 7600 256MB). How did you make it working? PLEASE!!! I've tried tons of NVinject versions/NVCAP combinations and I always get a black screen or a kernel panic. Can you just tell me what NVinjectGo version you used and with which NVCAP?. And did you changed something other than the NVCAP in the plist of the NVinjectGo.kext? What kexts did you use? I'm desperate and tired of the {censored}**** 1024x768 crappy resolution! Please HELP ME!!!! How did you make it working??? Link to comment Share on other sites More sharing options...

reilley Posted August 5, 2008 Author Share Posted August 5, 2008 But my card is only 256mb - should I use Go 0.2.0b that is NOT the 512mb version? Link to comment Share on other sites More sharing options...
reilley Posted August 13, 2008 Author Share Posted August 13, 2008 Ok, I installed NVInjectGo 0.2.0 using the installer and the problem was not resolved. I tried both the 256 and the 512 version of the 0.2.0b installer and never made any difference. I am out of ideas, so if anyone else has this card in a notebook computer like I do and have had success with resolving the banding issue, I'd love to hear from you! And thanks for everyone's assistance thus far - I really appreciate it! Link to comment Share on other sites More sharing options...
