Chrysaor Posted April 15, 2006 Share Posted April 15, 2006 Same thing here. Although System Profiler says 32-bit, i have 16 bit color and experiencing banding. Using Dell Inspiron 9300 laptop with NVIDIA Geforce 6800 Go. (OSX 10.4.5) Is there any fix to this? Link to comment Share on other sites More sharing options...

Chrysaor Posted April 15, 2006 Share Posted April 15, 2006 Connected my laptop to a CRT monitor and banding is gone. It solves the issue. I guess LCDs connected with DVI (including laptop LCDs) are running at 16bit mode for some reason. http://www.deviantart.com/view/6248662/ If you see banding at the sky with this pic, you are running at 16bit mode. najt; Yes, i am using macvidia b1b5 drivers, but the issue is not with macvidia drivers, i had this same thing before with VESA drivers.

macprodan Posted April 15, 2006 Author Share Posted April 15, 2006 Thats an Awsome wallpaper. Looks so nice now, where as before it would have been unusable due to Color banding. Link to comment Share on other sites More sharing options...
blinksilver Posted April 15, 2006 Share Posted April 15, 2006 its nvidia related, I noticed it for the first time in linux. When I ran the X.org native "nv" drivers I got "color banding," when I switched over to the drivers written by nvidia it went away. You might want to talk to np_ about it. See what he says. I think it maybe as simple as dithering is turned off, or it maybe something far more complicated. Link to comment Share on other sites More sharing options...
Chrysaor Posted April 15, 2006 Share Posted April 15, 2006 I don't think its NV related, since first 2 posters experienced same with ATI cards. Also, using analog instead of digital monitor connection solves the problem for both NV and ATI. So i guess the problem is with the monitor connection. I hope it has a simple solution, since 16-bit display looks really ugly with OSX. Already talked with NP_ about this, he said it might be hardware issue. He suggested it might be because of RAM but my RAM runs without any errors, just ran memtest86+ and passed. Anyone who uses LCD connected with DVI or laptop LCDs (digital connections) please check the picture i gave and post if you see banding. Link to comment Share on other sites More sharing options...
nitrosx86 Posted April 16, 2006 Share Posted April 16, 2006 I've got the same problem, I see banding with my laptop LCD. How I can to fix this? Link to comment Share on other sites More sharing options...
Chrysaor Posted April 16, 2006 Share Posted April 16, 2006 I've got the same problem, I see banding with my laptop LCD. How I can to fix this? Only known workaround is using analog connection instead of digital. For laptops that means connecting to a CRT monitor. Anyone have any idea what is causing this? This is serious issue effecting everyone using laptops and DVI LCDs. Link to comment Share on other sites More sharing options...
sigxcpu Posted April 16, 2006 Share Posted April 16, 2006 same banding using DVI on ATI X600. No banding on VGA output. Link to comment Share on other sites More sharing options...
Chrysaor Posted April 17, 2006 Share Posted April 17, 2006 Its interesting that many people are running at 16-bit color depth and not noticing this. Pretty sure everyone using laptops and LCDs with DVI are affected by this. Link to comment Share on other sites More sharing options...
Ender Wiggin Posted May 24, 2006 Share Posted May 24, 2006 I also have this problem on ATI Radeon 9550. But it seems to me that the problem is somewhere inside the OpenGL driver. Most video apps, like VideoLAN & FronRow (and QuickTime i think) use the OpenGL interface for rendering video files. What if OpenGL only works in 16 bits? Or could it be that our LCD displays are not actually rendering 16 mil colours and in VGA mode they adjust, but in DVI mode they don't convert the colour information?

djeglin Posted June 10, 2006 Share Posted June 10, 2006 Anyone got any closer to figuring this out yet? Nothing seems to have been posted in quite some time, and I'm anxious to get my Apple Cinema display running to its full potential Any help much appreciated.

cool0221 Posted October 13, 2006 Share Posted October 13, 2006 People: if you use a DVI connection and notice grainy/dithered wallpaper, you are running osx86 under 16bit mode although it says 32 bit! I have the same problem here. Profile: 10.4.7 JAS DVD Dell 4550 with P4 2.4 GHz CPU + ATI 9800Pro 128Mb + 768Mb RAM There is lots of color banding via DVI Solution so far: connect via VGA analog, problem goes away Does anyone using DVI not have this problem? Could you share your system profile with us? Thanks! Cool Link to comment Share on other sites More sharing options...
cs_lyxaa Posted January 21, 2007 Share Posted January 21, 2007 If Macbook Pro is having the same problem, I think the artists who buy Macbook Pro should ask Apple to solve this problem for them. My DELL XPS M1210 with Geforce Go 7400 is having the same problem. Link to comment Share on other sites More sharing options...
paco_ Posted January 21, 2007 Share Posted January 21, 2007 I had the same hateful problem and have resolved with nVidiaEFI! But I have cancelled all and reinstalled without others video drivers! Link to comment Share on other sites More sharing options...

huntz Posted September 29, 2007 Share Posted September 29, 2007 Well, thanks to paco_. I was a titan user, but this 16bit "bug" it's really annoying. nVidiaEFI (never heard about it, always only titan and natit...) is the MUST HAVE for any mac user! Tested and working with my geforce 6800. Cheers. Link to comment Share on other sites More sharing options...
