Charbucks Posted July 27, 2007 Share Posted July 27, 2007 I did a search, and I can see that several people are having the same problem: the computer thinks that it is displaying "millions" of colours, but it's pretty obvious that it's not. Nvidia people seem to have some sort of solution - is there anything I can do other than switching to analog? I'm running uphuck 1.4i, ATI 9600 pro with callisto 008 + AGPgart, and I'm connected to a 20" LCD via DVI running at 1680x1050x60 (although the resolution settings says 59.9 Hz, not sure if that's related though).

rathalos Posted July 27, 2007 Share Posted July 27, 2007 Well, apparently it might be a hardware issue with your monitor... As far as i have read on many forums, including apples, the LCD panel monitors are mostly 6-bit colour monitors... That means it can disply only up to 6-bit of colours.... What apple does is to use dithering technology to smoothen things out and make it appear as if the LCD can display millions which is 8-bit... Hence, you can see colour banding on your screen (cos of bad dithering)....

OMX-Knuckles Posted July 27, 2007 Share Posted July 27, 2007 It's the monitor. What make is it? Cheaper LCD's have terrible colour reproduction. Even my Samsung panel has issues sometimes.

Charbucks Posted July 27, 2007 Author Share Posted July 27, 2007 Pretty sure it's not the monitor - I bought it specifically because it is a true 8-bit display. It's a viewsonic vx2025wm with a pMVA type screen and I'm pretty sure it is *actually* 8-bit. This specification is listed on the viewsonic europe page (although oddly enough, not USA): http://www.viewsoniceurope.com/UK/Support/...VX/VX2025wm.htm - "Colour Depth: 16.7M colours (8-bit)" Compared to another monitor: http://www.viewsoniceurope.com/UK/Products/LCDX/VX2235wm.htm - "Colour Support: 16.2M colours (6-bit+2-bit FRC)" So it would appear the viewsonic is honest in their description of colour support. Also, I've looked at various test images that are supposed to determine whether you have a true 8-bit display or whether it's dithered 6-bit - they look awesome in ubuntu and terrible in os x.

Charbucks Posted July 31, 2007 Author Share Posted July 31, 2007 Bump for help... any other thoughts besides hardware? Link to comment https://www.insanelymac.com/forum/topic/58218-colour-banding-not-actually-32-bit/#findComment-418127 Share on other sites More sharing options...
OMX-Knuckles Posted July 31, 2007 Share Posted July 31, 2007 Try running games that use 32-bit colour. Mess around with colour profiles in the Control Panel too... I haven't had an issue on my laptop's panel (looks fantastic) nor my desktop's Samsung panel.
