Monitor not using full colour palette
Aug 27, 2012

My Dell 2209WA (uncalibrated) is not displaying full 16.7 million colours even at 32-bit colour setting. More like a few thousand colours at best. Posterization is most noticeable in monochrome images, where I see like a dozen shades at most instead of 256. Even blue skies look really blotchy. How do I fix this?

The colour was fine when my comp was using Vista. I changed to Windows 7 maybe like a year or two ago. I have not taken or edited any photos since then and now that I am trying to get back into photography, I just noticed the problem. Today, I have updated the drivers of my video card (ATI 4670) and disabled Adobe Gamma (which was only installed a few days ago and was not used anyways) but the problem remains.
