I'm having a hell of an issue, and unfortunately I'm not able to test a theory at the moment: so I come to you guys in the hope that you'll have the answer I've been searching for over 6 months for. My issue is with Color Gradients: specifically with color banding. My EG9100 is a great tv. The Blacks are perfect and contrast is fantastic, but color gradients are HORRID. ABSOLUTELY TERRIBLE. The article you have here seems to sum up my issue perfectly (especially the first images), but I've been in contact with LG lots of times and they say it is a 10bit color depth TV. So, I'm left wondering why my color gradients are so terrible. I've tried: different hdmi cables from different companies, different devices plugged into the tv at different hdmi inputs, modifying windows color profile settings, modifying my graphics card settings (every single setting possible in the nvidia options), modifying the settings on the tv itself (every available option)... pretty much everything I can think of to try and none of it improves the color banding issue. I've finally broken down and called for help from LG and I'm having a service center try and replace the panel or board on it to see if that's the issue. My one theory on it would be that the tv is bad, so I would need another one to test, but I don't have access to another one and don't have the money to get it. I'm worried that replacing the panel and board won't fix the issue...and that would mean the tv just fucking sucks and I'm stuck with it. Anyone, everyone—please en-fucking-lighten me on what to do.
