This could suggest some kind of resonance with the specific frequencies represented by the effected colors that is causing ringing. Who really knows why it's happening (that could take a billion years on a scope to figure out), but you might be able to mitigate it with a couple of RC filters or an inductor or two. That is, if you are actually looking to clean it up. Also, I would wager that these devices are built with relatively shitty components with less than ideal values to save as much cents as possible. Beefing it up a little bit might improve it a bit.Josh128 wrote:Its interesting. Not all colors are impacted by the issue, several are but some less than others. The primary color blue is definitely the worst. When looking a solid patch of true blue, its almost as if there are no scanlines at all! Light /sky blue is fine, with nice defined lines, but the closer to primary you get, the worse the issue. Primary red is next. There are still visible scanlines, but they are quite attenuated. Magenta is also affected but oddly enough, seems to be a bit better than pure red. Primary green seems to be the least affected, but the scanlines in it are definitely less pronounced than in pure whites , yellows, sky blues, and grays, which are the least affected.
Sorry if I'm being lazy and this was technically explained further back, but it seems like it could be fixed, especially because it's limited to certain colors.
