Strange flicker (sort of) - Blu-ray Forum

romac · 04-20-2008, 04:43 AM

This isn't the same traditional flicker problems or resolution lines I've seen on the net with HD sets, so it'll be hard to explain. I have a 47" 1080p Philips LCD, the picture quality is great, but I've noticed on a couple blurays a weird lighting/flicker issue. For instance, in 300 when the Spartan is saying "then we shall fight in the shade" the sky is fairly intense color/light but the clouds are dark, and in the clouds is a weird grainy white flicker. There are several instances like this in 300. Also in Planet Earth on Blu, during a sunset in which intense color is reflected in the water while white birds are migrating overhead, as the picture fades, that same weird grainy white flicker appears for a couple seconds where the water is.

Could this be something to do with the tv's features? It has several that auto-adjust for lighting, perfect pixel hd, dynamic contrast etc. I'm ok with electronics but I'm by no means super tech savvy, so I'm not sure what could be causing it. But the picture is so good and I've had absolutely no other problems with it, it just seems to do this during scenes where theres a strange mix of color/contrast or something (I guess).

Any ideas on features I should disable during these movies?

you should disable most likely all features.

have you calibrated your set in any way?

crackinhedz · 04-20-2008, 04:47 AM

what Bluray player are you using?

Try turning down your contrast a bit.

romac · 04-20-2008, 04:58 AM

It's a PS3, and nope I haven't calibrated anything (don't even know how lol). Most/all features are set to on or automatic. What would be a good number to set the contrast too?

I'm new to HDTV, just bought this about 3 weeks ago and I've watched more movies since then than I have in the past 2 years lol.

Thanks for the help, I'll give it a shot.

crackinhedz · 04-20-2008, 05:07 AM

do you have any of these models?

romac · 04-20-2008, 05:17 AM

Yep it's the 47PFL5432D/37.

re-calibrate your system it sounds like you did wrong. also check your HDMI cable.

crackinhedz · 04-20-2008, 05:22 AM

try out those settings...it may not be ideal, but would be closer than factory presets possibly.

romac · 04-20-2008, 05:27 AM

Trying the settings as we speak, I'll update soon as I get em in.

romac · 04-20-2008, 05:34 AM

Barely there to gone with those settings. Thank you so much

crackinhedz · 04-20-2008, 05:47 AM

no problem.

also keep in mind sometimes there is grain in films...especially in 300. There is no real way to completely remove it as it was placed there intentionally by the director of the film. So try not to worry to much about it.

romac · 04-20-2008, 05:56 AM

Yea I know theres grain, especially for 300s comic book-esque style. Just the flickering white grain was driving me nuts, but it was extremely noticeable. I can still see a very faint hint of it on the new settings, but only because I'm looking for it. My wife/friends etc will probably never catch it now unless I point out where to look.

yeah, the settings might not be precise for you. You should still calibrate the set.
