blu rays flicker on new 1080p tv

superweld

i just got a 40" lcd samsung 1080p. seems perfect for gaming but noticed on the first two blu rays i watched that there's a slight flicker on some images. not in every scene but quite frequently it's noticable. since it's not there for gaming and not in every scene on a blu ray the tv must be fine.

i've tried changing settings on the tv etc but it's still there.

basically just wondering is this common in 1080p blu rays or what's the story?

superweld

i change the 1080p output setting on my player and the flicker is gone.

it used to automatically detect 1080p 24hz but now i turned this off. the blu rays play at 60hz now and the flicker is gone.

but i was reading that blu ray is supposed to be 24hz ???

am i getting the correct picture?

last year in sept i bought a 46" samsung lcd 1080p and had flickers when playing xbox360 games and hd-dvds. I sent the tv back after a week and got it replaced with a different product altogether. New product had no problems at all .
Bottom line is that flickering picture is a sign of a fault in the tv and should not be tolerated. You are within your rights to return the tv and ask for a replacement or refund.

5 series or 6 series samsung?

bada_bing

i got the 5 series first where the flickering problem occured and then replaced with a 6 series. I had to pay a little bit extra for the upgrade to 6 series. I guess you got the 5 series didn't you??

did you buy it from samsyerman.co.uk by any chance??

From the research I've done, as I intend on buying a 40" Samsung, the flickering is inherent in the 5 series samsung when displaying 1080p blu-ray but when adjusted to 1080/60 as opposed to 1080/24 it's not as noticeable

5 series. purchased in bricks and mortar sale.

i got a replacement and had the same problem so changed it to 60hz and didn't notice flicker. then i assumed it was just the settings?

so do you think i should bring this one back too and get another tv or was it just that the settings should have actually been 60hz?

thanks for the replies

Have you not got an automatic refresh setting?
Some discs will be 50hz (Pal), some 60 (NTSC), some 24(cinema). Higher is not necessarilly correct or best.

i'm using a ps3 so yes. dvds are playing at 50hz and blu rays now at 60hz.

there's an option on the ps3 to automatically detect 1080p/24hz. i had that at auto (default) and there was flicker. when i pressed info on a dvd which looked fine i noticed it was 50hz so turned the auto detect 1080p/24hz option to off. once i did that the blu rays played at 60hz without the flicker.

i just don't know now if i'm just not noticing the flicker or if i'm getting the best picture from my 1080p tv

Read the review which explains the problem:

I doubt they'll let you bring it back and exchange for an different series as it was bought in a sale, you could try though...

"1080p/24 capability (PS3) Accepts 1080p/24 video signal, but judders"

so this tv is a 1080p tv that does not display 1080p properly??!!!

any ideas how much postage would be on a 42 inch from that crowd to waterford?

most low-mid range 1080p TVs experience judder, just some more noticable than others, essentially you get what you pay for - I was gonna buy the 558 and decided to go for the 686 instead although it was more expensive

Just put it at 60Hz and that'll pretty much solve it; it's still a great TV!

isn't 1808p/24 supposed to judder? it _is_ displaying each frame 5 times as the cinematographer intended.

Or is the judder even more pronounced?

superweld

i'd call it flicker more than judder :pac:

sort of rolling horizontal lines as well as judder i suppose

not really noticeable on 60hz. not 100% sure the picture is much better than 1080i though. hard to tell since the new tv seems tarnished because of it

They delivered a 40" set to Cork for someone here for £15 by courier.

I don't get the 5 times thing. Far as I know (and correct me if I'm wrong):

1080p/24=24hz refresh rate of a 1080p film, i.e. full 1920x1080 image displayed at 24fps. As Blu-Rays are natively 24hz, this is exactly as the film was recorded and intended to be viewed.

If there's a slight jump very second, that might indicate that the TV accepts a 24hz signal but displays it at its own native refresh rate of 60hz; the conversion causes a slight jerk each frame as 24 doesn't divide correctly into 60. My Philips TV did this, so I switched the player to 60hz output. Although there's no judder, the frame rate still seems a little "off".

However this isn't a fault of the telly or the retailer, so there's no obligation on the retailer's part to accept a return. Though they might be gracious enough to offer an upgrade.

This kind of thing shows exactly the problem with all this HD ready/Full HD technobabble. How are normal everyday folk expected to understand the meaning behind 1080p/24, Progressive Scan, dts HD etc... argh, major argh...

Not sure if poeple quite understand the 1080/24 problem.

This article explains the problem pretty well.

1080/24 causes similar issues in some entry level 720p & 1080p projector which has been addressed by improved technology in the more expensive models.

This is the same in flat panels.

wish i'd known this sooner or i would have stuck to my 1080i tv as blu rays were stunning on it. the average joe would only assume the 1080p to be better! my 1080i was not top of the range either. cheapest available when i got it.

on the flipside regular dvds are stunning upscaled on the new tv. life is not meant to be simple is it.

Nope. Then you have 100hz and even 200hz TVs. You have dynamic contrast and native contrast. You have the type of backlight, you have the bitrate of the picture versus resolution, you have ridiculously complicated standards of HD audio (dts core, dts hi-def, dts master audio, dts arrrggghhhhhh), and guess what, Super Hi Vision/UHD is on its way...

http://en.wikipedia.org/wiki/Ultra_High_Definition_Video

In the end, 720p satisfies 99 percent of people on 32 or even 37 inchers. Larger TVs still look OK with 720p. I think the 24p refresh actually looks odd, I have picky eyes and I can see where there should be extra frames. The cinema uses 48hz playback you see, double frames, so it looks somehow smoother. I think sticking with 60hz output and letting the TV do the processing looks the most natural IMHO.

The article linked explains it far better than I can, but the way I saw it explained was that certain technologies (eg bravia engine) ran 1080p as 5 sequential versions of the same frame, roughly equating to 120 hz and 3 for 60hz. Of course this is all NTSC multiples, PAL gets 4 frames for 100hz and 2 for 50hz.

These are all dependant on the tv manufacturer and how ever many stickers and formats they want to claim to handle. Reality has it though that each tv really only displays 1 size and format *always* eg 1080p @ 100hz regardless of the DVD format sent to it.

Hence why we need av processors with lip sync delays.
