Γεια σε όλους,
Έχω την LG 50PG6000.
Έχοντας έντονα σπασίματα στην αναπαραγωγή Blu-Ray και mkv στα 24p (όπως είχα γράψει και στο post μετά την αγορά) έψαξα παντού για το τι μπορεί να φταίει. Τι 60Hz τη βάζω τι 24 παίζει το ίδιο. Έπεσα λοιπόν πάνω σε ένα post που κάποιος έγραφε για το συγκεκριμένο πρόβλημα και πήρε απάντηση από LG.
Παραθέτω λοιπόν τα 2 posts που βρήκα
Hi guys,
I recently purchased an LG 50PG6000 plasma TV which I am farely happy with. However, I have one real concern. The 1080/24p playback judders via media centre and PS3 Blu-Ray. Can anyone confirm if this set actually does proper even pulldown? LG have advertised on their site that it does 3/2:2 pulldown. I dont know exactly which one this means. If it does 2:2 pulldown then the playback should be smooth, but it judders far too much. It's actually quite annoying. Setting the pictue back to 60Hz produces pretty much the same effect. My question is, does the LG PG6000 range convert 24Hz back to 60Hz, making 24p support effectively pointless?
I contacted LG support about this and they told me it does 3:2 pulldown, so how come it says 3/2:2 pulldown on their site? I would really appreciate it if a moderator could perhaps put this to LG directly and see what they say. Perhaps there is a setting I need to change? Thanks in advance!
P.S - I am about to return this set if I cannot get rid of the judder, which I don't want to have to do. It really does look stunning.
Και η απάντηση της LG... Είναι δυνατόν;;; Κάνει 3:2 pulldown και στα 24;;;
This TV can accept a 24fps signal as an input but it will not display video at this rate. The TV cannot recover or display the original 24p content. No current LG product process a signal at the original 24p (24 progressive frames a second). This is probably due to the nature of the final picture. If processed at 24p then it would create a cinematic effect, a slight flickering that you get when projecting film like at the cinema. This is OK if watching a movie but would look odd if it was a news broadcast or content of a similar nature.
Unfortunately, at the moment, there is no way to overcome the “motion judder” that you get from the refresh rate not being perfectly divisible by 24. You end up with the choice of either adding or subtracting frames to meet the refresh rate as you cannot display part of a frame. These added or subtracted frames cause this ¨judder¨ effect. LG is in the process of making a product that will process the 24p at a 72Hz refresh rate. This will eliminate this problem but as yet there is no TV of any brand that we know about on the market that can do this
