I know most people would say this is down to personal preference but i was wondering what people thought of all the picture processing you get nowadays with tv's. For example Sony tv's with 100hrz-400hrz refresh rates. Are they any good at what they are supposed to do and do most of you turn theses features off to get a truer picture when watching blu-rays at the native 24fps?

I just be interested to know peoples opinions and that off the WHF team!

I had a bit of a strange experience with my 46W5500

Initially motionflow even on 'standard' was awash with strange effects which made me sick just looking at it. Setting it to high was almost unwatchable

6 months later I decided to try again. This time standard setting was fine, and made some 'flickering' go away. So most of the time I have it switched on now. It can create a slight 'screen tear' with certain conditions, but these would go unnoticed by most people think. Some 'dark' scenes (Particularly out of focus ones) can have a strange 'black smear' effect. Switching off motionflow definitely helps with this

The one thing I now never switch on is sonys 'film mode 1' as it makes all film very unnatural. Its like motionflow on drugs. But film mode 2 needs to be on for the tv to accurately flag sceen information (Doesnt matter for games, where 'game mode' can be used)

Generally speaking its worth having for me as with standard 50Hz mode I can sometimes notice flickering (Maybe I just have eyesight susceptible to it, where most dont)

As Andrew rightfully points out though, the vast majority of 'picture processing' should be switched off (live colour, contrast enhance etc)

If this is the case, then why do the manufacturers put this stuff in the spec? Is it just so it looks like each tv does more than the last?

What would you recommend turn on or off for blurays?

I always think it's a bit like Dolby noise reduction on tape decks years back. The good decks were expected to have it, but the audiophiles woulf then not use it as while it reduced noise it also affected the actual music.

If you turn the processing off you'll see the 24 frames per second recorded for the film. Or you might turn some on to repeat the frames and reduce flicker, or maybe calculate extra frames in between to make motion smoother. There are benefits, but might make the pciture look unnatural.

If you're an abolute purist, turn it all off, or at most for for frame repeating. Otherwise just experiment and see what you think looks best.

Most processing is pure marketing. Those not in the know would want the tv with all the trimmings, as theyre unaware that the trimmings make the picture look worse

ALL the 'brand' tvs have the trimmings as so many are unaware. If the tvs were bare bone spec, they wouldnt sell

It's not just trimmings that make the picture look worse. Panasonic can't even get the basic core picture processing right this year without introducing dynamic contrast and black level anomalies!

It will insist on meddling!

2010 Panasonic plasmas have been suffering with floating blacks, where the black level is messed with during film or other material. This can raise the black level of bars on films and give an unsubtle flashing effect in dark scenes or darkly lit films.

The Z1 model was carried over into this year, and as such has current firmware revisions. It too hasnt escaped unscathed from this currently buggy software processing.

I applied the most recent 2.506 on my Z1, and it is in some ways worse than the last revision 2.503. I now get contrast spikes for no apparent reason, even in brightly lit daytime TV, and on BBC Snooker I get flashes or pulses happening randomly on the main table shot!

, all since the latest software update.

Why can't Panasonic leave contrast and black level alone in Cinema and THX modes? If THEY stop playing silly beggars with their processing, I may get a watchable picture!

Other anomalies that remain uncorrected are flashing occuring in backgrounds or in characters faces in dark scenes. Cinema, THX modes suffer, but not Normal or Dynamic (both unsuitable for critical viewing) picture modes.

I dont know that Panasonic listens much to customers after the sale.....

I dont have a pan so unsure, but can you not calibrate Normal or Dynamic modes?
