I think the auto dim feature is a power saving option for the TV,where the picture goes from dim to bright depending on your lighting..
Anyway,i have turned my 200hz mode to "off",i just cannot stand the juddering effects,
If you have decided on this TV,please check also on the warranty,its either 2 years or 2+1..
Please be aware that malaysian sets do not play DIVX-HD,has only 3 hdmi (not 4 as per singapore sets)..you also cannot upgrade the firmware to play MKV files coz its customed to malaysia
But all the Philips have the judder effect and the auto-dim issue.
If you haven't notice, just concentrate on the Philips and you'll
see that it'll auto-dim itself to adapt the bright and dark scene.
I called Philips and told them the problem and they were happy
to give me a full money refund.
I've tested the LH50 with The Wrestler movie.
The opening titles of the movie have the text infront and the
background panning from behind. In my old Philip the text
and background judder like crazy.
But in the LH50 the judder seems minimal.
There weren't any auto-dimming issue either.
I believe there are ways to check with the LG Headquarters
whether your set is a new set or not.
So for me, this is too good to be true,
especially for a knock-out price at RM3190.
I'm waiting for a second person opinion of having the LH50 set
commenting the pros and cons before i decide of getting it.
