Samsung: LN52A650. Is My 120hz Working As Intended?
LN52A650. Is My 120hz Working As Intended?
by Louche1 - 10/17/08 9:39 AMI bought my 650 a couple months ago and I am still unsure of whether or not my 120hz works, but that's probably because I don't really know what it is other than what this article tells me (http://reviews.cnet.com/4520-6449_7-6792632-1.html) For one, is "Auto Motion Plus" the setting to turn 120hz on/off ? As in, if it's off, everything displayed on the TV is being displayed at 60hz? The reason I ask this question is because if I even turn whatever I'm watching onto high, and press the Info button, it still says that what I am watching is 60hz. I can definitely tell when I have the Auto Motion Plus on as everything seems "smooth". But to me even on low it actually seems too smooth, like the article says "It's worth noting that the picture on the standard setting sometimes looks unnatural, too, particularly when the anti-judder suddenly kicks in during a fast pan and stabilizes objects moving across the screen." Is that what it's still supposed to look like? Am I to be expecting everything to look unnatural? And if so, is this something I should just keep on and eventually will get used to it? Or is it just a love it or hate it thing?

Louche1,
The quick answer is this: The 120Hz panel is a 120Hz panel, and will only show images at 120hz.
The input content source is what you're seeing when you press the "Info" button on the remote. What you're seeing is your source material. Cable/Sat boxes will usually input at 60Hz, and the processing inside of the television will upconvert that to 120hz. Some people prefer to see movies in 24Hz when available, and some prefer 60Hz. Both of those formats are equally divided by 120Hz, which is one of many reasons people purchase a 120Hz panel.
Smooth motion is another. The processing at 120Hz is a benefit for LCD panels particularly. I could go into why that is if you'd like, but it can get pretty technical.
You can turn off the Auto Motion Plus processing by switching it to "off", if you like. That won't revert the panel to 60Hz, it will just turn off the processing associated with the upconversion - that processing usually improves the picture. But turning off that additional processing should help remove some of the "unnatrual" movement in picture. There are several different options, and each input has a specific setting for Auto Motion Plus. Your cable box might look great on "high" while your Blu-Ray Player looks great on "low". Adjusting each input setting should allow you to reach the picture you want for that particular source.
Hope that helps. If you have more questions, please let me know.

trim and halo effect

Mr. Samsung - for a sample image of the A750's trim turning white, just look at Amazon.com's product page for the LN52A750 .. there are a couple user submitted pictures that show this problem.
Also - I've read numerous reports of a "halo" problem with the A750. If look closely there is a clear-plastic trim that runs along the frame of the A750's screen. Apparently this clear plastic trim is very adept at catching light from the TV in a dark room, and it make it look like the TV has a glowing halo around it.
120Hz is always on

I have the same issue as Louche 1.
So when I push the "Info" button on the remote and it says it is coming in at 60hz it is actually coming in at 120hz (noting that the AMP is turned on)?
I have no idea if my TV (Samsung LN46A630) is actually processing at 120Hz. Very frustrating.
Yes, 120Hz is ALWAYS on
by Nautiduck - 1/20/09 4:24 PM In reply to: 120Hz is always on by jayofunkThe panel can ONLY work at 120Hz. It doesn't matter what level the AMP is on or if the AMP is off. 120Hz and AMP are two different things.
When you push the Info button you see the INCOMING signal. It is telling you that the source (Cable Box, DVD player, etc) is at 60Hz. The Samsung is ALWAYS at 120Hz.
AMP is just a feature that lets the TV modify some of the frames to make the picture motion seem more fluid. Some people like it, others not. So let's say you are watching TV. The TV Cable Box is sending 60Hz (frames/second). The Samsung displays 120Hz (frames /second). So with AMP off the TV just plays each frame twice (60 X 2 = 120). Turn AMP on and the TV will modify the added frame to make the motion more fluid. This is even more relevant when watching a 24 frames/second source such as Blu-ray. There the TV, with AMP off, plays each frame 5 times (24 X 5 = 120). AMP can really get to work modifying those four extra frames if you want it to. Some love it, others hate it.
Yes, 120Hz is ALWAYS on

Your explanation is the best one I have read and I have been searching for 4 days now.
Being a relative newbie to 120hz technology makes it tough but the TV is still way nicer than my 32" Sony that I had before.
So what will input at 120mhz?
by Chargerswin - 1/25/09 8:03 PM In reply to: Yes, 120Hz is ALWAYS on by Nautiduck1st post on c/net: I have a Samsung ln46a630 on its way it's replacing a faulty 42" sharp with bands. I have been looking at the calibration questions and the questions regarding the 120mhz. I understand that info will display what the incoming signal is and the panel will display 120mhz no matter what. Is there anything currently that inputs at 120mhz? Are sports from over the air digital going to make better use of this technology?
Thanks,
Joe
Blu Ray at 24
by sanjayb - 1/26/09 4:29 AM In reply to: So what will input at 120mhz? by ChargerswinThanks to the above posters on the 120mhz issues. It was great information. When I hit the info button on my Blu-Ray player it says 24mhz. When I first saw this, I was thinking I was getting worse picture quality than my cable box which shows 60mhz. Although my eyes were showing me a fabulous picture. I am assuming that even if my Blu-Ray player says 24mhz I still getting the best picture possible? Correct?
