but don't take my word for it:

"The differences in motion blur between the 8 LCD HDTVs was not large. There were only minor differences between all of units. The reason is that the visible blur was considerably longer than the 60 Hz video frame rate, so it didn’t matter whether the screen refresh was 60 Hz or 120 Hz, or whether the LED backlights were strobed off during the frame updating. Similarly, varying the electronic processing enhancements that some models offer, which are supposed to reduce motion blur, only served to introduce objectionable contours, edges and other artifacts onto moving objects without reducing the overall motion blur. In addition, there was no notable difference in motion blur between the top-of-the-line models (which all had 120 Hz refresh or LED strobing) and the mid-line models (which all had standard 60 Hz refresh), and which cost less than half of the high-end models.

...The conclusions from everyone that participated in the Shoot-Out were consistent across the board and will likely surprise most consumers: there was essentially no visually detectable motion blur on any of the LCD HDTVs in all of the extensive live video content that we assembled. When people thought they saw motion blur, with only a handful of minor exceptions, the blur was either in the source video or a temporary visual illusion that disappeared when the segments in question were reviewed. Unlike the moving test patterns and moving photographs, the eye is unable to detect the blur in live video because the images are much more dynamic and complex, and undoubtedly because of the way the brain processes and extracts essential information from visual images. The results were identical for all of the LCD HDTVs, regardless of whether they had 60 or 120 Hz refresh rates, strobed LED backlighting, or advanced motion enhancement processing."

I don't think you're right on this. The AVSForum has a long and most excellent technical explanation about film speed and screen refresh rates, which, as I understand it, boils down to: For source origination from film, if all the digitzing (to disc) is technically correct, optimal interpolation is achieved when the refresh rate is equally divisible by 24 - the number of frames per second at which motion picture film cameras operate.

Of course that means the HDTV manufacturer has to get it right within the curcuitboard, too.

But I read the article and walked away thinking that if all I'm going to do is playback BD and DVD, 120hz is probably directionally superior. For other input sources, as you said, there isn't a human-detectable difference.

However, I have had - and just yesterday saw it on in-store demo models - a Samsung with 120hz (and their Clear Motion Rate at 240hz) that stuttered images across the screen like they were shot under a strobe light. The manufacturer HAS to get it right, or any theoretical advantage goes out the window.

can some 1 help me?

the screen is not detecting the DVI-HDMI signal correctly. in justscan mode ... the PC image is awis smaller than orginal, the TV is like re-interpolating the incoming stream

i used to be able to do it when i first set it up. i dunno wad im missing here ...

Are you saying that there is a black border around the image? I had that problem the other day, and it was driving me insane. It turned out that there was an "Underscan" option turned on in the ATI drivers for some insane reason.

Hi!

So today i recieved my 42" ld450. That´s what I expected anyway but instead they sent me a ld465 (with "W" panel).

Does anyone know the differences between the 450 and the 465? I tried to google it but I couldn´t find much about the 465 though the specs seems similar to the 450.

thanks in advance

Is there any difference in image quality between this series and LD650? (I dont care about the 200Hz function.)

Edit: between the S-IPS panels of these tv:s that is..

The specs are similar but it appears that the 465 only supports 1080p and none of the other DTV resolutions and the audio is questionable (at least the spec page I saw). I thought this was more of a monitor-like tv for the European market. A "W" in the product code for last year's models indicated the S-IPS panels (at least in the US market). This year's models have a "Y" in the fourth position of the product code indicating the S-IPS panel. Too little info on the 465 to say for sure. Seems to me to be a stripped-down 450. If you ordered the 450 why did you get a 465?

Thanks for taking your time!

Well, I guess they just messed up and sent me the wrong item.
Though this one had it´s mediaplayer unlocked which was nice.
I can easily get them to pick this up and send me a new 450 instead. do you think it´s worth it?

best,

best,

all the dtv res seems to be there. They same goes for audio. Somehow I get the feeling that this is exactly the same tv but with the media player unlocked but I can´t say for sure. There are so much info on the internet for the 450 but almost nothing for this model.

You ordered the 450 and with that set, you know what you're getting. The 465, not so much. Your call, but I'd stick with what I ordered because I'm assuming that was the set you did your research on.

yes, I have the same thoughts about it. Then again, I´m afraid that if I send it back and get a 450 without ips panel and also need to hack the usb. So if it´s basically the same monitor, I would´t need to go through all that boring stuff with re-packing etc.

I must say that his screen is fantastic. I use it mainly for gaming but also movies in all kind of formats. I have no light bleeding what I can see. fantastic viewing angle. Blacks feels good even though a lot of people have a different opinion.

I can´t feel any input lag, which was the very reason for ordering the 450 in the first place.

So I´m basically very happy with the screen. I guess could stick with it.

thanks

Is anyone else having problems with their LG 37LD450 when HDMI is used connected to a computer? I just did a fresh install of Windows 7 and after the logo it just goes blank and get a no display screen. It's definitely something with the TV because I tried using the VGA input and it works fine. I've also tried the HDMI port on my Samsung and Dynex, both of them works fine when connected to my computer.
post #1452 of 1547
Does anyone know if you can get rid of the TV selection in the input menu? I only use my TV for computer and games so it'll make switching between them simpler.

I don't think you can delete any of them. If you don't have a cable connected to the OTA/Cable input (if that's what you're asking) it should be grayed out and you can just use the PC input but I don't think that will make it default to whichever input is "active".
post #1454 of 1547
TV input is never grayed out. Even with nothing connected. You can't delete it.

All of the other inputs on my 520 are grayed out if there is nothing connected to them. I never disconnected my tv antenna to check the OTA/Cable input. I just assumed it would be the same, grayed out but unable to delete it.

I still have this. It's still awesome. Just make sure you win that panel lottery.

Anybody try the optical out? my source is HDMI and dolby 5.1 through the HDMI cable but the TV's optical out gives me Dolby digital 2.0 and my reciever can only activate ProLogic mode, not Dolby Digital 5.1. I have 42LD450. Is this normal for this model?

Thanks!

It's a limitation of the TV. It will not pass 5.1

Yes. That is how I listen to OTA tv. Thru my AVR, it sounds really nice. And yes, it is Dolby 5.1 (at least on my 47LD520). Optical out will pass 5.1 but that's all. However, it depends on your source and what you play it thru.

What I should have said is that it will not pass 5.1 from a HDMI source.

To be clear, my dvd player upconvert Pioneer DV420-V with HDMI to tv, then from optical out TV to AVR, only Dolby Digital 2.0. Correct?

Thanks!

Correct
post #1463 of 1547
Thanks doctorwizz. I followed your advice about HDMI and tried a rabbit ear antenna through the RF input. It passed Dolby digital 5.1 through the optical port.

I'm very annoyed anymore by the "new input detected screen" Everytime my pc goes to sleep mode it comes ruins whatever game I'm playing. Wish it could be turned off.
post #1465 of 1547
My 42LD450 never ceases to amaze me. Got a new HD cable box which needs an occasional reset and I get " TV does not upport HDCP, please use component cables". I takes me 1/2 hour by unplugging, plugging to finally get it to work. Anybody have a clue. I read posts that were dated 2006 with this problem and this tv is a 2010 model. My box is Cisco 4642HD.

Thanks!

How does this display stack up against LG's 2009 1080p HL30 series?
post #1467 of 1547
hello everyone, great thread! Does anyone have any calibrated settings for gaming on this set? Ive got an ips panel and am using a ps3 through hdmi. I find the game preset looks a little washed out and off colour (bluish). Thanks

If you mean the LH30 series, I can think of a couple of things: The LH30 has 3 HDMI inputs (2 rear, 1 side) whereas the LD450 has only 2 (1 rear, 1 side). The other is that the LH30 has a 50,000:1 contrast ratio, whereas the LD450 has a 100,000:1 contrast ratio. The LD450 also has a 4ms response time on the panel, which may be better than the LH30 series.

I have 2 LD450's (32 and 37 inch), and the picture is outstanding! I also have an LH20 and an LH40: The LD450's are closer in picture quality to the LH40 than the LH20 in contrast and color.

thanks for the info.
But what i'm really wondering about though is input lag for gaming....I'm going to hit up BestBuy tomorrow and i plan on picking up the LG 42" LK450, but if the lag is worse than the LH30's(which offers an incredibly low amount of lag) I'm not buying...I'd rather track down a 42" LH30 or LD450 on craigs list.

We could assume that the LK450, which succeeded the LD450 for 2011, is at least as capable, but you know what they say about assuming....
