If that doesn't work, just connect the line out of your computer to the "RGB/DVI Audio In" of the TV. As the name suggests that input jack on the TV is also ment to be used to provide audio when using a DVI connection without audio. You might need to use a specific HDMI input jack on the TV, label it as "PC" and/or something else to get that to work that input instead of the VGA (RGB-PC) input. The manual isn't terribly clear.

Thanks, I think all this is above my head. I'm just gonna use HDMI to HDMI, rename the HDMI to PC, and continue enjoying the TV blissfully ignorant of what 4:4:4 looks.

Ok i used a magnifying glass and from what i can tell it seems like its an s-ips panel. The pixels are certainly not straight but with the specific magnifying glass i can not tell if they are angled or they just have a curvature.

Although i don't seem to find another pixel structure that is curved i think the pixels in va panels are straight, right ?

any ways

My tv has a serial BEUYJLP and it is said to be manufactured in 2012 march

If your pixel pattern looks like what Plasma posted then you do in fact have an S-IPS panel. Please post your entire product code if you haven't done so already.

I'm looking for recommendations on a sound bar for a 37LK450, priced up to $350 or so. I've searched this thread but there isn't much here on that subject. I've spent some time in the soundbar thread but i haven't run across any messages that refer to the LK450 line. Thanks!

Does the LK450 series support Audio Return Channel on its HDMI ports? On the one hand I have read that all current TVs support ARC, on the other hand I have read that if an HDMI port supports ARC the port will be labeled with 'ARC' to indicate so. None of the HDMI ports on my 37LK450 are labeled with ARC. Thanks!

Any active soundbar with an optical SPDIF input should work with your 37LK450.

The LK450 series of TVs do not support HDMI ARC (Audio Return Channel). You have to use the optical audio output.

If the naming nomunclature is the same as it is in Greece, then in theory you should have an IPS panel. In the US the product code "CUSY means it is an IPS panel. You have a "DEUY product code. This is just pure speculation though. The only real way to verify you have an IPS panel is with the loupe/marco lens/magnifying glass or trusting the panel information at Panelook.

As far as your panel ID goes, I couldn't dig anything upon Google or Panelook about it. I think you left a character out of the

I have a hunch if you double check it, you will see something closer to "LC320WUN".

You are absolutely right i did check again and the code is indeed LC320WUN

I also checked the pattern with a magnifying glass and is seems to be an ips panel.

I also found the panel on panelook and all of its derivations are s-ips which means that my eyes are still working ok

I don't believe so. Not all newer tv's support ARC and yes, the output should be labeled HDMI/ARC or at least it's designated in the user manual. My LD520 doesn't support ARC but my AVR does (and it's port is labeled as such). ARC support seems to be hit and miss.

Interesting. LK series is the 2011 designation but you said your tv was assembled in 2012. Wonder if LG is finishing up the production runs of the 2011 series into 2012 or haven't made any changes for that line in 2012 and is continuing with the series designation. The loupe test is really the only definitive way to determine panel type as you've seen. Panelook is a good source but the codes aren't always listed there.

As i said the tv was bought from Greece. I checked two stores before purchasing my set and both stores had many in stock and all of them had the same product code as mine

Excellent! As you've confirmed with the loupe test you're good to go. Enjoy your set.

IIRC, there are a few people in the US that managed to get "2012" LK450s as well. Pretty sure it was just a production run spillover from the CS560 either not having enough units made or being held with a "street date". There's no telling how they are naming things in outer countries though at this point.

Yeah, that seems to be true. However, that's good for those who have last year's model "built" this year

Not sure how any of you can stand the off-axis contrast issues on the IPS panels, personally that lack of contrast drove me absolutely nuts. I think I found a winner in the 2012 samsung EH6000 series (full array LED backlit). Black levels are so much better than the 55LK520 LG I returned last weekend, and the style/design is a clear winner too. I encourage anyone looking for a new set to strongly consider this mid-level entry from samsung in the 2012 EH series

Not too sure what your off-axis contrast issues are but I guess it depends on your seating arrangement. My LD520 has a confirmed S-IPS panel and we can sit at least 6' either side of dead center and there is no loss of contrast or color wash-out. The blacks could be a little better on my set but it is calibrated and I do use a bias light so that mitigates the black "issue" somewhat. However, my LD520 is not a backlit LED so you can't really compare the two. Samsung makes good sets but I'm not familiar with the EH6000. Does it have the depth of picture settings/cal controls that the LGs have?

EH6000 is Edge-lit, not full-array(Samsung does not produce full-array TVs anymore).

So thanks, but no thanks.

Contrast shift > gamma shift+color shift+contrast shift(yes, maybe not as obvious with good black level) on non-IPS.

Actually. . . according the the latest info. . yes it is full array "Direct Lit". Which means it uses LEDs beind the LCD panel but Samsung does not say how many .. . supposedly a reduced number of LEDs but still provides very uniform lighting and don't know about local dimming. It must use fewer and lower power LEDs tho, because the peak light output is adequate with high contrast, but not equal to some other competitive TVs.

I was surprised also. There is much incorrect info on the net these days. It appears Samsung may have a decent mid priced winner with the EH6000 line:


http://www.televisioninfo.com/conten...DTV-Review.htm


I have been reading up on the 46EH6000 all morning now. It is a basic TV with minimal inputs and no net apps or 3D (good to me). It says it has 2 HDMI and also an optical audio output.

Reviews are good with some motion artifacting if the motion hadling is used. Sounds like a decent 120HZ TV. . . it isn;t 240HZ.

I only have seen this issue in the vertical axis on the S-IPS panel version of one 37LK450 and two 42LK450s. View the TV at eye-level and the issue disappears.

Yes. . I saw the Twice.com article and several others, but since this is an LG thread thought better of already adding to more off topic clutter.

I also went to BB and saw and spent time with the 40" and 46". Garnered a remote and got into the menu. It has a 2 point with RGB high and low cuts. Lighting looks really quite good for an LED and at well under !K for a 46" I would try one if I needed it.

One of the reviews says the 40EH5000 performs better than the EH6000 which is interesting. Samsung has finally done what I was hoping for. . . produce a full array (albeit reduce LED count) back lit LCD for a mid price point. I expect this will become common place in 2 - 3 years.

The lk520 ips I had the screen would change image a bit off center(nothing to bad, more noticeable in dark room).It changed side to side and up and down.Couldn't tell if it changed more up/down or side to side.

My 2 cents

If it does indeed happen in the next 2-3 years, I'll be upgrading sooner rather than later to LED-LCD's. There are a couple of TVs in the house that are starting to show their age and it will make sense to upgrade those to something smart and modern.

My 2 cents

all of the ips panel LGs I've seen show no color or gamma shifts in the horizontal viewing axis... the image only gets a little dimmer overall at extreme angles, which is barely noticeable unless you move left and right while watching the picture.
