Thanks in advance.

The LG site may give you some idea as to what they update will do. 3.xx.xx to 5.00.00 is a pretty big jump. Make sure that the update is specific for your make and model (U.S vs European for example).

According to the LG website change log:

[What's new?]
Military Time is changed(24:00 -> 12:00AM/PM)

But since it's a big jump, maybe there were some fixes on the firmwares before.

I'm from the Philippines and I bought the TV locally here. I did see the model of my TV on the list.

I've given up gaming on the LK450. I have gone back to my old LD400 (it must have double the contrast ratio of the LK450 -- the picture is much more alive).

How can I access the service menu on my 42LK450? Need to enable dolby digital passthrough from HDMI to Optical output. Can I use a remote, or do I have to go through the RS232 somehow?

LG replied and says some models have an audio setting that will allow me to do this, though mine doesn't have that option, have to send a tech out here to set it for me. Is there a firmware update or hack through the RS232 that will allow me to do this?

The 37" LK450 arrived Today (germany). It has the magic "Y". I will still do the "Loop Test" later.

Are there any ppl who still got an AV-Panel but have the "Y" in the Product Code?

I sent you a private message.

EDIT: I originally posted the exact steps to enter the service menu to enable DD 5.1 and thought better of it. For one, LG is likely to change this procedure on TVs if it is widely distributed, and for two, others may damage their TV doing it if not careful. So if you want the specific prcedure, please do so via private message request.l

You can get into what is called the EZ-Adjust menu by using either a Harmony remote or several cheap universal remotes such as some RCA models from Walmart. I did it using an older Philps remote also. When you use a universal remote such as the RCA, you basically try all the LG model codes till you can come up with the 4 digit password box on the TV when pressing "Enter", "OK", or possibly Menu.

*** NOTE & WARNING :___ Entering EZ-Adjust menu can brick your TV just by scrolling down to certain entries and entering them. DO NOT attempt this if you are not careful or feel "tech savvy". Not even an LG service tech will be able to fix your TV if you brick it in this fashion, as some factory settings can not be made again outside of the factory using special setup hardware and software.


From the 2010 LD450 thread:
"" For those LD450 owners that are trying to get into the "EZ Adjust" service menu and have a Logitech Harmony remote, here's a hidden gem I found that allows you to do so http://harmonylghack.wikispaces.com/.""


Again, DO NOT enter ANY other menu entries in the EZ-Adjust or IN-Start Menus. I am not responsible for any misuse or entry into other parts of these menus.

You can easily look up the specs if you think it's the contrast ratio (which you seem to be focused on).

an older LG TV wouldn't have a better contrast ratio unless:

1. it was higher end, more expensive model

2. it had a different panel type with superior native CR (possibly related to #1)

3. your picture settings were good enough on the older model but the picture settings on the new model you're using are just plain wrong

No, look on televisioninfo.com. LG LD350 has a higher contrast ratio than LK450. It's a fact. They are both entry-level. LD350 is a year older.

Contrast ratio is the measurement of the difference in light intensity between the brightest white and the darkest black. The higher the contrast ratio, the better the color information. There are no standards that the mfgs have to follow in order to test and post results so the numbers can be very misleading (marketing ploy to a certain extent) and there are two types of contrast ratio, static (native) and dynamic. Dynamic is the number usually given because it's the larger of the two but the more important one is the static measurement. If you seriously want help, post your settings and maybe somebody can see a setting that you've missed or set wrong and your "problem" is fixed.

I tried PlasmaPZ's settings recently. I've also tried tweaking his settings. They looked good for movies, but not gaming. What am I missing?

One thing may be your game system settings. Both PS3 and Xbox have their own video setting as do many Blu- ray players. They may conflict and even worsen your TV settings. Color space settings, 0-255, 16-235, etc?

What game system are you using and list it's internal video settings. Then perhaps we can see a conflict and that could certainly effect your contrast ratio from your game system.

well, they are meant for movies (Blu-ray Disc movies specifically) but I also use them for games and am quite happy with the results... I could try suggesting some modifications to those settings to give games more 'pop'.

are you using the settings in post #2075?


For starters, you can increase backlight by about 5-10 clicks to bring peak white to about 35 to 40 fL. You can also experiment with the dynamic contrast setting to see if it gives images more 'pop' and depth. Flipping gamma preset from '2.2' to '1.9' should make things look considerably brighter as well, especially for daytime use. Perhaps also set color gamut to 'Wide', though I'm not sure if that really makes a significant difference on the LK450. Edge enhancer could also be used to sharpen the overall image and you can raise the color setting to make all colors look brighter.

If these suggestions don't really help, using another picture mode like Vivid or Standard could be a good starting point, though you'll want to use a setup disc to fine tune the basic settings in those modes and turn backlight way down.

For the PS3, use RGB Limited Range and YCbCr Super White On and make sure games are outputting 720p or 1080p (the PS3 doesn't upscale 720p games to 1080p, only native 1080p games play at 1080p, at least on my slim PS3). On the Xbox 360, set resolution to 1080p, use standard reference levels, and YCbCr709 color space.

those PS3 settings look right, assuming 720p and 1080p are checked under supported resolutions you TV has (it should be if you're using HDMI and let the PS3 auto detect the correct resolution settings)

Thanks for your thoughts! Unfortunately, I've tried mixing and messing with all of that stuff. Except, when using the different picture modes I didn't use a setup disc to fine tune the basic settings. I simply eyeballed it 'in-game.'

I really think for gaming my problem is coming down to the weak black level and resulting contrast-ratio. My older LD400 knocks the socks off of the LK450's black level. I can see the difference immediately when I game on it. I didn't think black level was going to be such a huge issue, I thought I would be able to tune this tv into a good gaming picture...

a bit odd since the S-IPS panel is the one with the poor black level, the *VA panel you have is supposed to have a better black level... if a return was still possible I would have said to get a Samsung with the S-PVA panel for the best blacks.

I'm considering getting this model or the 2012 model for my main HTPC setup which will also play a ton of PC games. I want a really fast TV with low input lag for gaming and accurate colors for movies. Also a TV that is easy to calibrate and has a lot of settings already posted on forums. Is there anything I should be aware of?

And you know, my LG LD400 is an "IPS" that has MUCH deeper blacks than my LG LK450 "VA." Motion and colors are better on the LK450 "VA."

Who would have figured?

That is indeed strange, I have the VA LD450 and while the black levels are fine, the amount of smearing of dark colours in motion is sickening.

The LD450 has a worse contrast than the LK450! And the LD450's motion has gotten terrible reviews. Look at televisioninfo.com

Turn TruMotion off and see if that helps.

I have a question regarding the 42LK450. How are the backlights on those holding up?

I got 2 other LG TVs a 32LC7D with 16K hours on it and a 32LG30 with 14K hours on it and the baclight on the 32LC7D still is as bright as can be and the 32LG30 has dimmed considerably dispite having less hours on it.

I don't think there are many LK450 owners with much more than 1,000 to 2,000 hours on them being only about a year into production. I have a 2010 42LD550 which had 2,840 hours on it when I checked and I have it on a lot in the 18 months or so I've owned it.

I have a 5 year old Mitsubishi LT-46231 and it still is very bright with back light set at 9 on a 0-60 scale if that is any help.

With 14,000 to 16,000 hours on your TVs you must have them on a lot. Store or business displays I would guess. How is that 32LC7D otherwise? Some past owners report it runs on the hot side due to a large heat sink inside and not enough cooling vents to provide good air flow? One review I read indicated an owner actually cut a hole in the back and installed a USB powered cooling fan. I did something similar on my 5 year old Mitsubishi after the DM board died after 18 months. There was even a place for a fan inside the Mits which apparently they eliminated sometime during early production. So, I mounted a 3" fan on the back of the TV with an air filter.

Doh! You may be right. My bad. That being the case, then motion should not be a problem at all on a 60Hz set.

Actually, low input lag is one of the strengths of IPS panel technology. *VA panels are more affected by input lag.
