Official LG XXLM7600 Owners Thread... - Page 65

Hi there, can anyone help me with this?... (I have also posted it in the AVR forum)

I am having problems managing to get my Amp to play sound from the TV via ARC.

I am using a Denon AVR-591 Amp and an LG LM7600 TV.

• Both units support ARC.
• The units are connected by an HDMI 1.4 ARC cable.
• The cable is plugged into the correct slots labelled as ARC... on TV: HDMI IN 1 (ARC); on AMP: Output Monitor (ARC)
• I have a Foxtel (Satellite) signal going into the Amp. When I select input: HDMI1 on the TV, and set the Amp to play Foxtel, the picture and sound both work. But when I play anything on the TV (eg- a movie via the TV’s USB input), I get no sound.

TV (LG LM7600) settings details are as follows:

• TV Input set to USB. USB flash drive plugged in. If I select “TV speakers” on input screen, the sound works fine through the TV.
• If I then select Simplink = ON and Sound = “External speakers”, I do not get any sound through the Amp speakers.
• The TV gives me a message box saying “if you cannot hear sound, check the speaker volume or optical cable. If home theatre power is turned off, it may take a long time.”
• Simplink = ON
• ARC mode = ON
• Digital sound out = Auto (not sure what PCM means – the only other choice)

Amplifier (Denon AVR-591) settings are as follows:

• Input = TV
• Input mode= -ARC
• Decode mode= Auto
• Input assign... TV shows as “-“. When I toggle down to TV, the “[ENT]:Select” option disappears. This might the biggest clue to my problem
• HDMI audio out= AMP
• HDMI control= ON
• Other info from 2-3 HDMI signal info: [Rep=1080; Colourspace=4:4:4; pixel depth=8bits; Interface=HDMI 3D
• When TV input is selected, the AMP displays "VIDEO ONLY TV"

The one thing I have not tried is buying an optical cable and using a different source. But I really don’t think I should have to find “workarounds” of something as ubiquitous as HDMI ARC in order to play TV sound through my amp, when I’ve paid thousands of dollars to do so. This stuff should be easier, seriously.

Anyhow - this has driven me to the edge of insanity. Please. Save me from my technology.

ARC only works when the TV input is set to HDMI1.

Of the 3 devices I have to play Netflix on my LM64000--PS3, Panny BDT220 br player, and the set itself the pq is best from the PS3.
Your set should not automatically switch to game mode on the PS3 input. It remembers what mode and picture adjustments you're using on a per-input basis so you should be able to change the pic mode and settings for the PS3 input manually then the set should use those on that input from then on. If you have the PS3's video output set to something other than tv standard it might also be the cause.

Darn, I knew it wasn't just my eyes. The PS3 does *look* better. That'll be a wrench in my plans trying to get rid of it. What's the point of a high end television if the source is going to be lousy. Have you tried any of the Roku boxes or the like? PQ similar to the PS3?

I'm not sure what I did for settings on the PS3, but whenever I hit that input, I see "1080p 60hz" automatically on the top right hand corner. I haven't figure out a way to change this to anything else. The PS3's video output is set to HDMI with no changes to the default settings.

I run serviio on my laptop and stream media to the tv using the "smartshare" menu. The tv can handle a lot of formats that the ps3 can't, and it does it pretty well.

Interesting, never heard of that program. How's 1080p streaming?

What about Windows HomeGroups? Can the TV recognize those?

Thanks Tampa. That makes sense.

Hey all,

Just mounted my 47LM7600 and started testing it. I usually get 33-35ms with Standard,Cinema and Vivid picture modes and 0ms with Gaming without renaming the HDMI inputs to PC. I noticed my set has virtually no clouding or flashlighting which is very nice. The Smart apps aren't so great but I didn't buy this for the Smart TV as my PC is hooked up to it. The 2D PQ and 3D PQ is phenomenal. I have been using nVidia's active shutter technology (3D Vision 2) glasses with an Asus VG236HE 120Hz monitor and I used to end up with headache after a while. Nothing like that over here.

Now for the interesting stuff. I managed to play games in 1080p @ 60hz bypassing the nvidia 3DTV play limitation of 1080p@24Hz or 720p@60Hz frame packed. You need to use the Zalman EDID to activate nVidia's interleaved 3D Mode which allows you to play at 1920X1080@60Hz without adding much input lag at all (you need to change the picture mode to game mode to remove slight ghosting). This was really good but the only downside is that you lose sound to the TV which isn't too bad for me since I use my 7.1 surround sound headphones to play. Overall I am happy with my purchase and I would recommend this TV.

If you guys are interested in getting interleaved 3D working. Please look below:
Interleaved 3D tutorial:

This will allow you to achieve interleaved 3D - 1920x1080@60HZ as opposed to the default nVidia limitation of 3D - 1920x1080@24hz or 1280x720@60hz

To enable:
Get the Zalman unlocked EDID.inf (you can do a google search for it)
Unplug any other monitors and only leave the LG TV connected

Go to Device Manager and right click the Generic PNP Driver for the Monitor and update the driver installation->Click Browse and have disk and point to the Zalman EDID.inf
Restart your PC and make sure when its up again that the monitor the PC recognizes is a Zalman one.

In you nvidia settings you will notice that there is no separate HD 3D resolution, only 1920x1080@60hz which is exactly what we want. Make sure you set the Picture to Game mode
and experience HD3D without any ghosting or input lag
NOTE: You will lose audio


To disable:
You would do this to get the audio back and when you want to watch 3D movies usually.
Go to Device manager and uninstall the Zalman driver, reboot.
Check for the Generic PNP Driver, thats it

There are a couple of instances where it has to buffer, but it is generally very capable.I would highly recommend it. There are also plugins available that let you view online resources, such as hulu.

Software update 04.22.00

I don't see anything in the menu's that have changed. Maybe SD looks better and maybe a new Premium app?

The 55LM7600's that I've seen in stores looked really dim even without the glasses. Is this an out-of-the-box setting? It was set to "Vivid", and I've heard of people running to turn off the ambient light sensor to have it bright all the time.

Did you make sure your HDMI cable fully supports HDMI 1.4? That was my problem, I bought a cheap HDMI cable from Newegg that worked great ... except that it didn't fully support the HDMI 1.4 standard (which includes CEC/ARC) ... it was driving me crazy, too, until I swapped HDMI cables and it started working perfectly. So I would try a newer/better HDMI cable (one that specifically mentions HDMI 1.4) and see if that helps.

the info display that says 1080p 60hz is telling you the resolution and refresh rate of the incoming signal, not what the tv is converting that signal to--this is how all tv info displays work, btw. The tv's settings are saved on a per-input basis, so you may have different settings on the PS3 input than on others.

Has anyone successfully used the DIRECTV 3D with their 55LM7600?

Yup i tried it on my dtv the espn 3d. And it looks awesome. My set was pro calibrated though.

The ECO mode is responsible for doing this. It makes the TV go dim to save energy. You can turn it off or use a higher energy setting and the brightness comes right back

???? Of course you turn off something that is meant to dim the picture if you think it is too dim... Maybe I don't understand what you are asking? There is more than one setting that dims the picture, the sensor is only one.

This was answered by Havoc, but to clear it up for you: Yes, there is more than one setting that dims the picture--->but I said it was in "Vivid". There, they limit the controls you have, and in fact the BestBuy grunt couldn't get the brightness up once on vivid--->"Brightness" was a greyed out thing---and other settings seemed maxed out. I found it alarming....Vivid is usually what you'll find in big box stores with the utmost "blast over your background lights and make the picture unGodly bright". In fact I've heard it speculated that that's pretty much *all* it's for, albeit glibly.

To make a long question very short: Some TV's are natively darker than others. The low end Panas I saw seemed muted and nearly all Samsungs made me blind as a bat. I was worried that the darkness might be something immutably endemic to the 55LM7600. Which is what the BB guy said. This needed clarification.

Hmm that must have been an old firmware. The newest firmware has brightness tweakable in Vivid mode.

I don't know what was up with the demo you saw at BB but we have a 7600 at the Sears where I work and it's every bit as bright as the brightest Samsungs. I own a 47LM6400 and it's also capable of burning out one's retinas. Inadequate light output is not a problem with these sets.

Btw, the "brightness" control doesn't have much if any effect on light output--it's more accurately called "black level" and adjusts how dark the dark parts of the picture are--turning it up too far just washes out the blacks. The backlight control in combination with the Contrast contro (properly called "white level") are what affect light output. My guess is that the set at BB may have been in "store" mode which locked out some adjustments to keep passersby from messing up the pq too much.

Hi guys...... I am posting this hear in the LM7600 forum, although my tv is a LM9600. This could effect you guys as well.


I just updated the firmware to 04.20.18.. After that i was toggling the "Led Local Dimming" picture setting my adjustment immediately went from having;

4-Options of; "Off", "Low", "Med", "High"

-To just having-

3-Options of; "Low", "Med", "High"

It would appear that LG or an update quirk took away the adjustment option of "Off"! I know for sure I had "Off" before this update, and it's actually still showing in the built in owners manual. Can someone else please confirm that the recent update has removed "Off" from the Led Local Dimming Adjustment.

If no one reports this I will try a reset as the LG rep suggested. Thanks.

FYI.. I contacted LG. They haven't heard of this and informed me the firmware addressed the following; "SDP 3.0 LG smart world- Adverstise click to web connection- Update social center function- Update search function- Email ID login- Remote service- Game world service".

updated mine about an hour ago mine are all still there

Ok, so your Led Local Dimming option still has "Off" as an option, even after toggling through Low, Med, High, after High you still have "Off" as an option. I just did a full factory reset and still no return of "Off". I'm not concerned with having it "Off" but maybe the board that allows for that is not working right. I'll have to call LG tomorrow.

I saved the prior firmware but LG website states you can't load older firmware.
Edited by badabing - 11/26/12 at 8:00pm

yes just tried it again off is still there.if you have a regular lg remote you can reverse the software back.

Hi, Yes, I also have a regular remote. It works fine. Please tell me the steps, I have the older firmware on USB but once I plug it into the usb it does not start an update, but I can navigate to the folder.

This is great news, thanks! At sears, are you talking about the 55" or 47"?

Add to that, there are other controls as I pointed out they could have had on, such as Clear plus, high local dimming, sensor, etc..... You should always ask to play with the TV in regular mode before deciding a picture is not good, too dim, etc... Even in the original software in Vivid brightness was always available so I have to guess it was in Store mode.

I do not believe that to be true. If you know how to do that please post. To my knowledge LG says you can not go back to an older software. (Perhaps a tech can)

I have not lost the OFF either.

55" 7600, 55"6700, 47"6700, 55"6200 all on display and all have plenty of light output. We love the 6700 and 7600 demos as they're the only 3D demo setups in the store that actually work--all the active ones have broken glasses or glitchy mfg. provided demo servers. Our dept is lit up like an autombile or appliance showroom btw.
