Official LG XXLD450 Thread - Page 40

You're very welcome. I'm unable to answer the question you just asked about using extenders, but hopefully someone else here can answer it.

dzasta,

Thank you! The aspect ratio settings were the one place I didn't look :-)

Best,

Brian

I meant to point this out to you in my last post, but you can also change the aspect ratio more directly by hitting the "ratio" button on the remote multiple times until it cycles to the aspect ratio you want. The "ratio" button is directly between the volume +/- and channel +/- buttons.

From a pure electrical standpoint, you would be introducing delay as your adding circuitry in series from point A to B as supposed to a "straight through" connection (ie HDMI cable from PS3 directly to TV). If the extenders are a simple straight through connection there would be minimal delay if any. But if your adding in a HDMI hub or other hardware, you are definitely introducing propagation delay which should be minimal from a input delay standpoint as we're talking micro seconds. But a delay is a delay.

Good point, I missed that! I've only owned my TV for... 15hrs so still learning the ropes!

@ dzasta: Interesting information you provided on the use of extension cables. Even though I wasn't the one asking the question, your answer is appreciated by me.


Hopefully you'll be happy with your purchase. Most people who own the LD450 who have posted here seem very happy with it. A few small complaints here and there, but yeah, most seem happy.

As for using the "ratio" button on the remote, the reason I suggested hitting that button multiple times until it cycles to the ratio you want rather than using the quick menu (I do this for the "input" button as well) is that I found the remote's menu navigation pad to be exceedingly cheap, and I figure the less use it gets, the better. All of the regular buttons seem perfectly fine, but that menu navigation pad is suspect in my opinion. In fact, on my original remote, the menu navigation pad stopped working properly after just a couple of months, and I had to get LG to ship me a new replacement remote. Currently, I've got that brand new remote stashed away and am using a simple programmable remote so I don't have to worry about wearing out the official LG one.

So are you saying that with the universal remote you can access all of the features on the TV just as if you were using the LG remote? This would be awesome if it worked on my fios remote. I've programmed my fios remote to turn on/off and change volume but i dont think it can do anything else after that. Apparently they updated the fios remotes to a simpler version where you can't toggle btw modes. ie press 'tv' then use the remote to change tv settings; press "aux" to change receiver settings, etc. hmm maybe if i can source one of the "older" fio remotes... a harmony would be nice but seems overkill for a simple bedroom tv setup.

My particular universal remote is this one here: link to RCA CRCRP05B remote on FutureShop's site

I only use it for the TV, so I can't speak for its functionality with other devices. It does have several LG codes listed in the instruction sheet that comes with it, and I believe the first code listed will have most things mapped out perfectly (menu navigation pad, volume, channel select, etc.)

The more specific features don't work by default though, though I do have mine set up so all features are accessible. See, it's a "learning remote", so as long as you've got the LG original, all you need to do is follow the instructions on how to make it "learn" something. It learns by having you point the original remote at it (works best in lower light conditions for the learning part) on which you push the button you wish to have emulated on the universal, and the universal will copy that exact function to whatever button you want it mapped to.

Then, of course, you'll have to remember what buttons you assigned the functions to, but once you're used to the way you set it up, there shouldn't be a problem. As one example, I don't need the "on demand" button on the universal remote, so I have that button programmed to emulate the "aspect ratio" button on the LG original remote. This is why I want to make sure I keep a good, working official LG remote: so that if I ever get another learning remote, I'll be able to teach it using the LG original.

So yeah, with the way I've got my universal set up, I can access every single function that's available with the original LG remote. Not bad at all for a remote that only costs around $25 Canadian (I'm in Canada).

Good to know thanks. Can you access the service menu using this remote? If so, I'm planning on buying this remote today at a store.

Edit: Can you plug in a external HDD to the USB port to watch movies (assuming the USB hack was implemented)?

I've never tried accessing the service menu, but even if I wanted to, I doubt this remote would have that feature. You could, in theory, have someone with a service remote of some kind use their remote to "teach" the learning remote the right signal to send to the TV though.

As for the question in your edit, I don't know the answer myself... Even though I don't really plan on trying to enable movie playback with my TV, I'm kind of curious myself as to whether or not you could use a hard drive. I'm not worried about that feature myself because I actually buy legitimate copies of movies I like, so I never download any (I know... I'm an oddball that way, lol)...

[EDIT]: If you do pick up this remote, be sure to read the part in the instruction sheet about how to "unlock" the volume buttons for the TV when in TV mode. They lock it by default in case you're a person who only uses other external equipment to adjust volume levels, so that the volume buttons don't affect the TV's own volume level (but you can program it so the volume buttons will adjust the volume on your other equipment while staying in TV mode with the remote). I didn't read about that part myself at first, and was thinking that something must be wrong with the remote or with the code I put into it for LG TVs.

yes, i presume you could use a universal remote to acess the service menu. I tried using my Philips universal remote which I got it in 2007. I made the remote work for the tv and tried pressing the guide , tool buttons on the remote and viola on one of the buttons, the password came up. I put in 0413 and I could access the service menu and go to the option to change the divx from 0 to 1. Now the tv reads movies off my external Hard disk. it reads all files except mp4's. the movies play perfect.
you can try this out without fear of bricking your tv. I have enabled the THX option and the Divx option from 0 to 1. I have not meddled with anything else.
I have heard people making it work through rogers or bell univ. remotes. check it out with the same method i mentioned above before you shell out the extra bucks.

let me know if you have any doubt.

I am hoping someone can help me out here. I just got the 32LD450 from Amazon and it's an IPS panel. My main use for this thing is going to be a PC monitor. I have it hooked up to my laptop through HDMI. It doesn't pass the 4:4:4 sampling test and text is pretty fuzzy. When hooked up through VGA, it does pass the test and things are much better.

My laptop has the Intel integrated graphics (Intel HD Graphics). I tried the EDID override, even though it's only for Nvidia and ATI, with no luck. Is there anyway for me to get 4:4:4 working with HDMI? Thanks

Thanks Angry Lion and Sandyr,

Thats good to know that external hard drives work! I also did pick up the RCA remote today and by default it worked on my fios dvr cable box. I programmed the TV in but the guide button didn't access the service menu. To my surprize though, I noticed that this TV already has the movie playable enabled! I just never bothered to check. Could this be a new feature in the 2011 LK450 line? However, I would still like to get in the service menu to unlock the THX goodness, and simply explore. I will research more into programming the RCA...

You're most welcome. So was I mistaken in thinking you had an LD450 (I might have had that wrong)? Is yours one of the newer models (an LK rather than an LD)? If so, sorry for the slight confusion or inattentiveness on my part.

Glad the remote is working out for you. In case you haven't noticed yet, I don't think that, by default, the 4 coloured buttons (yellow, blue, red and green) match up to the appropriate colours on the original LG remote. I had to "teach" each of those specific buttons the right colour according to the LG remote. I don't use those buttons very often, mind you, but it's good to have things set right in case you do ever need to use them. I can't remember for sure, but I think that the remote can remember up to 60 custom buttons that you teach, all told (that's 60 buttons total, no matter which mode/device you switch the remote to).

So what you're saying is the lag will go from 1-2 to like 4-5?

I just got a 37LD450, and I'm having problems with the stand. It seems to be crooked, any help?


Edit: It swivels, I'm dumb.

glad your tv had it enabled already. It was a masssive improvement in feature for me when it started playing the movies through external HDD. Like Angry Lion I too presumed you were having the LD model.
The THX modes are 2 picture modes thats all. Although I enabled them i don't use them for now.
Enjoy your tv.

I honestly don't know how propagation delay would translate to input lag. If I were a guessing man I would say in the worst case you would observe a one frame delay. But realistically, we're probably talking fractions of a frame.


Isn't there something else I can unlock? Was it the AC3 audio codec? I can't remember where I read it but I thought there was something else. So I tried playing a 2Gb 720p divx movie and it played fine. But of course I don't own any external HDDs and my biggest thumb drive is 4Gb (3.75gb). So now I have to invest in a decent external HDD. 1080p content can easily surpass 12Gb+

For all those wanting to use an LCD TV as a PC monitor I recommend the Philips xxPFL5405.

- Uses an AS-IPS panel from LG (check my pic posted in Page 8 of the "Lcd Matrices" thread on the UK equivalent of this forum)
- It has 4:4:4 full chroma support (using the Bell-Nuit Test chart I confirmed this)
- Very low input lag (17ms on average) in PC Mode, can display pics if anyone wants.

I have read on several forums, notably this one, people saying that the LG xxLD450 is the best tv for PC use.
I disagree, that model uses an S-IPS panel which produces a much weaker contrast ratio and weaker blacks than the AS-IPS panel.
The input lag on the LD450 is the same as on the PFL5405 and the Philips has 100 Hz!
The xxLD450 can also reproduce full 4:4:4 chroma but only after installing the EDID override fix.
The Philips reproduces full 4:4:4 right out of the box!
All the advantages of the xxLD450 + a better panel + more uniform CCFL backlighting (in my case anyway, Philips have always been great with their backlighting) + 100 Hz!

PFL5405 = Superior for PC use IMO.

I think your problem lies in the fact that you are stuck with the integrated intel graphics processor. Nvidia and ATI offer high customizable graphics drivers where they offer end users tons of customizability (is this a word?). For example, with Nvidia/ATI you can adjust overscan settings and many other settings which I'm guessing your integrated graphics drivers don't let you change. I have the same problem with my laptop as A) it only has a VGA output B) it probably the exact same integrated intel graphics chip on it as yours C) the laptop is slow as hell

Thanks for the info. My only irk about this statement is what you tested was the UK model. From what I've read in the past (not sure if true or not), Philips has a much larger market presence in EU than the NA market -- and therefore has better access to the premium versions of their TVs. Whereas the NA market generally gets the dumbed-down / inferior versions; even if both markets use the same model designation.

This wouldn't be the first time where there was a clear difference in performance between UK and NA versions. Ex., UK Sony EX500 vs. NA Sony EX500.

If someone can confirm whether the North American version of this model is true, I would be very interested.

Hi pooh, I do indeed have the European model (I live in Belgium). I was unaware that the EU / NA models perform differently. I have a friend who has the European model of the 42LD450. I could perform some tests if you would like (for comparison's sake)?

Yes, I believe thre was this talk about the Ac3 codec. I can't seem to find any tips to unlock that one in this thread. I tried going into every option to recheck but can't find it. maybe it's under a different feature name . If someone can point it out that would be great.
thanks

Nah, no need to test the EU version of the LD450. I frequent the LD450 thread over on AVforum and the performance between the EU and NA versions appear to be pretty much the same.

Its only a conjecture on my part about the potential difference between the EU and NA Philips 5000 series. If your findings hold true for the NA version, that would be awesome. Since finding a low lag + 4:4:4 LCD TV is practically impossible.


I remember seeing something AC3 related right on the main screen of the EZ-Adjust service menu. It was something like "AC3 EDID D/L". I'll double check when I go home tonight.

Thanks for the input. 4:4:4 sampling works flawlessly over VGA, so I used it most of the day yesterday. I then decided to hook it up to my desktop (NVIDIA GPU) through an HDMI-DVI cable, and voila, I have got a perfect image and the display passes the sampling test. I was still a little disappointed by how the text was being displayed so I used the settings posted in the FAQS, and now it looks great with razor sharp text. Getting the sharpness right made a big difference.

My laptop is fairly decent sans the GPU (i5, Intel SSD, 8 gig, don't need a strong GPU) and I use it to run computer code for nuclear reactor safety analysis. I get these huge text files along with modifying computer code, hence it is imperative that text be sharp. At the moment I have my desktop hooked up to the LG and the laptop to the Dell 2405.

I do miss the 1920x1200 resolution and I'm having some trouble getting used to the massive pixel pitch (relatively speaking).

I apologize in advance if this has been asked and answered before in this thread.

Yesterday I purchased a 32LD450 with a IPS panel. I read here that the input lag for this exact brand/model was 16-32 ms. I mostly play Rock Band and when I ran the auto-calibration tool with my wireless guitar on Rock Band 3 the numbers it gave me were:

Audio - 75 ms
Video - 59 ms

The numbers (I ran the test multiple times and received the same number with maybe a 1 or 2 ms difference each time) I received for Video delay with the calibration tool are much higher than what I saw in this thread from the tests "thepoohcontinuum" ran. Do the numbers I received from the auto calibration test have anything to do with the TV's overall input lag for other games such as Street Fighter?

*Edit I ran the Auto Calibration on The Beatles Rock Band and ended up with, Audio: 68ms Video: 27ms (again ran multiple times), I'm gonna go ahead and guess that the Rock Band 3 engine is wonky and introduces additional lag?

@ Vildiil: Hi. Have you tried running the TV in "game mode"? I believe game mode will keep things like picture processing to a minimum, which helps reduce lag. To set the TV to game mode, go into your picture options, and for "picture mode", set it to game mode.

You can also set the TV's settings as a whole to "game mode" by using the "AV Mode" button on the remote, but that's a less desirable method since doing that will also monkey around with your audio settings, and won't let you adjust them (while in that mode). So yeah, just go into your picture options and set picture mode to game mode in there, since in there it only affects the picture options, and not the audio.

Yes, I made sure I was running in game mode and I also used PC mode. I selected them through input like in this picture, made sure all user-configurable processing effects were turned off. I am running the xbox HDMI > HDMI.

I have this extremely high pitched whine coming from the set. It is not loud, but can be perceived very easily. It is really starting to get on my nerves. I have tried changing the outlet the set is plugged into, played with the backlight settings, but no luck. It is definitely coming from the back of the tv. It is starting to fatigue me, so I may be returning mine back to Amazon.

You are better off returning your set if you can. In 2008, I bought a 42 inch LBX model and suffered through this noise even after exchanging with BB once. My hubby would not do the exchange again. He was happy with the pic and the noise didnot bother him. On the other hand my kids and I could hear the noise. I called LG and they sent a tech who took the tv to their store to check and got it back saying nothing was wrong but we still changed the motherboard.

The supposedly fixed LG started now to give a high pitch whine even when the tv was off. I had to call LG again and they sent me another tech over to check the problem. this one took the set to the store. kept it for 2 weeks and said the power supply was gone. Anyways I still am stuck with the noise now from the speakers when the tv speakers are on.

The worst part is that the tech's wouldn't even take the effort to listen to the sound and would straight away say that there is no sound and that I am hearing things. The hassle of going through left a bad taste of LG in my mouth.

I guess LG would not leave me because my hubby bought another 37 inchLD450 from BB to replace the crt we have. I am crossing my fingers on this one and hope it has a trouble free llong life [atleast 10yrs] like my JVC crt which ran for 14 yrs and still going strong.
