Official LG XXLD450 Thread - Page 8

That is definitely odd. Myself and Colmino have done extensive HDMI 1080p and 4:4:4 tests on the S-IPS LD450 and it passes just fine (result is here). Granted, neither of us have calibration devices to give us quantitative measurements, but we've been very happy with PC text quality and color reproduction. And this is based on comparing several other sets.

Are you still using a PC-labeled HDMI input? If so, get rid of the PC label and set the Edge Enhancer to Off. Then set your H and V Sharpness to around 35 and 55, respectively. That should give you a decent starting point, then fine tune the contrast/brightness/sharpness until your desired result.

I've tried just about everything... i wonder if its my nvidia graphics card that is the culprit. Both you and Colmino have ATI right? Yeah i got rid of the label however that color chart i use shows the red and magenta grey text in the middle to be extremly blurry. The only time i get perfect color is if i use a vga cable. My friend got the same tv for his computer and we basicly have the same computer set up and he is having the same color issue.

Can you do me a favor and display this picture but not full screen and take a picture for me? I'll post a picture of what my tv looks like with that picture

well i decided im gonna go through with the calibration tool by using this guide : http://www.avsforum.com/avs-vb/showthread.php?t=1029594

as i have no idea where to start. It's bothering me so much that my 22" acer lcd sittin to my right looks 1000 x better than the lg on hdmi but if i hook up a vga it looks just like the 22"

i know i must seem like a nuscense on this board but i been at this for days and many many hours .. i just want what everyone claims to get with this tv.

i was familiar with how my old Sony KDL 32L4000 displayed colors and when I moved to LG 37LH30 and 42ld450 i was like where is the red tone? I thought the colours looked cartoony when increasing saturation

I notice Samsung has a very blueish tone to their tvs, Sony red, LG is yellow

they all seem to have different ways of displaying colors (XD Engine, Bravia, DNie) even when calibrated at least from my point of view

Could be that?

I would agree with you if the VGA port output was silmilar however its not. I ran a HD video/ played a game and displayed many color / 4:4:4 charts and it was identicle to the westinghouse which was connected through dvi. Soon as i change the LG input from vga to hdmi the colors are totally distorted.

btw i appriciate everyone trying to help i really do

I'm having a similar experience, nuker. I was almost at my wits end as well, but a host of other issues with my PC have taken center stage. Meanwhile, the LG is ignored. That said, just before my attention was demanded elsewhere, I ran across an issue many have had and continue to have with Nvidia cards and various displays, both HDTVs and monitors alike. It has to do with how Nvidia handles EDID info with regard to native resolution and proper 1:1. It's ultimately fixed with a registry hack. I wasn't able to investigate further, but it seemed like a logical solution to pursue.

Well it's a good thing im a computer / network technician. I had an ATI radeon x1300 card laying around and i said hey why the hell not try it.

Pop it in... install the driver... go to catlyst setting... overscan to 0... set all the usual expert mode setting on the tv with out changing any colors.. and BAM PERFECTION.

I really can't believe this crap. So you're telling me that a gtx480 does not display right on the tv.... i am at a loss lol... time to contact some people who are good with nvidia drivers.

Thanks guys

Wow, are you serious?

I was gonna do the same thing, except I would've had to buy an ATI card from Future Shop, test it and return it next day with some lame excuse about compatibility or something.

So the ATI sorted you out? Huh. I had a strong suspicion it was Nvidia related, though nothing so simple as an improperly configured control panel or menu setting. There are tons of threads online regarding Nvidia and how they continue to shat the bed with EDID, HDMI and HDCP. The EDID thing specifically requires a registry hack that's often specific to the display in question. I somehow doubt there's a confirmed hack for an LG LD450, but I could be wrong.

Good luck and gawd speed. If you manage to find a fix for the Nvidia situation, I'll be waiting with bated breath ... at least until ATI releases their 6900 series. I'm turning in my team green membership badge and decoder ring.

LOL

Thanks man.. yep you were correct in your assumption... and right before i came to check this thread i tried a registry hack for the EDID by trying to extract this LGs EDID but it did not work. I will not give up... i will never give up. I will just use a VGA cable until someone finds a fix LOL. Just kidding i am going to do some research now and see if i can get this fixed.

At least i can sleep easy tonight knowing that my tv will and can do true 1:1.

If anyone has any EDID info on this tv please feel free to join in the discussion

I will report back as soon as i figure something out.

I guess that settles it. For awhile I was wondering why some people with the xxLD450 S-IPS sets were reporting really bad image quality, whereas some people (including myself) found this display to be the greatest thing ever for PC use. Nvidia is starting to lose its shine

well it only took me about 40 hours of tinkering to find this out

lol but thats my fault i will never give up till it gets fixed

For anyone that's thinking of using a DisplayPort->HDMI adapter for the xxLD450, be sure to get an active version. I tried a passive version and it didn't work at all.

I'm personally using an Accell UltraAV B087B-002B active adapter on my 3x1 Eyefinity setup and it works perfectly fine. No degradation to image quality as far as I can tell.

Love the 5760x1080p resolution

This thread may be relevant to you: http://www.avsforum.com/avs-vb/showt...1090642&page=3

I'm VERY optimistic, but I'm not gonna rest easy until I see it for myself. I may still put "Operation: Borrow an ATI" into effect. I need to know without a shadow of a doubt that a Radeon will fix me up right. I have less than a week to decide if I keep or return the LG. The clock is tickin'.

I tried VGA myself and yeah, it was better, but it introduced too many artifacts during video playback; an HDMI fix would be brilliant.

Pooh. Your setup is siiiiiiiiick.

FIXED!!!

Here is the solution for NVIDIA cards:

1. Download the latest drivers from http://www.nvidia.com

2. Run the exe however only do this to extract the files. Once files are extracted exit nvidia driver setup.

3. Navigate to NV_DISP.INF (default location of file is C:\\NVIDIA\\DisplayDriver\\xxx.xx\\Vista 64-bit\\English\\Display.Driver)

4. Open file and insert a new line of code under the values [nv_commonBase_addreg__01] and [nv_commonBase_addreg__02]

The code to insert is Note: this will only work for the 42ld450. It might work for other ld450s but i am not sure. The EDID of the monitor is the first 4 bytes of the value above. So the EDID of 42LD450 is 1E,6D,01,00. The rest of the string stays constant.

5. Once you have the line of code under both settings, save the file and uninstall your current drivers. Once you reboot, navigate to the setup.exe which is located in the nvidia folder and it will prompt you that it is not signed. installed drivers anyway. reboot and ENJOY FULL COLOR!


If you have a different monitor and are experiencing color issues; you can grab your monitors EDID by downloading Phoenix_1_3.zip

Open program and select new EDID

Next click on the registry icon to "Extract Registry EDID"

Select your monitor here. If you have multiple monitors you might have to use a tool like moninfo to get the vendor information of the monitors

Next click on Extract EDID

Now click on the Byte Viewer button. It is the icon directly to the left of the extract registry EDID icon.

The 4 byte values you need are under the first row 08 through 0B so basicly bytes 8 through 11. Take these values and go back to step 4

oh and pooh i hate you but in a good way lol. That must be amazing i wish i could afford to do that but a single gtx480 (and then another to SLI in a few months) on this monitor will be enough horsepower.

Isn't nvidia comming out with 3d surround view? I wonder how it compares to the eyefinity

Ok so I bought the 32ld450 yesterday as a pc monitor and it installed and ran perfectly with my hd4870. So before doing my eye ball calibration I decided to read a bit and I found a post about RGB 444 and YCBCr 444 and read that YCBCr 444 is better so I check and sure enough its in RGB so i switch it and it looked pretty much the same so i left it and didn't notice any thing for awhile then about an hour ago I noticed very faint, thin gray lines running from right to left all the way across the screen. I checked all my connections, powered off and reset the monitor to factory and they where still there so I remembered changing it to YCBCr I went and changed it back to RGB 444 and the lines are gone. Dos this indicate any panel or processing issues? Should I return it to be safe?. Oh and its the IPS panel

I've processed nuker's fix and it does indeed improve matters.

I can't say whether it's perfect until I run some tests, but text is definitely much sharper, especially in PC mode. I haven't had a chance to look at it this morning with a fresh pair of eyes. I spent all day yesterday rebuilding my empire with a fresh OS and a ton of general reinstall, my eyes were pretty tired by the time I got the EDID hack in place.

Nuker, what input are you running? Blank HDMI? Or did you rename it PC? I realize the majority insist that PC mode is oversharp and artificial, but to my eyes it looks better and more "crisp" with less fuzz ... but that might just be me. I don't like the fact that it eliminates the majority of the Expert menu options, though I do have an i1D2 monitor calibrator so it's not the end of the world.

I'll be recalibrating both PC mode and the unlabeled HDMI input now that the set is receiving proper EDID info.

My only beef is, I have two displays running off my GTX 285: The LG and a 24" HP. The embedded EDID info is great for the LG but I'm not sure how it's affecting the HP. It looks different, but not bad. Can't put my finger on it.

jangaboo, which ld450 set do you have? i have the 47ld450, i used PBC settings too and increased the brightness values that you mentioned above to the 50ft settings, did you notice the reds being too bright? also, did you apply your increased brightness settings to PBC 50ft or 35ft settings or both? thanks

I have mine unlabeled. Everything i posted before the fix about things looking better was just me clinging on to false hope. After the EDID fix i finally see things as they should be and i think unlabeled is best for the extra options. If you want you can put edge enhancer to low and dynamic contrast on low or medium. I haven't found the perfect settings yet myself. I might buy the calibrating tools anyway just to get the colors perfect.


This i am not sure on. If you only changed the EDID of the LG monitor i dont think the other monitor would be effected unless you grabbed it's EDID and added it to the drivers or registry also. Again, i'm not sure.

Long story short: I got my grubby mitts on an ASUS EAH5570 (borrowed, not purchased with intent to return). I've installed it along with Catalyst 10.10, I've set it to 1080p and scaling to overscan ... but so far the results are hideous. Help a Catalyst noob! It's been many long years since I last played for Team Red. I have no idea what I'm doing here and my time with this ATI card is limited. Any suggestions would be appreciated.

EDIT: Now running pure HDMI, no more adapter.

Considering buying the 32 inch model for gaming in my college dorm. How is the input lag (to which I'm quite sensitive) and picture quality on this set?

I ask this same question in 4 different forums including this one and recived them same answear in them all. The 32ld450 is "THE" hdtv to get for pc . It has the lowest of all input lag of any hdtv including ones much more expensive.
Iv play BFBC constantly on a samsung px2370 I got this and after some tweaking it looks awesome and I can feel 0 input lag And I don't even need to use game mode. woot I love this thing, Make sure you get the IPS panel
More detail here http://www.avsforum.com/avs-vb/showthread.php?t=1285078

Awesome! This should translate well to console gaming. Are you happy with the colors and overall picture quality? Also is there anyway to specifically buy the IPS panel model online? I'll be buying from Amazon, I simply can't pass up the $415 price tag.

Meh. I dunno. Nuker's test pic set to fullscreen, for instance, looks much better on the Nvidia w/ EDID fix than it does on the ATI card w/ Catalyst 10.10 I'm currently running. The Magenta and Red text are almost unreadable with the ATI card. However, the Blue text is much clearer on the ATI than on the Nvidia.

I don't know of any way to ensure you get the IPS panel without seeing the item code on the box. IQ is excellent. On my pc the text is clear the color really pops without over saturating but what really shocked me is the contrast. The whites are very bright and the black's are very dark without losing detail. In a lot of tv/monitors I've notice that many details are lost such as white buttons on a white shirt and blacks like wise but on this ld450 with just a little calibrating this is not a problem. I love it and at sears and best buy its only $449. The IPS panel is worth the the extra $ and hassle of going to pick it up at a brick and mortar. GLHF

well its not MY pic persay i didn't make it lol... but yeah all the words should be clear and a dark grey. If any of it is blurry there is some post processing done by the tv. Ati had an EDID fix which i dont know how to do i just researched the nvidia one. When i had x1300 radeon in there it look just as good as the nvidia after the edid fix

Well, switching to ATI hasn't improved my experience. I suppose it could be an improper setting somewhere in Catalyst, I honestly don't know the ATI control panel well enough. I somehow doubt it, though.

I've had a strong suspicion for some time - over a year in fact - that my eyes simply do not agree with IPS technology. Hard to explain, long story. Glasses help, but the fact remains that I shouldn't even NEED glasses. Never wore them prior to owning an IPS monitor, don't need them for anything else in life.

Basically, I need to hook my rig up to something with a *VA panel, a Samsung C530 for instance. If my suspicion is correct, I should notice a massive improvement to text quality. My 22" TN monitor gives me no grief whatsoever, for instance. Perfect text. No need for glasses.

If I'm right, no amount of tweaking, hacking or calibration will help me. I may haul my tower to the local Future Shop and hijack a floor demo. Drastic? Yes. But it's also the only way to be 100% certain, and I'm through screwing around.

Try a VGA cable first from your computer to the LG and see if you still need glasses... if that worked then the EDID fix was no sucessfull if you still have problems then im not sure. The VGA shouldn't have any EDID info passed through it
