Hmmm, so just reset to default Expert 2 (I've got his cool settings in there but I haven't used it for any of my inputs) and then tweak away? Sounds easy enough.

Then how does sharpness settings work in an lcd tv vs. a crt tv?

Otto, I was doing some research and ran across this video on calibrating tvs on youtube and I thought of you. It'sby Revision3 and seems pretty up to date. They talk about and use THX on a Pixar dvd and show some of the DVE patterns too. I liked watching them make the adjustments and the fact that they were using an LG.

Edit: Forgot to mention that they talk about source and appletv too.

Don't do that, it only adds to the strengths that are you.

Thank you. shhhhh, I actually like DWTS but don't tell anybody

I'll have to check out that YouTube. I've got the disc to burn, a brand new Panasonic 210 so I'm good to go.

Hey! A daytime post from you, how nice

Sharpness is completely artificial with digital TVs. It should always be set to neutral, i.e. no artificial sharpness added. In the case of our LG TVs, this setting is 50 for both horizontal and vertical sharpness. Edge Enhancement is also best turned off. As with everything else, it's a personal preference. So, if you like the added sharpness, by all means, go for it.

That's pretty much it. Reset Expert 2, leave Backlight at the default 30 for the time being, turn off Edge Enhancement, and make sure the color space is still set to BT709.

Cool. I just watched the YouTube vid that sheesh posted. Very interesting. And as she pointed out, they demo it on an LG! They used the THX disc.

Yeah, nice little video. Thanks sheesh

The AVS disc works the same, but the patterns are much better.

I have some THX Certified DVDs which apparently have the calibration routines on them (never paid attention before) so I'll try that first and then burn the AVS disc, try the basics on that, and compare. I just reset my OTA Expert 2 settings back to default so I have a clean palette to paint on and play

I figured as much and will try to devote some time tomorrow.

Someone said to me that they didn't think that the majority of Americans would want a feature such as the Expert controls on the LG. I was already on youtube and decided to do a search. You tube not only indicates the number of videos uploaded but also the number of views on those videos. I think there a lot more people than R&D at other manufacturers would like to believe.

I think LG has ruined me in some aspects.

It only takes a fraction of the time to burn compared the download.

I downloaded Imgburn and made the disc in much less time.

Depending on my mood, I'll either use the Apple Disk Utility or Toast. I've already checked my current settings against my printouts so I can mess with impunity and put it all back together if I don't like it One of my girls is coming home tomorrow for a few days so I'm sure she'll give "daddy nerd" a bad time .

Hey all, I've also downloaded the AVS disc and I've explored but not yet done any tweaking. One question: What kind of lighting conditions should be used -- normal daylight conditions or night/bias lighting conditions, or does it matter?

The one you watch tv in the most. If you like your results then use the other Expert setting for the opposite conditions so you then end up with one for day and one for night. Just make sure it is day or night out when you do the calibrating and if you watch at night with a light(s) on don't turn them off.

Thanks for the link!

On the AVS HD709 disc - I think the "HDTV calibration" menu pick, top-right, these same guys do the same steps using the AVS disc. However, in your link they go into more detail and they've really stepped up their game over time. Their presentation skills are much improved.

Hey guys (and sheshe),

Last night I downloaded and burned the AVSHD 709 calibration disc using ImgBurn and started calibrating my 47LD520. I used Expert 1 with Warm, Gamma at 2.2 and all picture helpers off. I set the backlight at 30, plus/minus a few for room conditions.

After using the Basic settings to get started, I found a pattern in the Advanced settings called 'B1 - Flashing Primary Colors'. This seemed similar to the basic SMPTE-type color/tint pattern, but with color/tint bars for red, green and blue. I then used the Color Filter setting on the 520 to calibrate the color and tint for each primary color. I was able to get the green and blue settings just right, but I could not get the red tint area adjusted properly, so I just left it at 0.

Once this was done, I set all of the IRE settings to 0 for each color, from 100 down to zero, since I can't really adjust those properly by eye.

The picture seemed to be relatively close to djams/Carl's 47LD520 settings already posted.

Has anyone else tried this using the AVSHD 709 disc? Does this sound like a reasonable method to use for someone without the proper hardware/software to do a proper calibration?

I also have the Disney WoW calibration BD, but I don't remember it having the same pattern.

I can post my final settings this evening if someone would like to see them.

Ed

Hi Ed. Good to see you here. I too have the 47LD520 but haven't had a chance to do any "in-house" calibrations yet. I've been using primarily Nick's settings with some of Carl's suggestions and I'm very happy with the results. I haven't burned the AVSHD disc yet but plan to do so tonight.

The YouTube link that sheesh posted is a pretty good primer to calibrating and apparently if you have any THX Certified DVDs, then you've got a basic calibration program, which could be used as another check on the WoW or AVS disc. Please do post your cals once done, and the inputs used

LG did a fantastic job including all those options. I have never seen this many user-accessible settings on a TV. This will most likely be the main reason for me to stick with LG in the future.

@ bstarfish

I did exactly that when I first started using the AVS disc. You did everything right. There are basically two ways to start out at. One is to leave the main Color and Tint settings at their defaults and then adjust the individual colors and tints in the CMS, using either just the blue filter or all three.

The other (simpler) way is to start with adjusting the main Color and Tint settings with the blue filter and then either just leave all CMS settings at their defaults or adjust the individual colors and tints after that.

Here's the thing, though. Blue is super easy to dial in, but red and green are not, with red pretty much being impossible. I've been reading about this a lot lately, and it seems that most people recommend to only calibrate for blue.

I currently have two slightly different sets of ISF Expert 1 and 2. For ISF 1 I used the first method, adjusting for all primary and secondary colors in CMS. I was able to match blue with grey, cyan and magenta, green with yellow and cyan (but not grey), and red with magenta only. This got me a very nice picture.

For ISF 2 I used the simpler method of only adjusting Color and Tint, which means that only blue, grey, cyan and magenta match perfectly. The result is a slightly more colorful but overall brighter picture. The reason for this is that with this method, I was able to set Contrast higher due to the colors clipping later.

The most important thing about setting Contrast is to not only check the white level pattern but also the color clipping pattern. You don't want white or any of the colors to clip below the 235 mark.

Anyone's head spinning yet? I'll be back to answer questions after lunch.

Yeah mine. I just fell out of my chair trying to hold on. Why do you do this to me Just when I'm comfortable with what I have, you post something new and I gotta go and try it. And now that I have that very dangerous AVS disc in hand (well almost, I still have to burn it), Ima gettin' all twitchy again Sounds to me like you and Nick are in cahoots and just messin' with us. Now, if I could just find where my lunch landed....

Nick! You can't leave us now . You have to wait until it's a nice and sunny 85 degrees, like here in LA right now. 90-something tomorrow!

Nooooo daddyyyy don't leave me! Well, maybe that was a bit strong Dewd, I'm with Henry. It's only the low 70's here in the Bay Area but warming up to the 80's real soon. 85 is the official cutting out temp. Besides, I've got your email address.... heh heh heh.... and I'm not afraid to use it!

Hell, I was just getting used to this social networking business........ still can't spell Facebook or Twitter

Poblanos huh? I prefer an early season Red Savina (even tho my wife won't kiss me for days after that!). Yeah, it's a good thing we weren't neighbors.

Nick: ♥


I have to go to bed now. I had a poor night and day.

Yeah well messing with the sharpness all that time seems to have been detrimental. Because now when I was watching an OTA SD digital channel, lines seemed to "break up" here and there. Never before.

Thanks for the confirmation!

I just rechecked the color clipping pattern. My red is clipping quite high at 251, green at 247 and blue at 245. I had to turn the Contrast down to about 88 to keep the picture from looking over-saturated. Turning the Contrast up to 100 clips the colors at 235, but it just looks wrong. As I was typing this, I thought to adjust the magenta color. Setting it to 5 got all my red filter settings to match up. Yea!

Here are my settings for this go round:

Aspect Ratio: Just Scan
Energy Savings: Off
ISF Expert 2

Backlight: 30
Contrast: 88
Brightness: 54
H/V Sharpness: 50
Color: 50
Tint: 0

Note: I left the main Color/Tint vales at default since I am modifying the individual color values below.

Dynamic Contrast: Off
Noise Reduction: Off
DNR: Off
Black Level: Low
Real Cinema: Off
Color Gamut: BT709
Edge Enhancer: Off

Color Temp: Warm
Gamma: 2.2

IRE Settings: All at 0 for 0 - 100

Note: I can't adjust the IRE vales well enough by eye, so I just zeroed them all out.

CMS Red Color: 5
CMS Red Tint: 0
CMS Green Color: 4
CMS Green Tint: 6
CMS Blue Color: 1
CMS Blue Tint: 7
CMS Magenta Color: 5
CMS Magenta Tint: 0
CMS Yellow Color: 0
CMS Yellow Tint: 0
CMS Cyan Color: 0
CMS Cyan Tint: 0

If anyone tries these settings let me know how they work for you.

I hope you don't stay gone for too long Phase. You posts on this this thread have been of great help!

Ed

Take care. We'll keep the flame going as best as we can

Sorry it's just the sharpness thing bugs me.
