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!

Are you saying that you were able to match all primary and secondary colors and grey perfectly? I am simply amazed by how little you had to adjust to get all colors right. It once again shows just how different these panels are. With my 60" non-IPS panel it is impossible to get red to match the rest. Blue can be matched with very few changes, but green is already so far off that it simply doesn't make sense to even try to come close.

The strange thing is that the picture looks spectacular after calibrating for blue only. I'm happy for now

BTW, at which contrast setting does your white clip at 235? You only mentioned the colors. My white clips at 235 with a contrast of 99, but blue at 235 clips with a contrast of 93. That why I have it set at that. Red and green clip much later due to being way off compared to blue.

Dude, you gotta stop with the sharpness. You did not cause any harm to your set. Leave it at 50 now and you should be good.

Thanks for the replies, not getting notifications oddly, need to check spam. I'll skip the headphone workaround for the moment as that link I posted was for a $65 DAC.

My question is moreso can you use a non 5.1 DD converter? This is JUST for streamed movies in a mkv container encoded AC3/AAC 6 channel audio that i need to get to an older receiver. Now i only have a 2.1 granted so the future means a new receiver and a 5.1 or larger setup.

Can a non Dolby Digital DAC convert 6 ch DD to i guess 6 ch analog (prologic ?)

thx!

Does this sound like a reasonable method to use for someone without the proper hardware/software to do a proper calibration?
Only thing I would do differently is resetting the IRE's before adjusting the colors. But of course you can just go back and look at the flashing color bars with the filters again to make sure that zeroing out the IRE values didn't affect the color settings.

Also, make sure that you've 'neutralized' your bluray player before starting. For instance, my BD60 has settings for Black Level (darker / lighter), Picture Mode (normal, soft, user and... something else, can't recall). You want any processing by the player to be off.

Maybe I got lucky with my panel, or maybe my eyes are as bad as my knees, and I'm just seeing what I want to see.

I set all the IRE black level settings to 0 across the board. I didn't notice any bad color variance using the greyscale ramp pattern.

I was able to get all the primary/secondary colors to match up pretty well. As far as the greys, are you talking about using the same test pattern for those, or some other pattern? When using the B1 - Flashing Primary Colors pattern, the blue and green areas seemed matched up just right, including the greys. The red pattern was very slightly off on the grey, but still looked pretty close.

I'll have to recheck the clipping levels more closely for you this evening.

I may have misspoke about my step order. I did zero out all the IRE settings before doing the other adjustments. I'm pretty sure I did kill all the helper settings on the BD player, but I'll check again this evening.

Thanks!

Hi all, I just picked up the 42LD550 last week for a great price. This is my first LCD HDTV so I'm still learning a lot and stuffing as much info as I can into my head.

My first question is how is the input lag on this TV? Since this is my first LCD I have no clue what to look for other than the time it takes from me pressing a button. Does anyone have any pictures of tests? I saw that Vexx guy's post however on another forum I heard better results but I can't confirm it.

Second, what are the best settings for game mode? I want the lowest input lag possible.

Finally, I have a Comcast Digital Cable box that's connected via analog (no HDMI output), what do you recommend for the best settings? Especially for sports?

@ Veeshun

Not to be rude, but please try to search the thread. Everything you asked has been discussed at length. Many different settings have also been posted. Feel free to try them all or do your own calibration using the excellent AVS HD709 disc.

Yes, I meant the grey in the B1 pattern. Red, green and blue are supposed to be matched with grey as well as the corresponding secondary colors. Sounds like you have a great set.

Makes me wonder if that is one of the differences between the IPS and non-IPS panels. If more people here could do the same, please . I'd like to know if it's just my set that's pretty far off with red and green.

I hear ya Henry. AVS HD is burned, verified, and ready to go. It's now finding time in the evening to play around without getting yelled at I've got a "virgin" Expert 2 just waiting to be played with

I rechecked my clipping levels and here is what I found:

White clips 235 at contrast of 99.
Blue clips 235 at contrast of 97.
Green clips 235 at contrast of 99.
Red clips 235 at contrast of 100.

I fiddled around with the CMS settings again and modified the settings a bit. Here's the latest.

Red color: 5
Red tint: 0
Green color: 5
Green tint: 5
Blue color: 1
Blue tint: 7
Yellow color: 0
Yellow tint: 0
Cyan color: 0
Cyan tint: 0
Magenta color: 5
Magenta tint: -4

After having messed with the settings again just now, the only obvious mismatch I have is Red/Magenta. They just won't get together properly. All the greys appear to be just about right.

I'll try to post some screenshots to see what everyone thinks.

Ed

Edit: I think I have an IPS panel. I have 'W' in the proper place, but haven't checked with a loupe.
post #3824 of 5070
So you could technially run contrast at 97. See if you get any discoloration in the greyscale ramp when you do that. That should give you the brightest picture with the most "pop" possible. If you find that running such a high contrast is simply too bright, you should dial down backlight to the point where you don't get eye fatigue anymore. That is the recommended way of adjusting light output.

Sheesh fine then, I thought this was a friendly thread....for your information I've been doing that for weeks and have turned up empty on the 550 especially on gaming info.

This is a friendly thread, and extremely helpful, but if you can't find what you need for gaming on the 550, there's probably not a whole lot of gamers here using the 550 for that purpose.

@sheshechic

If you see this I've got a couple of questions about the 210 which aren't really OT for this thread. Mind if I pm?

Otto is right. I've been posting in this thread from the beginning, and there simply hasn't been much information on gaming. It seems that most posters here are more concerned with making their sets look as good as possible for watching Blu-ray and HD programming.

As far as input lag, there are two websites that you can use to test with a computer hooked up to your TV:

http://tft.vanity.dk/ and http://www.lagom.nl/lcd-test/response_time.php

As long as you turn off all picture processing, especially TruMotion, you should be fine. You could also try the built-in Game mode, which supposedly has the least amount of lag.

Try Phase700B's various picture settings to see what works best for you. When you look at the thread from the main Display forum, there is a separate attachment option that list every single file ever uploaded to this thread. Phase uses dates in his file names, so it shouldn't be hard to find the latest.

Just picked up a 42LD550 , after getting a 26LE5300 for a bedroom...
one key usage, is DLNA video file playback.

Big problem: it plays back all my HDV MPEG2 files (1440x1080), with squished aspect ratio- too narrow!
I've tried the video Play menu option, full vs standard, no change!

The same files play fine on the LE5300, from USB - the fast fwd/rewind works better there too.. maybe it works because it is 720p, and has to scale anyway?

I also tried some photos, and they are all "broken" - size is wrong (says 640x480), and I get the little "attention" triangle/exclamation point icon). The thumbnails mostly look OK.
I tried some from a USB drive and are OK.
I've updated the firmware to 08.02.16, and no change!
Does yours work on HDV, or other semi-standard resolution/aspect files?
Do I have a lemon?

Edit: This is a return/used item from Amazon, seems completely intact/working, although they gave the wrong remote- no Netcast button- explains why I couldn't find Netflix etc... Harmony workaround for now..

There were some earlier posts for lag time on a xxLD550 and my recollection was 47ms to 67ms input lag time.

The best settings to use is Game for Picture mode. You didn't mention what kind of game system you have, but it you use the "Search Thread" option at the top right of the page here, you can search for "xBox settings" or something like that. It would also depend on what inputs you are using.

Check Post #306 and Post #314 as well as Post #1 for most settings on a 42LD550.

@Henry

I have started my AVS HD adventure! So far, just aspect, color (temp), brightness, contrast. I'll put some numbers up when I get a little more comfortable using the disc. I need to learn a little more about the brand-spanking new Panny 210. Hopefully sheesh will have some pointers for me.

Great to hear, Otto! Looking forward to your results.

Oh, and look!! Nick is back already

@ cgould

Wish I could help, but I have zero experience with media playback on the TV. Maybe someone else here has some info.

Thanks Phase! You have a great thread here. I'll post back when I try your settings. Also I don't notice much lag, which is why I couldn't believe Vexx's test results from a couple months ago. Great TV btw!!!!

I can't offer any answers either - I don't do any streaming.

I do have an observation though. 1440x1080 is a 4:3 ratio, so I would expect this to appear with the normal 4:3 black bars on left and right side of the picture. Is this the what you are refering to, or is the TV squishing it even more and distorting the picture?

HDV is like widescreen SD: it is anamorphic.
The pixels are not square - the horizontal count is 1440, but the player is supposed to expand it to fill 1920 "square" pixels worth, eg the whole screen width.
Just like widescreen vs 4:3 DV or DVDs, are both still 720x480ish of pixel resolution.

The file headers should include the pixel vs the visible/rendered resolutions & aspect ratios.

I've never seen a problem with 1440x1080 HDV MPEG2 files before on any player, and as noted, the 26LE5300 plays it fine. My LG BD390 bluray player plays the exact same files back fine, although it won't fast fwd/rewind them, at least the 42ld550 does some trick play transport...

I tried some other test files I'd collected over the years, and several 1440x1080 or other width files played OK (some VC1, H.264, etc), others played wrongly...
M2TS (raw capture mpeg2) files stuttered a lot, as did some H.264; others played fine.

Well today I put on 2 1080p videos I downloaded from youtube and both ended up appearing kinda crappy.


So I switched through the settings (usb mode) about 100 times in 5 minutes. Again are you guys sure that kind of harsh/constant settings switching doesn't do anything? Cause I swear my tv looks less sharp now.

I don't know, I wouldn't consider anything downloaded from YouTube a reliable source of high quality video. If switching settings could cause harm to a tv then I would think that the mfg wouldn't make that available to the end user. I've switched through all kinds of settings on my tv since I bought it in January playing around and getting used to it, especially during calibration, and haven't had any of the problems you seem to be having. Sounds like you should pick an input, reset to default, and start basic calibration.

Thanks for the HDV education - it is appreciated.

Based on your description this sounds like a firmware shortcoming. Hopefully someone will be able to at least confirm that they are seeing the same issue with this format. Or better yet, provide a solution.
