Hello. I've been using this disc through my PS3 to calibrate my Sony KDL-50w800b and noticed something strange on the color clipping screen. Red and blue stop flashing past the 235 line as they should, but green flashes all the way through to the right end of the screen. Here is a poor photo of what's going on, but you get the idea: http://i.imgur.com/iLAt0II.jpg Red was initially clipping before 235 but I brought the Picture (contrast) setting down 2-3 notches and it cleared up. In this photo it may look like red and blue are clipping too soon but they are visibly flashing up until 235.

I was wondering how bad of a thing this is, and what settings I might try adjusting to solve this? One thing I wondered about is the white balance, which has 6 settings. A gain and bias for each of the three colors. I don't have any sort of sensors or meters, but I do have blue, red, and green filters from my GetGray DVD. If it helps, I've been feeling oranges may be too red.

Thanks!

See what effect Color has on the color clipping.

Okay, I experimented with the Color setting, and if I turn it way up, the green eventually clips where it's supposed to, but then all of the flashing bars for red and blue disappear, they are clipping at every number. My blue filter combined with the flashing blue/white boxes test (http://i.imgur.com/OsiOl0H.png) tells me the correct color setting is 54, and to make green clip at the right point I had to turn it to 69.

When I view this pattern http://i.imgur.com/8CWoGJb.jpg I can see each box's individual defined shade, it seems to look fine.

I'm worried that those flashing green bars not clipping is a sign that the colors are out of balance or something.

These things don't always work perfectly, and you may have to compromise between what the clipping patterns are telling you vs. the filter vs. real material. The behavior can also vary between different viewing modes. I know it does on my Panasonic 50ST60. Extreme changes to Color are probably inadvisable, and 54 for a Sony LCD sounds a lot more right than 69.

Thanks for the feedback. I guess it sounds like as long as the image doesn't look severely imbalanced when viewing content, that I shouldn't worry about it. I tried the Hue setting which I believe is the same as tint, didn't look any better in either direction so I've left that at zero. The colors seem all right for the most part. I trust the blue filter.

I can't seem to get access to the Wuala files, so I moved the w6rz links to the first page. I think the downloads should now work.
I had to use the spectracal links, the w6rz links are currently downloading at only a few kb/s.

Download my IR hex codes for the Denon AVR-4810ci and other Denon receivers here.
For Logitech Harmony support, ask Logitech for the Denon receiver in the account kmickunas.

I've been trying to download the disc to burn and I keep getting download failed. Not to mention the downloads are taking forever and always failing at the end. Is there a torrent somewhere? Or maybe a link that's hosted on a more reliable, faster server?

Look at my post just before yours for the link.

Sorry to hear that. However, the server is just a regular shared host. It will usually be fine, but may have periods of funkiness.

I just tested it right now, and it sustained 15 Mbps during the entire download.

Since alluringreality changed the links on page 1, the traffic at w6rz.net has tripled.

Are the spectracal links up to date? They look like an older version.

I don't know about the spectracal links. And I don't know how to determine version on these. I'm trying the w6rz links again and am getting between 60 and 70 KB/s. It'll speed up occasionally, but I have yet to see 100KB/s.

If we could get some torrents for these that would be helpful and take the burden off your server.

Ah, I just noticed the iso I downloaded from Spectracal is named AVCHD-v1_2b. So it is older.

Unhappy

I'm not sure what I'm doing wrong here. I am trying to use the mp4 version to calibrate my PC monitor and my TV, which are both connected to my PC (cloned). I fired up the first black clipping test and my monitor does it fine, it flashes from 17 up. My TV doesn't flash any of the lines below 21, though, even with brightness, contrast, backlight, and sharpness turned all the way up. The monitor is an Asus VW246 connected via DVI, the TV is a 40" Changhong LED40YC1700UA connected via HDMI, and they're connected to my PC which runs an XFX 7870 Ghz Edition.

Sorry if this has been asked before, but I'm not sure which file I need to download to burn on a Mac. I have Roxio Toast and a BD burner, but these don't appear to be in a format I'm used to seeing to burn disc images.

Also, do the THX glass work with these tests?

Thanx.

Hi, Blue Filter Glasses are useless for displays other than CRT.

The blue filter was an old method that was designed for CRT displays where they had only color and tint controls only and meter/software were not available these years.

Now most of the displays are coming with CMS controls.

Blue filters (on CRT) can work where for example the Red Primary is fully saturated and have no blue or green...blue primary has no green or red etc....But a fully saturated Primary needs to have the other 2 primaries added to be able to de-saturated it to it's target....so viewing throu the blue filter you will have light coming from all three primaries and this will make it's blue filter porpose of maching the luminance method no longer work.

This is the reason that blue filter fails to color/tint test on a fully calibrated CMS display.
