OK, I've jsut bought an i1 Display LT and used it to calibrate my Samsung LA32B650 LCD. I'm pretty happy with the results. This software is awesome! Graphs are below, please tell me what you think I could improve.

looks pretty solid.

Looks good. Try using 20 ire instead of 30 and increase the color saturation alittle.

More information on the color calibration would be available if you compressed the .chc file into a .zip and attached it.

thanks for the replies. I will try using 20 IRE instead and see how that goes. also, here is a link to the chc file:

jeff6666p, when you say increase colour saturation a little, I'm not sure if I have a saturation control, I have the standard colour/tint controls, white balance controls and "colour space" controls. In the colour space I can set the amount of red, green and blue for each primary and secondary. So to increase the saturation, would I just increase the amount of red in red, the amount of green in green etc?

Looking at the Y values associated with the colors, it looks like you could work some more on the levels of blue, cyan and magenta. Blue is about 10% too high, and cyan and magenta are about 10% too low. (HCFR shows this on the delta luma line at the bottom of the primary/secondary color measures grid.)

After many passes calibrating my A650, I discovered that I got a lower CIE94 error on green when I added red to pull it in line between D65 and the Rec709 green primary. If you look at my CIE chart (http://www.avsforum.com/avs-vb/attachment.php?attachmentid=142386&d=1241978103) attached to my note (http://www.avsforum.com/avs-vb/showthread.php?p=15699476#post15699476) with all my charts, you will see what I mean.

Thanks for the suggestions! I have done another pass and this time I used 20IRE for greyscale and it seems to have helped. The midrange isnt quite as good as it was but overall the result seems better, plus the gamma improved. :-)

In regards to the primaries/secondaries, I read a few of your posts in the thread you linked to and I used your excel data solver to get target Y values. It seems to have helped alot. The blue Y value is still a little high I think, I will try to adjust that later. I have attached a copy of the new chc file so you can see what I mean.

Thank you so much for the suggestions! If you have any other tips they would be greatly appreciated.

Just a quick question... I noticed when comparing your CIE94 graph to mine, my greens and reds (especially green) seem miles off compared to yours. Is there any way I can pull the green further to the right on the graph (outside the white triange) to bring it closer to the target?

Essentially the primaries cannot be moved outside the native triangle; the outermost points are defined by how the LCD is built. You can move them along the edges or inside the triangle, by mixing a little of the other colors, but not outside. On my set, I've found the primaries measure differently using 100% or 75% stimulus patterns, because of a little non-linear behavior in the Samsung set. So if you choose to use the 100% patterns, the triangle may look a little bigger, with 75% stimulus patterns a little smaller, without actually being any different.

I would not worry too much about the difference in the measured position of our primaries, as it may be due as much to variation in the EyeOne devices as in the sets themselves. With a larger budget, one could reduce measurement variation with a better instrument, e.g., an EyeOne Pro.

Looking at your .chc file, it appears that the improvements in the color Y values affected the grayscale, with a little too much red at the lower end. You might see a little red shift in the Pluge pattern around 30%, and if so you might try a tick less red offset.

Have fun,
Bill

OK I've gone back through, taking all advice on board and I think I've got to a point now where it wont get any better unless I buy a very fancy video proccessor. Here's a link to the chc file. I'd be interested to know what you think. Perhaps the green primary could be a tiny bit better but apart from that, I'm pretty pleased with the results.

Thank you so much for your advice. I really appreciate it. :-)
