Color calibration issues on Sammy HL-S4266W

Thread Starter 
While going through the DVE dvd and trying to calibrate the colors I ran into a so-far unresolved problem. After adjusting the color and tint (I thought tint should have been disabled using HDMI, go figure) using the blue filter, I can get the blue "squares" almost perfectly in sync with the filterbut the cyan and magenta "squares" are still off a bit. Also, while viewing through the red filter on the same pattern everything is quite closebut viewing through the green filter everything seems way off.

So, the question now becomeswhat to do?
I'll update with my settings later tonight.

Any and all help would be appreciated.

Not sure I entirely understand. For correct saturation the blue and white colors should be equalized and for correct hue the magenta and cyan colors should be equalized. Are you saying that no adjustments of tint would properly align magenta and cyan?

In any case, seeing inconsistencies with the RGB bars indicates a problem with the color decoder. It's not uncommon that all three color bars cannot be aligned perfectly. If the color decoder can be adjusted then that should fix the problem (I don't know about this display). If it can't, then you have to pick one of the 3 colors to use to set saturation and tint. The standard approach is blue. I've recently started using red, because the eye is more sensitive to inaccuracies in red.

Yes, I cannot attain the proper adjustments with the tint control so the cyan and magenta equalze.

That's odd. Did you try the red color bar w/ red filter? I know this is available on Avia. I'm not sure that DVE includes this.

Yep...I've tried all 3. With the blue filter as stated the cyan/magenta are off. I can adjust the tint to get cyan to be right on....but then majenta is waaay off. I can't adjust it enough to get majenta to be correct regardless. The green filter is just way off in general. It doesn't all jive like the disc shows it should. The red is a bit off but not to bad. I'd say it's a tad better than the blue...but not by much.

Again, I'm not sure I understand. The point is to get magenta and cyan indistinguishable from EACH OTHER when looking through the filter. How could cyan be correct and magenta be incorrect? What would this mean?

Per the DVE's instructions while looking through the blue filter and the test pattern I adjusted the color control so the white background is indinguishable from the blue squares. I then adjust the tint so the magenta and cyan are as close to eachother as possible (still a bit off). Now....there really is no more info I could find, but all the reference images show the cyan and magenta the same shade blue as the filter. Mine are quite a bit darker while viewed through the filter. Am I wrong to assume this? If so...why the hell do all the "this is how it should look" pictures show all the shades of blue the same?

After running through the DVE here is the settings the give me the closest results (still seem way off):

Digital NR - OFF
DNIe - Off
Mode - Movie
Contrast - 50
Brightness - 54
Sharpness - 0
Color - 33
Tint - G40/R60
Color Tone - Warm2

That's it. That's all there is. You are making this way too complicated. If blue and white and then magenta and cyan look indistinguishable from each other when looking through the blue filter, then color and tint are set correctly. There is nothing else to consider.

Well...magenta and cyan are quite distinguishable from eachother. I can see a difference between the two regardless of my color and tint settings. Alsowhile viewing through the green filter I can still visibly see all the colors.

If you scroll down the page here ... http://www.ramelectronics.net/html/V...libration.html you can see what I would expect the green patter to show.
