Excellent settings ran those just now.

I reference using the Avengers right at the 32 minute marker...there's red hair...blue jeans...red shirt....lots of brown a little later as well as tan shoes on Banner all while they are in the sun.
Also used Prometheus right up until the title is shown there are red cells dividing and the red hues are a good marker....the aliens face on the mountain as well is a blueish hue good sharpness makes u feel like a dermotologist as your watching.

I really liked your settings. I saved it to ISF night. Does that mean that unless unless I run ISF night profile it will not use those rgbycmw settings?

I had my own concoction which I liked to run under whisper mode becuz I found that normal for my eyes anyway was always a bit too bright.

Anyway I know for certain the color temp changes should work via any profile...I switched between the two...yours(isf night) and my previous. And they are somewhat alike except mine does not let things hide in black as well.
The main difference tho is that I am now running Normal lamp and I dont find it as offensive as before.

These are my saved profiles settings which have def been enhanced with something from your settings....even if it is not running the saved isf night rgbycmw profile settings altho id like to think that it is:

picture tab basic:
bright 49
contrast 55
color 68
tint 0
sharp 6

picture adv tab:

Black 0 ire
Clarity -> detail enh +3 , chroma and luma +1
ct normal

gamma 2.2
bc off
color management......all colors range 0 all colors Saturation +51
dyn blk on
Iris 9

It is very similar to your settings,... colors run a slight nudge hot...but in IRE 0 the blacks are just black enough to define black but the shadows dont just hide things in darkness so easily.
Even more impressed than before so im certain in the minimum your ctemp nudges have helped...and id like to know if your CCA settings are still contributing here.....this is a real sweet spot...i can watch both these flics all over again.

Give it a try if you get a chance...I realize the color setting may seem high but it renders beautifully. Thanks again im able to run Normal lamp much more agreeable than before.

On my PC (RGB mode) this is a simulation of what it looks like, zoomed in:





The outline is ALWAYS two pixels to the left and right of a strong color. There is never anything on top or bottom.


I've tried all kinds of settings in the service menu (playing with color wheel index, sharpness settings, clarity controls) and I can't seem to get rid of it. It bothers the heck out of me, even though during movies it seems to be ok at my normal viewing distance.


Any idea why my W5000 is doing this? The effect is not seen on my other displays, so it isn't a display driver issue on my PC. I even tried different graphics cards.


Text looks really odd because of this - especially if the text is red or purple on a white background - makes it look fuzzy!

Have you ever tried feeding 4:2:2 YCbCr to your W5000 and see if it makes any difference in this case?
I guess also one thing worth to try would be testing chroma resolution patterns using Spears & Munsil test disc and see if there is any difference in chroma resolution between RGB, YCbCr 4:2:2 and YCbCr 4:4:4.

Yes. I would also suggest not to try forcing primaries at 100% saturation levels too much but to consider also lower saturation poi0nts 0-75%.

So my workflow for CCA will be :
- Entering measured value
- Tuning all x,y desired value
That will work.

- Measuring Y of a Color and multiply by the Reference Y
You multiply measured white Y by reference Y for each color.

Quote:
What i don't understand is : i need to reach the new Y calculated by tuning or simply entering the new Y on desired Y ?
You modify Y by entering new desired Y value then you check is it ok by taking readings and looking at HCFR Y-field. To check if they are correct is to compare each color (RGBRYM) to measured white.

Example: Your white reading in HCFR is 15.000 then your red should be 3.189 and green 10.728 and so on. Then you go to ISF CCA and change your red, green and so on Y-values up or down depending on the readings you just took. Then you again measure all colors and white and again calculate what Y your colors should be compared to white Y. Then repeat procedure.

You need to do this many times because every time you change any Y-value it will make something else moving too. But once you have done this many times your changes are so little that you will reach your goal.

Also remember that adjusting Y's will change x and y so adjust them also during Y adjustments.

Also one in a while take full gray scale readings from 0 to 100%. If it needs to be corrected use ISF CCA white x and y but leave its Y at 1000 always.
Some peoples use service menu color temp settings to adjust that but I rather use only CCA W at that point.

I know this sounds messy but you will get hang of it by following that procedure.

Once you have reached your goal try moving to 0%, 25%, 50%, 75% and 100% saturation measurements and adjustments to get all saturation levels as good as possible. When you get this right you have nearly reference quality display.

 

Ouh, I was hoping that this would be a whole lot easier =o

 

I'm about to buy the W1070 that has that ISF menu: http://www.audiovideohd.fr/i/imgs/17106-4.jpg

 

It's got that CCA table but you can also specify the xyY coordinates of the primaries and secondaries apparently.....so I was hoping to be able to input the Rec.709 gamuts values et voilà? Perfect gamut and 0% drifiting saturations in HCFR? Not quite? I really want the W1070 to abide by the Rec709 gamut.

 

Thanks for any advice!

guys, I don't understand....can CCA be used to put back the drifting green primary on the exact Rec.709 xy coordinate? It would appear not, so if this thing can't move primaries, wth is it good for? frown.gif

That's the W1070: http://www.audiovideohd.fr/album-Benq,W1070/17120.html

Apparently, that's a no-go:

This is normal behaviour for these controls but it does not mean you cannot get pretty much perfect picture. Concentrate also saturation below 100%. If you can get saturations 0, 25, 50 and 75 perfect don't worry if 100% is a little off. It is much better than just having 100% right and others completly wrong.

 

 

Ideally I would like to make it spot-on Rec.709 and then map gamuts from SMPTE-C and EBU from within the PC, but apparently that will be impossible =(
