The KRP also has its flaws...

I guess it is as close as it can get to perfect, at least for a couple of years more before the other players catch up and exceed it.

If you look for perfect display, it must have the following ingredient.

1. Meet or exceed 100% for CIE gamut.
2. 11 point gamma correction.
3. greyscale colour temperature control (RGB gain/cut)
4. full working 3D CMS.
5. Very low black level.

Then with a good probe, you can adjust it to the BT.709 colorspace standard. Unless you are still watching DVD, you need to recheck BT.601 colorspace too.

Hmmnn..

I tink those using DVE n Avia calibration discs are jus touchin de surface here.. Bro A here uses much more advanced ways to calibrate..
Not tat I m knockin those 2 sofware.. I use them myself..

That is what I have. But you need to have the filter for DVE. Maybe Anfield can help do calibrate for my projector?

Pm.. him ..

He is veri accomodatin..

On de filters.. U mean DVE dont include de filters?? My Ovations Avia includes tis in de pckg.. thou' its only d plastic colored tingy..

D

If your projector had blue only mode (which turn off red and green) then you don't need the filter. Even the tint/color control is not accurate based on the Calman reading. If you have CMS, just leave tint/color at default. It's very easy to screw up the color using tint/saturation control.

My personal opinion is that for getting colours right, u need a meter (preferably a spectro). Also a working CMS is a must, else the display must track Rec 709 accurately. But a 3D CMS is the way to go.

Bro anfieldude,

It is possible to post the best possible setting for KRP-500A ??

I don't have a KRP-500A to do that.

he has 600M

anyone has callibrate toshiba zv?

All,

Do let me know what other stuff you would like me to cover in Display Calibration or anything related to something that is not brand or technology specific. I will try to put more details in the 1st page. If there is enuf interest, I don't mind adding a step by step calibration guide to use a meter to calibrate. However, there are others that do it well.

Bro anfieldude can setup a team to train video calibration in Penang and those interested can fly there, pay a fee n attend the course n share ideas together. and if anfieldude doesn't wanna to collect the fee, we can donate it to charity :)hehe

Added on April 24, 2010, 11:09 pmFrom what I've read so far in this thread, people who is interested and have technical knowledge will probably understand at least 60% and above of what is mentioned here.

The rest are probably scratching their heads trying to figure out what those terms (d65,rec 709, +512, 3D CMS, etc).

Maybe do a simple definitions on what these terms and meanings are.
like, why we need to get D65 and what it means, etc

Then everyone will understand further.

Thanks for the suggestion. I will update the material when I get the chance.

anfielddude,
apart from the sizes (600m & 500a), is there any more difference in terms of specs and hardware between those two?

I posted the reply in the Pioneer Thread. See link below.

Anfield & Gang, my first calibration on 508XG. Any suggesting for further improvement is most welcome.

At first, I was surprise to see the Gamma curve , too good to be true on the original setting. Until I realized the RGB and Color Temp were quite off.

The whole calibration process took so long (~3 hrs) for newbie like me. At one hand look for how-to procedures and on other the hand try to familiarize the software. But the whole learning process is fun and rewarding. Better do it at late night so that no one is ka-ka-chau-chau. I really recommend AV enthusiasts to try on this, either DIY or pay professional calibrators to do it. Imaging the significant improvement you can get from the existing hardwares just with a small price to invest versus your HT investment cost. Now, I'm realize for almost 30yrs, I am looking at something off the standard

On the CIE curves, I found the R & G points slightly off from target. Already tried on the CMS setting and still cannot get the (x,y) on the dot. Any suggestion?











Note:
a) Meter: Xrite i1 display LT.
b) Software: Color HCFR, Color space standard: HDTV-REC 709
c) Test disc: AVS HD 709
d) Left graph with original settings and right graph with new settings.

gocitygo,

Pls post the .chc file so I can take a look a the data.

I suppose u calibrated in Colour Space 2 and the 1st graph is with Colour Space 1.

For the Pio's I would not touch the CMS more than +/- 2 clicks as it effects greyscale quite badly. I suspect there is some clipping but let me take a look a the chc file bfore I comment.

Wow, you are keng chau. Yes, the original with Color Space 1 and the new with Color Space 2. I found out the Color Space 1 too much Red and need to cut a lots during Grayscale calibration.

If don't adjust the CMS too much, how to get the (x,y) for the Primary & Secondary colors?

Attached is the chc files. Thanks
