Hi Anfieldude,

I calibrated the Brightness/Contrast of my Panasonic AE300 projector using AVSHD basic patterns as advised and is so far very happy with the picture quality. Source is my new Samsung BD-C5500 connected via component output.

Have not attempted to set Color/Tint as I do not have any filter or meter. Is there any other adjustments that you will recommend that I can do by eye?

Not really. I guess the only other one could be sharpness.

Yes... did that too. Thanks for sharing.

There's only that much that can be done without a meter, but doing the basics by itself improves quite a bit.

Need to recalibrate my LG 42LX6500

the blacks are sooo gray... I dunno why...

Sorry for this noob question.

Does LCD TV need to perform calibrations?
If yes, then how to go about doing this?

All displays benefit from calibration. It sets the display to its optimum to play back content as close as possible to the targets that they were mastered to for viewing.

If u read the 1st page, there are a few ways to do it.

U can do basic calibration by following the steps outlined there.

Of course, there is only so much you can do with a test disc and eyes.

To carry out advanced calibration (greyscale, gamma, colour points etc), u would need to invest in a colorimeter or spectrophotometer to do it. Or u could hire someone to do it for u....

Have u set the brightness correctly as I outlined in post 1?

Do blacks become grey in dim environment or even bright environment?

Is the display screen a matte screen or a glossy screen?

Is light hitting the display when it happens?

Is it only in 3D mode?

where can i source the xrite i1 locally especially in penang?

there's a few company listed in xrite in klang valley only

Are u looking for the eye One Pro or the i2 display lite?

The distributors in Klang don't really carry too many spectros.

is it a warm color temperature is the correct than natural?i dont understand my most of calibrated hdtv use that setting,it look yellowish to me

sorry for noob question......

Warm "normally" comes closest to D65 white. However, the white balance settings (RGB gain/cuts) also need to be set. This can only be done correctly with a meter.

D65 white tends to look different than "blue" whites that most people tend to think is correct.

D65 is the white point that movies are mastered to.

thanks,now i understand why.

Something for diy/home use, i2 display lite i suppose, and also colour checker passport, my passion are movie, gaming wit a bit of photoshop

Ok. I know some photo shops in Komtar carry the Spyder. I would advise against it. My advise would be to either google Calman or Chromapure to buy a bundle of the meter and the software. U could also get the meter from B&H photo or Amazon in the US and use the free HCFR. Both Spectracal (Calman) and Chromapure ships to Malaysia. Most likely tax for colorimeter is 10%. Let me know if u need my help.

I also remember seeing the i2 display lite once in komtar photo shop but the last time I went it was not there anymore. It was extremely expensive compared to US.

Colour checker, I'm not familiar and experienced with as I am more into displays an not into photography/photo related. The targets might be different.

The $49 offer for the colorimeter u mentioned in the thread earlier is it still ongoing? How limited is hcfr compared wit calman in ur experience

No more. It was only for existing Calman users anyway. HCFR works fine for a diy. The support for meters is limited and there is not much customization u can do. Chromapure and Calman are much better in that regards. But it does what its intended to do.

Just bought the X-rite i1Display LT from amazon, then spend four hours to learn how to use colorHCFR for my Optoma HD20 projector

Below is the result

Luminance (Before Calibration)



Luminance (After Calibration)



Gamma (Before Calibration)



Gamma (After Calibration)



RGB (Before Calibration)




RGB (After Calibration)



Color Temperature (Before Calibration)




Color Temperature (After Calibration)







I'm quite satisfy with the RGB and Color Temperature calibrated result, but the gamma is not that good, I tried few ways to make it flat such as changing the gamma curve and offset, make a few tries and I still unable to get it flat at above 70% grey, I wonder how to adjust the HD20 parameters to get it right

Kiding,

U r seeing clipping in the high IREs. Its typical if u r running contrast too high. Pls try reducing contrast until the gamma at the 90% stops clipping.

Pls send me the HCFR files and I will take a look as well.

Okay, thanks for the suggestion, I will try to correct tonight.

Below is the HCFR files, please have a look.

Will spend some time later to review the data.

There are various gamma options on the Optoma. I believe Cinema was almost 2.5 and PC was close to 2.2 the last time I calibrated one. Reducing contrast shd elimnate the clipping.
