So I have a Samsung PN50B540 Plasma (I know, I know, the i1Display LT is not the best for plasmas) but I just wanted something with decent enough calibration ability.


Now here is my question. I will probably be using HCFR since I cant afford to drop another 200 bucks on ChromaPure or CalMan, so is there an HCFR guide anywhere? I have no clue how to use it, or how to even get started calibrating (yes I read the stickies, it doesnt actually explain how to use any of the programs it just states what to calibrate).


I just need a beginner's guide to using this program (the website is in French..) or some other program that may be easier out there for free. I have never calibrated a display before (I used the DVE blu ray disc and eyed it out, but have never used a colour meter before).


Any help would be greatly appreciated, even if just a link to somewhere else.

Ok Im going through calibrating on a friend's LED, and I am at this part:

Quote:
For advanced users that want to a less subjective way of doing this, there is actually a more correct way of setting brightness:



Set the contrast as in the previous section and record the Y value (light output) on the 100 IRE window pattern.


(Spyder2 users only) Increase the sensor read time temporarily to 2000ms by going in the "Measures -> Sensor -> Configure" option.


Display the 10 IRE window pattern.


Adjust the brightness so that the Y reading of the 10 IRE window pattern measures as close as possible to 0.65% of the Y reading of the 100 IRE white pattern. For example: At 100 IRE we measured a Y value of 47.387. 0.65% of this is 47.387 x 0.0065, or a Y value of 0.308. We would therefore adjust the brightness until the Y value reads 0.308.


This sets your gamma at 2.2 for the the 10 IRE window pattern which is typically the perfect gamma value as explained previously. In most cases this will be the correct setting for brightness. If your display has an unusually high or low gamma or a non-linear gamma, this method may give you the wrong result such that you can't see the 2% or 4% PLUGE bars (black clipping) or the black background is far too grey. In that case, adjust the brightness setting using the traditional method described previously using the PLUGE pattern.

But every time I switch from the 100IRE to 10IRE, and switch back to HCFR, it is ALWAYS locked up. The only way to end the process tree is to remove the i1 display LT from the usb port and then reboot HCFR, which I then have to proceed to re-calibrate the LT.


I cannot get it to accurately display 0.65% of the Y reading from the 100IRE value because the program just keeps crashing.

Actually scratch my last post, it was an issue with the meter.


However, after calibrating my friend's LED (maybe its not meant for LED) it had worse RGB luminence readings and the gamma was at about 2.9-3.0, however when he used some random numbers he got off of a website, the results for greyscale were near perfect.

It's not ideal for LED backlit (or edgelit) displays. I believe that's due to the different, much narrower spectrum of led lighting over CCFL lighting. It should work fine with CCFL-LCD and Plasma, I have had nothing but great results with those display types.
