Hi there :) Yes, it's my 1st post ;)

Recently, I purchased the Toshiba 32WLT68 LCD TV (EU model) and as I already have Pantone "Eye One2 Display" hardware colorimeter (used for my PC LCD monitors) I decided to have a play with this TV. I've settled, for the beginning, with the ColorHFCR. Calibration was done on one of the HDMI inputs of the TV and I used Rapsody N35 HD network media player as source for the DVD test patterns. Of course, player was connected via DVI->HDMI cable to the TV set. Eye One2 was placed on the centre of LCD panel and connected to the PC, so that control, results verification and real time tuning is possible. Hopefully, this is enough to explain my set-up.

I managed to access the service menu of the 32WLT68, so that RDRV, GRDV, BDRV and RCUT,GCUT,BCUT ? values are accessible. By default, colour presets of this TV are still far from D65 (I measured that best case results for "Warm" preset was around 8000K). Anyhow, after initial calibration (brightness, contrast, deactivation of the dynamic contrast features and all other picture spoilers and side effects ... etc) and further tweaking of the RDRV/GRDV/BDRV primary gains from the service menu, I managed to hit the D65 steadily and IRE grey scale tracking was somewhat acceptable too.

After hour or so of the proper LCD warm up and further hour of tweaking, here are the results.


Colour temperature (IRE grey scale tracking):

By the way, is gamma tracking (with post calibration curve graph) possible with ColorHFCR ?


RGB levels:

You may notice the red push @ 40-50 IRE (reflected on the grey scale tracking) and I'm still unable to flatten this out. Not sure what to do, as even if I flatten this out at this particular IRE level, it's spoiling results on other parts. It's tricky to have "relatively" flat line.


CIE Graph:

Obviously, primary green and secondary colour points are spot on and they are virtually sitting on the vertices of the PAL/SECAM CIE triangle. There is slight shift on the primary blue and red, but I guess that this is probably characteristics of the TV gamut and colour decoder itself. Not sure if I have to bother with this or is it possible to align them at all ?!

Perceptively, PQ is miles better than with the "stock" set-up (after initial tweaking is done). Skin tones are fantastic as I can easily spot if someone have a subtle blush, have fake or real sun tan, too much (less) of the make up and overall "natural" skin tone of each person is more convincing. I'm greeted with natural, neutral and above all "calm" picture. Just as I like. There are plenty of shadow details in the dark scenes and bright scenery is vivid and colourful, but not "in your face".

Does the calibration graphs from the above looking "acceptable" to you ? Any further tips or hints are much appreciated. :) When evaluating the results from greyscale test, I noticed that some particular near-white shades are suffering from the subtle and pale "pink" tinge and few near-to-black shades from very subtle "green" tinge. Is this normal, as I'm still not positive that this is affecting the final PQ ? Also, I didn't touch the RCUT,BCUT,GCUT service menu values at all (all of them are 0). What are they used for at all ?

Thanks.

ps ... as this is my first post, I'm not allowed to use images or hyper links. Just replace the h**p with ... you know what ;)

Just by taking a quick lick at your greyscale the obvious. it's not very "flat", you still have quite abit of tweaking to do. Low end of the scale needs adjusting your above 6500K, mid end needs to be flattened out more, your below 6500K, mid-highend also needs adjusting. I'm not sure on how to approach leveling out your greyscale, I'm still looking into getting a colorimeter for calibrating. Just doing my research right now.
