Anyone using Color Management System (TV/ PC Monitor)

[Jerri]

Hi there, i saw quite some people here with colorimeters, and maybe somebody is using a Color Management System like an external Video Processor, that has CMS on it?
On the PC + Audio Thread someone told me something like this: "don't say ripster, that his Speaker Frequency Chart is off, it's like your saying his white point isn't D65".
And due the fact that here are some geeks, i thought the chance is there!

I for myself use a Lumagen Radiance XE with Primary/Secondary/White, 21 Point Gamma and 21 Point Greyscale Correction. It's corrects my TV (often using that as PC Monitor), which is already really near where it should be.



So most times, the difference is very subtle (the corrected Red luminance and hue f.e.):


But sometimes the difference really is there:


The images were shot with a cellphone camera, but the brightness was fixed and the white point was set to daylight.
The corrected image is in both examples the lower one. So is anybody here with anything like that? Or am i to geeky in this case :biggrin:

I've used a colorimeter with my PC for some time now.   When I used my Trinitron CRTs I used the GPU LUT method of correction.  I now have an NEC LCD2490WUXi which has integrated hardware LUTs and a software application which automatically sweeps the colours and programs the LUTs.  Works great.

For my TV I used the same colorimeter with ColorHCFR and did what I could to adjust greyscale and colour temp from the service menu.  That being said, almost no adjustment was necessary get be nearly in line with ideal D65 curves according to my gear.  I think I was dE<3 with very little adjustment.

Neither is an external, inline CMS system like you describe but at least kind of on topic.

I'm not...yet. Currently trying to decide if the X-Rite i1Display 2 is worth US$200-250 or so. (The same hardware colorimeter apparently comes bundled with different software packages, like a cost-reduced "LT" package from X-Rite and the more expensive LaCie Blue Eye Pro package.)

Not just because my FD Trinitron G1s are in dire need of calibration (especially since something's off about the red gun in the P1110 and the green gun in the GDM-5410, and I can't pull the necessary data to correct that in WinDAS without a colorimeter), but also because my 2730p's LCD (Hydis AFFS+; one of the better-quality LCDs you can get in a notebook, albeit 6-bit color channels from what I've told) renders red as somewhat pale and orange-ish.

I'm also hoping that it'll help me fine-tune gamma across multiple luminance levels, much like the test image on this page.

Not looking to do any professional color-critical work, just wanting to see things as their creators intended...

I tune TVs by eyeball with a reddish cast using porn.  PCs I calibrate with a colorimeter.

Hehehe! Yeah, i eyeballed my TVs (last one was a Sony XBR 5), too and i was really fine with that. But on this TV (XBR HX909), i always thought, i miss something. The Sharp UV2A Panel gets nice completely "non cartoonish" colors and a black black (due the local dimming).
My eyeballing wasn't that bad, the blue was a bit to low (6350k temperature), so the picture was a tad yellowish, but there was always something that looked wrong for me.

So i bought a Radiance XE (the ones on ebay with the Sencore By Lumagen Logo) very cheapish, for 1550 Euros (2100$) including Shipping and Customs fees. Yeah i know, that ain't cheapish, but in germany you pay 4500-5000 Euros (6100-6750$) for a Lumagen Radiance XE 3D, no joke.

And with the Primary/Secondary Correction and the 21point Correction in Gamma and Greyscale the image looks really awesome. Like i said, often it's a subtle difference, but on some movies it is quite heavy.

Besides that the Scaling is great, and i can transcode everything to HDMI. I'll need that, when i (damn what's the word) i paint my walls, make a new ceiling and floor in my living room etc.
First i wanted to buy a DVDO iScan Duo for that reason, but the Lumagen was only a tad more expensive, so i chose that one.

That's the story.
Oh yes, my Meter is a X-Rite Chroma 5 with some special LUTs (one for Sony LED_LCD f.e.).

No dice, that's almost as much as I paid for my TV. Diminishing returns and all that.
