Sony Oled calibration

[Marcus Herrick]

I spoke to a Sony tech guy a few days ago. Apparently the software for the X-Rite, hasn’t been released yet and he said he was going to get training on it in the next month. In the meantime, your pretty limited in your calibration options to the Konica Minolta.

I have mine with Sony at the moment to calibrate it, as it arrived with a very warm / yellow white point.

I’m even having problems with cineprofiler/cinespace. HAs anyone had any luck properly profiling the display. Best results were to tell cineprofiler its a CRT. I’m using independent profiling with a i1Pro.

I tested this monitor and I recorded a video, results was like a crt, with the same banding refresh issue.

I think not any calibrator can work with this monitor. I think you need to have sync between both.

In the other hand, eye one pro is not so good with low IRE or high contrast monitors like this. I recommend more expensive colorimeters…

I’m going to have a crack at it today. I’ll use quick 1d ramp patches to see what works before doing a full 3d, when I tried in December I found there was a preferred refresh rate (can’t remember if it was 50/60/24…) that got no errors.

Also, for better low IRE performance I’ve been told that letting the probe/sensor rest in the room in complete darkness (or covered so absolutely no light enters the probe) for a few minutes before calibrating the probe, and also avoiding any light entering before that first black point/patch reading can really help results. It seems to work but I’ve got nothing to compare to.

I’ll keep you posted.

thanks for your answers. I’ll have a look at it next week.
Please keep me updated on your progress Toby!

Thanks again!

Hi Toby, eye one is a probe that need calibration after some measurements. For a full profile you need more than 30min, and I think this is too much for eye one. You can get a profile, but the question is, will it be better or worst than native calibration?…

In the other hand, probes like i1D3 has better over time measurements and can read 0.01cd. If your program can generate a profile matrix to i1D3 from eye one pro, like calman, I recommend you this way. i1D3 is really cheap, and if you generate the right matrix from eyeone it will very accurate. But I don’t know for sure if i1D3 can work with Oled Refresh rate.

[Juan Salvo]

The i1d3 does indeed work with oled. I’ve calibrated 3 oled PVMs this way. Is CRT as the profile type as this will get closest to the performance profile of oled. That is until the calibration companies, realize they need to be ready for oleds.

[Steve Shaw]

Oleds can be a pain, as can Plasmas with their PWM operation.

But, we have done a load of calibrations using Hubble and the cheaper i1 Display Pro using LightSpace CMS with great results.

One thing to look out for is setting integration time of the i1 Display Pro to a value that works with the screen frequency – for example with Plasmas set the integration time exactly N * (1/fpwm); where fpwm is the PWM frequency and N is a relatively large integer (say 100 or so).

Cheers,

Steve

What is the PWM for the Sony OLEDs? (specifically the 2541).

Thanks,

anyone?
