Unlike other factory settings, the original factory calibration is not very useful after the first few hundred hours, as so much gamma droop has developed in the panels that the projector would be essentially uncalibrated. In other words, restoring the factory calibration will not restore the projector (in terms of the image it produces) to the factory condition.

Yes, I know it won't restore to factory condition, only as a reference to the improvement. Though I forgot about the gamma droop, so of course I'd want a choice to have just the color cal restored.

I think my Spyder meter is giving me a too-warm cal, as I'm choosing the a much colder color temp preset now. I'm gonna restore the INIT file then do just the gamma cal. But it takes 30 mins for the INIT restore, so it's hard to do a quick/easy comparison.

I picked up used spyder5 to re-calibrate my RS420 (over 1000hrs on low bulb). Mainly I would like to fix gamma droop (if any). Since I performed initial calibration with different spyder5, what and how would you guys recommend to calibrate my RS420? I'm planning on using very useful calibration PDF from the previous page :-)


If someone would give me some pointers I would really appreciate it as I did this 14 months or so ago; and my memory is not getting any better :-)


Thank you in advance

Thank you in advance
It’s best to first select the Log Only option in settings and run the calibration. This will show you whether there’s any gamma droop, without actually changing anything.
It also shows the colour temperature that the Spyder5 measured, so you can tell if major changes will be made if you run colour autocal.

Hi,


Finally I got to it... I've used log only as you recommended.

JVC-00x pictures are for IRIS at 0
JVC-08x picture are for IRIS at -8



Please let me know what you think. My bulb is 1100hrs now. Running on LOW.


Thanks in advance

It doesn’t show any visible gamma droop. Also, the measured colour temperatures are around 6400K, so it would be fairly safe to even run colour Autocal when you need to. Looks like a good Spyder.
