USB 3.0 ports (blue plastic inserts) put out more power for devices than USB 2.0 ports (white plastic inserts).
Phil, I wonder if too much power could be a problem?
This is great info and prob why I couldn't get my spyder5 to work
Thanks to_shine, glad to hear you were able to get things working. I was actually able to get the calibration to work once (using quality mode), but then every subsequent attempt has crashed with the "connection" error, under normal and fast mode. Interestingly, the calibration is now crashing very early on, during the initial log just after it measures yellow, whereas it was previously crashing much later.I've tried zooming in as far as possible, but get the same error. I'm trying to calibrate the SDR, with Natural picture mode, low lamp. I'm projecting onto a Stewart Firehawk G5 screen, 123", from about 16' away. My room is semi-light controlled, but with light colored walls and a white ceiling. I'm not really sure what levers I have to increase brightness besides setting the lamp to high.
Thank you for the tip!No, I wasn't aware that you could change the brightness setting used during calibration (apart from lamp mode and aperture setting). Just to be sure about this, how do you set brightness for the calibration?Concerning the error message, I was able to run through both red and green gamma measurements even though the two first measurement steps produced 0 values (I used the 20 step "normal" measurement). For the blue gamma, however, the error message pops up. Is this expected? Do all three colors need to have measured zero in one or more steps before giving an error?
I have the same problem using SpyderX on a Surface Pro 2 running Windows 10. Calibrating gamma with the SpyderX crashes really early in the process doing the log section or sometimes at the beginning of the 1st 20 step run. Color calibration with the i1 Pro2 still works normally. I had the screen zoomed as small as it would go. Thankfully I didn't uninstall the prior version 12.0 of the Autocal software and I could complete the gamma calibration with that version. I think it's bad programming or driver issues on this version. If you go to the download section of the JVC website you can still get the old version if you change the end of the url to /JVC_PJ_Calibration12_en_v1_00.zip.
Helloafter a gamma and color calibration in autocal in V12 1.1 I have these coordinates for the colorsI do not understand what they correspond to impossible to find these coordinates in the colorhcfr softwareis it just the offset (correction of the points) to arrive at the standard because I see that the Z of red is at 0 is this normal? thank you
Hellono these measurements are not in hcfr even by changing the xyz, moreover my Red is at 0 so I don't think that these are values but rather a correction compared to the standard values, no?of course the coordonates of color temp is in the hcfr but not a color signal level ?
my pdf file report hcfr with just u autocal v12 1.1 with the i1d3 without any editing in user mode 1 2.2 6500 rec 709 impression anyway
I just don't understand the info from my first screenshot which has Byzaric coordinates and which appear in the screens during measurement and the red has a Z at 0 so for me it's just a catching up of luminance standards or others because my curves after this calibration are practically perfect until the colorchecker without touching up the menu of the jvc n5
