Hardware White Point Calibration with external source?

[Django]

Hi guys,

a rookie (me) needs some help with the whitepoint “hardware” calibration of some broadcast monitors.
I own a Datacolor Spyder 5 Express and i would like to “hardware” calibrate the white point of my 8 monitors because they are all a little bit different.

My plan is, to generate a clean white picture in the video mixer and show it at all monitors. Then using the Spyder 5 with the DisplayCAL software to measure and correct/match it to a 6500k white. But how would this be possible with DisplayCAL and an external white source, without using an output of my PC?

Thanks guys!

HCFR + PGenerator on a raspberry pi (HDMI). For SDR patches it could work even with an old pi rev B.
Search for Pgenerator ISO on AVSForum. HCFR uses the same Argyllcms code for measurements as DisplayCAL.

But is very unlikely that you’ll get a visual match by doing a numerical macth with an Spyder5, device is not up to that task unless you also use an spectrophotometer, and spyder5 is so bad that in such situation I’d use only the spectrophotometer.
Anyway if you got a better colorimeter it could the done that way: HCFR + Pgenerator on a raspberry.

I will correct myself. I can also do it using ARgyllCMS comand line and an external pattern generator of your choice, just use spotread
