So I calibrated my monitors...

Every precision measuring tool needs periodic calibration, so I'd assume colour calibrators aren't an exception... What do their manufacturers specify?

AFAIK you cannot calibrate them, you can self test them, if they fail, buy another one. They are pretty dumb devices inside... actually X-Rite i1Display Pro inside has a PIC and two combo light sensors, that's it. If you bring those to your local metrological center, they just check the values... that are pretty broad and give you a PASS OK badge. Pretty boring.

This is true. And Ferrum Master is correct when it comes to most of these lower costs colorimeters sold for home use. Professional and military grade meters can be recalibrated. Some come with a [supposedly] accurate color chart you can use to calibrate. But typically, I think it is recommended the budget models be replaced every few years. But then much will depend on how it has been used.

Why does the military need color calibration?

 

[Bill_Bright]

??? Recon, mapping, ID friend or foe and probably a couple 100 other reasons.

any news/pr/local station stuff will show pictures, internal use like sat/drone footage reviews, all done on screens

Going to borrow a calibration tool from work. Ill post all settings when Im done.

All give us your impressions of the display once it is calibrated.

Oh, don't get too upset or frustrated if the monitor's image controls don't let you get perfect calibration. Also, don't be surprised if the display across the entire surface of the display is not precisely uniform or consistent, left-to-right and top-to-bottom, compared to dead center.

Thanks for the heads up. I honestly dont expect much, but hey, if you have access to tools, why not use em.

I have had these Acer 250hz screens for a bit now, but never really calibrated them past the gaming settings. As I am parting out my workstation at the moment, my gaming rig has become my main, which means I need to edit on it. Here are the settings I came up with.

Acer KG251Q Z settings​

Brightness 10
Contrast 55
Bluelight Normal
Blackboost 5
Gamma 2.2
Color Temp Warm
Overdrive Normal
Low Latency On

All other settings were set to OFF. Refresh rate 240hz for both screens (one on 4070 Super, one on Intel igpu).

I have the same monitor and I’ve found that if you calibrate the color to user and turn the green bias to 25 it’s very close to full color accuracy, I’m not sure why but this monitor has a very green heavy picture by default
