Eizo CG calibration with LightSpace and Resolve

It has been many times that people have asked me how did i get my Eizo calibrated. Now it seemed good idea to write it in post in longer form.

If you get it working then it should be super simple.

But here it goes:

Lets start with description of how things are connected and who talks to who so it would be clear. I have not seen many of those explanatory drawings around so i decided to make one.

Here you see that i have used my Resolve machine as LS “slave” and calibration pattern generator over the network. Mine was connected with wifi but it works also on lan. It is all the same as the machines are in the same network and “see” each other. Be aware that sometimes windows firewall will block LS to talk to network and you need to disable that blocking and / or enable network for LS. HDMI goes from Resolve machine from DeckLink or MiniMonitor to Eizo. Probe that we use with LS is connected to my laptop which runs Win OS for LS to be happy. After all is done in LS we upload out calibration LUT to Eizo directly via USB. You have to see if it was USB1 or USB2 that you had to use for it. I remember configuring it in monitor menu what USB was used and for what. It may be a bit different in your model but see the manual or play with on display menu a bit and i’m sure you will figure it out.

 

Before you start calibration process we assume that you have set your monitor up that white point is D65 i.e 6500 K, brightness 80-120 cd/m2, and gamma 2.4.
We also assume that you do the calibration in the room you are actually working onin brightness sense.

You do that while connected to your dedicated image path that you want to calibrate. Lets say you use HDMI as i did. First of all you probably will want to reset everything and start from the beginning and adjust monitor settings as i described above.

After you fire up LS then we have many icons to choose from.
We are now interested in one that starts Display Characterization.

After pressing DC button next window pops up:

Here we can adjust the things that interest us most. Leave Cube Side to 3D Cube. Side number controls how many samples are measured during the measuring process. I would do full 21 side pass. Also be aware that number of sides i.e. samples taken affects the precision and also time used for the full process. Also leave on “Closed Loop Mode”. It will tell LS to advance in pattern and make next measurement in timely manner.

Next we would go adjust “Probe Options” and “Network Manager”.

In probe options it is important to see that your probe is recognised and work properly, display type is correct and calibrations settings are correct. Press “OK”.

Now start network manager.

Enable network by pressing “Enable” button. If win firewall is blocking you then you probably will not “see” LS later when trying to connect even if the networking in LS works fine and “Enable” goes green.
Just keep it in mind in later steps. Write up or remember IP dress that your LS “master” has in its networking. In my example it was “192.168.6.100”. Close networking window.

Now we need to start Resolve and connect it to LS over network. Start Resolve in any project or default project and go to Color page. Now in menu go to Color > Monitor Calibration > LightSpace.

Now little window pops up with LS network parameters that you have insert manually:

I have here already inserted my ip that i wrote on the paper (192.168.6.100). After that just press connect.
If all good and successful connection then you will see something like this:

Resolve side is done and we have “slaved” it to LS for pattern generation.

We are back on LS machine in Display Characterization menu.

Assuming that everything went well and all the parameters are fine we can start “Measure”. Make sure that the probe is set up correctly and does not lay on the table and is pointed on to your monitor. Before the actual measuring starts little window pops up and asks for “Profile name”. Make it something that you can later identify easily like Eizo 28062015 or any other way that tells you that this is the profile you just created. Sure you could write in the name “the really latest one” but in time it will be confusing with many profiles. Take a minute and think of a system that is clear and descriptive for you.

Depending on your probe and machine it will take hour, two or three to do the probing as i described time and sample number correlations before. Less samples you have less precision you get in measurement levels.

Now after many coffee cups and cakes later all is done.

We now need to do color space conversion. LS has measured your current monitor and saved it to the profile that you named properly for easy recognition. We will convert the results to mach REC709 in our case.

After you pressed dedicated icon for color space conversion new window pops up:

It may seem confusing at first as “Source” has to be properly named profile you just finished and “Target” needs to be REc709 in our case. But if you think of what happens is that your just made profile needs to be calculated to mach REC709 then it should feel “of course this is the way to name it”. Also make sure to choose Peak Chroma or Peak Luma and press “Create New”. When Calculation is done you get small popup saying how accurate the calibration will be. I got full 100%.

We are almost done and just need to upload our new calibration to out CG monitor.

To do that we go File > Upload and get Upload window like this:

Here we can choose the device to be Eizo and monitor ID. Usually you get just one ID number and it is the one we need to use. If you have something already in monitor loaded before even from factory it is good idea to overwrite it and make it “empty” in memory slot so to say. For that check “NULL cube” and press “Upload”. If “NULL cube” upload was all good the you can turn it off again and press “Upload”. And we are DONE!

For my monitor the calibration is stored in CAL3 slot and i have to choose it and make it active to have the calibration to be used. To be sure that we have only one calibration and not to be confused we did factory reset in the beginning.

It also seems that all inputs have calibrations in separate input profiles and slots.

Hope this post helps!
